The CNC machining is the most common prototype processing, then how to complete the CNC prototype production, it has what four stages? Duochuang prototype will discuss these with you.

The four stages of CNC prototype making are mainly reflected in the following:

1. Rough machining. Rough machining is mainly to remove most of the machining allowance on each surface, so that the shape and size of the rough embryo is close to the finished product. It is characterized by the use of high-power machine tools, the selection of large cutting with children, as far as possible to improve productivity and reduce tool wear.

2. semi-finishing. Semi finish machining is the finishing of secondary surfaces and preparing for the finishing of primary surfaces.

3. Finish machining. Finish machining is to ensure that the main surface to meet the requirements of the processing pattern.

4. Finishing cut. Finishing cut is not only the surface roughness machining precision requirements, but also need to carry out finishing machining. This stage is generally not used to improve the accuracy of parts position.

It should be pointed out that the division of the processing stage is on the whole process of parts processing, not to a surface processing or the nature of a process to judge.At the same time in the specific application, can not be absolute, for some heavy parts or small allowance, precision is not high parts, can be in a clamping after the completion of the surface of the rough finish.

Duochuang prototype is a professional manufacturer engaged in prototype processing, CNC prototype production, and we have 7 years of rich experience in prototype processing.
