2. Why is it necessary to passivate the tools?
The cutting edge of a tool, after being sharpened by a regular grinding wheel or a diamond grinding wheel, exhibits microscopic gaps (i.e. micro-scales and saw edges) to varying degrees. During the cutting process, the micro-notch on the edge of the tool can easily expand, thereby accelerating tool wear and damage.
4. The main effects of tool passivation
Evenly polish the tool grooves to improve surface quality and cutting performance.
The flatter and smoother the groove surface, the better the chip evacuation, allowing for a faster cutting speed. high.材料咬死的危险性。并可减少40%的切削力，切削更流畅。
Coating polishing
Eliminate protruding droplets produced after tool coating, improve surface finish and increase lubricating oil adsorption.
The coated surface of the tool will produce tiny protruding droplets, which will increase the surface roughness, making the tool likely to generate greater friction heat during the cutting process and reduce the cutting speed. After passivation polishing, the droplets are removed, leaving many small holes, which can absorb more cutting fluid during processing, greatly reducing the heat generated during cutting and significantly increasing the cutting speed.
