Harig Kool-Grind System
Harig's patented Kool-Grind System revolutionizes dry grinding by maintaining cool workpiece temperatures as you grind. An internally colled Plate and/or Chuck paired with the self-contained Chiller enables the Kool-Grind System to keep your workpieces cool. Heat generated in the workpiece during the machining process is absorbed by the Plate or Chuck instantly, without messy external coolant or mist systems.
The Kool-Grind System prevents parts from warping due to temperature fluctuations, and eliminates down time caused by waiting for pieces to cool. Without the fear of warping, you can leave less grinding stock on your workpiece, achieve closer tolerances, and reduce grinding wheel breakdown.
When dry-grinding, Harig's Kool-Grind System improves your accuracy, increases production rates, and adds repeatability by cooling workpieces without external coolants. Full repair service and replacement parts available. Reliability backed by Harig's trademark service.
