The CGW 34039 is a bluntly specified, high-performance surface grinding wheel designed for heavy stock removal where precision and size control are critical. With a 20" diameter, 3" thickness, and a 10" arbor/shank compatibility, this wheel is built to fit larger grinding setups that demand robust material removal while maintaining accuracy in the final workpiece.
Constructed with premium blue aluminum oxide grain (91AB) and a T7/46-Grit composition, the wheel combines sharpness with durability to support fast, cool-cutting action. This balance is particularly advantageous when grinding heat-sensitive materials, such as alloy steels and high-speed steels below 58 RC, helping to reduce heat buildup and potential workpiece distortion during operation. The I hardness designation indicates a relatively firm bond that supports durable performance under demanding grinding conditions, while the wheel’s design emphasizes a reliable, consistent finish through sustained use.
Typical applications include material removal and precision finishing on large surface areas, where maintaining strict size and flatness tolerances is important. Operators should verify compatibility with their grinder spindle and nose-to-face geometry, and ensure appropriate dressing and truing procedures are followed to maximize wheel life and consistency. The package specifies a two-wheel per box arrangement, with each wheel prepared for integration into suitable surface grinding equipment that accepts a 10" arbor. By aligning wheel type, grit, and bond with the workpiece material and required finish, users can achieve predictable performance while managing grinding temperature and tool wear.
