How to improve the sharpness of the blade tip?

  • Author:Dora Zhang
  • Release on:2022-07-21
During cutting, the blade will get stuck when cutting because of insufficient sharpness.Diamond segment for granite stone processing,allows good sharpness and ideal chip removal.


This situation is mainly reflected in the situation that when maintaining a certain mechanical speed, the cutting speed is slow and the cutting speed is normal. Increasing the speed, the diamond cutter head consumption is too fast, and the cutting efficiency cannot be increased.Cutting segments for stone slab cutting adding water can prolong the service life of your saw blade head and reduce the cost.


Generally, there are four solutions to this situation, which can significantly improve the sharpness of the cutter head:


1. Slightly reduce the content of cobalt and tungsten in the diamond bond. The advantage of this is to reduce the hardness of the metal bond and better expose the diamond powder. The disadvantage is that this practice will reduce the service life of the cutter head and is likely to cause instability of the cutter head.


2. Increasing the concentration of diamond is obviously reflected in the insufficient exposure of diamond. In order to increase the exposure of diamond, increasing the concentration of diamond can properly solve the problem. It is very important to keep the diamond of the cutter head highly exposed at all times, but this improvement method will increase the consumption of diamond powder. In short, it will increase the material cost of the cutter head. And the concentration of diamond should not be increased too high. Too high concentration will reduce the holding force of the metal bond of the cutter head, resulting in diamond falling off.

Professional supplier to diamond segment,the segment with unique TT design allows the removal of ideal debris, better cooling, good sharpness and cutting efficiency.


3. The layered cutter head is adopted. By increasing the non working layer and increasing the cutting pressure, this process has also been recognized and applied by the most people. Adding an iron sheet or alloy powder layer to the non working layer can not only form a waterway, facilitate chip removal, but also allow the cutter head to be cooled more quickly, increase the cutting efficiency and ensure the cutting life.


4. Increasing the particle size and concentration of diamond and further increasing the strength of matrix bond are mostly used in foreign diamond cutting heads. Increasing the particle size of diamond can increase the exposure of diamond, and increasing the matrix bond is better in line with the particle size of large grain diamond. If you only increase the grain size of diamond, there is likely to be insufficient holding force, resulting in diamond falling off.
