Haas CNC Machine Tool and Fixture Setting and Management

Part I: Workpiece Fixture

The first thing to note: Before placing any type of workpiece holder on the machine table, make sure that the table is clean and free of any chips or other debris. Chips and other debris between the fixture and the machine can damage both. Metal chips stuck between the jig and the table may cause the jig to shake, and the parts that are machined will also have large errors. Also make sure that all equipment installed on the bench is kept clean.

You must use honing stone to sand the positioning surface. This ensures that the positioning surface does not have any burrs or joints that may damage the table. If the workpiece holder is to be left on the workbench, apply a small amount of anti-rust oil or WD-40® to avoid rust and corrosion of the table and workpiece holder.

When setting up a Haas CNC milling machine, you first need to determine how to fix the workpiece on the machine. There are three basic types of workpiece fixtures in milling operations: vise, clamps, and chucks. The most common method of fixing a workpiece on a machine tool is a milling machine vise. For accurate machining, the clamping surface must be parallel to the X or Y axis when setting up the vise. This operation can be achieved through indicators. Follow the simple procedure below to quickly and easily measure the mill vise.

1. Mount the milling machine vise on the workbench and place the T-nut and bolt in place.

2. Fasten the bolt on the right side of the vise by slightly tightening the bolt on the left side.

3. Place the magnetic base anywhere on the bottom of the Z-axis head. To ensure accurate display readings, the magnetic base should be mounted on a solid part of the head. Slow down the machine shaft so that the head of the indicator reaches the right side of the vise on the clamping surface you wish to measure. Look at the head of the indicator so that its dial shows the reading and set the zero.

4. Slowly move the indicator across the entire clamping surface and stop at the left side of the vise. To determine the direction in which the vise needs to move, tap the vise until the indicator returns to zero. Note: The right side is bolted tightly and the vise will rotate around this point. Slowly return the indicator to the right side of the vise and reset the zero point. Slowly return to the left and tap the vise until the indicator shows zero. It should now be very close to the parallel position. Repeat the above steps until the indicator remains at the entire surface.

5. After displaying a uniform reading on the entire vise jaw, first tighten the left bolt and then tighten the right bolt. Finally move the indicator over the entire surface to ensure that it is still parallel to the machine travel.

Tip: Use a mallet or champagne hammer to tap the fixture or vise into place. Using a ball axe hammer or other hard object may damage the fixture.

Make sure to place the workpiece in the center of the vise when positioning the workpiece in the milling machine's vise. The majority of the workpiece should not be hung on the side of the vise. This can cause the moving jaw to twist the workpiece, which greatly reduces the clamping force. If you try to drill a hole in a hanging part, Z-axis thrust may cause the drilling point of the part to depress and the other side of the part to lift. If you need to drill a hole in a workpiece in a vise, use a stepped jaw. Stepped jaws can be used to suspend the workpiece and leave the bottom of the vise. This allows clearance under the workpiece to avoid drilling into the vise when drilling through holes. If you have only hard steel jaws and no stepped jaws, use a set of parallel bars in the vise to secure the workpiece away from the bottom of the vise. It must be checked whether the parallel bars are the same size to ensure a smooth workpiece setting.

Tip: Most high-precision milling vises have keyways and keys on the positioning surface. Since all Haas milling machines are equipped with high-precision T-slots aligned with the X-axis, you can use the keys on the vise to position the vise in the T-slot. This ensures that the vise is perpendicular to the table. If your vise does not have a configuration key, you can use a vise bottom plate (key or pin at the bottom) to position the T-slot. At the top, a series of holes can be machined to attach the base plate to the machine table and threaded holes can be used to attach the vise to the base plate. The bottom plate is positioned in the T-slot and bolted to the table. Install a vise on the base plate and check the parallelism as described above. Now, each time you use a vise, you only need to position the base plate in the T-slot and use bolts to fix it. In high-precision machining, the parallelism must still be checked and a small amount of adjustment must be made.

When using clamps to hold down parts by pressing downwards, it must be ensured that the clamps are lowered to make contact with the parts and rise back when returned. Most push-down clamps use screw jacks or saw-tooth blocks that mesh with serrations on the clamp to support the end of the clamp, which is the end opposite the contact member. The serrated end of the clamp must be higher than the clamp contact end. Otherwise, the clamp will touch the edge of the part, not the top. This can greatly reduce the clamping force used to secure the part and can cause dents at the top surface to side joints of the part. If screw jack type clamps are used, make sure that the screw jack does not rest directly on the milling table. Thicker pads or other materials must be used to protect the milling table.

