The Work Connection and Rationality of Precision Parts Processing

In precision parts processing, other types of work usually connect shaft, sleeve, and disc workpieces before and after turning. The turning process of shaft, sleeve, and disc workpieces is usually completed before milling, as the blank for milling processing. Heat treatment, boring, drilling, bench work, and other processes are usually arranged after milling processing.

The processing technology for special parts such as box workpieces and molds that intersect and connect with other types of work is relatively complex, and there are usually types of work that intersect and connect. During the milling process, there are often heat treatment processes, bench marking processes, boring processing processes, etc. At this time, attention should be paid to the rationality of the arrangement of work types and work types.

In the processing of precision parts, the connection between ordinary milling and CNC milling is used. For mold surfaces and special parts with high precision requirements, CNC machine tools will be used for milling, usually rough machining by ordinary milling machines followed by precision machining, or for parts with low precision requirements by ordinary machine tools or parts with high precision requirements by CNC machine tools. At this time, attention should be paid to the conversion and selection of reference planes, To ensure the correctness and rationality of the milling process.
