STH 2200

STH 2200 Crankshaft Grinding Machine: Is designed for grinding the crankshafts exactly and a requested quality surface. The one-piece main body, the table and wheelhead with fast aloedynamic feed and provided by a hydraulic system. The operating of the head stock and tailstock displacement on air cushion and the adjustment of headstock motor, with steeples speed of rotation provide an extreme convenience. The movement of the table to the table to the right-left is both manual and automatic controlled. The micrometric wheelhead impulse feed system in the machine also provides a quick and exact work.
