Product description: After the tool is finely ground, the name of a process before coating is not unified at home and abroad. ” or “ER (Edge Radiusing) processing”, etc. By deburring, leveling and polishing the tool, the quality of the tool and the service life are improved.
1. Purpose of tool passivation and polishing:
1. Improve the service life of the tool.
2. Improve the machining efficiency of the machine tool.
3. Reduce the surface roughness of the workpiece.


Second, the main effect of tool passivation:
1. Rounding of the cutting edge: remove the burr on the cutting edge and achieve precise and straight rounding processing.
2. Edge burrs cause tool wear and the surface of the machined workpiece will also become rough.
3. After passivation treatment, the cutting edge becomes very smooth, which greatly reduces chipping and improves the surface finish of the workpiece.


3. Polishing of the cutting groove:
1. The uniform polishing of the tool groove improves the surface quality and the grinding performance.
2. The smoother the groove surface is, the better the chip removal is, and the higher speed cutting can be achieved; at the same time, after the surface quality is improved, the risk of the tool and the processing material being seized is also reduced, and the cutting force can be reduced by 40%. , the cutting is smoother.

Fourth, the tool passivation polishing method:
1. Brush.
2. Sandblasting.
3. Drag polishing machine.
Among them, the brush and drag type are the most widely used.
