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.

What Makes the PUMA 2600SY II a Standout Turning Center?

Power, precision, and complete part machining in one setup.

The DN Solutions PUMA 2600SY II combines Y-axis milling, C-axis contouring, and a sub spindle to complete complex parts in a single setup. This reduces cycle times and eliminates costly secondary operations. A 30° slant Meehanite® bed ensures long-term rigidity, while dual integral spindle motors power both the main and sub spindles for faster acceleration and better surface finishes.

Highlights

Dual integral spindles (main: 30 HP / 4,000 RPM, sub: 20 HP / 6,000 RPM)
Y-axis ±2.065″ for off-center milling and drilling
12-station BMT-65 turret with 24 index positions
Live tooling with 5,000 RPM and 10 HP rotary motor
Thermal compensation and glass scales for accuracy

How Is the PUMA 2600SY II Designed for Productivity and Precision?

Every element of construction enhances stability, accuracy, and surface finish.

The one-piece cast-iron slant bed absorbs vibration and improves thermal stability. Wide wrap-around NTN box guideways and dual-supported ball screws ensure rigidity under heavy loads. The integral main spindle eliminates belts, preventing vibration and backlash, while a servo-driven turret enables bi-directional indexing in just 0.15 seconds.

Structural Highlights

230 mm curvic coupling and 59 kN turret clamping force
Synchronized main and sub spindles for part transfer at 4,000 RPM
Meehanite® cast bed for superior vibration damping
Torque detection system protects axis drives in collision events

How Does the Control System Simplify Machining?

FANUC 0i-Plus with iHMi touchscreen puts precision in the operator’s hands.

The integrated FANUC 0i-Plus control provides a 15″ touchscreen with EZ Guide i conversational programming for fast setups and live cycle previews. Operators can mix G-code with pattern cycles, monitor tool wear, and adjust offsets dynamically. The Tool Load Monitoring System automatically stops the machine to prevent tool damage.

Smart Control Capabilities

Conversational and G-code hybrid programming
Real-time spindle and axis load monitoring
Tool life management and automatic offset input
Ethernet, USB, and RS-232C connectivity
Built-in alarm library and cycle assist graphics

Why Choose the PUMA 2600SY II for Complex Machining?

Complete part machining from both ends with exceptional accuracy.

The Y-axis and sub spindle configuration makes this machine ideal for multi-process parts — turning, milling, drilling, and tapping from both sides. Polar coordinate interpolation, helical milling, and rigid tapping are standard, enabling simultaneous control across five axes (X/Y/Z/C/B). The Preci-Flex® tooling system enhances setup repeatability for live tooling applications.

FAQ Section

How does the sub spindle improve productivity?

The 6,000 RPM sub spindle allows back-side machining without repositioning, enabling complete parts in one setup and reducing handling time.

What keeps accuracy stable during long runs?

Thermal compensation sensors, glass scales, and heat isolation panels automatically adjust axis movement to maintain micron-level precision.

Is the machine suitable for heavy cutting?

Yes. The rigid bed, box-way design, and dual integral spindles deliver the torque and stability required for deep cuts and long tool overhangs.

Can it handle complex part geometries?

Absolutely. With Y-axis motion, full contouring C-axis, and live tooling on all stations, it supports off-center milling, keyway cutting, and drilling.

Does Ellison Technologies provide installation and service?

Yes. Ellison offers installation, training, and ongoing support within our regional service areas, ensuring long-term machine reliability.
