A spherical diamond fixed on the cutter body performs friction rolling on the surface of the workpiece. When the force exceeds the yield point of the material, the surface of the workpiece will flow microscopically and fill the adjacent valleys to make the metal surface rough. Reduce, but also improve the wear resistance and fatigue strength of the metal surface.
Technical advantages of outer diameter diamond rolling cutter tools
1. The spherical diamond slides across the surface of the workpiece under spring load, thereby obtaining a hardened smooth surface and ensuring that the precision and tolerance of the workpiece will not be damaged;
2. The outer diameter diamond rolling cutter can roll small diameter parts and thin-walled parts;
3. It can process workpieces with hardness knife hrc60;
4. Since the diamond ball is in point contact with the surface of the workpiece, it can be used for processing of various shapes, such as: outer circle, inner hole, end surface, inclined surface, spherical surface;
Instructions:
1. Install the outer diameter 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, try to process a section of axial cutting, measure the roughness value visually or with an instrument, adjust the indentation amount according to the roughness value, and achieve better 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.
