Product Features

Mechanical structure

Suitable for grinding inside and outside diameters as well as end surfaces of heavy or non-circular work pieces.

Heavier work pieces can be loaded more easily by overhead hoist.

Double-column structure provides better machine stiffness.

Fully enclosed covers and an oil-mist reclaiming device prevent leakage of grinding oil and mist.

Smart Operation

Options of single- or double-spindle, with or without tool changer.

Fanuc controller plus a 10" man-machine touch panel.

Conversational programming makes control operation and program creation easier.

Double-spindle models can carry grinding wheels for both high and low RPM.
