　　In the process of CNC grinder machining center, it is very important to prevent the CNC grinder machining center from bumping when programming and operating the machining. Because the price of CNC grinding machine processing center is very expensive, hundreds of thousands of yuan less, millions of yuan more, then what are its advantages?

　　① CNC grinding machine does not need complex tooling. If you want to change the shape and size of the parts, you only need to modify the part processing procedure, which is suitable for new product development and modification.

　　② CNC grinding machine has stable processing quality, high processing accuracy, high repetition accuracy, and is used to the processing requirements of high-precision products.

　　③ In the case of mass production, the production power is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection.

　　④ It is difficult to process complex surfaces by conventional machining methods, and even to process some parts that cannot be observed.

　　Because CNC grinder machining center is expensive, difficult to repair, and expensive, many hours CNC grinder machining center operation process collision attack is a certain rule to follow, is able to prevent. For example, grasp some CNC grinding machine processing programming skills, because programming is a crucial part of CNC grinding machine processing, and improving programming skills can largely prevent some unnecessary bumps.

　　To master the programming skills of CNC grinder machining center can better improve the processing power and quality, and prevent unnecessary faults in processing. This requires us to constantly summarize experience and make progress in practice, so as to further strengthen the ability of programming and processing.

　　For example, when milling the inner cavity of the workpiece, the milling cutter is required to return to 100mm above the workpiece quickly. If programming with N50 G00 x0 Y0 Z100, CNC grinder machining center will linkage the three axes, and the milling cutter may collide with the workpiece, resulting in the damage of the cutter and the workpiece, seriously affecting the accuracy of CNC grinder machining center. At this time, the following procedures can be used: N40 G00 Z100; N50 X0 Y0; that is to say, the tool first moves back to 100mm above the workpiece, and then returns to program zero point, so as to avoid collision.
