PUMA Series

The PUMA Series is DN Solutions (formerly Doosan Machine Tools) high performance lathe series. Designed for heavy and intermittent cutting, accurate production, and premium surface finishes, this series has a wide variety of models with chuck sizes ranging from 8”-21”, turning lengths up to 120", and options for sub-spindles, y-axis, and milling capabilities. This Series has a box guideway structure which prevents vibration and gives it secure dynamic rigidity. It has the highest spindle speed in its class and also delivers powerful cutting capabilities.

Unmatched Rigidity and Capacity for Large Component Machining

The DN Solutions PUMA 1000A High Performance Turning Center is specifically engineered to meet the challenges associated with machining large, heavy components. This machine’s design ensures long-term high accuracy and superior surface finishes, consistently performing through heavy and interrupted cutting cycles. Its structural integrity is derived from a one-piece 45-degree torque-tube slant bed manufactured using Meehanite® casting, which actively inhibits thermal deformation and twisting while providing excellent vibration dampening characteristics. The PUMA 1000A accommodates substantial workpieces, offering a maximum turning diameter of 1,000 mm (39.4 in) and an extensive maximum turning length of 2,040 mm (80.3 in). Furthermore, the large 236.5 mm (9.31 in) draw tube ID supports demanding throughput requirements for large shafts.

High-Torque Spindle Drive for Aggressive Material Removal

The PUMA 1000A is equipped with a powerful drivetrain necessary for heavy stock removal, effectively reducing the number of required roughing passes. This is achieved by a robust 75 kW (100 hp) AC spindle motor that delivers an exceptional maximum spindle torque of 11,011 Nm (8,121 ft-lb). Crucially for heavy turning operations, full power is accessible starting from 65 rpm. Beyond cutting power, the machine is optimized to minimize non-cutting time through rapid axis movement: the Z-axis achieves a fast rapid traverse rate of 16 m/min (630 ipm). Enhanced axis performance is further demonstrated by the Z-axis, which is capable of producing up to 38,975 N (8,762 lb) of thrust for reliable heavy feeding.

Engineered Precision: Solid Box Way Construction and Advanced Turret Design

The PUMA 1000A integrates ultra-rigid construction with classic manufacturing techniques, featuring solid box way construction to ensure secure dynamic rigidity and prevent vibration. All guideways are wide wrap-around rectangular types, which are induction hardened and precision ground for long-term accuracy and stability. A key feature enhancing durability is the application of a Fluoroplastic resin bonded to mating way surfaces, a material that virtually eliminates guideway wear and provides vibration dampening for superior surface finishes. The 10-station servo turret is built for extreme rigidity, utilizing a large 450 mm (17.7") diameter Curvic coupling and generating 222 kN (49,900 lb) of hydraulic clamp force. This heavy-duty system supports demanding operations like long boring bar overhangs, ensuring indexing repeatability of ±0.0005 degree and a rapid 0.31-second index time.

Integrated Control and Operational Efficiency

Operational efficiency is maximized through the integration of the FANUC 0i-Plus control featuring the iHMi touch screen interface. Programming time is minimized by the inclusion of EZ Guide i Conversational Programming, which allows users to program and run the machine directly on the shop floor using friendly dialogue menus for common cycle functions such as roughing, grooving, and threading. The system also incorporates the Easy Operation Package (EOP), which provides essential functions for setup and maintenance. This package includes a Tool Load Monitoring System, allowing high and low limits to be set for each tool to trigger alarms, tool changes, or machine shutdown based on wear and breakage settings. The machine also includes advanced features such as programmable high/low chucking pressure for optimizing clamping on double-sided or thin-walled parts.

The PUMA 1000A is designed for high-performance industrial applications across sectors like Automotive, Aerospace, and Energy.
