External cylindrical grinding machine MK series

glassworkpiecehorizontal

Overview
The machine adopts a T-shaped movable table layout. Foundation members are produced by resin sand casting; main structure is HT300 pearlitic cast iron for high stiffness and dimensional stability.
Numerical control manages X and Z axes independently and enables X–Z two-axis linkage for automated external cylindrical grinding.
Suitable for grinding workpieces in special materials (glass, sapphire, silicon carbide, carbon fiber, etc.) and for components such as reducers, tool handles and cylinders used in industrial applications.
