Abstract

The invention discloses a grinding body which is mainly prepared by dispersing the following components in parts by weight in a solvent, mixing and curing: 85-95 parts of inorganic micro-powder abrasive; 3-8 parts of cured resin; 2-6 parts of a suspending agent; 0.1 to 1 part of a defoaming agent; and 1-3 parts of an alkoxy compound. The invention further discloses a preparation method of the grinding body, and the grinding disc and the grinding pad embedded with the grinding body. The grinding body can fall off automatically and averagely during grinding, the consumption is quite average, the grinding disc cannot be blocked, workpieces are not prone to being scratched, and due to the fact that the grinding body is embedded into the grinding disc and the grinding pad according to the technical scheme, the grinding body has the advantages that cutting and grinding efficiency is high, the surface quality of the machined workpieces is extremely good, frequent finishing is not needed, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to a grinding body, a preparation method thereof, a grinding disc and a grinding pad embedded with the grinding body. Background technique [0002] The grinding disc or grinding pad of traditional grinding equipment, the abrasive component is usually a combination of a single inorganic micropowder abrasive and a fixed resin, and a layer of grinding body is formed on the active surface by coating. During the grinding process, The grinding body layer also has the technical problems of uneven consumption and easy clogging. Due to the uneven consumption of the grinding body, it will cause the grinding body to easily scratch the workpiece, and the grinding debris will block the grinding disc. For this reason, the grinding disc often needs to be repaired. The service life of the grinding disc is reduced, and because the process is cumbersome and complicated, the production efficiency is ...
