CGW 34070 is a large-diameter surface grinding wheel designed for heavy stock removal and precise finish on ferrous materials. This wheel features a 20-inch diameter, 6-inch thickness, and a 10-inch arbor/shank bore, making it suitable for stationary surface grinders capable of accommodating these dimensions. The wheel is of Type 7 and graded B, with a 46-grit, 83A white aluminum oxide grain composition. The combination of white aluminum oxide grain and a relatively coarse grit supports aggressive cutting action while still delivering a controlled surface finish, which can be advantageous when working with heat-sensitive steels or materials that are easier to grind. The rated operating speed of 1623 RPM aligns with typical industrial grinders compatible with this size and grain arrangement, ensuring the wheel maintains structural integrity under load.
When selecting a wheel of this size and specification, it is important to consider the balance between material removal rate and the finish quality required for the workpiece. The 46-grit profile is suitable for users who need meaningful material removal without sacrificing too much precision. The 83A white aluminum oxide composition offers good performance across a range of steels, including heat-sensitive varieties, and tends to exhibit favorable wear characteristics under normal grinding conditions. Users should verify wheel compatibility with their grinder’s spindle and arbor standards, and follow manufacturer safeguards for wheel guards, mounting, and balancing to preserve tool life and part accuracy.
