Doosan PUMA 700M

The M designation on the PUMA 700M indicates milling capability — the machine is equipped with driven (live) tooling in the turret, enabling rotary cutting tools such as end mills, drills, and taps to operate while the main spindle is stationary or indexing. This allows milling of cross-holes, keyways, flat surfaces, and other non-turned features on large workpieces without moving the part to a machining center. The M variant is distinguished from the base PUMA 700 turning-only model.

The PUMA 700M has a maximum swing over the bed of 700mm, giving a maximum turning radius of 350mm. The maximum turning diameter (over the cross-slide) is typically 630mm in standard configuration. Very large flanged parts may be limited by cross-slide clearance. Shops machining parts near the maximum diameter limit should provide workpiece drawings to DN Solutions applications engineers to verify clearances and confirm the machine is appropriate for their specific part geometry.

The PUMA 700M requires a reinforced concrete foundation appropriate for its weight class — approximately 30,000 kg for standard bed configurations, heavier for long-bed variants. Foundation drawings are provided by DN Solutions during the installation planning phase. Shops should also verify floor load ratings, ceiling height for overhead crane access during part loading, and power supply requirements (typically 50–60 kVA three-phase) well before machine delivery. DN Solutions installation engineers coordinate foundation specifications during the pre-installation process.

Due to the size and weight of workpieces machined on the PUMA 700M, overhead bridge crane loading is the standard method. The machine's full enclosure includes large access doors sized for crane-assisted workpiece entry. Floor-mounted lifting fixtures, tailstock support for long shaft work, and steady rest options for large-diameter shafts are all available. Shops without existing overhead crane capacity should plan crane infrastructure alongside the machine investment.

Both machines compete in the large heavy-duty turning segment targeting energy, marine, and industrial heavy component manufacturing. The Okuma LT3000 runs the Okuma OSP control with Okuma's Thermal Friendly Concept thermal compensation, while the PUMA 700M uses Fanuc 0iTPF. Both offer live tooling options and similar swing capacity. Service network differences, control preference, and regional pricing are the primary differentiators. Both are strong choices — the decision often comes down to existing brand relationships and control preference.
