How to improve the surface finish of the tool holder?

July 31, 2019

Product Description: The name of a process before coating after finishing is not uniform at home and abroad. It is called "edge passivation", "edge strengthening", "edge honing", "edge preparation" or "ER (Edge Radiusing) treatment". By deburring, leveling and polishing the cutter, the quality of the cutter can be improved and the service life can be prolonged.
1. The purpose of tool passivation and polishing:
1. Improve the service life of cutting tools.
2. Improve the efficiency of machine tools.
3. Reduce the surface roughness of the workpiece.

2. Main effects of tool passivation:
1. Rounding of the edge: Removing the burr of the edge to achieve precise inverted circle processing.
2. Blade burrs cause tool wear and rough surface of workpiece.

3. After passivation treatment, the edge becomes very smooth, which greatly reduces the avalanche and improves the surface finish of the workpiece.

3. Polishing of the cutting groove:
1. Uniform polishing of tool grooves can improve surface quality and flapping performance.
2. The smoother the groove surface is, the better the chip removal will be, and the higher the cutting speed will be. At the same time, the higher the surface quality is, the less dangerous the tool and the processing material will bite, and the cutting force will be reduced by 40% and the cutting will be smoother.

4. Ways of tool passivation and polishing:
1. Brush.
2. Sandblasting.
3. Drag polishing machine.
Among them, brush and drag are the most widely used.
