CGW 34040 is a 20 inch by 3 inch by 10 inch surface grinding wheel designed for precision material removal on heat-sensitive steels and high-speed steels. The wheel features a T7 hardness designation with an 83A white aluminum oxide grain, offering a combination of relatively soft bond and abrasive toughness suited for controlled stock removal and fine finishes. Its 46 grit size provides a balance between material removal rate and surface finish, making it suitable for applications where both efficiency and accuracy are important. The wheel is mounted on a 10 inch arbor, and its 1623 RPM rating indicates a moderate operating speed appropriate for compatible grinders with similar speed capabilities.
The 46-Grit, white aluminum oxide combination is selected to facilitate easy cutting action on all surfaces while maintaining stability during grinding. This makes the wheel an option when grinding heat-sensitive materials, where excessive heat generation must be minimized to prevent loss of hardness or dimensional changes. The product’s construction and grit choice are aligned with general-purpose heavy stock removal as well as precise finishing tasks, depending on the grinding parameters used. Users should verify machine compatibility, including arbor size and RPM, prior to installation and operation.
For packaging and procurement, the wheel is sold in a two-pack, with each wheel sized for a 20" diameter, 3" thickness, and 10" arbor. This configuration supports multiple-workpiece setups or spares for repeat operations. Proper dressing and truing practices should be followed to maintain wheel geometry and consistent performance over time.
