hermal deformation. 3 the pedestal, workbench. Lathe body and beam are made of ferrosteel with high strength and high abrasive resistance , tempering treatment, eliminate internal stress and deformation. 4. The guide surfaces of lathe body, beam and ram using accurate grinding¡¢good interface and high precision. Beams with hydraulic two-spot locking, feeding is large, without tremble. 5.Machine tools feeding is driven by ac servomotor, ball screw drive. The beam and vertical tool posts are covered with sealing shied which make the lathe more safe and easy to operate. 6.The main shaft of the lathe is driven by ac motor. With the 16 step speed changing mechanism to the main shaft. Achieved the workbench rotate speed range. 7 imported or home-made controlling systems can be adopted according to user¡¯s needs.
