Novel abrasive disc for diamond grinding and machining and rapid production method of novel abrasive disc

Abstract

The invention discloses a novel abrasive disc for diamond polishing and processing and a rapid production method thereof, the novel abrasive disc comprises a polishing layer, a bonding layer and a nylon flannelette thread gluing used for being connected with polishing equipment, and the polishing layer is bonded on the nylon flannelette thread gluing through the bonding layer. The outer ring grinding particles and the inner ring grinding particles are arranged on the grinding layer, two structures of different shapes are arranged and matched for use, and the grinding efficiency and the grinding quality are improved; the large-particle diamond grinding material and the resin coating are added into the preparation raw materials of the grinding layer, the strength of the grinding face is improved through the resin coating, the bonding force for connecting the grinding disc particles is enhanced, and therefore the technical effect that the grinding disc particles are not prone to falling off in the using process of high-speed rotation is achieved.

Description

technical field [0001] The invention relates to the related field of diamond grinding tools, in particular to a novel abrasive disc for diamond grinding and a rapid production method thereof. Background technique [0002] Non-metallic materials are more and more widely used in production and life, such as from cement floor to granite, marble, ceramic floor, the wide application of glass in photovoltaic and mobile phone panels, and the emergence of sapphire mobile phone panels. In many fields, the requirements for processing quality are getting higher and higher. However, due to the limitation of materials and environment, it is not suitable to use coolant for cooling during processing. Dry grinding and dry polishing must be used to achieve the required surface processing quality. However, another problem arises. Grinding without cooling liquid will inevitably increase the temperature of the processed surface. Therefore, dry grinding also has high requirements for the high te...

Problems solved by technology

However, another problem arises. Grinding without cooling liquid will inevitably increase the temperature of the processed surface. Therefore, dry grinding requires high temperature resistance of the grinding disc. If the grinding disc has insufficient high temperature resistance During the grinding process, the surface of the workpiece being processed will be scorched and burnt due to the dry grinding disc being unbearable; the discoloration and adhesion of residues on the surface of the grinding disc and the processed workpiece will lead to the inability to continue grinding, grinding and processing the workpiece The adverse consequences of damage and scrapping

[0003] At present, there are diamond dry grinding sheets used for grinding stone, ceramics and other materials, but the shape of the grinding particles of the existing grinding sheets is relatively single, which makes the grinding effect poor. At the same time, the existing grinding particles are made of a single resin raw material. It is made and formed in the form of drying and drying, so that the bonding force of the grinding disc particles is insufficient, the wear resistance is poor, and the service life is short, which leads to easy threshing during grinding processing, which affects the grinding effect, high scrap rate, and grinding The processing and forming steps of the sheet are cumbersome, and it takes a long time to form by baking, which affects production efficiency and increases production costs
