Product List

These wheels realize high-precision grinding of iron materials used for automobile parts and the like. They provide the advantages of high performance and stable quality. CBN wheels with an axis are also available.

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.

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 inserts can be attached to cutting tools much like cemented carbide / tungsten carbide inserts. However, compared to carbide inserts, these inserts produce finer finished surfaces and can last up to ten times longer. They can also be made in various shapes and the most appropriate chip material for target work materials can be available.

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.

This wheel is a high-precision assembly consisting of multiple cutters (blades) that simultaneously machines complex form products of quartz, ceramics, ferrites, glass, and carbide alloys.

These chip saws are edged with PCD (polycrystalline diamond) and can produce finer surfaces than cemented carbide / tungsten carbide tools while lasting ten times as long. They are effective for cutting and grooving of architecture materials, wood, aluminum alloys, glass fiber composite materials, rubbers, and plastics.
