The grinding head adopts high-efficiency synchronous energy-saving motor, with stable speed and up to 40% energy saving. The thickened frame and bottom plate, the new beam swing structure design, the whole machine runs stably, the beam swing speed can reach 60m / min at most, and the polishing efficiency is high. T1 (l140mm) or T2 (l170mm) Abrasives can be installed, which has high efficiency and saves abrasives, Equipped with plate shape contour scanning detection system and grinding head lifting height control system, the edge and corner polishing quality is better and the degree of automation is high. Equipped with electronic ruler abrasive detection system, the corresponding grinding head abrasive can automatically alarm and remind the operator to replace the abrasive. With a high degree of intelligence, the large-size touch screen is adopted, and the parameter adjustment is more convenient.