Tip: When using clamps in production, check the adjustment of screw jacks regularly to ensure that one end of the clamp screw jack is higher than the contact end. In any case, the fixing bolt should be placed as close as possible to the clamped workpiece in order to transmit the maximum clamping pressure.

When a cylindrical surface needs to be clamped, it may be best to use a 3-jaw chuck mounted on the machine table.

Tip: If the cylindrical surface has been machined, a set of soft jaws should be installed on the chuck. Use an end mill to machine the jaws until the exact diameter of the surface you wish to clamp is reached. It should be remembered that when the jaws are machined, the chuck must be clamped. It is best to use a bar or hex nut - just make sure the jaws are tight and leave room for the cutter to cut to the desired depth. This can also be done if you are working on a soft jaw on a milling machine vise. The vise must be clamped before performing any machining operation.

Part II: Setting Offsets

In many cases, CNC programmers set the Z-axis zero at the top of the material in the program. But usually the surface of the raw material is not flat and it is not completely parallel to any axis.

Tip: If you need to set the tool length offset from the top of the material, and you need to get accurate tool length values, lightly pass the material over the material. This allows the tool to be measured from a flat, clean surface. You can also set the tool length offset from the fixture used for the fixed part, and then gradually increase the Z-axis workpiece coordinate offset value to a positive value and equal to the part thickness.

When setting the tool length offset, feed the tool toward the zero point of the Z axis. When approaching, insert a piece of paper between the tool and the workpiece. Carefully move the tool down until the top of the part is as close as possible, but the paper can still move. Switch to minimum increment in handwheel jog mode. Pull paper back and forth while slowly moving down. You will begin to feel the tension on the paper. Press the OFSET button, then press PAGE UP until you reach the CLNT (LENGTH) (RADIUS) page of the corresponding setting tool.

Place the cursor in the GEOMETRY column and move it down to the tool number being set. Press TOOL OFSET MESUR. The control device reads the Z-axis absolute machine position recorded at the bottom of the screen and enters it as the tool length for the corresponding tool number.

Tip: When setting the TLO (tool length offset), if pressing the TOOL OFSET MESUR button is pressed, the Z-axis absolute machine position should be recorded. Otherwise, the setting 64 in the control device should be turned off.

When setting the workpiece coordinate offset, you must accurately position the X-axis and Y-axis zero points. Remember that you are measuring a spindle centerline and a position on the workpiece or fixture. If you are measuring the edge of a workpiece or fixture, the most common tool is the edge detector.

The edge detector consists of two concentric cylinders connected together with springs. In use, the edge detector is placed in the collet chuck and is slightly offset by two halves so as to be wobbled during rotation. Then push the part slowly into the swinging end of the edge detector. The edge detector will center upwards and suddenly lose concentricity. At this point, slowly move the edge detector along the positive Z-axis and raise it above the workpiece. Now jog the positioning axis, moving the distance equal to the radius of the edge detector. Make sure you are on the page labeled "WORK ZERO OFFSET" and the cursor is on the correct line in the G CODE (G54, etc.) column. With the cursor over the correct axis, press the PART ZERO SET button and confirm that the correct column is entered.

Tip: If you are setting the TLO from the workpiece, you only need to set the offset of the workpiece coordinates for the X and Y axes. Z-axis workpiece coordinate offset can be compensated by tool length offset.

Tip: When using an edge detector, a spindle speed of 1000-1500 rpm is suitable.

Indicol is a useful tool if you need to find the centerline of a hole or a circular part. This is a fixture of a dial gauge. C-clips are provided to connect Indicol to the tool holder in the spindle of the machine. Indicol also has two or three adjustable arms, and a clamp at the end to fix the dial gauge. The adjustable arm can be used to position the indicator so that the rotating diameter is the same as the aperture.

To find the centerline of the hole, position the indicator head over the hole and then manually rotate the knife holder. It can be checked whether the rotation diameter of the indicator head is approximately the same as the aperture, and the eccentricity of the current position is determined. Adjust the X and Y axes as close as possible before moving the indicator down into the hole. Once close, slowly lower the Z-axis so that the head of the indicator enters the hole and adjust the arm so that the indicator shows the reading. Rotate the indicator so that it touches the surface of one of the four quadrants (X+, X-, Y+, or Y-). Now set the indicator zero and rotate 180 degrees. The indicator's movement distance is twice the adjustment distance of the axis. If your indicator moves 0.016 in the negative direction, the jog distance in the positive direction of the axis is 0.008.

