Diamond Grinding Tools for Glass Ceramics

Why Use Diamond Coated Tools

Crystalline diamond coating can increase tool life 10 to 20 times (or more) over uncoated tools with faster material removal, more reliable unattended high precision machining and reduced use of coolants.

Improved Cutting Tool Performance

Crystalline diamond coating has all of the properties of natural diamond including extremely high mechanical hardness, strength, and thermal conductivity, resistance to chemical corrosion and a very low coefficient of friction. All of these properties contribute to the capability of diamond to improve tool performance by decreasing the number of chipped units, increasing the number of units per tool yield and decreasing overall cycle times per unit.    

Crystalline Diamond (CVD) vs Diamond-like Coating (DLC)

Crystalline diamond has all of the properties of natural diamond including extremely high hardness strength, thermal conductivity and resistance to chemical corrosion in addition to a low coefficient of friction. Diamond like coatings (DLC's) consist of amorphous carbon with about one-half the hardness of crystalline diamond and provide much less tool life in cutting hard abrasive materials.
