Horizontal Spindle Rotary Surface Grinding Machine

CRG - H6

The CRG-H6 is designed for precision grinding of parts up to 600mm in diameter. It is able to quickly effectively remove stock from a variety of materials including steel, ceramic, silicone and cast iron. Capable of holding flatness and parallelism to +/- 0.005mm. Work-pieces can be clamped centered or multiple parts can be ground positioned off center. Due to the rotating table, the grinding wheel is almost continuously in contact with the workpiece, resulting in higher productivity compared with standard surface grinding due to the elimination of the continuous table reversals.
