It is a composite oxide of alumina and zirconia. This abrasive is grayish white, with high toughness, high strength and good wear resistance. In the rough grinding, raw grinding and heavy load grinding of steel, it shows the characteristics of high grinding efficiency, good roughness, not easy to burn the workpiece, and the surface of the grinding wheel is not easy to block. It is suitable for heavy load grinding, heat-resistant alloy steel, Cobalt alloy and austenitic stainless steel grinding.

In order to give full play to the role of diamond, it is necessary to try to increase the holding force of the bonding agent on the diamond and improve the bonding strength of the grinding wheel. The high-temperature hot-pressing superhard grinding wheel grinding wheel invented by Zhengzhou Jinxi Abrasives Research can overcome the shortcomings of brazed grinding wheel, can realize chemical metallurgical bonding between diamond, bonding agent and metal matrix, and has high bonding strength. Only by maintaining the thickness of the bonding layer at 20% ~ 30% of the height of the abrasive grains can the abrasive grains be firmly held under high load and high speed grinding, so that the height of the hot-pressing grinding wheel abrasive grains can reach 70% ~ 80%, therefore, the chip space is increased, the grinding wheel is not easy to be blocked, and the abrasive is more fully utilized.

The material is S55C, which belongs to high carbon steel and has high carbon content. It has the advantages of high wear resistance, easy post-treatment and uniform structure. It is most often treated by surface quenching and hardening. The strength of high carbon steel after heat treatment is improved and becomes difficult to cut. Therefore, when the abrasive strength is not enough or the crushing property is not enough, it cannot exert good cutting force by itself in the grinding process. In addition, forming grinding has a large load on the grinding wheel, it will produce grinding abnormal sound, temperature increase, grinding wheel surface will soon be uneven and other problems, more serious may cause the workpiece burn.

Abstract Since the first quarter, all enterprises have been at full capacity, setting off an upsurge of grasping production, catching orders and expanding production capacity. During the visit, it was found that the machinery in the factory area was roaring, the production line was running at full capacity, and the workers were busy working. It's...

During the visit, it was found that the machinery in the factory area was roaring, the production line was running at full capacity, and the workers were busy working. In the production workshop, the workers are carefully batching and mixing the products. The staff of the molding workshop are working hard to make molding grinding wheels. Each workshop cooperates with each other to make a large number of orders to be sold all over the country.
