The process of parts processing is a direct change in the appearance of raw materials in order to make it into semi-finished or finished products, the process is called process flow, it is the benchmark of parts processing and precision mechanical parts processing process, the process is more complex.

Precision mechanical parts processing process benchmark can be divided according to different processes: casting, forging, stamping, welding, heat treatment, machining, assembly and so on categories, is the whole parts of the CNC processing and machine assembly process in general. And other such as cleaning, inspection, equipment maintenance, oil seals and so on are only auxiliary processes, turning methods to change the surface properties of raw materials or semi-finished products, the industry's CNC machining process is one of the main processes.

Precision mechanical parts processing process benchmarks include positioning benchmarks, in the CNC lathe for processing when the lathe or fixture used to position the benchmark. Measurement benchmark, this benchmark usually refers to the size or position of the standard that needs to be observed during the inspection. Assembly benchmark, this benchmark we usually refers to the assembly process when the position of the parts of the standard.

Precision mechanical parts processing needs to produce high quality and stable products, in order to achieve this goal, the staff must have a wealth of mechanical processing work experience and excellent technology, it is known that mechanical processing is a fine job, must have excellent technology to do a good job.

Secondly, precision mechanical parts processing process is standardized also determines whether the product is high quality, production and management are bound to need a set of perfect process, the process is for making the perfect product and service. Once again, the production process must focus on communication, whether it is node time or when there are problems, we must strengthen communication, processing plant and equipment manufacturers to communicate is an important condition for good automation equipment parts processing.

Precision mechanical parts processing when the milling machine is widely used in the digital program control of the contouring system, which includes a wide range of process capabilities, simple and reliable and inexpensive phase system. These systems are used by many factories, particularly for controlling the machining of precision mechanical parts in large three-dimensional profiles.

Correct preparation of the control program is one of the main conditions for quality machining of precision mechanical parts. For digital program controlled phase systems, the preparation of the control program is carried out by the use of an automatic program preparation system, the level of quality of which depends to a large extent on the price of preparing the control program.

Other is the manual control equipment when the processing errors, these errors include the process system of accidental errors and system errors, all processing errors in the system error plays a major role, for precision mechanical parts processing as a whole, will cause a series of CNC process system errors.

For example, the gap, there is a gap as a consequence of the machine tool drive chain in the insensitive belt, but does not include the reverse drive chain gap, the amplification factor of the unstable transmission.
