GRINDING MACHINE FOR ENGINE VALVES SEAT

The grinding machine RSB has been designed to machine the seat surface of internal combustion engine valves.

The RSB great flexibility allow to machine engine valves of different sizes and seat angles with a very fast setup time. The grinding wheel has a Ø 610 mm.

MAIN COMPONENTS
  • Workpiece slide with spindle and motorization. It’s used for loading and unloading the valve, it transmits an opposite rotation to the valve compared to the grinding wheel. It holds up the valve coaxial with the spindle. It is equipped with an ejector of the processed valve
  • Grinding wheel slide with spindle and rotation pin. The slide can rotate around the vertical axis to machine valves with different seat angles. Seat angle change fully automatic CNC controlled.
  • Oscillating slide.. It gives the grinding wheel an oscillation along the horizontal plane to improve the finishing quality level.

  • Dresser spindle. It transmits the rotation to the dresser roll used for the predetermined dressing cycle of the grinding wheel.
  • Positioning system during valve loading.. It allows the correct positioning of the valve during the clamping by the spindle gripper. The valve face is the positional reference.
  • LoaderPneumatic system to pick up the valve from the inlet conveyor and lifting it to the spindle level. Then after processing it unloads the valve on the oulet conveyor
  • Grinding wheel automatic balancing system.
