Vitrified bond diamond grinding wheels possess pretty high abrasive resistance, especially in polishing hard and brittle workpiece. It has many advantages like small grinding force, low operating temperature, high grinding precision, excellent workpiece's surface grinding, etc. Therefore, vitrified bond diamond grinding wheel will express the better advantages in the future. It is recognized as a high performance grinding wheel with the higher speed, higher efficiency, higher precision, lower abrading cost and lower pollution. Based on these superiorities, vitrified bond diamond bruting wheel is widely used in wafer, PDC, PDC, diamond cutter, CBN, cemented carbide, new engineering structural ceramic, diamond, jewel, crystal, rare earth materials and another hard-brittle materials' machining operation.
