How to control the surface roughness of machine parts processing

In the mechanical parts processing industry, the surface roughness of the workpiece is also called finish, and the roughness of the surface of the precision machined parts is very high. In the machining process of the mechanical parts, how to control the roughness of the machined surface of the parts?

1. Cutting processing amount: It means that the surface processing amount can be appropriately reduced on the cutting feed amount.

2. The selection of tool geometric parameters: from the geometric parameters of the machining tool, the sub-declination Angle can be appropriately reduced and the radius of the tool tip can be increased, and the polishing edge can be ground if necessary, so that the cutting process is easy and the surface roughness can be reduced.

3. Control the vibration of the machine tool: it can be started from reducing the friction and extrusion between the tool and the workpiece, making the tool sharpening, adding cutting fluid and appropriate heat treatment for some good toughness workpiece materials.

4. Choose a reasonable processing technology: in the process of precision mechanical parts processing, the processing process is also very important, such as unreasonable process may affect the processing quality and production efficiency, many precision machining workpieces need to finish the finish requirements after rough machining.

5. Different selection of raw materials: mechanical equipment parts are composed of many different raw materials. According to the different density of raw materials, the selection of tools and machine tools in the processing process is directly related to the surface roughness.
