Product List

This is a small-diameter drill using PCD/polycrystalline diamond for the cutting edge, and is suitable for continuous hole drilling in silicon. The spiral grooves provide good chip evacuation and reduce the frequency of step machining.

Diamond metal bond wheels with spindle are specially designed for machining hard and brittle materials.
We offer the most suitable bond specifications for various materials in the grinding process of hard and brittle materials using a machining/gliding center.
The metal bond wheel has high abrasive grain retention and high sharpness even when machining hard materials. It also has good thermal conductivity, which prevents heat buildup at the machining point and prevents thermal cracking of brittle materials. The tool life is longer than that of electrodeposition tools with a single diamond layer, and it is the best tool for machining ceramics, especially hard SiC and aluminum nitride.
In the machining of quartz glass, the optimum bond selection ensures high grinding durability.

These wheels are designed for high shape precision forming of, for example, motor cores. Wheels of the most appropriate specifications are available for not only magnetic materials such as neodymium-iron, but also for ferrites, ceramics and glass.

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

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.

This single-crystal diamond drill is used for drilling 1 mm or smaller holes in hard brittle materials such as silicone and ceramics. Compared to PCD drills and coating drills it causes less damage to the interior wall of the drilled holes and can significantly reduce hairline cracks and surface roughness, which are usually problems when working with hard brittle materials, thus, providing stable cutting performance.
