Diamond Grinding Wheels for Chamfering

Product Overview

High performance wafer edge grinding wheel with shape retention and high sharpness and long life

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.

Application

• Edge grinding on the outer of wafer, rough and finish grinding

Types of Adhesives

• Metal
• Resin
