Comparative Analysis of Three Models of CNC Engraving and Milling Machine

With the rapid development of the machine tool industry, the domestic machine tool industry has increased dramatically, and the number of employed people has also increased. It is easy for professionals to distinguish between machine tools. For many people who have just joined the machine tool industry, there are too many types of machine tools and it is difficult to distinguish them. In the current situation, the editor integrated three models of CNC engraving and milling machine to facilitate the difference.

First figure out the difference between the three models:

First, the CNC milling and machining center is used to complete the processing equipment for workpieces with a large amount of milling. Second, the CNC engraving and milling machine is used to complete small milling, or soft metal processing equipment. Third, high-speed cutting machines are used to complete medium milling and reduce the amount of grinding after milling to a minimum.

An in-depth analysis of the structure of the above equipment can help us make the right choices, and we can analyze them from different angles.

First, from a mechanical point of view. The machine tool is divided into two parts, the moving part and the non-moving part: the work table, the skateboard, the cross flower table, etc. are moving parts, the bed base, the column, etc. are non-moving parts. First, for the CNC milling machining center, non-moving Part of the steel requirements are very good, and the steel part of the moving part is very good. It has the advantage of being able to perform heavy cutting; disadvantages: because the moving parts are equally large, sacrificing machine flexibility, there is no power for small parts and rapid feed. Secondly, as far as the CNC engraving and milling machine is concerned, its non-moving part has good steel requirements, and the moving part of the steel should be flexible, and as light as possible, while maintaining a certain degree of rigidity. The main advantage is that it is relatively small in machining and has high machining accuracy. High-speed machining is possible for soft metals; the disadvantage is that heavy cutting is not possible due to poor steel properties. Finally, in the case of high-speed cutting machines, the non-moving part requires very good steel properties, the moving part requires better steel and is as light as possible. It has the advantage of being able to perform small and medium-sized cutting (for example, a flat-bottom knives of φ10, and a depth of 0.75 for 45 steel (300)); the disadvantage is that it can be used efficiently and at low cost in correct use, and the grinding amount becomes extremely high. less. Improper use will immediately make the scrap of the tool pile up.

Second, from the perspective of numerical control. First, the CNC milling machining center requires a general speed for the numerical control system, and the spindle speed is about 0 to 8000 RPM. Second, the engraving and milling machine requires a high-speed CNC system with a spindle speed of 3000~30000RPM. Third, high-speed cutting machine tools require high-speed CNC systems and excellent servo motor characteristics. The spindle speed is around 1500~30000RPM.

Third, analyze from the programming software. From a software point of view, CNC milling machining centers, high-speed cutting machine engraving and milling machines can use standard CAD / CAM software such as: MasterCamCimatronPEUG. The milling machine usually thinks that the Cimatron tool path is better. The new version of the software fully examines the uniformity of the cutting amount of the tool at every moment, especially the speed and smoothness of the knife entering the moment of going out, and the following difference algorithm at the inflection point. The problem (followingError) makes the results and design graphics more in-depth. The CAD part has just been used in a large number of intuitive 3D solid modeling such as Solidworks and then transferred to CAM software through IGS.
