high precision parts processing is small and delicate, no matter from the material and process, are very heart of the process of production, not batch production of parts, but also belongs to a kind of mechanical processing. For high precision parts, the machining is very strict. The high precision parts also represents one of the foundations of enterprise development competitiveness, in high precision machining workpiece processing requirements are generally used in the form of CNC precision machining of parts.Machinery processing plants in precision processing, not only to meet the customer's workpiece processing technical requirements, with the required performance at the same time should pay attention to the improvement of production efficiency and worker efficiency, so as to bring more economic and long-term effective service for customers.

1) First of all, received the customer drawings processing requirements, before the start of high precision mechanical processing, to choose the appropriate CNC machine tools, write several sets of processing procedures economic, good benefits of the program. Mechanical processing quality request high appearance, are divided into processing stages, generally can be divided into rough processing, semi-finishing and finishing three stages. Mainly in order to ensure the processing quality; Conducive to scientific application equipment; Easy to arrange heat treatment process; And to facilitate the detection of blank defects.


2) Then develop appropriate CNC/ machining schemes for precision parts. Analyze the drawings of the machined parts, making the machined parts and apply appropriate machining techniques.
3) Secondly, the choice of material hardness. For some occasions, the higher the hardness of the material is better, but limited to the hardness requirements of processing parts, material soft and hard moderate, at least to lower than the hardness of parts. Therefore, the most basic one is that we must pay attention to the density of the material before processing.


4) Then in the processing of high precision parts is important to write and design the process flow, because parts processing procedures, the selection of benchmark, the selection of processing tools, fixture selection and installation and processing strategy and process parameters are determined, affecting the quality of the product.


5) Finally, in the process of processing high-precision parts, we should also pay attention to the full inspection of product quality, and then arrange shipment. If it does not meet the requirements of the drawings, the secondary processing will meet the requirements of size, accuracy, tolerance, technical parameters and so on.
