Product List

These wheels are used for grinding PCD and PCBN tools, which have higher hardness, higher strength and higher abrasion resistance than carbide tools. Two (non-porous and porous) "high-RESPONSE" bond types are available to meet customer needs for higher precision and higher efficiency.

The highly durable "BJ0" resin bond wheel is useful for flute grinding of high-speed drills and taps. It has low grinding resistance in creep feed grinding of high-speed steel, thus maintaining its high cutting performance.

Diamond mounted V-face wheels are tools mainly used for aspherical surface machining of glass lens molds.
For plastic lens molds, nickel is machined with an ultra-precise single-crystal diamond cutting tool, while ultra-fine binderless cemented carbide is used for glass lens molds.　In addition, demand for SiC molds has been increasing recently.
For the machining of such binderless cemented carbide and SiC lens molds, grinding with a diamond wheel with shaft is used because cutting with a single-crystal diamond cutting tool is unsuitable and inefficient.
We have extensive experience with single-crystal diamond cutting tools for plastic lens molds, and also offer various specifications of diamond mounted wheels for glass lens mold machining.
In addition to V-face shaft wheels, we also offer cylindrical small-diameter shaft wheels for diagonal grinding, free-form grinding, dressing, and sleeve mold machining.

These mono-crystal diamond bites have fine cutting edges made of single-crystal diamonds, which have excellent wear resistance and can make the edges very sharp. By using single-crystal diamond microbites, a cutting edge controlled in micrometers (μm) is transferred to a workpiece, and a fine groove pattern can be formed with high precision and a continuous pitch.
 

[Typical applications of mono-crystal diamond ultrafine cutting tool]

Machining of optical films for FPDs and precision molds for optical elements Micro-pattern forming and planer machining Machining of diffraction gratings Other MEMS and bio-related micro-pattern machining

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 are single-crystal diamond cutting tools for producing smooth mirror surfaces. They are used for photoconductive drums (for cylinder), polygon mirrors (for end face), etc.

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 wheels are used for cutting and grooving cemented carbide / tungsten carbide, cermet, ceramics, glass, ferrites, semiconductors, carbon, and other non-iron metal materials. They realize less bending and a higher quality cutting surface. A resin bond CBN wheel is provided for cutting neodymium magnets.

These high-efficiency cutting wheels are suitable for high-quality cutting of rare earth magnets such as neodymium magnets and iron-based materials. Their high cutting performance improves cutting surface quality and hence work quality.
