Product Description

Heavy Duty High Precision Universal Cylindrical Grinding Machine 
BG-320C   BUG-320C   BG-320C/1   BUG-320C/1
 
Features and Performance:
*This machine is used for grinding internal and external surface of cylinder and taper. It is suitable for  processing of single and small batches of parts in machining work shop, tool work shops, tool shops  and repairing shops.
*The wheel head spindle uses our own technology, with the characteristics of high rotary precision, good  rigidity, and high grinding quality. Being made of materials of nitrogen treated 30CrMOALA, the spindle is  of the hardness up to HV900 and good precision maintaining.
*The work head mainshafting uses our own capacity, with the characteristics of high precision, good  rigidity. And grinder surface roundness of internal & external cylindrical parts fixed on the chuck is higher  than the requirements in the national standards.
*The wheel head feeding guideway uses antifriction & plastic-filming guideway, thus promoting the  smoothness and vibration resistance of low-speed operations.
*The hydraulic driving system uses screw pump which is of smooth running and low noise.
*The operation system is of integrated operation by a single handle of an operation box and the electric  controlling buttons are centralized so that the operations are easy and reliable.
*The function of grinding with worktable shuttling (60 times/min) can be used to meet special order.
 
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-Φ100mm)
*Opened center rest (Φ10-Φ100mm)
*Four-jaw chuck (Φ160mm)
