The standards of the precision parts processing industry are very strict, and there are different processes such as cutting in and cutting out in 

the processing process. The size will also have different specific requirements according to the product, and the processing accuracy requirements

 will also vary. Generally speaking, the precision of precision machining is very high, and sometimes it can even be accurate to a micron difference

 below 1mm. If the size difference is large, the product will become scrap and needs to be reprocessed to meet the requirements. This process is 

very time-consuming and laborious. Sometimes all the raw materials will be scrapped, resulting in an increase in costs, and at the same time, the

 parts will inevitably be unusable. Therefore, there are many requirements for precision parts processing.

So what are the requirements for precision parts processing?

(1) Generally, due to the amount of cut, heat generation and cutting force of the parts, the roughness and accuracy of the parts are different. In

 order to ensure the machining accuracy of the parts, it is necessary to process rough parts and precision mechanical parts separately. If rough 

machining and precision machining are performed continuously, the precision of precision machining parts will be lost due to the difference in

 stress.

(2) The rationality of equipment selection. The machining of rough parts does not require high machining accuracy, but the main thing is to 

reduce the machining allowance, so precision machining requires very high-precision machine tools. In the processing route of precision parts, 

heat treatment processes are often arranged. The location of the heat treatment process is arranged as follows: in order to improve the cutting

 performance of the metal, such as annealing, normalizing, quenching and tempering, etc., it is generally arranged before the machining of 

mechanical parts.

(3) Generally speaking, almost all precision parts are processed with heat treatment process, which can improve the cutting performance of metal.

 The processing and manufacturing of precision parts requires not only the accuracy and stability of the machine tool and the accuracy of the tools

 and fixtures to ensure, but also the calibration and measurement of precision measuring instruments. Some are in the process of processing, some

 are after the inspection.

A large number of hot forging forming and warm forging finishing processes of one-fire two-forged parts are the process of directly changing the

 appearance of raw materials into semi-specific products or different products. This process is called the process flow, which is also the benchmark

 for the machining process of the parts. The process flow of the parts is more complicated, and the processing process standards of precision parts 

can be divided into casting, forging, stamping, welding, heat treatment, processing, assembly, etc. according to different processes. The machining

 process of precision parts often refers to the general term of the entire part CNC machining and machine assembly process, while other processes

 such as cleaning, inspection, equipment maintenance, oil seals, etc., turning methods change the surface properties of raw materials or semi-products.

 This process is called CNC Machining, the corresponding switching mode of the middle trajectory of the tool is different, and the precision parts

 system has linear and circular interpolation functions.
