Product List

This wheel is used for dressing/conditioning the polishing pads used in the flattening process of semiconductor devices.
Electroplated the appropriate abrasive grains of the selected diamond to a base metal brings stable dressing/conditioning, and results in reduced individual differences.

Work materials: Urethan pad, Non-woven fabric pad, Suede pad, which are semiconductor polishing pad

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.

This wheel enables deep milling of difficult-to-cut composite fiber materials such as brake linings, architectural ceramic materials, secondary products of cement, carbon, FRP, and thermoset resins. The amount of ground material removed per unit time is relatively large, which realizes highly efficient grinding. By controlling the contact area between the material being ground and the wheel, this design reduces grinding noise, suppresses additional electric current in the main spindle, and contributes to energy saving.

■Significantly suppresses burr and peel ply (delamination) and realizes high-quality and high-precision machining.
■Reduces mass production cost by removing manual finishing process, realizing long product life, and reusing by re-electroplate.
■Reduction of manual finishing process can suppress precision variation and is effective for finishing junctions which require high precision.

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 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.
