Product Description

Large-size Heavy Duty Universal Cylindrical Grinding Machine 
BG-500   BUG-500   BG-630   BUG-630 
 
Features and Performance:
*BG-500/BG-630 type cylindrical grinding machines are sutiable for grinding external cylindrical surfaces  of rotary workpieces of cylinder and taper.
*BUG-500/MBUG-630 type universal cylindrical grinding machines are suitable for grinding external or  internal surfaces rotary work-pieces of cylinder and taper.
*The longitudinal movement of the worktable is driven by hydraulic stepless variable speed transmission  or
hand-wheel transmission; The guideway is covered by soft pad and features on pressed oil  lubrication, absorbing vibration, anti-friction as well as smooth low-speed operations.
*For the wheel head, its fast forward/backward of infeed is driven by hydraulic system, while rough and  refined feed is controlled hand-wheel transmission. The grinding wheel spindle is supported by high-  rigidity sleeve type hydrostatic/hydrodynamic bearing, with the characteristics of high rotary precision and  high rigidity.
*The work head adopts the way of double-speed motor-three-gear transmissions, with the characteristics  of high transmission precision, good rigidity and easy-to-operate. The work head spindle of universal  type  is of the structure of sliding bearing and the clearance of fore bearing is adjustable for adapting to  meet  the needs of installing center or chuck in grinding.
*The work head spindle of universal type can e adjustable in counter-clockwise direction for any angle  within 90 degrees so as to facilitate the grinding of internal or external taper workpieces with chuck.
*For the series of universal type, they are with the function of internal grinding; with the internal grinding  spindle supported by rolling bearing, four rotary speeds can be achieved through replacing belt pulley in  order to grind internal cylindrical workpieces of various diameters.
*The wheel dressers are respectively installed on worktable and tailstock and provided with two kinds of  dressing.
*With a rational integral layout, the operating handles of the machine tool are centralized arranged and  visualization, thus to make the machine easy to control and safe to operate.
