The key factors of precision parts machining technology are multifaceted, including mechanical equipment, tool technology, process parameters, machining accuracy control, worker skills, etc. The following will provide a detailed introduction to these key factors.

Firstly, mechanical equipment is one of the important factors affecting the machining quality of precision parts. Modern CNC machine tools have advantages such as high speed, high precision, and high rigidity, which can meet the requirements of precision part machining. The spindle accuracy of machine tools, the decision-making accuracy of instruction systems, and the stability of various auxiliary devices all have a significant impact on machining quality.

Secondly, tool technology also plays a crucial role in precision machining of parts. The quality of cutting tools, material selection, geometric shape design, and grinding techniques all affect machining accuracy and surface quality. Reasonably selecting suitable cutting tools and using and maintaining them correctly can improve cutting efficiency and machining quality.

Thirdly, the selection and control of process parameters are key steps in precision machining of parts. The clamping method, cutting speed, feed rate, cutting depth, cutting lubrication method, etc. of the workpiece will have a significant impact on the machining quality. Reasonable selection and control of these process parameters can reduce machining errors and surface roughness, and improve machining accuracy.

Fourthly, precision control is an essential factor in precision machining of parts that cannot be ignored. The accumulation of processing errors can lead to inaccurate part dimensions and shape distortion. Therefore, it is necessary to ensure machining accuracy through precision control measures, such as the preparation of process specifications, the development of machining process cards, the calibration and use of measuring tools, etc.

Finally, the impact of worker skills on precision parts machining is also important. The experience level and skill level of workers are directly related to the quality of processing. Workers need to have rich knowledge and experience in mechanical processing, be proficient in operating machine tools and cutting tools, and have the ability to analyze and solve problems during the processing.

In summary, the key factors of precision parts machining technology include mechanical equipment, tool technology, process parameters, machining accuracy control, and worker skills. Only with the coordination and cooperation of these factors can high-precision and high-quality precision machining of parts be achieved.