The indicator now rotates 90 degrees and resets the zero point. The indicator rotates 180 degrees to find the distance and direction that other axes need to adjust. Remember, in order to find the centerline of the hole, the indicator moves twice the shaft jog distance. For smaller apertures, this procedure is more difficult but very accurate. In each axis, you can find the exact centerline of the hole with an error of no more than 0.0001 inch.

Tip: Coaxial indicators can save a lot of time when looking for holes and the centerline of a circular part. This indicator is mounted in the collet chuck and is used during spindle rotation. Manufacturers claim that these indicators can be used for speeds up to 800 rpm, but are ideal for 50 to 100 rpm range; if the spindle speed is too high, it is difficult to tell which axis needs to be adjusted. The fixed arm keeps the indicator surface stationary during spindle rotation. Each time you rotate the spindle, the indicator dial will show its eccentricity. You only need to jog the machine axis while observing the movement of the indicator. Even if the indicator's eccentricity is as high as 0.250 inches, the rotation can be started and the adjustment can be completed in a few seconds, thus saving time.

The third part: knife holder

Choosing the right tool holder is just as important as choosing the right tool. For all machining occasions, the shortest possible tool holder should be selected. In addition, the tool should be set in the tool holder to increase the distance as much as possible. This increases the clamping force of the tool holder on the tool and reduces vibration. The shorter the distance between the spindle head and the tool tip, the better the rigidity of the entire device. When cutting, increased rigidity means less vibration. Haas Automation Machinery recommends that the balance of the tool carrier at speeds up to 10,000 rpm or higher be in compliance with G2.5 or higher (at maximum speed). You can use a pre-balanced tool holder, but it should be balanced again when installing the tool in the tool holder.

The tool in the tool holder should be provided with sufficient support, only a small part of the support

Tip: Balancing the tool holder will only improve machining conditions. The spindle and tool life can be extended, as well as the surface quality and dimensional accuracy of the components. If the blade balance of the mounted tool does not meet the requirements of the G2.5 specification, poor workpiece surface quality may result and the spindle may be damaged.

Tip: If the spindle speed is required to exceed 10,000 rpm and the tool holder must be balanced, the end mill holder with set screw should not be used. Because the set screw produces a one-way clamping force, the end mill holder does not allow the tool to operate normally (concentric to the spindle). The most suitable tool holders for high-speed applications are shrink-fit tool holders, collet chucks (with balance nuts), and collet chucks or hydraulic chucks. These knives produce a uniform clamping force on the tool, so the TIR is almost zero.

Tip: For high-speed machining, round shank tools should not have a Weldon plane. The Weldon plane loses its balance due to uneven weight distribution. The tool length extending from the tool holder should be as short as possible.

Part IV: Cutting Tools

When selecting a cutting tool, first consider what you need to do. Here is a brief description of the most common basic tools for milling operations.

drill

The drill bit is used to machine a cylindrical hole in the workpiece. Drill holes can be through holes or blind holes. Blind holes are holes that do not completely penetrate the workpiece. In general, engineering drawings will specify that a hole needs to be drilled to the “OD depth”. This means that the hole diameter must be a specified depth, regardless of the angled head of the drill. In measuring the tool length offset, the length of the drill and its head is measured. So what should be the depth of the hole to get the correct depth of the outside diameter? You need to know the length of the drill tip.

Tip: The length of the drill tip depends on the blade angle and the drill diameter. The length of the drill tip is obtained by multiplying the drill diameter by a certain constant; the value of the constant depends on the angle of the drill tip (the angle of the drill tip of most standard high-speed steel drills is 118 degrees).

For drill angles: 118 degrees 135 degrees 141 degrees Drill diameter multiplied by: 0.3 0.207 0.177

Use these constants to calculate the length of the drill tip. The error is only a few thousandths of an inch.

Center drill

The center drill is a small drill with a guide point. For the processing of small diameter holes, the wall of the hole is tapered.

If the position of the hole must be kept to a small tolerance, the center drill should be used first, then the twist drill should be used. The center drilled tapered wall maintains the twist drill aligned as it begins to drill into the workpiece.

Tip: Many machine tools use this empirical method: If the diameter tolerance of the center hole is not important, the drilling depth should be increased as much as possible. Below 0.375 inch diameter, the hole diameter machined using a standard 60 degree center hole will be close to the drilling depth. For larger center drills - 0.375 inches or more - the ratio of depth to diameter is greater, so the deviation may be 0.080 to 0.100 inches.

