When the workpiece material structure, hardness, allowance is not uniform, the tip is the most vulnerable cutting part of the tool. If the tip first contact with the workpiece, most of the impact forc...

(1) Formation reasons In the part near the cutting edge, the tool-chip contact area, due to the great downforce, the chip bottom metal embedded in the front knife surface of the micro uneven peaks ...

When the workpiece material structure, hardness, allowance is not uniform, the large front Angle leads to the cutting edge strength is low, the process system rigidity is insufficient to produce vibra...

Hardness of CBN is higher than ordinary abrasive. High hardness means stronger and sharper cutting power. CBN has high wear resistance, meaning it is more difficult to wear than ordinary abrasive. ...

According to the analysis of the PCD cutting model, the machineed surface is formed by the interaction between the rebound of the workpiece material after extrusion by the edge and the tool back surfa...

The PCD tool material has high hardness, good thermal conductivity and small friction coefficient, which makes the cutting force reduced, the tool wear is slow, the cutting process is more stable, and...

Single crystal diamond tools are almost exclusively used for high-precision finishing, which can ensure extremely high dimensional accuracy. PCD and CVD diamond can be used in many of the same process...

tool tool Damage is relative to wear. In a sense, damage can be considered an abnormal wear and tear. Tool breakage has early and late (processing to a certain time after the damage) two kinds. The...
