1. Install the diamond tool on the lathe tool holder to make the center of the diamond ball coincide with the center of the workpiece;
2. Set the load of the spring in the tool according to the material and hardness of the workpiece;
3. Rotate the workpiece, manually make the diamond ball contact the surface of the workpiece, feed radially, observe the surface roughness visually, perform a trial machining of the axial cutting tool, measure the roughness value visually or with an instrument, and adjust the indentation amount according to the roughness value. Surface roughness;
4. Rotate the work piece, and process from the feed rate for trial processing in front of the processing section (1mm);
5. After reaching the processing end position, the feed stops, the diamond ball leaves the workpiece, and the processing ends.
