OHG-300 model is basically developed for speedy processing of high precision gear with stable quality.
The conclusion was reached by connecting grinding spindle and workpiece spindle directly to the motor which, using (EGB) CNC equipment, control micro vibrations and backlash due to gear shift.
Also, to help measure the rigidity and strength of machine bed which has significant impact on accuracy, each of the other axis are made direct drive.
Furthermore, because the hydraulic units are separate from the machine, this reduces possibility of rising inner temperature and O.B.D. dimensions variability hence stable processing is made possible.
