Problems solved by technology

Diamond tools usually include a diamond cutter head and a substrate. The thickness of the substrate determines the thickness of the diamond cutter head. The thicker the substrate, the wider the slit when cutting, the lower the cutting efficiency, the greater the material loss, the worse the economic benefit, and the thinner the substrate. The thinner the cutter head, the higher the cutting efficiency and the lower the material loss; however, the thinning of the substrate will lead to a decrease in the rigidity of the substrate itself, a reduction in the load-bearing capacity, and deflection during cutting, thereby losing the cutting ability

Abstract

The invention relates to a manufacturing method of a hot-pressing double-sided concave inclined dry slice and belongs to the technical field of ultra-hard cutting products. The manufacturing method of the hot-pressing double-sided concave inclined dry slice includes the following steps that firstly, a slice base body comprising a round body and an annular installing end formed in the manner that the outer edge of the round body extends outwards is formed through machining; secondly, the upper surface and the lower surface of the annular installing end are each provided with a diamond tool bit blank body through a cold pressing process; and thirdly, a diamond tool bit is formed through a hot-pressing sintering process, and the pressure of the hot-pressing sintering process ranges from 100 MPa to 150 MPa and the temperature of the hot-pressing sintering process ranges from 830 DEG C to 880 DEG C. By means of the dry slice, the holding force of diamond particles is remarkably improved, the abrasion-resistant performance of the dry slice is good, and the service life is long; and during machining, the energy consumption and losses of machined materials are reduced, and therefore the cutting quality is improved.

Description

technical field [0001] The invention relates to the technical field of superhard cutting products, more specifically, the invention relates to a hot-pressed double-sided concave oblique dry slice used for cutting and trimming non-metallic brittle hard materials such as marble, granite, cement concrete, etc. manufacturing method. Background technique [0002] In today's market, diamond tools have been widely used in the cutting and repairing of hard materials such as marble, granite, concrete, asphalt, ceramics, glass, jewelry and jade; continuously improving cutting efficiency, reducing material loss, and improving the service life of diamond tools are the market common direction. Diamond tools usually include a diamond cutter head and a substrate. The thickness of the substrate determines the thickness of the diamond cutter head. The thicker the substrate, the wider the slit when cutting, the lower the cutting efficiency, the greater the material loss, the worse the econom...
