Product List

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.

This is a mono-crystal diamond radius cutting tool with a cutting edge waviness of 50 nm or less. It realizes high-precision machining, thus reducing mold production processing requirements. Due to its fine rake and clearance surface, it can elicit better performance of a 3-axis machining device and improve the copying performance of molds. It also realizes high-precision machining by a 2-axis machining device.
 

[Typical applications of highly contoured mono-crystal diamond cutting tools]

Camera lens molds for smartphones, PC and tablets, pickup lens molds, ultra-precision machining, infrared lenses, various spherical and aspherical lenses.

This high quality mono-crystal diamond ball end mill can be used at speeds up to 100,000 revolutions per minute (RPM). It has a fine cutting edge and a low axis deviation. W.A.90 products will be available.

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 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.
