The CGW 34212 is a 7-inch surface grinding wheel designed for precise material removal on ferrous metals. It features a 1/2-inch thickness, a 1-1/4-inch arbor size, and a 60-grit ceramic (AS3) grain structure, with a J-grade hardness to support fast grinding while maintaining control. This wheel is constructed to provide a sharp, consistent cutting action, with a submicron crystal structure that continually fractures to expose fresh grinding points, helping sustain efficient material removal and a finer finish between dressings.
Engineered specifically for heavy stock removal with the ability to achieve tight tolerances, these wheels are suitable for applications where both speed and precision are required. The ceramic composition contributes to reduced dressing frequency, which can translate into lower downtime and more productive grinding cycles. They are described as effective for grinding harder workpieces, including materials near 50 Rockwell C hardness, while maintaining a predictable grind behavior and surface quality.
Practical usage considerations include selecting a wheel with the appropriate diameter, thickness, and arbor to match the grinder and workpiece geometry. With a 7-inch diameter, 1/2-inch thickness, and 1-1/4-inch arbor, this wheel is aligned for standard surface grinding machine tooling, and is packaged as individual units with a box quantity of 10 for stocking and replenishment. Proper dressing and truing remain important to sustain the intended grain exposure and grinding performance over time.
