G-800 Large Sized Cylindrical Grinding Machine for External Grinding in High Demand
Large OD Cylindrical Grinding Machine
(Model: G-800 x 3000/4000/5000 workpiece length)
Features :
* The wheel head cross feed is driven by hydraulic, which realizes automatic periodical and rapid feed. It can also do rough and fine feed through hand wheel.
* The worktable and wheel head guide way adopt hydrostatic lubrication, its movement on low speed is smooth.
* The spindle is supported by hydrodynamic bearings of high rigidity, ensuring the high rotary accuracy and perfect rigidity.
* The workhead adopts inventer motor to realize variable speed changing.
