CGW 34063 20" x 6" x 8" T7 91AB-46I 46-Grit Premium Blue Aluminum Oxide Surface Grinding Wheel is designed for heavy stock removal with a precise finish on tough materials. This wheel features premium blue aluminum oxide grain and bond technology that emphasizes both sharpness and durability, making it suitable for demanding grinding tasks where heat build-up must be controlled. The combination of grain and bond is selected to provide efficient material removal while helping maintain part dimensional accuracy during high-speed grinding operations.
The wheel is specified as 20 inches in diameter, 6 inches thick, and with an 8-inch face dimension, using a 10-inch arbor/shank size. It is classified as Type 7, with a 46 grit and a Grade/I hardness designation that supports stable cutting behavior under load. With a rated RPM of 1,623, this wheel is intended for use on appropriate grinding machines where high rigidity and balance are maintained to ensure smooth operation and consistent surface finish. The 46-grit premium grain provides a balance between material removal rate and the quality of the finished surface, while the AZ bond contributes to durability and extended wheel life in demanding applications.
This wheel is well-suited for applications involving heat-sensitive alloys and mold steels, including high-speed steel work under 58 RC, where maintaining dimensional integrity and minimizing heat-affected zones are important. Practically, users should verify machine spindle compatibility with the 10" arbor size and ensure correct mounting to maintain balance. As with all grinding wheels, proper wheel conditioning, dressing as needed, and adherence to safe grinding practices are essential for achieving consistent results and extending wheel life.
