- 800 x 3000mm, 800 x 4000mm, 800 x 5000mm;
Features:
* The table longitudinal traversal is actuated by hydraulic means at step lessly variable speed or operated by means of hand wheel.
* The wheel head rapid approach and withdrawal and intermittent feed are effected hydraulically, the wheel feed can also be operated by hand.
* The wheel head cross feed is driven by hydraulic, which realizes automatic periodical feed and rapid feed. It can also do rough and feed feed through hand wheel.
* The work table and wheel head guide way of the G-500, G-630 series adopt hydrostatic lubrication, its movement on low speed is smooth.
* The spindle of G-500, G-630 series is supported by hydrostatic and hydrodynamic bearings of high rigidity, it makes the spindle have high rotary accuracy and perfect rigidity.
