These are metal-bonded wheels designed for grinding the surfaces of wafers, including SiC and GaN. Their ultra-porous structure enables fine-grit grinding that was previously impossible with conventional metal-bonded wheels, and they offer superior cutting performance and wear resistance compared to vitrified-bonded wheels of the same grit size.

An electroplated wheel featuring helical grooves on its outer surface, designed specifically for machining operations that require a sharp cutting edge.

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 ).

Brazed Diamond Tools "STAR LAYER" (Our registered trademark name: STAR LAYER) are tools that have a structure ㏌ which diamond abrasive grains are fixed ㏌ a single layer on a precisely machined base metal using brazing material. In contrast to electroplated tools, the abrasive grains are firmly bonded to the base metal, giving them strong retention strength and a large protrusion. In addition, the arrangement and spacing of the abrasive grains can be adjusted, and by taking advantage of the improved sharpness and the characteristics of being less prone to clogging, it can be used for a variety of applications and tool shapes (Diamond Core Drills, Diamond Cutters, Diamond Wheels, etc.) from rough processing to finishing processing.

An electroplated-shaft wheel specialized for machining ceramics used in semiconductor manufacturing equipment components, offering high precision, high efficiency, a long service life, and consistent cutting performance.The Ceramate Drill, designed exclusively for center-through tools, offers excellent cooling performance and achieves high-efficiency machining at groundbreaking speeds; the Ceramate End Mill for grooving; the Ceramate Tap, a thread-cutting tool capable of JIS Class 2 precision (M3–M12) that reduces the number of threads by half to minimize tool load; and the Ceramate Contouring tool, a high-efficiency contouring tool capable of high-feed-rate machining.

In the manufacturing process of semiconductor devices and wafers, the demand for planarization is increasing year by year as wiring becomes finer and more multilayered. In the CMP process, which is used as a planarization technology, the conditioning of polishing pads plays an important role in stabilizing polishing characteristics, and we have been providing high-quality, highly reliable conditioners for over 25 years. We continue to contribute to the stabilization of the CMP process, offering conditioners in a variety of shapes and specifications to meet diverse needs.

Small-diameter formed wheels are used to finish the notches of large-diameter wafers. Our notch grinding wheels maintain the run out accuracy of diamonds to the shank, and realize a favorable wafer circumference. As with our edge grinding wheels, we are able to provide a wide variety of specifications, including single-grooved wheels, multi-grooved wheels, and wheels for both rough and finish grinding.

Metal bond wheels and resin bond wheels are used in edge grinding on the outer circumference of silicon wafers, which requires uniform sharpness in addition to precision accuracy in the shape of the wheel and abrasion resistance. We are able to provide a wide variety of specifications, including single grooved wheels, multi-grooved wheels, and wheels for both rough and finish grinding.

Diamond metal wheels and diamond resin wheels are used for grinding silicon ingots for solar cells and semiconductors. Drawing on our proven track record across various industries, we provide wheels tailored to our customers’ needs and the machinery they use.

Cutters with a metal base are available in "multi-cutters" and "single-blade types. Multi-cutters can cut and groove by combining multiple cutters with specifications suitable for the work material. Our unique technologies such as cutting edge shape, pitch accuracy, and accumulation accuracy realize high machining quality. The single-blade type is a cutter with a diamond or CBN abrasive grain layer formed on the periphery of the steel steel core. Electroplated, metal, or resin can be selected for the bond, and the cutting edge shape (V-shape, R-shape) and steel core shape (all relief, under-neck relief) can also be selected according to requirements.

Dicing blades come in two types: “hub type” and “ring type.” The hub type is primarily used for dicing semiconductor silicon and compound wafers. It features an aluminum base and a nickel-bonded diamond layer integrated into a single unit, making it easy to handle. The ring type can be used for a wide range of applications, including cutting and grooving not only semiconductor silicon and compound wafers but also various packaging materials and electronic component materials.There are three types of bonds to choose from: electroformed, metal, and resin. The electroformed bond allows for the production of ultra-thin blades with a thickness of 15 μm.Resin bonds are frequently used for cutting glass, ceramics, and various packages such as QFNs, where chipping and cutting resistance must be minimized. Metal bonds offer a wide range of options—from high-rigidity types comparable to electroformed bonds to types with superior cutting performance—allowing you to select the bond best suited for your specific workpiece material.
