Which Processing Is Suitable For CNC Machine Tools And Which Are Not ?

Considering the number and model of CNC machine tools, parts processing cost, production efficiency and other factors, for a specific part, usually only part of the processes are arranged on CNC machine tools for processing, and other processes are arranged on ordinary machine tools for processing, such as processing of positioning holes and positioning datum planes. Therefore, it is necessary to conduct a careful process analysis of the drawings, select the most suitable and most required process content for CNC machining, and give full play to the advantages of CNC machining while ensuring quality and reducing costs.

When choosing CNC machining, it can generally be considered in the following order:

A. The content that cannot be processed by ordinary machine tools should be the preferred content;

B. The processing content that is difficult to process with ordinary machine tools and the quality is difficult to guarantee should be the key selection content;

C. The processing efficiency of ordinary machine tools is low, and the manual operation of workers is labor-intensive, which can be selected on the basis of the surplus capacity of CNC machine tools.

Generally speaking, after the above processing contents are processed by numerical control, the product quality, productivity and comprehensive economic benefits will be significantly improved. In contrast, some of the following processing contents are not suitable for CNC machining.

1) The processing content that needs to be adjusted by the machine for a long time, such as: rough machining of the blank, etc.;

2) The content of the process that is difficult to clamp or completely depends on the positioning to ensure the machining accuracy;

3) Process with uneven material and unstable machining allowance;

4) Holes or other processing contents that require special tooling coordination;

5) For other sporadic parts that cannot be processed in one installation, it is very troublesome to use CNC machining, and ordinary machine tools can be arranged for supplementary processing.

In addition, when selecting and deciding the processing content, the production batch, production cycle, turnover between processes, etc. should also be considered. In short, it should be as reasonable as possible.
