Vitrified CBN internal wheel for bearing bore

Resin bond Diamond & CBN grinding wheels are the most commonly used SuperAbrasive product currently consumed. Resin bond product, as the names describes, is a combination of resins and fillers pressed under heat and pressure that are easily dressed to straight, angle forms, , and special radius forms. So, which grinding wheel would be ideal to complete your desired results? Well, that depends on what you are trying to accomplish…

PCD tools grinding is a progress of diamond grind diamond, grinding force is big, grinding wheel wears quickly and the temperature of grinding area is high. In order to avoid the very high heat influence the PCD performance, we need to use grinding fluid to lower the temperature of grinding area, also wash and clean the grinding wheel at the same time, to keep grinding wheel sharp.

The hardness of the grinding wheel refers to the ease with which the superhard abrasive falls off the grinding wheel. The harder the abrasive particles fall off, the higher the hardness of the grinding wheel.In general, the more the combined dose, the stronger the abrasive is held, the more difficult the abrasive particles fall off, and the higher the hardness of the grinding wheel. The grinding wheel has a bad cutting edge during grinding, which is prone to grinding.The life of the diamond grinding wheel will increase, but the surface of the composite sheet is prone to chipping. It is necessary to properly grind the grinding wheel to avoid grinding cause waste.

The brazing technology can realize the interfacial chemical metallurgical bonding of diamond, binder (brazing alloy material) and metal matrix with high bonding strength. Due to the high bonding strength at the interface, only a very thin binder thickness is enough to firmly hold the abrasive particles, and the exposed height can reach 70% ~ 80%, make the use of abrasive more fully, greatly improve the tool life and processing efficiency.

Workpiece Materials: grinding tungsten carbide cutting tools, ceramic , magnetic materials, silicon , glass , quartz and thermal spraying alloy ,etc

GrindTec, the international trade fair for grinding technology, opens its doors to visitors from 10-13. November , 2020 in Augsburg, Germany. We would be delighted to welcome you at Booth 2135 in Hall 2. More SuperHard will be presenting products and solutions for the grinding processes
