Do you knowCNC precision machiningWhat are the working procedures?
CNC precision machining generally refers to the electronic computer numerical control machine tool control of precision equipment processing, the following by lifei xiaobian to take you to understand the CNC precision processing processes are what?
First, the process distribution of CNC precision machining needs to be considered according to the structural characteristics and vacancy of parts and the standard of positioning and clamping. The stiffness of the parts is not easily destroyed.
1. The processing of the first procedure can not affect the positioning and clamping of the next procedure, and the general high precision parts processing procedures in the middle of the cross also need to be taken into account.
2. Propose the advanced in-line processing process, and then carry out the appearance processing process.
3. According to the same positioning and clamping method or consistent tool processing process, reduce the frequency of repeated positioning and tool change, the frequency of moving pin, can effectively prevent deviation, improve processing efficiency.

4. During the installation of multiple processes, the one with less damage to the stiffness of parts should be assigned first.

Second, the way of cutting tool concentration sorting. High precision parts processing needs to process the required tool division, with the same tool processing parts on any part can be completed, and then with the second and third knife for the rest of its can be completed, can effectively reduce the tool change time, reduce the empty travel time, reduce unnecessary positioning deviation.
Three, according to the processing part of the order. For the processing of more products, CNC precision machining can be divided into several parts according to its structural characteristics, such as internal type, appearance, inclined plane or plan. General first processing plane and positioning surface, and then processing hole, first to a simple geometric shape, and then processing complex geometric shape, advanced positioning of the lower part, reprocessing positioning provisions of the higher part.
Dongguan Lifei Precision Machinery & Mould Co., LTD., established in December 2015, is a mechanical parts factory engaged in manufacturing and assembly services, supporting the processing of all kinds of fixture and precision mechanical parts. Currently, there are several engineers and technicians in various processes.
