Diamond saw blade and production process thereof

Abstract

The invention discloses a diamond saw blade. The diamond saw blade comprises a lower substrate, a lower silencing layer, a middle substrate, an upper silencing layer and an upper substrate, wherein a circle of large silencing round holes are formed in the lower silencing layer at the position, one third away from the outer edge of the lower silencing layer; silencing seams are also formed in the lower silencing layer, corresponding to the large silencing round holes; a lower spot welding hole is also formed between two adjacent large silencing round holes; a plurality of silencing arc-shaped trunkings are formed in the upper silencing layer and at the position, one third away from the outer edge of the upper silencing layer; inner silencing arc-shaped trunkings are also correspondingly formed in the inner sides of the silencing arc-shaped trunkings respectively; inner silencing seams are formed between the corresponding silencing arc-shaped trunking and the corresponding inner silencing arc-shaped trunking; and an upper spot welding hole is formed between two adjacent silencing arc-shaped trunkings. The diamond saw blade is good in noise reduction effect, high in cutting accuracy, long in service life and ideal in control effect on key indexes including planeness, end jump and stress value.

Description

technical field [0001] The invention belongs to the technical field of cutting, and in particular relates to a diamond saw blade, especially a diamond saw blade with low noise and sound-absorbing function. Background technique [0002] The traditional diamond saw blade noise reduction method generally adopts cutting sound-absorbing seams on the saw blade, punching holes and filling metal materials or adding flexible gaskets to achieve the effect of sound-absorbing and noise-reducing effects. Although it can effectively reduce part of the noise to a certain extent, the effect is It is not obvious, and it will bring some unstable factors in cutting such as flatness, end jump, stress deformation, etc. Contents of the invention [0003] In order to solve the above problems, the present invention provides a diamond saw blade with noise reduction function, the saw blade has good noise reduction effect, long service life and stable cutting. [0004] In order to achieve the above...
