Overview

The Doosan Puma 700 is a large-capacity CNC turning center designed for heavy-duty turning of large diameter and long-length workpieces in the oil and gas, energy, aerospace, shipbuilding, and heavy equipment sectors. The Puma 700 represents the upper end of Doosan's Puma turning center line, providing a swing diameter and between-centers capacity suited for large shafts, flanges, rings, and sleeves that standard production turning centers cannot accommodate. With a maximum swing over the bed of approximately 800 mm and up to 3,000 mm between centers in extended configurations, the Puma 700 is a purpose-built machine for large-part turning that smaller lathes cannot address.

Doosan engineers the Puma 700 on a heavily-reinforced box-way bed structure in cast iron, providing the damping and rigidity essential for interrupted turning, large overhang roughing, and hard turning of large workpieces in difficult materials. The bed is thermally-symmetric in cross-section to minimize thermal bowing during sustained cutting, maintaining geometric accuracy as the machine heats during a production shift. Doosan's Puma 700 headstock carries a large-bore spindle with direct-drive or gear-drive options depending on the torque and speed requirements of the configured application: oil field drill collar turning requires very high torque at low RPM, while ring-rolling blank facing may need a more balanced speed/torque profile.

The turret on the Puma 700 is a 12-station VDI or BOT-type turret accommodating large-shank turning tools and driven tooling in milling configurations (Puma 700M variant). Driven tool capability enables OD turning, facing, and boring operations to be combined with cross-drilling, milling of keyways, flats, and radial features in a single chucking — particularly valuable for large shaft and flange components where repositioning to a VMC for secondary milling operations is both time-consuming and creates alignment challenges with large, heavy workpieces.

Doosan's global aftermarket support infrastructure through DN Solutions provides local service coverage for the Puma 700 in all major industrial markets — a meaningful factor for heavy industry customers who cannot tolerate extended machine downtime waiting for remote service response. Spare parts for the Puma 700's major components (spindle bearings, turret drive, hydraulic chuck components) are maintained in regional warehouses. Application engineering support for programming large-diameter turning operations, including workholding for long shafts and large-diameter chucking of rings and flanges, is available through the Doosan distributor network.

Pricing for the Doosan Puma 700 in standard 2-axis turning configuration ranges from approximately $350,000 to $550,000 depending on bed length, spindle specification, driven tooling, and control. The Puma 700M with driven tooling is priced higher, typically $450,000 to $680,000. This positions the machine competitively against equivalent Okuma LB3000 EX, Mazak Nexus 700, and Hwacheon Hi-TECH 700 at comparable capacity.

Strengths & Limitations

Strengths

800 mm swing over bed and 700 mm maximum turning diameter handle the large flanges, rings, sleeves, and shaft components in oil and gas, energy, and heavy equipment that standard production lathes cannot accommodate
4,500 Nm peak spindle torque is appropriate for aggressive roughing of large-diameter forgings and castings in steel alloy, stainless, and duplex grades common in oil field and energy sector components
Box-way bed construction provides the cutting damping and rigidity required for large-diameter interrupted cuts, hard turning of heat-treated shafts, and long overhang boring of deep bores common in large workpiece turning
Doosan's DN Solutions global service network with regional parts warehousing and factory-trained technicians reduces the downtime risk associated with large-machine breakdown in industries where unplanned outage costs are high
Puma 700M variant with 12-station driven tooling turret combines turning and milling capability to complete shaft and flange components with keyways, cross-holes, and radial features in a single chucking, eliminating VMC transfer setups

Limitations

800 RPM maximum spindle speed (1,200 RPM optional) limits surface finishing speed on small-diameter sections of large shafts — applications with small-diameter turned features on large shaft components may see compromised cycle times or surface finish quality on the small-diameter features
28,000 kg machine weight and large floor footprint require a purpose-designed installation site with reinforced concrete foundation, large crane access, and leveling capability beyond what standard shop facilities provide — significant installation planning required
$350K–$680K investment range requires clear volume justification — shops with occasional large-diameter turning requirements may find it more economical to subcontract large turning work than to maintain the Puma 700 in-house

