Five Methods to Improve the Surface Roughness of CNC Machining Parts

In the machined parts processing, the surface roughness of precision machined parts is relatively high. In the process of machining parts, here are five methods to improve the surface roughness of machining parts.

1. Cutting amount
In cutting feed, can appropriately reduce the amount of surface processing.

2. Select tool geometry parameters
From the machining tool geometric parameters, can appropriately reduce the auxiliary angle and increase corner radius. When necessary, can be grinded wiper. Make cutting easy, reduce the surface roughness.

3. Control vibration of the machine tool
Can start from reducing the friction, extrusion between the tool and the workpiece, sharpen the edge of a knife, add cutting fluid and some ductile workpiece materials to appropriate heat treatment.

4. Select reasonable processing technology
During processing of precision machining parts, process flow is also very important. If the process is unreasonable, may affect processing quality and production efficiency. Many precision machined parts need finishing after rough machining to achieve the finish requirements.

5. Different raw material selection
Mechanical equipment parts, composed of many different raw materials, according to the density of raw materials, the selection of cutting tools and machine tools are directly related to the surface roughness during machining.
