Embodiment Construction

[0015] The diamond cloth abrasive tool of the present invention is formed by hot pressing after mixing soft carcass material and irregularly shaped diamonds of 170 mesh to 400 mesh into a uniform mixture, wherein the amount of diamond depends on its particle size. Generally, when the particle size is 170 mesh to 400 mesh, the concentration is about 15-20%. In this embodiment, the concentration of diamond is 15%. The soft carcass material includes the following components by weight: 13% of cobalt-iron alloy powder, 80% of bronze powder, 4% of zinc powder and 3% of graphite powder.

[0016] The production method of diamond cloth abrasive tool of the present invention, realizes by following steps:

[0017] 1. Prepare the soft carcass material according to the weight ratio of 13% cobalt-iron alloy, 80% bronze powder, 4% zinc powder and 3% graphite, process the cobalt-iron alloy, bronze powder, zinc powder and graphite into powder and mix evenly , the mixing time is 2 to 4 hours; ...

Abstract

A cloth-based grinding tool with very long service life and high self-sharpening performance is prepared from soft substrate and fine or superfine diamond particles with irregular shape through proportional mixing and hot pressing. Said soft substrate contains proportionally Co-Fe alloy, bronze powder, Zn powder and filler.

Description

technical field [0001] The invention relates to a diamond cloth abrasive tool and a production method thereof. The abrasive tool is used for processing granite, marble, concrete, tiles, glass-ceramics and the like. Background technique [0002] Traditional abrasive tools used for assembly line processing are made of magnesite as a binder and silicon carbide (SiC) abrasive grains are added. It is characterized by poor sharpness, low processing efficiency, and short life. In addition to the above shortcomings, This kind of grinding tool also produces a large amount of waste pulp during use, which has obvious pollution to the environment. At present, in developed countries, the rough processing of stone materials has been gradually reduced, and this part of the work has been transferred to undeveloped countries. Even in enterprises that are still producing, they are gradually using abrasives made of metal as a bond and diamond as abrasive grains. Compared with traditional abra...
