Mills CNC introduces new
mill-turn machines.
Mills CNC, the exclusive distributor of
Doosan machine tools in the UK and
Ireland, has introduced a new range of
large-capacity, multi-tasking mill-turn
machines into the market.
The Puma SMX 5100L series, the
largest in Doosan’s SMX range, has
been designed and built to handle large,
heavy workpieces typically found in the
aerospace, energy and oil and gas sectors
- and machine them to completion in a
single set-up.
There are four diff erent models in
the SMX 5100L range with the largest
machines having chuck sizes up to 21”, a
maximum turning diameter of 830mm and
a maximum turning length of 3050mm.
SMX 5100LS and SMX 5100LSB
machines are equipped with high-torque,
built-in (left and right) spindles (up to
37kW/2400rpm) with 0.0001° resolution
on their C-axes for high precision
contouring. SMX5100L and SMX 5100LB
models feature a programmable, servodriven
tailstock (instead of a sub-spindle)
for the precision machining of long shafts,
tubes etc.
All four models are supplied with a
powerful and versatile B-axis milling head
(+/- 120° stroke) that features the Capto
C8 quick-change tooling system and is
powered by a 37kW motor that rotates at
10,000rpm. The roller gear cam mechanism
that drives the B-axis eliminates backlash
and is highly rigid, capable of outputting
torque of up to 2700N-m.
SMX 5100L machines’ productivity and
performance are further optimised by their

ultra fast rapid rates (40m/min), their
(520mm) Y-axis capability and their heavyduty
high-precision roller LM guideways.
The machines are also equipped with
generous sized, servo-driven tool changers
(up to 120 tools), with the machines’
ATCs also having their own touch screen
operation panel for ease of use, effi cient job
set-ups and improved process reliability.
(Long boring bar and long tool magazines
are also available, as options, that
further extend the machines’ application
potential).
Everything about the new SMX 5100L
machines screams accuracy. From
their rigid design and build and their
sealed guideways (that prevent chip and
coolant ingress) through to their spindle,
headstock and ball-screw cooling systems,
that keep thermal deformation under check
- SMX 5100L machines deliver unrivalled
accuracy even during long machining runs.
SMX 5100L machines are supplied
with the latest CUFOS Fanuc-based
control. CUFOS is an acronym for
Customised User-Friendly Flexible
Operating System - Doosan’s new,
customisable, app-based front-end control
interface that, with a 19” touchscreen and
enhanced 3D graphics, uses conversational
programming software as well as access
to a range of process reliability functions
(like machine collision avoidance etc.), to
improve performance and effi ciency.
Says Tony Dale, Mills CNC’s Technical
Director: “Everything about Doosan’s
new SMX 5100L multi-tasking mill-turn
machines is impressive. From their size
and capacity, right through to their speed,
power, accuracy and versatility. Although
only just launched into the market we
believe that the new SMX 5100L machines
will become immensely popular and
successful.” MADE