Reamer

The reamer is used to remove a small amount of material in the borehole. Reaming drills can achieve a very narrow range of bore diameter tolerances and achieve extremely high surface quality. The hole should be drilled first, leaving a 0.005 to 0.015 inch allowance on the hole wall and then removed by the reamer.

Tip: When reaming, the best state of hole size and position accuracy is to follow the following steps: first drill, then boring, and finally ream.

Tip: The allowance for reaming depends on the aperture. Under normal circumstances:

For holes smaller than 1/2" for hole diameters greater than 1/2" the hole diameter is less than 0.0150"
The margin is 0.030"

The type of workpiece material and the machining method of the hole all affect the machining allowance.
Tip: The most accurate and uniform surface can be machined when using the G85 (entry, boring) fixed cycle to access the reamer. Many people are trying to save time using the G81 (drilling) canned cycle, which will quickly exit after the knife is fed. Its processing speed exceeds G85, but it usually produces a spiral mark on the cylindrical surface of the hole. Although this trace is very slight and does not affect the size of the hole, some customers will reject it because of the appearance of the hole.

Tap

Taps are used to machine threads in boreholes.
Note: Special care must be taken when tapping with a milling machine.

Tip: If you are using a machine that can perform rigid tapping, the feed rate (inches per minute) = pitch x rev/min. In addition, tapping dimensions must not exceed the outer diameter of the 1.5 x tap. If the contact length exceeds 1.5 times the diameter of the fastener, the strength of the threaded connection will no longer increase. If you need to increase the thread depth, first use the machine tapping, and then manually tap to the final depth. If the depth exceeds 1.5 x pore size, the possibility of cracking the tap increases significantly. Chip control is more difficult. When tapping in a blind hole, it must be drilled to the maximum depth as possible to avoid squeezing the chips under the tap. Use spiral groove taps to pull chips out of tapped holes. To further reduce the difficulty of tapping, make sure that all holes that need to be tapped are free of chips and use tapping fluids that are specific to the material being machined.

Tip: The drill hole size is the specified hole diameter for a particular tap. For a 75% active thread, the formula used to determine the correct hole size is:

D – 1/N, where
D = outside diameter of tap
N = number of threads per inch

Thread depth of 75% thread depth, the strength is only 5% lower than the threaded hole depth of 100% thread, and the cutting force is only 1/3.

End mill

The end mill is shaped like a drill but has a flat bottom. It is mainly used for cutting on the side of the tool and machining the contour of the workpiece.

Note: When using the tool compensation functions (G41 and G42) to program end mill contour cutting or pocket tool paths, it is very flexible to adjust the size of the machining area. Use the tool compensation function to adjust the cutting amount of the raw material. When the end mill wears, a small amount of offset adjustment ensures that each part has the same size. You can also use different sized cutter heads to allow the machine to cut the same part sizes along the previously set tool path.

Round nose cutter

Round nose end mills are the same as ordinary end mills, but have a radius at the corner where the groove meets the bottom of the end mill. The radius can reach up to half the tool diameter.

Tip: The round nose end mill is very effective when machining the roundness between the wall and the floor. And it can increase the strength of the end mill. When machining hard materials, the sharp corners of standard end mills are susceptible to chipping and wear faster than round nose end mills. The radius of the round nose cutter is more gentle when cutting into the workpiece.

Spherical milling cutter

A ball cutter is a round-nose end mill with a fillet radius that is exactly half the tool diameter. This makes the shape of the tip exactly spherical. It is also possible to cut the side of the tool like an end mill.

Tip: The main purpose of a ball mill is to machine lofted surfaces. The spherical profile of the tool can move along any undulating surface and can cut anywhere along the "spherical end" of the tool. Since the ball can roll on the surface, a ball milling cutter can be used to cut any such surface.

Cogging end mill

The cogged end mill is the same as the standard end mill but with a replaceable carbide insert.

Tip: Cogged end mills are used to cut metals other than hard metals at higher speeds. This tool has a wide range of diameters, enabling greater depth of cut. This is very useful, but when using these tools, it is best to calculate the power required for cutting. This is a piece of cake on the Haas control device: There is a button labeled "HELP/CALC" on the front panel. Press this button to open the help menu and press again to open the calculator function. Use the PAGE UP/PAGE DOWN button to scroll through the following three pages: Trigonometry Help, Circular Interpolation Help, and Milling Help. Each page has a simple calculator in the upper left corner. On the Milling Help page, three equations can be solved:

1. SFM = (tool diameter [inch]) * RPM * 3.14159 / 12
2. (Chip load [inch]) = (feedrate [inch/min]) / RPM / number of slots
3. (Feeding speed [inch/min]) = RPM / (pitch)

When using these three equations, you can enter known parameters and the control device will calculate and display the remaining unknowns. When calculating the power required for cutting, you must enter RPM, feedrate, number of slots, depth of cut, cutting width and select a material from the menu. If you change any of the above values, the calculator automatically updates the power required for cutting.

