The CGW 58026 is an 8 inch diameter surface grinding wheel designed for heavy stock removal and precise sizing on metal surfaces. It uses PA-46H pink aluminum oxide grain, a formulation chosen for efficient cutting and good performance on tool steels and hard alloys. This wheel features a 1-1/4 inch arbor and a 3/4 inch thickness, with a Type 5 designation and a 46 grit size, offering a balance between aggressive material removal and achieving a controlled finish. The pink aluminum oxide composition is selected for improved durability over some standard WA grains, particularly at light to moderate feed rates, which can help with consistent stock removal and predictable grind geometry.
The wheel is specified for use in applications where heat-sensitive materials require a cooler cutting action and minimal thermal distortion. It is intended for sharpening and grinding tool steel and is suitable for scenarios that demand fast yet controlled cutting of hard alloys. Operators should consider appropriate grinding parameters to maximize wheel life and surface quality, including feed rate, wheel speed, and workpiece material. The packaging notes indicate the wheel is sold per piece with a typical box quantity that supports multiple-workpiece setups, enabling efficient batch work without frequent reordering.
Compatibility considerations include the wheel’s 8" diameter and 1-1/4" arbor, which must match compatible grinders and mounting hardware. Proper mounting, balancing, and following manufacturer safety guidelines are essential to achieve the described performance. When selecting consumables, verify the grit, hardness (H), and grain type (PA pink aluminum oxide) align with the specific tool steel or alloy being processed, and ensure proper ventilation and PPE are used during grinding operations.
