CGX CNC Crankshaft grinding machine

The new challenge for the engine rebuilding

New line of machines customized for both engine rebuilders
and the high production needing. An economic solution with
the most advanced technologies.

  • CNC control system Sinumerik 840 D
  • Siemens Servomotors
  • Linear encoder on X and Z axis
  • In-process measurement system with fork

 

TAILSTOCK

  • Tailstock are made of highly resistance cast iron, stabilized.
  • The tailstock can move by motor and manually on the table by air cushion and gear and rack.
  • The pressure of the tailstock quill is continuous controlled by a load cell.
  • The movement and pressure of the sleeves are made by hydraulic system.
  • The tailstock permit the cylindrical manual correction.

HEADSTOCK

  • The headstock can move by motor and manually on the table by air cushion and gear and rack.
  • Headstock rotation is made by Siemens servomotors.
  • The headstock can be equipped with 3 auto centering jaws chuck or 4 independent jaws chucks.

WHEELHEAD UNIT

  • Strong structure, thermally stabilized, with scraped surface in order to secure the highest precision of linearity and atness in the different positions of the grinding wheel head.

  • The movement of the grinding wheel is made by pre-loaded ballscrew with double nuts and position is controlled with Heidenhain linear encoders with precision and repeatability of 0,003 mm.

   

WHEEL DRESSER

The machine is equipped with diamond single point dresser. The machine can be supply with diamond wheel dresser

STEADY REST

Machine can be supplied with standard or narrow steady rest (2 pieces each) or with automatic self centering steady rest
