How to process the smoothness of CNC lathe to 0.8?

The machining smoothness of the machine tool is related to the material itself, the accuracy of the machine tool, the choice of tool type, the grinding of tool angle and other comprehensive factors. However, it is impossible for ordinary tools to achieve a finish of 0.8. For the introduction of high-speed shaver, please refer to the mechanic (cold working).

The tool can achieve a surface finish of 0.8 or higher for the excircle.

But we need to do some preparatory work.

1, the speed should be increased according to the size of the workpiece, and the feed should be reduced appropriately.

2. Choose a reasonable tool.

3. Choose a reasonable feed.

Extended data:

What ensures the stability of the lathe is whether the lathe is fixed; Then there will be jitter when the spindle runs at high speed.

Coolant is very important; Then, the tool should be well ground, and the chip removal groove should be well opened to prevent the workpiece from being scratched due to poor chip removal. When chamfering, the turning tool should be made into an arc angle, and in addition, don't resist the tool when loading the tool;

Finally, it is necessary to match the spindle speed and feed speed. If the lathe doesn't work well, it is recommended to buy some sandpaper to make it. When making sandpaper, it is suggested to treat it according to the working direction of the turning tool, so that the processed lines will look better.
