Perhaps many friends don't know that grinding is an important link in the process of machining. In the manufacturing industry of industrialized countries, grinding costs account for about 20% - 25% of the processing costs. So why is that? As we all know, grinding can obtain the required product shape and can process high hardness materials. Through grinding, we can obtain the surface of the smooth parts and the precise tolerance. However, the superhard material products are an important part of grinding materials. The superhard material products are made of diamond or CBN particles as cutting and grinding materials, with the help of binder or other auxiliary materials, and have certain shape, size, performance and use.

 

diamond

 

Diamond is generally used to make resin bonded or ceramic bonded abrasives, used to process cemented carbide, nonmetal and abrasive. Metal bonded products are the first diamond products that have been successfully developed and applied. At present, they have the largest variety and consumption. The most widely used category. Resin bonded products: mainly used for grinding the outer circle of carbide cutting tools, measuring tools, roller drilling ball teeth, the plane of mold and slotting, etc. Ceramic bond products: can well meet the needs of high precision grinding and efficient grinding of difficult to process materials and general materials, and is suitable for application in CNC grinding machines and automatic production lines, such as flat, cup-shaped and bowl shaped grinding wheels.

 

grinding wheel

 

The grinding wheel is made of abrasives and binder resins. The abrasives are added with binders, and the porous bodies are made by pressing, drying and roasting. The grinding wheel is one of the most widely used grinding tools. It can be used for high-speed rotation, rough grinding, semi-fine grinding, fine grinding, slotting and cutting of the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces. Due to different abrasives, binders and manufacturing processes, the characteristics of grinding wheels vary greatly, which has an important impact on the grinding quality, productivity and economy. According to the structure of the machine tool and the needs of grinding, the grinding wheel is made into various shapes and sizes. The outer diameter of the grinding wheel should be selected as large as possible to improve the peripheral speed of the grinding wheel and improve the grinding productivity and surface roughness. Under the condition that the rigidity and power of the machine tool are allowed, the wider grinding wheel can also improve the productivity and reduce the roughness. However, when grinding materials with high thermal sensitivity, the width of the grinding wheel should be appropriately reduced to avoid the burn and crack on the workpiece surface. Zhengzhou Hongtuo superhard material products provide grinding solutions for ceramic products, provide grinding wheels of various specifications, and process metal ceramic products with good surface quality, no burn, and strong cutting force. At the same time, because of its high cost performance and excellent processing ability, it can replace similar foreign products.