The next thing to consider when choosing a tool is the material being cut. The most common cutting materials in the metalworking industry can be divided into two categories: non-ferrous and ferrous materials. Non-ferrous materials include aluminum and aluminum alloys, copper and copper alloys, magnesium alloys, nickel and nickel alloys, titanium and titanium alloys. Common iron-containing materials include carbon steel, alloy steel, stainless steel, tool steel, and iron-containing casting materials such as cast iron. Non-ferrous metals are relatively soft and easy to cut, with the exception of nickel and titanium. Iron-containing metals are usually hard and difficult to cut.

Tool material is the most important factor to consider when selecting a tool. Most of the above tools use three basic materials: high-speed steel, carbide, and carbide inserts. Almost all of these basic tool materials can be used to cut a variety of materials. The difference is only in performance. High-speed steel cutters have very high hardness but poor wear resistance. Carbide wear is very good, but it is easy to break. Cemented carbide is suitable for cutting materials at higher speeds and feed rates, but at a higher price. Carbide insert cutters are ideal for high volume production because there are multiple cutting edges on each cog. After one of the cutting edges is worn, you can index to the other cutting edge. After all the cutting edges have been used, only the cogs are replaced, not the entire tool.

Tip: If you are using a high-speed steel drill, you must first use the center drill. Then drill. This ensures the correct position of the drill hole. If you are using carbide drills, it is not necessary to center the drill first because carbide drills are equipped with self-aligning tips. If you use carbide drills to drill holes that have been center drilled, you can damage the drill. The outer cutting edge contacts the tapered wall before the bit begins to cut. This will cause impact on the external cutting edge and cause the drill bit to crack. Carbide drills must first start cutting from the tip before using the outer cutting edge.

These tool materials can use a variety of different coatings to improve its performance. The three most commonly used coating materials at present are titanium nitride (TiN), titanium carbonitride (TiCN), and titanium aluminum nitride (TiAlN). The gold of TiN coating is very easy to identify. The advantages of TiN coatings are higher surface hardness, longer tool life, better wear resistance, and better lubricating properties that reduce friction and reduce edge build-up. TiN coating is mainly used for processing low alloy steel and stainless steel. Compared to TiN, the TiCN coating is gray and has a higher hardness. The advantages are higher cutting speed and feed rate (40% to 60% increase compared to TiN), faster metal removal, and excellent wear resistance. TiCN coating can process all materials. The TiAlN coating is grey and black and is mainly used for machining hard alloys. Suitable for very high processing temperatures up to 800 °C, making it ideal for high-speed machining without coolant. Compressed air is recommended to remove chips from the cutting area. This tool is ideal for hardened steels, titanium, and nickel alloys, including abrasive materials such as cast iron and high-silicon aluminum.

When selecting an end mill, the number of grooves or the number of cutting edges is an important factor. The more slots in the end mill, the smaller or narrower the slot size. The center solid part of the double slot end mill is approximately 52% of the end mill diameter. The center part of the three-slot end mill is 56% of the diameter, and the center part of the four-slot or more-number-end mill is 61% of the diameter. This means that the greater the number of slots in the end mill, the higher the rigidity in cutting. Two-slot end mills are recommended for softer viscous materials such as aluminum and copper. Four-slot end mills are recommended for harder steels.

Part 5: Cutting Speed ​​and Feed Rate

Cutting speed refers to the speed of the tool's cutting edge relative to the workpiece in feet per minute (SFM). The feed rate refers to the speed at which the workpiece enters the tool in inches/minutes (IPM) (or millimeters). The feed rate and cutting speed will affect the completion time of the cutting, the service life of the tool, the quality of the machining surface and the power required by the machine tool. The cutting speed mainly depends on the material to be cut and the tool material. To calculate the correct spindle speed (RPM/minute RPM), multiply the SFM recommendation by 3.82 and divide by the tool diameter. 3.82 is a constant that converts SFM to RPM. The feed rate depends on the width and depth of the cut, the required surface quality, and many other variables. The required feed rate = feed per tooth × number of teeth × spindle speed.

