How To Control The Surface Finish Of CNC Machining?

1, Choose the appropriate cutting parameters: CNC CNC machining cutting speed, depth of cut, feed rate and other parameters of choice will directly affect the surface finish. Generally speaking, increase the cutting speed, reduce the depth of cut and feed rate is conducive to improving surface finish.

2, The choice of tools: tool material, edge radius, etc. will also affect the surface finish. The use of high-quality tools, such as high-speed steel tooling, can effectively improve the surface finish.

3, The use of coolant: the use of high-quality coolant can effectively reduce the frictional heat of the workpiece and tool in the machining process, reduce surface roughness, improve surface finish.

4, Increase the number of machining passes: by increasing the number of machining passes, that is, processing the same surface several times, can gradually improve the surface finish.

5, Polishing treatment: after CNC CNC machining, you can use polishing equipment to polish the surface to further improve the surface finish.

6, The adjustment of machine parameters: to ensure that the spindle speed of the machine tool is stable, to avoid spindle jitter, in order to reduce the roughness of the machined surface.
