Okuma Grinders

Available for both I.D. and O.D. applications and built on stable, heavy-duty platforms,

Okuma CNC grinders have a hydrostatic spindle that uses a thin film of oil to allow the transfer of more power to the grinding wheel. I.D. models grind diameters of 3 mm to 300 mm, using a horizontal spindle that keeps chips away from part surfaces. O.D. grinder models range from small scale, high accuracy finishing machines to heavy-duty units that accommodate parts up to one meter long and weighing up to 330 lbs.
