How to control the surface roughness of machined parts

2022-10-18

In the mechanical parts processing industry, the surface roughness of the workpiece is also known as the degree of finish, the general precision machining parts surface roughness requirements are relatively high, in the mechanical parts processing process, how do we control the mechanical parts processing surface roughness? Here let me share with you!

1. cutting processing amount: it means that the cutting feed can be on the cutting amount, can be appropriate to reduce the amount of surface processing.

2. Selection of tool geometric parameters: from the processing tool geometric parameters, can be appropriate to reduce the sub-deviation angle and increase the radius of the tip of the arc, if necessary, you can grind the trimmed edge. Make cutting and processing easy, reduce surface roughness.

3. Control machine vibration: from reducing the friction between the tool and the workpiece, extrusion, so that the tool edge sharpening, filling the cutting fluid and some good toughness of the workpiece material for appropriate heat treatment, etc..

4. Select a reasonable machining process: the process of precision mechanical parts processing, machining process is also very important, such as the process is not reasonable may affect the processing quality and productivity. Many precision machining parts need rough machining after finishing to complete the finish requirements.

5. Different raw material selection: mechanical equipment spare parts, consisting of many different raw materials processing, according to the different density of raw materials, processing process tool and machine tool selection is directly related to the surface roughness.
