MACHINE COLUMN
Compact torsion resistant fabrication with screwed-on, hardened flat guideways. Telescope steel covers for protection against chips and coolant.
HEADSTOCK SLIDE
Cast iron with hydraulic counter weight, guided at the machine column via combined antifriction roller guideways.
MACHINE BED
Flat bed design, for fast and safe travels of the machine column in the X axis. The guideway width of 1200 mm combined with compact anti friction roller guideways grant highest precision.
AUTOMATIC UNIVERSAL MILLING HEAD
with headstock, consisting of
– Milling head adapter, automatic rotation 340 x 1°
– Pull-in force of the Hirth coupling approx. 125 kN
– Milling head, automatic rotation 180 x 1°
– Pull-in force of the Hirth coupling approx. 100 kN
– 61.200 full degree positions can be positioned,
programmed and processed in cycles via the CNC system
– The milling spindle is equipped with a
Hydro-mechanical tool clamping system
– Tool clamping force: 25 kN for safe operation at high
cutting forces
– Tool taper SK 50 DIN 69871
MAIN DRIVE 37 KW
– 37 kW (at 100% duty cycle continuous load)
(53 kW at 40% duty cycle)
– Force ventilated AC motor with 2-step gear, automatic switch-over,
depending on programmed speeds.
– Speed range 22 – 4000 rpm
DIGITAL FEED DRIVES
– for high precision contour machining via
AC motors with constant torque.
Continuous feed and rapid traverse range:
– Y axis = 2-12.000 mm/min
– Z axis = 2 – 15.000mm/min
– X axis = 12.000 mm/min
OPERATORS PLATFORM WITH INTEGRATED CONTROL STATION
travelling in X‑direction:
The platform is located at the side
of the machine column. At the side
facing the work area, a door with electrical safety
interlock and sight window is provided.
Additionally this platform travels, independent of the
machine movement, in vertical direction.
With the machine at standstill, this platform travels
horizontally by 1000 mm
2nd CONTROL PANEL
switchable, mounted on a swivel boom in front of the machine.
CNC System Heidenhain iTNC 530
AUTOMATIC LEVEL REGULATION OF THE HEADSTOCK
Electro-mechanical control via 2 vertical ball screws with
separate drives, measuring systems and CNC axes to ensure a long-
lasting, accurate, co-planar and low-maintenance travel of the headstock.

MEASURING SYSTEMS
Direct, non-contact measuring via linear scales for
high precision production.
ELECTRICAL EQUIPMENT
According to EN 60204, VBG 4 for 400/230V (±10%) 3 phases, 50 cycles Control voltage 24 V. Total power approx. 80 kVA, 125 A.
LUBRICATION
Main drive and milling head adapter: Circulating oil lubrication
Main spindle: Permanent grease lubrication
Guideways and recirculating ball screws: Central pulse lubrication
COLLISION MONITORING SYSTEM 1-CHANNEL
to monitor machine and, conditionally, tool collisions.
Function:
A piezo force sensor measures all deformations during machining or on occasion of a collision. The sensor signals are evaluated by the CMS monitoring device.
INCREASED COOLANT INSTALLATION
for tools according to DIN 69871-AD50 with internal coolant
supply, in addition to the spray ring, inclusive of paper band filter unit for cleaning of coolant.
Coolant supply internal/external; pressure switchable via bypass valve.
Pump capacity. max. 50 l/min at 10 bar
max. 47 l/min at 16 bar
COOLANT-AIR
Switchover from internal or external coolant supply to air
OIL COOLING UNIT
to stabilize operating temperature in the headstock, thus increase of the machining accuracy.
CLAMPING PLATE
Surface special casting
T-slots DIN 650 28 mm H12, slot distance 250 mm
Size 5.000 x 2.000 x 300 mm
FINE LUBRICATOR
(System ACCU – Lube dosing unit)
For optimization of machining sequences as well as to increase
tool life. No need for disposal – the lubricant, as a standard, uses itself.
Scope of supply: Dosing unit with 3 nozzles, supply tube, 1 l container, brass pump.
BASIC SPLASH GUARD
via a manually moveable splash guard wall,
installed at the longitudinal side of the clamping plate,
for travel X = 7000 mm.
EXTERNAL ELECTRONIC HAND WHEEL HR 410
switchable to 3 axes

Machine 6278 – RETROFIT 2020 – 2021
The main characteristics of our Universal Milling and Boring Machines and Machining Centers are their quality, their rigidity and consequently their long service life and consequently their stable value. Like everything, our machines, too, are subject to a certain wear. Within the scope of a Retrofit we check particularly stressed components/units, like milling head, spindle headstock and the guideways. Our experts know exactly what to do and rework the corresponding components, and – in extreme cases – they even exchange them, which gives, after a general overhaul – a machine in mint condition, ready to serve for the next 15 – 20 years.
These precise overhauls increase the reliability of the machine, extend the operating life and maintain the (trade-in) value.
