Problems solved by technology

[0006] However, in some processing environments, especially dry grinding and cutting environments, the metal has strong thermal conductivity, and it is easy to quickly conduct heat to the resin, causing the resin to overheat or even carbonize, thereby reducing the adhesion of the carcass. The joint surface is easy to form a burnt edge, so that the metal particles fall off, causing the tool to be scra

Embodiment 1

[0045]Commercially available ceramic powder and diamond (superhard material) sintered body are pulverized, and the sintered body component is by mass percent, ceramic powder 20%, diamond 80%, and screening obtains irregular irregular ceramic particles containing 60 mesh diamond ( The particle size is 1-3mm). After uniformly mixing the obtained ceramic particles with the phenolic resin, 60-mesh diamond powder and zinc oxide powder constituting the abrasive bond on a mixer, the abrasive containing ceramic particles of the present invention is obtained. The composition of the obtained abrasive material containing ceramic particles is 20% of ceramic particles, 60% of phenolic resin, 10% of diamond and 10% of zinc oxide powder according to mass percentage. The obtained abrasive containing ceramic particles is packed into a metal mold, and the mold is put into a hot press at a temperature of 200°C for 15 minutes, and then the mold is opened to produce a 60# diamond grinding disc. s...

Embodiment 2

[0047] Similar to Example 1, the difference is that the commercially available ceramic powder and diamond (superhard material) sintered body is composed of 99% ceramic powder and 1% diamond by mass percentage. The components of the obtained abrasive material containing ceramic particles are proportioned by mass percentage as 3% of ceramic particles, 60% of phenolic resin, 10% of diamond, and 27% of zinc oxide powder.

Embodiment 3

[0049] Similar to Example 1, the difference is that the commercially available ceramic powder and diamond (superhard material) sintered body consists of 60% ceramic powder and 40% diamond by mass percentage. The components of the obtained abrasive material containing ceramic particles are proportioned by mass percentage as 90% of ceramic particles, 8% of phenolic resin and 2% of diamond.

Abstract

The invention relates to an abrasive, in particular to an abrasive containing ceramic grains, a preparation method and applications of the abrasive. The abrasive comprises ceramic grains and abrasive adhesive, wherein, the ceramic grain comprises ultra-hard material and a ceramic adhesive; the ceramic powder and the ultra-hard material are burned together, crushed and screened to obtain the ceramic grains; subsequently, the ceramic grains are uniformly mixed with the ultra-hard material and metal adhesive or resin adhesive which compose the abrasive adhesive, thus obtaining the abrasive containing the ceramic grains; alternatively, the ceramic powder and the ultra-hard material are sintered together, crushed and screened to obtain the ceramic grains; the ultra-hard material and the metal adhesive or the resin adhesive are uniformly mixed to obtain the abrasive adhesive; and the ceramic grains and the abrasive adhesive are uniformly mixed, thus obtain the abrasive containing the ceramic grains. The abrasive containing ceramic grains can be used for preparing ultra-hard tools which have wider applications and can be used in dry and high-temperature environments, thus overcoming the shortages that the use performance of the tool is affected, the tool has difficulties to remove chips when in use and the sharpness of the tool is reduced, and the like caused by that the tool is easy to generate plastic deformation under high temperature.

Description

technical field [0001] The invention relates to an abrasive material, in particular to a superhard abrasive material containing ceramic particles which can be used to make superhard tools, a preparation method and application thereof. Background technique [0002] Superhard materials include diamond, cubic boron nitride, diamond polycrystal, cubic boron nitride polycrystal, etc. When super-hard materials are used to make super-hard tools, in addition to direct single-piece inlays to form tools, most of them use super-hard materials as raw materials, and combine them with metal, resin, ceramic binders and super-hard materials to form various shapes. superhard tools. Superhard tools can be used to process non-metallic brittle materials such as stone and glass and metal alloy materials. [0003] Most of the existing stone processing fields use diamond tools. Most of these tools are combined with metal, resin, ceramic bond and superhard material, and are manufactured into var...
