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
