5 Stages of Machining Precision Mechanical Parts

Generally, the parts of precision machinery and equipment are processed and produced, which requires very high precision. Therefore, in addition to understanding the specific requirements of precision machinery parts processing for materials and the common skills of precision machinery parts processing, we should also understand its steps, let me share with you the 5 stages of it.

 

5 stages of machining precision mechanical parts

 

 

1. Rough machining

 

The main consideration is to increase productivity. Most of the machining allowance of each machining surface is removed, and the fine reference is machined.

 

2. Semi-finishing

 

It should remove the defects that may occur after rough machining, and complete the processing of the secondary surface meanwhile. A certain machining accuracy must be achieved in order to prepare for the finishing stage and to ensure an appropriate finishing allowance.

 

3. Finishing

 

In the finishing stage, high cutting speed, small feed and depth of cut are mainly used to remove the machining allowance left by semi-finishing, so that the surface of precision mechanical parts meets the technical requirements of the drawing.

 

4. Polishing

 

Mainly used to reduce the surface roughness or strengthen the machined surface, mainly used for surface processing with high surface roughness requirements.

 

5. Ultra-precision machining

 

Mainly use processing methods such as precision cutting, fine mirror grinding, precision grinding and polishing to make the machining accuracy of the workpiece 0.1-0.01μm, and the surface roughness value ra≤0.001μm.

 

Last few words

 

The five stages of precision mechanical parts processing are from coarse to fine, and the process is gradually refined. After these five stages of processing, it can meet the requirements of customers. Our K-Tek Machining Co., Ltd focuses on the processing and manufacturing of precision mechanical parts. It can process according to customer requirements and produce precision mechanical parts that customers are satisfied with.
