Product Description

Internal and External Universal Cylindrical Grinding Machine 
BG-320   BGB-320   BUG-320  BUGB-320   BG-320S   BGB-320S  
  
Performance and Feature:
*With high machining precision, the integral layout of machine tool is rational, appearance is attractive,  operating handles are centralized arranged and visualization, thus to make the machine easy to control  and safe to operate.
*The wheel head adopts a structure of sleeve type bearing bush hydrodynamic bearing mainshafting and  features high rotary precision and high rigidity.
*The feeding guideway uses antifriction & plastic-filming guideway, thus promoting the smoothness and  vibration resistance of low-speed operations.
*The hydraulic drive system uses screw pump which is of smooth running and low noise.
*BGB/BUGB(seimi-automatic) grinding machines can perform plunge-cut grinding or longitudinal  grinding to conduct small-lot or batch production under the control of fixed distance or automatic  measuring device.
*For the BGB/BUGB(semi-automatic) grinding machines, their grinding function and action sequences of  processing cycle are controlled by programmable logic controller(PLC).

Main Accessories:
*Balancing mandrel
*Wheel balancing stand
*Three-jaw chuck(For universal machines Φ130mm)
*Internal grinding attachment(For universal machines)
*Wheel flange
*Coolant tank
*Stand grinding wheel dresser
 
Special Accessories:

*Closed center rest Φ10-Φ75mm
*Open center rest Φ5-Φ50mm
*Four-jaw chuck Φ160mm
*Automatic measuring device (For semi-automatic machines)
*Magnetic coolant separator
