DMG MORI IGH-7NT

The IGH-7NT is a CNC internal grinding machine for precision bore, face and taper grinding. A turret-type wheelhead carries one internal and one external grinding spindle, so ID, OD, face and taper grinding can be done in a single clamping. An NC swivel table on the headstock, set in 0.0001° increments by NC command, is standard equipment for taper grinding.
