Product List

This is a single-crystal diamond forming cutting tool manufactured using our forming and polishing technology. It realizes forming mirror machining for high-precision production of complex shapes consisting of plastics or soft metals.

We have over 80 years of experience in manufacturing single-crystal diamond bites for cutting processes and have supplied tools for precision machining applications periodically.
By grinding Mono Crystal Diamond (MCD), the hardest material on earth, to a sharp cutting edge, mirror-finish machining is possible in cutting that cannot be obtained with ordinary cemented carbide or PCD (polycrystalline diamond) bites.
The extremely sharp cutting edge can be applied to soft and viscous gold and copper alloys that would be scuffed or crushed by ordinary cutting bites, and a good cutting surface can be obtained.
When cutting acrylic resin, a transparent cutting surface can be obtained without the need for polishing.

We custom-design the optimum specifications to meet your machining requirements and tool geometry. Various insert tip types are also available.

These cutting tools are used for precision machining of mass production parts. The PCD (polycrystalline diamond) tool is used for machining ceramics, plastics, and non-ferrous metals while the PCBN (polycrystalline CBN) tool is used for high-hardness alloy tool steels and difficult-to-cut nickel alloys. These tools possess finer cutting
surfaces than other cemented carbide / tungsten carbide tools and can last up to ten times longer.

These tools are widely used for the precision machining of plastics, aluminum alloys, carbon materials, and ceramics. They can also be used as wood router bits. The tools produce fine finished surfaces that cemented carbide / tungsten carbide tools cannot match, offer high abrasion resistance, and can last up to ten times longer than cemented / tungsten carbide tools.

These wheels can be used to drill clean holes or expand existing holes in hard brittle materials such as cover glasses with a strengthened layer. For thin glasses, machining efficiency can be improved by simultaneously drilling a number of glass plates arranged in a stack.
