The CGW 34779 is a 12 inch diameter surface grinding wheel designed for heavy stock removal with the capability to achieve a precise finish to meet specific size requirements. The wheel employs white aluminum oxide grain, which is selected for a balance of cut rate and durability on a range of materials, including heat-sensitive steels where control of grinding action is important. The Type 7 (cup-style) wheel configuration is suited for grinding operations where access to the workpiece is limited, enabling efficient material removal and finish consistency within industrial maintenance routines.
Constructed with a 2 inch thickness and a 5 inch arbor/shank size, this wheel is configured to integrate with compatible grinding machines that accommodate a 12" x 2" x 5" wheel format. The WA-46J designation indicates a particular grain size and hardness pairing: 46 grit with a J hardness, which influences the balance between aggressiveness and wheel life. Operating at up to 2220 RPM, the wheel is intended for standard continuous or intermittent grinding cycles typical in facility maintenance and metalworking environments. Proper selection of wheel type and grain is important to control stock removal versus surface quality, especially when grinding heat-sensitive alloys.
Practical use considerations include ensuring proper mounting to compatible grinders, using appropriate guards and coolants as required by standard shop practices, and selecting this wheel when easy cutting action on all surfaces is desired but with a need for controlled material removal. This wheel is packaged as a single unit and is suitable for use in maintenance workflows that require a 12" wheel with a 5" arbor, aligning with specific machine spindle configurations and safety procedures for wheel changeouts and grinding operations.
