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 3100 a Standout Turning Center?

Engineered for long-term accuracy, surface quality, and power.

The DN Solutions PUMA 3100 delivers exceptional rigidity and precision for heavy-duty applications. Designed with a 30-degree slant-bed casting and box-way construction, it maintains stability under full load while providing smooth axis movement for superior finishes. A 30 HP digital AC spindle motor reaches 2,800 RPM, enabling powerful roughing and high-speed finishing. Combined with a 10-station servo turret, FANUC 0i-Plus control, and EZ Guide i programming, it’s ideal for production shops that demand accuracy and efficiency.

Key Highlights

2,800 RPM main spindle (828 ft-lb torque)
20.67″ max turning diameter × 29.9″ max turning length
1,181 IPM rapid traverse for reduced non-cutting time
Rigid box-way construction and torque-detection protection
FANUC 0i-Plus control with 15″ iHMi touchscreen and EZ Guide i

How Is the PUMA 3100 Built for Accuracy and Longevity?

Rigidity, thermal stability, and operator-friendly design.

The Meehanite® cast-iron bed provides fine-grain density for maximum vibration dampening and reduced thermal distortion. All guideways are induction-hardened rectangular box ways with bonded resin for low friction and long-term accuracy. The unexpected disturbance torque detection system protects the axis and ball screws by instantly reversing servos upon overload, minimizing downtime.

One-piece slant-bed with 30° angle for chip flow and operator ergonomics
± 0.00008″ X-axis / ± 0.00012″ Z-axis repeatability
Servo-driven tailstock and automatic lubrication system for reliability

What Smart Technologies Improve Usability?

FANUC 0i-Plus with iHMi touchscreen for intuitive control.

The FANUC 0i-Plus system offers conversational EZ Guide i programming, enabling operators to create cycles for roughing, threading, and drilling directly at the machine. The 15″ iHMi panel integrates real-time load monitoring, alarm guidance, and tool management. Features like Tool Load Monitor, automatic offset input, and multi-language display simplify operation and reduce training time.

Control Features

Hybrid conversational + G-code programming
2 MB part storage / 1,000 program capacity
Tool life and wear management
Graphical toolpath simulation and canned-cycle assist
USB and Ethernet connectivity

How Does the Cooling and Thermal System Support Accuracy?

Heat isolation, coolant design, and chip management enhance repeatability.

A 65 PSI multi-stage coolant pump delivers high-flow coolant directly through the turret, ensuring consistent chip removal and temperature control. The coolant tank is roller-mounted and separated from the bed to prevent heat transfer. Optional 145 PSI and 1,000 PSI high-pressure systems enable deep drilling and improved surface finish. Built-in heat exhaust fans, isolation covers, and auto light-off mode further reduce heat buildup inside the enclosure.
