A kind of edge treatment for improving life in quenched steel processing:

After the PCBN insert is sharpened by the diamond grinding wheel, there is often a certain degree of microscopic gap in the edge, such as a tiny chip, saw, etc. During the cutting process, the microscopic notch of the edge is easily expanded, which will accelerate the wear and damage of the insert. Our edge treatment scheme eliminates the micro-defects of the edge generated in the processing, and after the edge is treated, the insert can be strengthened, and the wear resistance of the insert is also improved, so that the tool life is improved.

A coating process with improved tool life:

Our company independently researched a nano-coating process to improve tool life, PVD coating has a super high hardness, but most of the manufacturer's coatings are too hard and the first cutting at the edge collapses. Our company designed a layer of stress absorption film under a thick high hardness film, which greatly increased the stability of the hard film and increased the tool life by 2 to 5 times, which is a pioneering move in the coating industry. The hard coating of the edge has no micro-collapse, and the surface of the cut product is brighter and meets the requirements of high-precision cutting.
