What is precision mechanical parts processing

Precision machined part machining is the process of changing the size or performance of a workpiece with a processing machine. Generally, the definition of precision machining refers to the processing of each major surface in steps and steps, including workpiece parallelism, surface finish, surface perpendicularity, surface hardness, etc., which can achieve the machining accuracy of the parts and the quality of the machined surface. The requirements specified in the drawings.




Parallelism requirements: It is required to meet the tolerance requirements around the workpiece, such as rectangular workpieces, then the thickness of the four corners of the workpiece must be within a certain tolerance. If the thickness of the four sides does not meet the tolerance requirements, it will not reach Parallelism requirements.

Verticality requirement: It is required to meet the tolerance requirements of the side and the ground of the workpiece. It can be understood as a proper body. From the point of view of the number axis, it is divided into three sides of XYZ. Generally, XZ and YZ are required to meet the tolerance requirements, and the error and the parallelism are required. Generally, it can be processed according to the parallelism requirement.




At the same time, our precision mechanical parts processing is divided into cold working and hot working according to the temperature state in which it is located. Generally processed at room temperature, and does not cause chemical or physical phase changes of the workpiece, called cold processing. Generally, processing at a temperature higher or lower than the normal temperature causes a chemical or physical phase change of the workpiece, which is called thermal processing. Cold machining can be divided into machining and pressure machining according to the difference in processing methods. Thermal processing is commonly used for heat treatment, forging, casting and welding.
