Case 1——Machining PCBN Chamfers with Ceramic Diamond Grinding Wheels
What is the edge treatment of PCBN blade？
The cutting edge of the tool refers to the junction of the rake and flank surfaces of the insert where the workpiece material separates to form chips and machined surfaces.
Tool edge treatment is to improve the quality of the tool and increase the service life of the tool by chamfering, passivating, flattening and polishing the edge after the blade is finely ground.
Why edge treatment?
After the PCBN blade is sharpened by the diamond grinding wheel, the cutting edge often has a certain degree of microscopic gaps, such as micro chipping, sawing, etc. During the cutting process, the microscopic notch on the cutting edge of the tool is easy to expand, which will accelerate the wear and damage of the tool. In order to eliminate the microscopic defects of the edge during processing, edge treatment is required.
After the edge treatment of the PCBN blade, the blade edge can be strengthened, and the wear resistance of the tool can also be improved, thereby prolonging the tool life.
