AKP2W Landing gear grinding machine double wheelhead

Machine is made with 3 separate bases: • A Longitudinal for grinding wheel head • B In the front for headstock • C In the front for workheads Bases are made of high resistance cast iron, thermically stabilized. With one flat and one “V” guide. Surface are scraped in order to secure the highest precision of linearity and flatness

 

 

 

 

 

WHEELHEAD UNIT

The cross movement of wheelhead slide is given by a very high precision preloaded recirculating ball screw driven by an axis brushless motor made by Siemens and position control with Heidenhain linear scale controlled by the CNC (X Axis). The longitudinal movement (Z Axis) is made with a preloaded ballscrews. The machine has a double grinding wheel head that rotate on position 0° and 16° automatically. The locking of rotation is made by oleodinamic clamping. For change of angular wheelhead position between 0° and 16°:

accurancy of positioning - 0.01 mm
repeatability of positioning - 0.005 mm

Wheelheads drives will be additionally protected against coolant with covers reisstant to CIMTECH 46 coolant Wheel guards will be designed to limt quantity of coolant directly impacted on linear axes covers

 

     

      

 

THE TECHNOLOGY

The machine has installed

  • probe for measuring of diameters of grinding wheel.

wheel measuring includes:
- wheel diameter measure
- Z axis measure of wheel edge for every grinding edge
Complete automatic wheel measuring procedure for every type of wheel will be prepared, tested and supplied.

         
  • In-process measurement system
  • Monitoring system for machine tools
