Diamond cutting bit

Abstract

The invention is concerned with the diamond cutter head that is small cutting resistance and good tartness, includes: the inner edge of the cutter head that connects with the outside of the matrix radial of the diamond saw blade, and the outer edge of the cutter head that is the cutting functionary, sets 1 to three groove on the outer edge of the cutting edge from the radial extending direction of the outer edge to inner edge of the cutter head, the thickness of the cutter head is increase gradually. The wear of the cutter head is equal during the cutting process by the grooves, ensure the tartness of the blade namely improve the cutting efficiency, extends the using life.

Description

technical field [0001] The invention relates to a diamond saw blade, in particular to a diamond cutter head fixed on the radially outer side of a diamond saw blade base body. Background technique [0002] It is known that diamond saw blades are used to cut non-metallic materials, especially stone slabs. It includes a disc-shaped substrate and a number of diamond cutter heads uniformly arranged on the radially outer side of the substrate. There are gullets which extend towards the base portion in a radial direction. Each diamond segment is roughly in the shape of a cuboid, the inner side of which is fixedly connected to the substrate, and the outer side is an arc with the center of the substrate as the center. Referring to Fig. 1, when this kind of diamond cutter head is fixed on the radially outer side of the substrate for cutting operations, assuming that the cutting direction is the direction shown by the arrow in Fig. 1, the cutting edge 2' touches the cutting workpiece ...

AI Technical Summary

Problems solved by technology

Referring to Fig. 1, when this kind of diamond cutter head is fixed on the radially outer side of the substrate for cutting operations, assuming that the cutting direction is the direction shown by the arrow in Fig. 1, the cutting edge 2' touches the cutting workpiece earlier than the cutting edge 1', It bears a lot of force, and the blade 2' wears faster than the blade 1', so after a period of use, the blades at different positions of the cutter head wear unevenly, and this imbalance greatly affects the cutting speed and the diamond saw blade. In addition, due to the resistance of the workpiece on both sides of the cutter head during the cutting process, the stress on the alveolar on the substrate increases, which intensifies the occurrence of unfavorable conditions such as alveolar cracking or cutter head fracture
