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.

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] At present, 3~6mm thick glass is used in household appliances. After cutting out a large number of glass sheets of the same specification, the sharp corners should be discarded, and there is a bright chamfered surface, which is convenient for further water plating on the back surface of the metal film. Bright as a silver mirror, decorative panels used in home appliances, beautiful and generous, attracting attention. Other chamfering polishing wheels currently in use, such as 10S, BK, BD chamfering polishing wheels and stone wheels, some of the chamfer depth is too shallow, the line speed of the chamfer is too slow, and some of the chamfering is rough, such as insufficient brightness and large Most chamfers have short service life and low overall performance and price ratio.
