Superhard material cutting tool and preparation method thereof

Abstract

The invention relates to a superhard material cutting tool and a preparation method thereof, which belongs to the technical field of superhard material. The superhard material cutting tool comprises a steel matrix and a cutting tool bit. The cutting tool bit consists of a polycrystalline diamond compact (1) and a diamond tool bit (2); 1 to 12 inclined cylindrical tanks used for welding the diamond compact are distributed on the outer circle surface of the steel matrix, and the center line of the inclined cylindrical tank forms a cutting angle with the cutting face; the diamond tool bit is welded on the surface of the steel matrix. The polycrystalline diamond compact is combined by PCD and cemented carbide matrix and is sintered from the mixture of diamond and the metal powder after being compacted; the structure thereof is in the shape of cylinder, ladder or squareness; the fringe area of the clad compact is the cutting blade. The superhard material cutting tool solves the materials hard to be processed in the cutting field, and ensures the surface of the machined part free of burr, nick, spray and chatter mark; the cutting and grinding combination not only improves the cutting speed, but also ensures the cutting quality.

Description

technical field [0001] The invention belongs to the technical field of superhard materials, and in particular relates to a cutting tool for superhard materials and a method for removing floor paint by using the tool. Background technique [0002] With the development of material technology and manufacturing technology, various high-performance new materials are constantly emerging, which requires cutting tools to have high hardness, thermal stability, chemical inertness and appropriate toughness, thus bringing great challenges to traditional diamond tools . [0003] 200820123065.5 discloses a clamping diamond grinding disc. The grinding disc is inlaid on the base of the grinding disc through the dovetail wedge of the grinding head. The grinding head and the base of the grinding disc will be automatically locked with the grinding rotation of the grinding disc. There are deep trapezoidal grooves for easy chip removal and cooling. The grinding disc cutter head adopts powder m...
