The CGW 34059 is a large-diameter surface grinding wheel designed for heavy stock removal and precision finishing on a variety of metals. With a 20-inch diameter, 4-inch thickness, and a 10-inch arbor/shank, this wheel is configured as a T7 83A-46D grade wheel, featuring 46-grit white aluminum oxide grain. The white aluminum oxide formulation and grain size are chosen to balance aggressive material removal with a controlled, stable grind, making it suitable for applications that require both efficiency and a fine finish on ground surfaces. The D hardness rating indicates a robust wheel that can maintain shape under typical surface grinding pressures, helping to achieve consistent results across the workpiece.
The wheel’s construction and grain type are documented to support reliable performance in metalworking environments where heat-sensitive steels or high-speed steels are involved. The 83A (white aluminum oxide) grain is known for good cutting action and longevity on a range of metals, while the 46-grit size provides a balance between rapid stock removal and the ability to produce a smoother final surface. This makes the wheel appropriate for tasks requiring light to moderate finishing work after bulk material removal, as well as for general-purpose surface grinding where precise size and finish are important.
When selecting this wheel, consider the compatibility with grinding machines that accept a 10-inch arbor and the need for appropriate wheel guards and cooling practices to sustain performance and wheel life. The package is listed as a single unit, which may influence stocking and procurement workflows in facility-maintenance or metal fabrication settings. Maintenance considerations include inspecting for cracks or glazing and ensuring the wheel is mounted per manufacturer guidelines to maintain dimensional accuracy and surface quality.
