• • • • • • • Main feature
              1. Equipped with Japanese MITSUBISHI control system,the grinder can dynamically display the grinding process by using plasma touch screen
              2. Feeding system is driven by MITSUBISHI servo motor and ball screw,can realize high precise faster approach and high sensitive slower feeding ,the minimal resolution is 0.25um. The speed of the oscillation mechanism is regulated through AC frequency converter.
              3. The speed of the reciprocating motion is regulated through AC．
              4. Equipped with MARPOSS active measuring device．
              5. The grinding carriage and the workpiece feeding systems adopt highly precise and preloaded cross roller guide way with good rigidity and long service life．
              6. The spindle is sleeve structure with frequency conversion adjusting speed.
              7. Enclosed machine guard has beautiful appearance and safe function.
              8. The spindle is used for wheel with variable speed in order to realize to grind at 60m/s high speed.
              9. Product quality and stability, high production efficiency, cost-effective, suitable for high-volume production ring.
