Precision machining is a process of changing the overall dimension or performance of a workpiece with a processing machine. According to the temperature state of the workpiece to be processed, it can be divided into cold processing and hot processing. It is generally processed at normal temperature without causing chemical or physical phase changes of the workpiece, which is called cold processing. Generally, processing above or below normal temperature will cause chemical or physical phase changes of the workpiece, which is called hot processing. According to the difference of processing methods, cold machining can be divided into cutting and pressure machining. Hot processing commonly includes heat treatment, calcination, casting and welding.
For precision parts, the processing is very strict, and the processing procedures include feed and output. There are specific requirements for size and accuracy, such as the number of micrometers plus or minus 1mm. If the size is too wrong, it will become a waste product. At this time, it is equivalent to having to re-process, time-consuming and labor-intensive, and sometimes it will even make the whole processing material scrap, which will increase the cost. At the same time, the parts will definitely not be used.

Precision hardware machining is also known as turning machining of cam machine tool, which uses the track rotation of cam to drive the walking of props to cut. Precision hardware processing has many advantages, such as high efficiency, precision and low cost.
Generally, in the industry, the machining process specification is one of the process documents that specify the machining process and operation method of parts. It is to write the more reasonable process and operation method into a process document in the specified form under the specific production conditions, and use it to guide production after approval. With the innovation of technology, we summarized the following common tips:
