Feature

1. Suitable for grinding inside and outside diameters as well as the end surface of heavy or non-circular workpieces.

2. Heavier workpieces can be more easily loaded to the machine by overhead hoist.

3. Double column designed structure provides better machine stiffness.

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

5. Options of SINGLE-spindle or DOUBLE-spindle, with or without tool changer.

6. Fanuc controller plus 10" screen man-machine touch panel.

7. Conversational programming function makes the control operation and program creation easier to understand.

8. Double-spindle model can be equipped with grinding wheels for both high and low RPMs; also, both large and small grinding wheels can be used.
