PROTH PSPGP 1522 AHR CNC Surface Grinding Machine was manufactured in 2006 by PROTH Industrial Co., Ltd in Taiwan. The machine has a large table with an area of 1500x2200m and a rigid gantry (two-column) structure which allows grinding of very large elements (forms, dies etc.). CNC control facilitates the operator’s work and enables precise machining of complex shapes.
