Vitrified Bond Diamond Grinding Wheel Usage

- 2021-Sep-26-

With the development of science and technology, the continuous growth of new materials, and the continuous development of high-quality, high-precision, high-efficiency, and automation in mechanical processing, the application range of vitrified bond diamond SDC grinding wheels is becoming wider and wider, and the dosage is increasing.

Ceramic bond diamond grinding wheels are mainly used in wafers (semiconductor wafers and solar wafers), diamond composite wafers, polycrystalline diamond, PCD cutting tools, cubic boron nitride, tungsten steel (hard alloy), new engineering structural ceramics, gems , Crystal, rare earth materials (magnetic materials) and other high-hard and brittle materials, and have achieved good economic benefits.

Diamond cutting tools are mainly concentrated in PCD composite sheets, chemical vapor deposition (CVD) coated tools and single crystal diamond tools. Choosing reasonable process parameters, the grinding efficiency of ceramic bond diamond grinding wheels for single crystal diamond is higher than that of metal bond grinding wheels, the abrasion ratio is very small, and the processing cost is low. Therefore, the use of ceramic bond grinding wheels for grinding single crystal diamonds can greatly improve Breaking grinding efficiency. In the aspect of grinding PCD tools, because the resin bond is soft, it is easy to deform during grinding, and cannot effectively grind PCD tools; the metal bond has too strong ability to bond the abrasive particles, which makes the abrasive tools have poor self-sharpening. Low efficiency, and the metal bond grinding wheel will cause the most serious damage to the edge of the PCD tool; comprehensive grinding efficiency, grinding tool durability and the processing quality of the workpiece surface, the ceramic bond diamond grinding wheel is the most suitable choice for grinding PCD tools .

  Fine-grained vitrified bond diamond grinding wheels are used for precision dimensional processing of chromium-quenched steel bearing rollers.
  Vitrified bond diamond grinding wheels are used for precision machining of crankshafts of automobiles, tractors, and gear necks of hydraulic pumps.


  The vitrified bond diamond grinding wheel with good toughness is used for rough grinding and fine grinding of the fluorescent screen of TV kinescope. The use of ceramic bond diamond grinding wheels to process high-performance silicon wafers for integrated circuits has high processing accuracy and low processing roughness, and there is no metal ion pollution on the silicon wafers after grinding, and the qualified rate of processed products is high.