Best For

Oil and gas equipment manufacturers and service companies producing drill collars, stabilizers, large valve bodies, and wellhead components requiring large swing, high torque, and long between-centers turning capacity Energy sector suppliers machining large flanges, pipe fittings, pressure vessel components, and turbine ring segments in stainless alloy and duplex steel where workpiece diameter and weight class require a dedicated large-capacity lathe Heavy equipment and mining machinery manufacturers producing large axles, drive shafts, bearing housings, and sprocket hubs in alloy steel where turning capacity exceeds standard production lathe limits Aerospace maintenance, repair, and overhaul (MRO) shops refurbishing large landing gear components, engine shafts, and structural forgings requiring precision turning of large-diameter, long-length workpieces in titanium and high-strength steel

Frequently Asked Questions

01 What is the difference between the Doosan Puma 700 and Puma 700M?

The Puma 700 is a standard 2-axis turning center with a non-driven 12-station turret for turning, boring, drilling, and threading operations only. The Puma 700M adds driven tooling capability to the turret, enabling live milling of keyways, flats, slots, cross-holes, and other milled features that would otherwise require a separate VMC setup. The 700M typically also includes a C-axis (spindle position control) enabling the spindle to be used as a positioning axis for milling operations. The 700M's additional capability commands a $100,000–$130,000 premium over the standard Puma 700.

02 What chuck sizes are compatible with the Doosan Puma 700?

The Puma 700 spindle nose is sized for large-diameter chuck mounting, typically accepting 500–630 mm diameter 3-jaw and 4-jaw hydraulic chucks for large-diameter workholding. Custom jaw configurations for non-standard flange, ring, and irregular cross-section workpieces are available from workholding suppliers. For very large diameter chucking above 630 mm, face plate and strap-clamp setups are used with the machine's face plate drive configuration. Steady rests for long shaft support between headstock and tailstock are available in multiple diameter capacities matched to the Puma 700's swing dimension.

03 Can the Puma 700 perform hard turning of heat-treated components?

Yes. Hard turning of components in the 45–62 HRC hardness range is practical on the Puma 700 with CBN (cubic boron nitride) inserts in rigid SECO, Kennametal, or Iscar tooling systems. The box-way construction provides the cutting damping required to suppress chatter in hard turning — a rigid platform requirement for CBN cutting, which is brittle and cannot tolerate vibration-induced insert fracture. Oil field down-hole tool components in hard alloy steel are a documented application. Key parameters: light depths of cut (0.1–0.3 mm), moderate feed rates, dry cutting or light mist, and rigid toolholder with minimum overhang.

04 Is a steady rest available for long shaft machining on the Puma 700?

Yes. Doosan offers both fixed (floor-mounted) and traveling steady rests for the Puma 700 in configurations matched to the machine's between-centers capacity and swing diameter. The traveling steady rest follows the carriage along the Z axis, providing continuous workpiece support adjacent to the cutting zone — particularly important for long shafts where workpiece deflection under cutting forces would otherwise cause diameter variation along the shaft length. Fixed steady rests at the workpiece midpoint are used for shafts where support at a fixed intermediate point adequately controls deflection. Both options are available as factory-installed or field-installed accessories.

05 What oil and gas standards are relevant to the Puma 700's applications?

Oil and gas components machined on the Puma 700 typically fall under API (American Petroleum Institute) standards including API 5CT (casing and tubing), API 5DP (drill pipe), API 7-1 (drill bits and rotary components), and API 11B (sucker rods). These standards define dimensional tolerances, material specifications, and thread form requirements for downhole components. The Puma 700's turning capability, threading cycles in the Fanuc control, and accuracy specifications are appropriate for producing API-compliant thread forms (API buttress, API round, VAM, and proprietary premium connections) to the tolerances these standards require.
