The CGW 34038 surface grinding wheel is a 20-inch diameter wheel designed for heavy stock removal with a precise finish. Made with 46-grit black silicon carbide, it falls under the T7 type and carries an I grade hardness, suitable for controlled material removal when grinding non-ferrous metals, as well as carbide, granite, ceramic, and chrome workpieces. Its 3-inch thickness and 8-inch arbor/shank size are configured to fit compatible surface grinding machines and setups that accommodate larger wheel formats, enabling efficient material removal while maintaining dimensional stability on the workpiece.
The wheel’s composition—72C black silicon carbide grain—provides a balance of hardness and fracture resistance for coarse to mid-range finishing tasks. The combination of grain type and grit size is selected to support consistent cutting action and a reliable surface finish on appropriate non-ferrous and hard material substrates. This product is packaged as an individual wheel, with a box quantity of 2 per package, aligning with common industrial stocking practices for wheels used in high-volume grinding operations.
When selecting this wheel, it’s important to verify machine compatibility with the wheel diameter, thickness, and arbor sizing, as well as RPM ratings appropriate for the tool and spindle. Operators should observe standard grinding safety practices and ensure appropriate cooling and dressing procedures to preserve wheel integrity and achieve the intended finish on target materials.
