The CGW 59085 porous surface grinding wheel is designed for heavy stock removal with a precise finish on tool steels and challenging alloys. This 8-inch diameter wheel features a 1/2-inch thickness and a 1-1/4-inch arbor, making it compatible with standard surface grinding machines that accept a 1-1/4" spindle shaft. The wheel is built with RA Ruby Aluminum Oxide abrasive, a tough, friable grain known for high material removal and good form retention under heavy grinding workloads. The H hardness rating indicates a relatively hard wheel, suitable for maintaining wheel shape while aggressively removing material.
Porous bonding in this wheel supports efficient chip clearance and cooling during grinding, which helps sustain wheel life and achieve consistent finishes on difficult-to-grind metals. The 60-grit size offers a balance between material removal rate and surface finish, making it suitable for rough grinding of tool steels and chrome-containing alloys. The wheel’s specification set—8" diameter, 1/2" thickness, 1-1/4" arbor, Type 1—describes a conventional flat-face surface grinding wheel configured for use on compatible equipment running up to 3600 RPM, aligning with typical industrial grinding operations.
In practice, this wheel should be mounted according to manufacturer guidelines, ensuring proper balance and clamping to avoid runout. It is packaged with a quantity of 10 per box, which supports stocking and production needs in facilities performing frequent heavy grinding tasks. When selecting for a job, verify that the workpiece material and required finish align with the 60-grit Ruby Aluminum Oxide composition and the wheel’s porous structure to optimize material removal while maintaining feature integrity.
