Speed, high efficiency, high precision grinding CBN grinding technology has become the mainstream of development

Speed, high efficiency, high precision grinding CBN grinding technology has become the mainstream of development. The use of ceramic CBN wheel speeds generally reach 80-120m / s ,150-200 m / s wheel cubic boron nitride entered the practical stage. Its manufacturing technology to become an important part of CBN grinding technology is directly related to the effects of grinding wheel as well as equipment and personal safety. Strength is the kind of grinding wheel manufacturing abrasive wheels first be concerned about one of the most important technical parameters.
Grinding wheel rotating at high speed, and the stress generated when the strength of their own studies using two key security. For speed 80 ~ 120m / s high-speed grinding wheel in terms of high-speed rotation when the overall strength is Synthetic diamond important. Three parts should examine its strength: a base body, the adhesive layer and the abrasive layer. Their strength is generated when the high speed rotation is greater than the stress, the wheel will not break, the abrasive layer is not peeled off from the substrate.
