Diamond chamfering polishing wheel for glass and preparation method thereof

Abstract

The invention relates to a diamond chamfering polishing wheel for glass and a preparation method thereof. The diamond chamfering polishing wheel for glass comprises a base body and an abrasive layer, wherein the abrasive is prepared from the raw materials in percent by volume: 10% to 15% of diamond of more than 800 meshes, 10% to 15% of silicon carbide of more than 600 meshes, 55% to 65% of polyimide resin powder of more than 500 meshes, 5% to 10% of copper powder of 325 meshes and 5% to 10% of silicon carbide of more than 1000 meshes. The abrasive layer is prepared from the raw materials in percent by volume: 10% of diamond of 800 meshes, 15% of silicon carbide of 600 meshes, 60% of polyimide resin powder of more than 500 meshes, 10% of copper powder of 325 meshes and 5% of silicon carbide of more than 1000 meshes. The diamond chamfering polishing wheel has the characteristics of simple and reasonable structure, flexible operation, one-step accomplishment of chamfering and polishing,low manufacturing cost and long service life.

Description

Technical field [0001] The invention relates to a polishing wheel, in particular to a diamond chamfering polishing wheel for glass and a preparation method thereof. Background technique [0002] Currently, 3-6mm thick glass is used in household appliances. After cutting out a large batch of glass sheets of the same specifications, the sharp corners must be removed and the bright chamfered surface should be provided to facilitate further water-coating of metal film on the rear surface. As bright as a silver mirror, it is used for decorative panels of home appliances. It is beautiful and eye-catching. Other chamfering polishing wheels currently in use, such as 10S, BK, BD chamfering polishing wheels and stone wheels, some have too shallow chamfering depth, too slow chamfering line speed, and some have rough chamfering in one step, such as insufficient brightness and large Most chamfers have a short service life and a low overall performance and price ratio.

AI Technical Summary

Problems solved by technology

Other chamfering polishing wheels currently used, such as 10S, BK, BD chamfering polishing wheels and stone wheels, some chamfering depths are too shallow, the line speed of chamfering is too slow, and some primary chamfering is rough, such as insufficient brightness, large The service life of most chamfers is short, and the comprehensive performance and price ratio are low

Chinese Patent Document No. CN101214637A disclosed a glass edging wheel on July 9, 2008, which uses white corundum powder of more than 500 meshes, epoxy resin and phenolic resin in combination with cold pressing and then oven heating. This product is polished Good performance, but the depth of the chamfer is too shallow, the linear speed of the chamfer is too slow, the large grinding resistance causes the motor current to be large, the service life is short, and the time to change the grinding wheel is long.
