USED DN SOLUTIONS PUMA 3100M

The DN SOLUTIONS PUMA 3100M is a powerful CNC turning center with integrated live tooling capability, designed for manufacturers that require the efficiency of completing turning and secondary machining operations within a single setup. As part of the advanced PUMA 2100/2600/3100 series from DN SOLUTIONS, formerly known as Doosan Machine Tools, the PUMA 3100M combines the strength and rigidity of a heavy-duty CNC lathe with the flexibility of milling, drilling, and tapping capabilities. The machine is built to deliver high productivity, precision, and reliability in demanding industrial environments. The PUMA 3100M features a 12-inch chuck, approximately 17-inch maximum turning diameter, 30-inch turning length, and a powerful spindle system, making it ideal for medium to large precision components.

Unlike conventional 2-axis CNC lathes that are limited to basic turning functions, the PUMA 3100M incorporates C-axis spindle positioning and a live tooling turret, allowing multiple machining operations to be completed without transferring the workpiece to another machine. Cross drilling, tapping, milling flats, slot cutting, and other complex features can be produced in the same setup, reducing cycle times, improving accuracy, and increasing overall manufacturing efficiency.

The machine is built around a rigid cast iron structure designed to minimize vibration and maintain thermal stability during aggressive cutting operations. Its heavy-duty spindle provides excellent torque for machining challenging materials such as stainless steel, alloy steel, titanium, aluminum, cast iron, and other engineering materials. The robust construction makes the PUMA 3100M suitable for both heavy roughing and high-precision finishing applications.

Most DN SOLUTIONS PUMA 3100M machines are equipped with a FANUC CNC control system, offering reliable operation, advanced turning cycles, efficient programming, and comprehensive diagnostic features. The servo-driven live tooling turret provides rapid indexing and excellent rigidity, allowing manufacturers to maximize productivity while maintaining tight tolerances and superior surface finishes.

Industries including aerospace, automotive, oil and gas, energy, defense, agricultural equipment, heavy machinery, and general contract manufacturing commonly use the PUMA 3100M for producing precision parts. Typical components include valve bodies, hydraulic components, shafts, couplings, pump parts, flanges, bearing housings, connectors, and custom-machined industrial components.

The used CNC machine market continues to show strong demand for the DN SOLUTIONS PUMA 3100M because it offers the advantages of a multi-tasking turning center at a significantly lower investment compared with purchasing new equipment. Its combination of a powerful spindle, live tooling capability, rigid construction, and proven reliability makes it an excellent investment for machine shops seeking to expand their manufacturing capabilities.
