Problems solved by technology

When the high-speed steel integral circular saw blade cuts stainless steel and other profiles, the cutting speed is low, the tool wear is serious, the deformation near the profile incision is large, and the incision is rough. Subsequent processing is required to correct and trim the incision. The production efficiency is low, the cost is high, and the processing quality is difficult to guarantee.
When cutting resin cutting discs, not only the cutting part is severely worn, but in order to obtain a certain strength, the thickness of the cutting discs is mostly 3.2mm or thicker, which wastes the metal material to be cut, and requires sufficient cooling liquid, which is not conducive to environmental protection

Abstract

The invention provides a diamond saw bit used for cutting alloy steel and a preparation process thereof. The diamond saw bit comprises a metal substrate and a diamond cutter head, wherein the diamond cutter head comprises the following components in part by weight: 41-53 parts of alloy powder, 8-12 parts of iron powder, 7-10 parts of nickel powder, 11-18 parts of cobalt powder, 4-6 parts of titanium powder and 12.5-15 parts of diamond, and the alloy powder is prepared from 30-35 parts of copper powder, 3-5 parts of tin powder, 5-8 parts of zinc powder and 3-5 parts of rare earth. The diamond saw bit has the advantages of good heat dissipation effects, good wear resistance, relatively lower cutting temperature, high cutting efficiency and the like.

Description

technical field [0001] The invention relates to a diamond saw blade mainly used for cutting high-strength, high-temperature-resistant alloy steel thin-wall pipes and a preparation process thereof. Background technique [0002] High-strength, high-temperature alloy steel pipes (such as stainless steel pipes) such as cutting austenitic stainless steel, mostly adopt high-speed steel (HSS) integral circular saw blades and resin cutting blades. When the high-speed steel integral circular saw blade cuts stainless steel and other profiles, the cutting speed is low, the tool wear is serious, the deformation near the profile incision is large, and the incision is rough. Subsequent processing is required to correct and trim the incision. The production efficiency is low, the cost is high, and the processing quality is difficult to guarantee. When cutting resin cutting discs, not only the cutting part is severely worn, but in order to obtain a certain strength, the thickness of the cut...
