USED DN SOLUTIONS PUMA 3100UL

The DN SOLUTIONS PUMA 3100UL is a heavy-duty long-bed CNC horizontal turning center designed for machining extremely long and large-diameter components with exceptional accuracy, rigidity, and reliability. As part of the advanced PUMA 2100/2600/3100 series from DN SOLUTIONS, formerly known as Doosan Machine Tools, the PUMA 3100UL extends the capabilities of the standard PUMA 3100 platform by offering an extended Z-axis travel and significantly longer turning length. This makes it an ideal solution for manufacturers producing oversized shafts, rollers, cylinders, and other elongated precision components. The PUMA 3100UL features a 12-inch chuck, approximately 21-inch maximum turning diameter, and an impressive 124-inch maximum turning length, making it one of the largest machines in the PUMA 3100 family.

The machine is engineered with a robust cast iron machine structure and heavy-duty box guideway design to provide outstanding vibration absorption and thermal stability during demanding machining applications. Its rigid construction enables aggressive metal removal while maintaining excellent dimensional accuracy and surface finish. The powerful main spindle delivers high torque, allowing the machine to efficiently process difficult materials including alloy steel, stainless steel, cast iron, titanium, aluminum, and other high-performance engineering materials.

Unlike smaller CNC turning centers that are limited by work envelope, the PUMA 3100UL is specifically designed to accommodate extra-long workpieces while maintaining the precision expected from modern CNC equipment. The extended bed design, long Z-axis travel, and large machining capacity allow manufacturers to complete long turning operations without repositioning the workpiece. This reduces setup time, improves concentricity, and ensures greater consistency across production runs.

The DN SOLUTIONS PUMA 3100UL is commonly equipped with a FANUC CNC control system that provides reliable programming, advanced turning cycles, tool management functions, and machine diagnostic capabilities. The machine utilizes a high-rigidity turret system capable of supporting various turning operations including facing, boring, threading, grooving, profiling, and precision finishing. Optional accessories such as programmable tailstocks, steady rests, automatic chip conveyors, high-pressure coolant systems, and automation solutions can further increase productivity and support demanding manufacturing requirements.

Industries including oil and gas, aerospace, power generation, marine, heavy equipment, construction machinery, agricultural equipment, and general precision manufacturing frequently utilize the PUMA 3100UL for large and long components. Typical applications include drive shafts, hydraulic cylinders, rollers, turbine shafts, pump shafts, large couplings, threaded shafts, and custom industrial parts.

The used CNC machine market continues to show strong demand for the DN SOLUTIONS PUMA 3100UL because it offers large-capacity machining, exceptional durability, and proven long-term reliability at a considerably lower investment compared with purchasing a new machine. Its combination of extended turning capacity, heavy-duty construction, and advanced CNC technology makes it an excellent choice for manufacturers looking to expand long-part machining capabilities.
