About the effect of hardness on the work of the cutting piece

customized metal cutting disc

In our work, the cutting pieces are divided into soft, medium soft, hard and super hard. Each is divided into several levels. The hard cutting piece is not easy to fall off, and the ground metal scraps are easy to stick to the customized metal cutting disc, which causes the surface of the workpiece to burn; the soft cutting piece is easy to fall off and does not burn the workpiece, but the cutting piece consumes faster.

The soft cutting piece we talked about is not to say that the crystal grain of the cutting piece is soft, but that the bonding strength of the sand grain is soft and it is easy to fall off, so that when the sand grain is slightly sharpened, it will fall off, and the new one will fall off. The sharp sand continues to be ground, so that the sharpness of the abrasive is maintained, and the hard material is also softened.
If we use hard-to-hard methods, there will be two strong encounters, and each other will not give way to each other. There will be serious slippage between the cutting piece and the material. If no one can do anything, it will not move.
It is not necessary to use hard cutting materials to soften the material. It is not too difficult to use soft cutting pieces to grind soft materials. The soft material and hard material have a larger friction coefficient, and the sand on the surface of the soft cutting piece is It is easier to fall off, and when the sand is sharp, it will fall off. If the sand is not fully utilized, the cutting piece will soon be rebuilt. Even if the cutting piece is worn faster than the soft material, there is still a phenomenon of grinding, and then grinding The efficiency is greatly reduced, so it is necessary to use a hard-cut piece with strong bonding.
