Metal bond wheels for surface grinding of wafers such as SiC and GaN. The ultra-porous structure realizes fine grain grinding, which could not be applied with conventional metal bond wheels, and has excellent sharpness and wear resistance compared to vitrified bond wheels of the same particle size.

AG(Array Grain) wheel.
The outstanding sharpness prevents clogging and burn mark, and the service life is more than twice as long as that of conventional Electroplated. It can be used for profile type and is effective in a wide range of machining operations from roughing to finishing.

Electroplated wheels are equipped with thread-like irregularities on the outer circumferential surface and are specialized for processing that requires sharpness.

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 ).

SL Tools (our trademark registered name : STAR LAYER) that has a structure in which only one layer of diamond abrasive grains is fixed to a precision-machined metal core by means of a roller Compared to electroplated tools, the abrasive grains are firmly bonded to the base metal, and the retention strength is strong and the protrusion is large. The arrangement and spacing of the abrasive grains can be adjusted to improve sharpness and prevent clogging, making it suitable for a wide range of applications and tool shapes from roughing to finishing.

Wheel with electroplated shaft that is specialized for machining ceramics used in semiconductor manufacturing equipment parts, etc., and provides stable sharpness with high accuracy, high efficiency, and long life. The Ceramate Drill dedicated to the center-through type with high cooling effect and revolutionary machining speed for highly efficient machining, the Ceramate End Mill as a grooving tool, the Ceramate Tap as a threading tool capable of machining JIS Class 2 precision (M3 to M12) screws with half the number of threads to reduce tool load, and the Ceramate High Speed Cutting Tool for high efficiency contour cutting. The Ceramate Contouring is a high-efficiency contouring tool that enables high-speed feed 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.

Diamond wheels with varying bonding materials such as curve generating wheels, pallets, lens centering wheels and grinding wheels are used for grrinding camera and binocular lenses, prisms, etc.

This wheel is used for grinding thin glass used in displays such as TVs, PCs, and smartphones.

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.
