The plane density of diamond on the working layer of the matrix of diamond tool head is related to the strength of the matrix of the tool head to encapsulate diamond, the size and concentration of diamond selected by the tool head. The higher the concentration of diamond selected by the diamond cutter head, the higher the uniform density of diamond on the working surface of the matrix of the cutter head, the higher the wear resistance of the diamond cutter head, and the longer the service life of the cutter head. The higher the longitudinal density of diamond in the working layer of diamond matrix, the more layers of diamond in the working layer of diamond matrix, the more layers of diamond in the working layer of matrix, and the longer the service life of diamond tool head. The diamond longitudinal density of the working layer on the matrix of the diamond tool head is related to the diamond particle size and concentration selected by the tool head. The higher the concentration of diamond, the higher the longitudinal density of diamond in the working layer of the diamond tool head, the more layers of diamond in the matrix of the tool head; the finer the size of diamond particles selected by the diamond tool head, the more layers of diamond in the matrix, and the higher the wear resistance of the diamond tool head.

The non-sharp diamond saw blades can be roughly divided into two situations:

1. Sharpness is not good, life (square) is also possible. The poor sharpness of the tool tip is as follows: the current of the main motor is added, the cutting speed is slow, and even the chip runs, screams and so on. The reasons why the sharpness is not good are as follows: the matrix does not match the stone material; the diamond concentration is too high; the amount of fine-grained diamond is too much; the diamond strength is too poor; the diamond matrix density is too high; the knife head width is too large; the power supply voltage is too low; the cutting power is too small; the style of the saw blade base is not good or uneven and there is swing; the cutting machine skin has more than one. Loose; the cut stone is not fixed firmly; the coolant is too thick.
