How to improve the surface finish of toolholder?

2020-10-28

Product Description: the name of a process after finish grinding and before coating of cutting tools is not unified, such as "edge passivation", "edge strengthening", "edge honing", "edge preparation" or "Er (edge radiating) treatment". Through deburring, leveling and polishing, the quality and service life of the tool can be improved.

1. Purpose of tool passivation and polishing:

1. Improve the service life of cutting tools.

2. Improve the machining efficiency of the machine tool.

3. Reduce the surface roughness of workpiece.


2. The main effects of tool passivation are as follows

1. Edge rounding: remove the edge burr to achieve accurate rounding.

2. The burr of cutting edge will cause tool wear and the surface of workpiece will become rough.

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


3. Polishing treatment for row cutting groove:

1. Polish the tool groove evenly to improve the surface quality and tapping performance.

2. The smoother the groove surface is, the better the chip removal will be, and the higher cutting speed can be achieved; at the same time, with the improvement of surface quality, the danger of tool and processing material seizing can be reduced, and the cutting force can be reduced by 40%, making the cutting more smooth.


4. Tool passivation and polishing methods:

1. Brush.

2. Sandblasting.

3. Drag polishing machine.

Among them, brush and drag are the most widely used
