Natural diamond tools


Using the characteristics of diamonds to support micro and ultra-precision machining


Natural diamond cutting tools maximize the potential of diamond, which is a premier material for tool production. Diamond has outstanding hardness, strength, and chemical stability (at temperatures of 600 K or less) and a friction coefficient of 0.1 or less. These properties result in extremely high accuracy compared to cutting tools made from other materials, and diamond is used to improve the accuracy of work pieces used in micro and ultra-precision machining.
