DCM Tech’s SG 7100 resurfaces heavy truck and auto rotors to OEM or better finish and accuracy in minutes. Crosshatch ground finish provides a precision friction surface assuring optimum braking performance and brake pad life. There is less stock removal than turning methods, keeping rotors in service longer, saving money and resources while providing a superior surface finish. Repair and Re-Use rather than replace, while increasing productivity! Rotors can be resurfaced in as little as 5 minutes with the easy to use bi-directional autofeed system. Wet grinding eliminates airborne dust and provides consistent results.
