Precision parts processing refers to the process of changing the external dimensions or properties of the workpiece through various machinery. The machinery required for machining in Shenzhen consists of digital display milling machines, digital display forming grinders, digital display lathes, electric spark machines, universal grinders, machining centers, laser welding, medium wire walking, fast wire walking, slow wire walking, external grinding machines, internal grinding machines, precision lathes, etc., which can be used for turning, milling, planing, grinding and other processing of precision parts. Such machinery is good at turning, milling, planing, grinding and other processing of precision parts. It can process various irregular shaped parts with a machining accuracy of up to 2μm.

Shenzhen precision parts processing specific treatment principles:

(1) In order to ensure the machining accuracy of mechanical parts, it is best to process rough and fine mechanical parts separately. Because during the machining of rough mechanical parts, the cutting amount is large, the cutting force and clamping force of the workpiece are large, the amount of heat generation is large, and the machining surface of the mechanical parts has a more significant work hardening phenomenon. There is a large internal stress inside the workpiece. If the machining of rough and rough mechanical parts is carried out continuously, the precision of the finished parts will be quickly lost due to the redistribution of stress. For some parts with high machining accuracy requirements. After rough machining and before finishing, low temperature annealing or aging treatment procedures should also be arranged to eliminate internal stress.

(2) Rational selection of equipment, rough machining precision parts processing is mainly to cut off most of the machining allowance, and does not require high machining accuracy of mechanical parts. Therefore, rough machining should be carried out on machines with high power and low precision, while finishing processes require high-precision machine tools. Rough machining and finishing are processed on different machine tools, which can not only give full play to the equipment capabilities, but also extend the service life of precision machine tools.

(3). In the machining process of mechanical precision parts, a heat treatment process is often arranged. The arrangement of the location of the heat treatment process is 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 the mechanical parts. In order to eliminate internal stress, such as aging treatment, quenching and tempering treatment, etc., Shenzhen machining is generally arranged after rough machining and before finishing. In order to improve the mechanical properties of the parts, such as carburizing, quenching, tempering, etc., it is generally arranged after the machining of the mechanical parts. If there is a large deformation after heat treatment, the final processing process must also be arranged.
