We have achieved smaller diameters (φ0.3–1.5) for PCD drills, which are essential for high-precision machining of hard and brittle materials such as SiC and cemented carbide. With the drill tip composed entirely of PCD, these drills offer a long service life and minimize chipping during drilling. They meet the next-generation requirements for semiconductor-related components, precision mold parts, and other applications.

Compared to conventional diamond resin-bonded grinding wheels, this diamond vitrified grinding wheel offers superior shape retention and is suitable for grinding difficult-to-machine materials such as cemented carbide and SiC molds, as well as for polishing glass materials.

We have developed a multi-flute end mill (φ1–φ3) with cutting edges made entirely of PCD. This tool achieves both high precision and long tool life when machining hard and brittle materials such as SiC and cemented carbide, enabling our customers to achieve high-efficiency machining. A key feature of this tool is its high number of flutes—25 in total—despite its small diameter of φ3.

CBN electroplated wheel suitable for machining high-precision gross shapes by truing after Electroplated. No adjustment on the machine is required, and Ra 0.8μm or less and shape accuracy of ±0.005mm can be achieved.

SUNCREA contributes to improving processing efficiency and reducing costs in hard and brittle materials such as sapphire, carbide, and ceramics, hard magnetic materials such as ferrite and neodymium iron, and iron-based materials such as sintered parts.

Features
1) Good chip evacuation
(2) Stable grindability
(3) Excellent wear resistance and long life
(4) Truing with Electroplated truer is possible (limited to CBN ).

The FINE MASTER series is a wheel that uses "BFM bond" for simultaneous grinding that realizes simultaneous grinding of heterogeneous composite materials such as tungsten carbide and steel materials with high efficiency and high precision, and "BFS bond" for mirror finishing, which realizes mirror grinding of tungsten carbide, steel materials, ceramics, etc. with high efficiency and high precision.

TafRa wheels are Products with higher abrasive grain retention compared to exciting products. In Double disc grinding and centerless grinding, where the spontaneous action of abrasive grains is unlikely to occur, The abrasive grains remain for a long time without falling off, so that the sharpness is maintained and the dress interval is extended. As with existing products, it can be applications with WA dresses and X-POWER dresses.

CBNVitrified bond wheels are manufactured in a variety of sizes, from small-diameter wheels of φ10 mm or less to large-diameter wheels of φ1000 mm, and are widely used in a wide range of applications, including the machining of various automobile parts and the internal grinding of bearings. We also support various applications such as form grinding wheels for angular grinding, centerless wheels, and double-disc wheels with hexagonal pellets.

NEO STAR wheels are bonded with polyimide resin, which has excellent heat resistance, tensile strength, and elasticity. It can be used for grinding that requires long-time shape retention, heavy-duty grinding, creep-feed grinding, efficient grinding of high-hardness steel (HRC67 higher), and grinding of relatively low-hardness steel (HRC40-50 ) that requires long life.

With a focus on consistent quality based on the control of key reamer specifications—such as outer diameter and runout tolerance—our designs can accommodate high-precision requirements, including surface roughness, roundness, and concentricity, as well as high-speed feed rates. We meet our customers’ needs with a wide range of products, from standard specifications to value-added options.

"SUNBRIGHT" is a monocrystalline diamond cutting tool for ultra-precision cutting.
The sharp cutting edges and nano-order level contouring accuracy have been established through high-precision machining technology.
It can be used for various lens products, lens molds, and mirror finishing of non-ferrous metal products.