Tip: Refer to the Mechanical Manual © or other reference materials to calculate the correct speed. Most tool makers can provide general tool instructions based on the cutting material required. Many manufacturers even provide on-site services to help you choose the right tool, coating, and cutting speed.

Tip: Although the tool speed and feed rate reference provided by the manufacturer can be used for your convenience, it is for reference only. In many cases, these numbers apply to the ideal situation and are therefore not necessarily suitable for practical applications. Experience is very important when adjusting tools based on cutting conditions. Vibration may occur during cutting, so it may be necessary to change the cutting speed and feedrate to eliminate these phenomena.

Tip: The Haas control device has a standard calculator function that helps the operator perform triangular, circular interpolation and milling calculations. To use these functions, simply press the HELP/CALC button twice, then use PAGE UP or PAGE DOWN to select the calculator you want to use. Enter prompt data and the control device will calculate it on its own.

To set up a CNC milling machine in the shortest possible time so that it can process the highest quality parts requires attention in two areas. First of all, you need to have sufficient common sense. Second, we should be proficient in all aspects mentioned in this article. Many resources can provide useful information on these aspects. Haas Automation's application department can answer all your questions about Haas machine tools and some of the problems you may encounter during processing. In addition, tool makers can also provide consulting services for their products. Finally, you can find a lot of information on the Internet.

Part 6: Automatic Tool Management

The user can use the Haas control device to monitor the machine function and record the data of the tool used by the machine tool. The control device can monitor the tool according to the tool number, and record the spindle load, feed time, and the use of each tool. At the same time, this information is saved for the user to use.

Tip: The tool load page is located in the current command display (in whichever mode, in the current command display, press PAGE UP once to switch to the tool load page). Setting 84, Tool Overload, will determine the machine's response to tool overload. There are four options for Setting 84: Alarm, Feed Pause, Buzzer, or Auto Feed. The machine will respond when the spindle load exceeds the value entered in the LIMIT% column of the tool load screen. If the tool does not set a limit, the machine will not respond.

Setting 84 can be used to prevent common problems that may occur during processing. E.g:

Worn tools and cogs may also increase the spindle load. Monitoring the spindle load helps the operator determine when the tool or cog should be changed.

If the coolant is insufficient, it may cause the material to stick, or the cutter may get swarf, which will hinder the chip removal and affect the cutting action of the cutter. It may also lead to an increase in the spindle load; therefore it is also useful to monitor the load by the machine in this case.

If the cutting depth or width is not uniform, the spindle load will only be added to the specific part. Selecting Auto Feed in Setting 84 will reduce the machine's feedrate to maintain the maximum value set on the Tool Loads page. Parameters 299, 300, and 301 control deceleration and recovery time.

Tip: Keeping the tip of the tool increases the speed of production. Track the performance of a particular tool over time. This information can be used to limit the number of times the tool is used after knowing the number of times the tool can machine parts (while maintaining availability). For example, if you know that a tool cannot be used after 27 uses, you can enter 25 or 26 in the alarm field on the Tool Life Screen (current command page; press PAGE UP twice). After 25 or 26 uses, the machine will generate alarm 362 and the tool will use reset. At this point, the operator can press RESET to clear the alarm, replace the cog or tool, and zero the number of times the tool was used in the Number of times column in the tool life screen.

Tip: To clear the values ​​stored in the Tool Load and Tool Life Screen, move the cursor to the corresponding line and column and press the ORIGIN button on the keypad. If you want to clear all the data in the bar, move the cursor to the top of the bar and press the ORIGIN button.

Haas Tool Bracket System

The Haas Tool Bracket System is mounted on the back of the machine for easy access to commonly used tools. The size of the tool holder is 45" x 19" for most vertical and horizontal machining centers.

The system is equipped with a bracket and tank. Additional tool trays and tool boxes can be ordered separately.

Each carrier has a maximum load capacity of 120 lbs.

Vertical space: There are six 40-taper trays or five 50-taper trays (tool holders are empty) on the tray.

Palisade Fence

QYM-Palisade fence

It is widely accepted as the industry leader to protect and deter general attack from all types and conditions of intrusion. Palisade fence is constructed using a post, rail and paling system. The security level of the fence can be increased by increasing the height of the fence, adding the pale numbers of each panel or increasing the thickness of the pale. The pales are made from hot formed and cold rolled steel belt,These belt offer both strength and rigidity combined with a long life span.
