Internal cylindrical grinding machine MKS2 series

for workpieceshorizontalCNC

Overview
This composite grinding machine integrates external cylindrical and internal grinding functions with X, Z1, Z2 and C axes. X axis uses a linear motor direct drive for lateral feed; Z1 is external grinding feed, Z2 is internal grinding feed; C axis is servo-driven for workpiece rotation; Z axis uses an intelligent ball screw drive. Two models are available to match required grinding length and diameter ranges.
