The machine is built with a rigid cast iron structure and heavy-duty box guideway construction to withstand aggressive cutting forces while maintaining excellent thermal stability and long-term accuracy. The extended bed design provides significantly greater Z-axis travel and turning length compared with standard turning centers, making the PUMA 3100LSY ideal for producing long shafts, cylinders, rollers, hydraulic components, and other elongated parts.

The DN SOLUTIONS PUMA 3100LSY is typically equipped with a FANUC CNC control system that offers advanced turning and milling cycles, intuitive programming, tool management functions, and machine diagnostics. Its servo-driven BMT live tooling turret provides excellent rigidity and superior milling performance compared with conventional turret designs. Optional equipment such as high-pressure coolant systems, automatic chip conveyors, programmable tailstocks, steady rests, bar feeders, parts catchers, and robotic loading systems can further enhance the machine’s productivity and support automated manufacturing.

Industries including aerospace, oil and gas, automotive, defense, energy, agricultural equipment, heavy machinery, and general contract manufacturing commonly rely on the PUMA 3100LSY for producing high-precision components. Typical applications include drive shafts, hydraulic cylinders, pump shafts, valve bodies, aerospace fittings, couplings, rollers, connectors, and complex mechanical parts requiring both turning and off-center milling operations.

The used CNC machine market continues to show strong demand for the DN SOLUTIONS PUMA 3100LSY because it offers the versatility of a mill-turn machining system with the capacity of a long-bed turning center. Purchasing a used PUMA 3100LSY allows manufacturers to gain access to advanced Y-axis machining technology at a considerably lower cost than purchasing a new machine.
