- T6: HF Fischer spindle MFV or MFZ 1224/1242/1260
- T7: HF Fischer spindle MFV or MFZ 1224/1242/1260
- Marposs tool measurement
- active longitudinal positioning
- Elaso GAP-control on T1 and T2
contactless integrated in the control surface
- Elaso GAP internal grinding with fluid sensor for T6 and T7
- semi-automatic balancing by Elaso
integrated in the control surface for T1/T2
- tailstock hydraulic with fine adjustment +/- 150 microns
- dresser on workpiece spindle side table mounted
- dresser on tailstock side table mounted
- dresser on upper table
- new service- and userfriendly housing

SPECIAL EQUPEMENT:

Workhead with direct drive
- strongly recommended for
non-circular grinding
- workpiece weight flying max. 75kg
- workpiece weight between centres 150kg
- water-cooled

B-axis with direct drive
- center height 225 mm
- extremely torsionally stiff
- highly accurate positioning
- resolution 0.000001341°
- water-cooled

Hydrostatic ball screw - x-axis
- wear-free, as there is no contact during operation
- no loss of precision, even during long-term use at full load and
maximum speed
- no friction at low speeds
- no friction force backlash when the direction of rotation changes
- translates even the smallest rotational movements
- no stick-slip effect even at low speeds
- no fluctuations in frictional torque due to ball circulation
- higher axial stiffness compared to ball screws
- significant improvement in damping, resulting in better workpiece surface
finish and tool life
- no oscillations due to ball circulation
- also suitable for high speeds and accelerations
- cost-effective alternative to the linear motor with greater precision and
significantly lower heat generation
- significantly less power dissipation and, as a result, no problems with swarf
on permanent magnets

New hydraulic unit
- optimized temperature control (chiller)
- Energy-saving
Only one pump controlled by VFD
- Pressure monitoring
- monitoring of the hydrostatic oil for
water content.
(Damage to the bellows is recognised and detected prematurely)
-fine adjustment +/- 150 microns

Paper belt filter
375l – alternative 480l

Grinding mist extraction system – emulsion

MECHANICAL OVERHAUL
-complete machine according to Kellenberger protocoll
-new painting




ELECTRICAL OVERHAUL
- new modern Fagor CNC with BEMA HMI
- new electric cabinet
- new digital drive technology
- replacement of all electrical cables, switches etc.
