Alpex Wheel Co. has introduced COOL BLUETM, a new vitrified PCD grinding wheel. This new generation grinding wheel reduces grinding times by 30% and improves grinding ratios by 50%. In order to achieve this significant improvement in performance, COOL BLUE was designed to run at lower temperatures, reducing buildup during the grinding operation. Chip flow and coolant access to the PCD workpiece are optimized, and lower operating temperatures reduce grinding wheel edge wear. Additional benefits include reduced wheel loading and increased lubricity.
