Horizontal machine column X = 3,000 mm
Vertical headstock slide Y = 1,300 mm
Headstock horizontal-transverse Z = 1,300 mm
DRIVE SYSTEM
Drive of the X, Y and Z axes by means of digital feed drives for
contour-accurate work with constant torque.
– Feed rate / rapid traverse in all axes 2-30,000 mm/min
– Acceleration values in all axes 2 m/s²
– Drive of the X-axis via a ball screw Ø80 mm
– Y-axis drive via a Ø63 mm ball screw in conjunction with a hydraulic counterbalance
with hydraulic weight compensation
– Drive of the Z-axis via a ball screw Ø63 m
SAFETY GLASS VIEWING WINDOW DESIGN
The viewing windows of the front angled sliding door and the side pedestrian
access door are made of safety glass. The side of the pane facing the
side of the pane (glass) facing the working area guarantees greater resistance to
the polycarbonate pane, ensures greater resistance to the effects of
cooling lubricant emulsion and swarf.
ELECTRIC DOOR DRIVE
The counter-opening angled sliding doors of the UniSpeed are equipped with an
electric drive. The doors are opened/closed by means of
buttons on the control panel.
To close the doors, 2 buttons must be pressed and held down.
pressed. The doors can also be opened under programme control
programme-controlled, provided the local conditions rule out the risk of crushing.
It is not possible to open the doors manually.
MAIN DRIVE
Driven by a frequency-controlled, liquid-cooled AC motor. The
power is transmitted directly to the milling head without an intermediate gearbox.

TOOL HOLDER SK 50 BIG-PLUS
Unless expressly described with a different tool holder,
all relevant machine components (milling head, tool changer,
magazine) are adapted to the SK 50 BIG-PLUS tool holder.
The tool pull-in force on the milling head is 20 kN.
MILLING HEAD INTERFACE 3-POINT / HIRTH
The orthogonal milling head / universal milling head is equipped with a flat-toothed nozzle ring
(Hirth ring) with integrated 3-point support. This
enables the retrofitting of supported tools (e.g. angle head).
