Because the characteristics of the diamond , making it to the performance of ceramic binders have special requirements , and therefore the current domestic vitrified diamond grinding tools have not been widely used. Mainly for the domestic diamond  abrasive cloth belt  binder resin and metal , vitrified bond amount is also small.
The main reason is : 1 ] due to the production of diamond abrasive low temperature bonding agent , in order to reduce the refractoriness , combined with the introduction of a large number of basic materials agents , so the resulting low temperature ceramic binder , its performance ( low refractoriness , low thermal expansion coefficient , strength, etc. ) is difficult to control ; [ 2 ] during manufacturing, since the inert superhard material , the bonding agent bonding the abrasive grains and the wetting ability, the binding agent reduces the bonding strength of the abrasive grains , grinding when grinding tools , abrasive falling fast , wear big ; [ 3 ] in the grinding process , due to the brittleness of ceramics , abrasives in the use of impact resistance , fatigue resistance are poor, easy to use embrittlement phenomena occur , thus affecting the characteristics of abrasive grinding and poor thermal conductivity of ceramic grinding area of high local temperature , so that heat loss is easy superabrasive grains also affect abrasive grinding characteristics . This directly affects the vitrified bond diamond abrasive used.

Accurately measure the finished recipe abrasive cloth belt research, design, development plays a decisive role, but artificial test data to calculate complex and cumbersome and error-prone, to make abrasive formula becomes simple and accurate measurement, easy one article on computer-aided measurement ordinary resin abrasive finished formulations preliminary exploration. Abrasive formula is based on the manufacturing process, is the key to the production of abrasives. Abrasive formula prescribed ratio of abrasives, binders, fillers, coloring agents of raw materials, feeding unit weight, molding density and other parameters, the decision abrasive performance. Unknown to the finished abrasive formulations were determined formula, mainly for the development and design of products, developed with its own characteristics abrasive products. Determination recipe can be used for abrasive waste analysis, waste generated guide to find the causes and solutions, to create a product to meet user requirements.
