Method for producing diamond tool for grinding concrete floor

Abstract

The invention discloses a method for producing a diamond tool for grinding a concrete floor, which comprises the following steps: proportional irregular glomerocryst diamond and man-made diamond are uniformly distributed on the surface of a tire casing; a gap between the diamond is filled with metallic bond, and according to the ratio by weight, the metallic bond comprises 40 to 70 percent of cobaltco, 10 to 20 percent of copper, 15 to 20 percent of tungsten carbide, 5 to 10 percent of stannum and 0.5 to 3 percent of trace element; the operation of cold press molding is carried out, sections formed by the cold press molding are delivered to a vacuum hot press sintering furnace to be sintered, and the temperature is kept from 850 DEG C to 900 DEG C and the pressure from 10 to 15 tons; and the sintered sections are welded on a metal base body. The diamond tool produced by the method not only can increase the grinding efficiency and maintain the stable performance, but also can greatly prolong the service life.

Description

technical field

[0001] The invention relates to a method for manufacturing a diamond tool, in particular to a method for manufacturing a diamond tool for grinding concrete floors. Background technique

[0002] In the prior art, tools for grinding various hard non-metallic materials such as stone, concrete molding surfaces or ceramics generally use diamond tools, which utilizes the characteristics of high hardness of diamond. At present, natural large-grain diamonds (such as 6#, 16#) and artificial diamonds (such as 20#-200#) are used for the smoothing of large-area rough concrete surfaces. Because only natural diamonds have such large particles, and only large particle diamonds can work efficiently enough to meet the rough grinding requirements of concrete ground engineering. Fine grinding is with synthetic diamonds. However, both natural diamond and artificial diamond are single crystal diamonds, so their grinding tools have the following disadvantages:
