How to improve the surface roughness in precision machining parts?

In the Precision Machining Parts,the factors affecting the surface roughness are mainly cutting dosage, tool geometry parameters and so on. Whether the Brass Precision Machining ,Copper Cnc Machining,Aluminum Precision Machining,Titanium Precision Machining , CNC Five Axis Machining Parts or Ss Lathe And Milling Parts.To improve surface roughness, you need to start from these aspects:

1. Cutting amount
The higher the feed amount, the higher the residual area height and the rougher the part surface. Therefore, reducing the feed amount can effectively reduce the surface roughness value.

Cutting speed also has a great influence on the surface roughness. In the medium speed cutting elastic material, due to the easy to produce the accumulation of chips, and plastic deformation is larger, so the surface roughness of the processed parts is larger. Usually use low speed or high speed cutting elastomeric materials, can effectively avoid the generation of chip tumor, which has a positive effect on reducing the surface roughness value.

2. Tool geometry parameters
In precision parts machining, the main offset angle, sub-offset angle and tool tip radius have a direct impact on the surface roughness of the part. In the case of a certain amount of feed, reducing the main and sub-deflection angles or increasing the radius of the tool tip arc can reduce the surface roughness value. In addition, appropriately increasing the front and rear angles can reduce the cutting deformation and friction between the front and rear tool faces, and inhibit the generation of tumor chips, which can also reduce the surface roughness value.

After solving these problems, the surface roughness problem can be greatly reduced.
