Big machines from Mills are powerful, accurate, fast and flexible

Mills CNC, the exclusive distributor of DN Solutions’ (formerly 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 DN Solutions’ 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 six different 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 4,070mm.

SMX 5100LS and SMX 5100LSB machines are equipped with high-torque, built-in (left and right) spindles (up to 37kW/2,400rpm) with 0.0001° resolution on their C-axes for high precision contouring. SMX5100L, SMX 5100LB, SMX 5100XL and SMX 5100XLB models feature programmable, servo-driven tailstocks (instead of sub-spindles) for the precision machining of long shafts and tubes.

All six models are supplied with a powerful and versatile B-axis milling head (±120° stroke) that features the Capto C8 quick-change tooling system powered by a 37kW motor rotating at 10,000rpm. The roller gear cam mechanism that drives the B-axis eliminates backlash and is highly rigid, capable of outputting torque up to 4,200Nm.

SMX 5100L machines’ productivity and performance are further optimised by their ultra-fast 40m/minute rapid rates, their 520mm Y-axis capability and their heavy-duty high-precision roller LM guideways.

The machines are also equipped with generous sized, servo-driven tool changers capable of housing up to 120 tools, with the machines’ ATCs also having their own touchscreen operation panel for ease of use, efficient job set-ups and improved process reliability. Long boring bar and tool magazines are also available as options that further extend the machines’ application potential.

From their rigid design and build, and sealed guideways that prevent chip and coolant ingress through to their spindle, headstock and ballscrew cooling systems that keep thermal deformation under check, SMX 5100L machines deliver consistently reliable 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 – DN Solutions’ new, 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) to improve performance and efficiency.

“From their size and capacity, right through to their speed, power, accuracy and versatility, everything about the new SMX 5100L multi-tasking mill-turn machines is impressive,” enthuses Tony Dale, Mills CNC’s CEO.

“Although only recently launched into the market, we believe that the new SMX 5100L machines will become immensely popular and successful.”
