Double-Disc Grinding Services - TCI Precision Metals

Double-Disc Grinding uses two opposing abrasive wheels to simultaneously grind two sides of the material. In one operation, equal amounts of material are removed from both sides. Grinding two sides of a part at the same time provides greater control of dimensional tolerances, flatness, and parallelism.
