USED DN SOLUTIONS PUMA 3100SY

The DN SOLUTIONS PUMA 3100SY is a high-performance CNC turning center designed with a sub-spindle, Y-axis capability, and live tooling technology to provide complete multi-tasking machining in a single setup. As part of the advanced PUMA 2100/2600/3100 series from DN SOLUTIONS, formerly known as Doosan Machine Tools, the PUMA 3100SY combines the strength of a heavy-duty CNC lathe with the flexibility of milling, drilling, tapping, and secondary spindle operations. This advanced machine is engineered to maximize productivity, reduce cycle times, and produce highly complex components with exceptional accuracy.

Unlike traditional CNC lathes that require multiple machines and setups to complete a component, the PUMA 3100SY integrates a main spindle, sub-spindle, C-axis positioning, Y-axis movement, and a live tooling turret. This configuration enables complete machining of both the front and back sides of a component in a single cycle. Parts can be transferred automatically from the main spindle to the sub-spindle, eliminating manual handling, improving concentricity, and reducing overall manufacturing time.

The machine is built with a rigid cast iron structure and heavy-duty box guideway construction designed to maintain stability during aggressive roughing and precision finishing operations. Its powerful spindle systems provide excellent torque and cutting performance across a wide range of materials including stainless steel, alloy steel, titanium, aluminum, brass, cast iron, and exotic alloys. The robust construction and precision engineering make the PUMA 3100SY suitable for continuous production environments requiring consistent accuracy and reliability.

Most DN SOLUTIONS PUMA 3100SY machines are equipped with advanced FANUC CNC controls that provide powerful programming functions, synchronized spindle operations, turning and milling cycles, tool management, and machine diagnostics. The rigid BMT live tooling turret provides excellent milling performance, while the Y-axis enables off-center machining such as cross holes, slots, pockets, and complex contours. Optional equipment such as high-pressure coolant systems, automatic chip conveyors, bar feeders, parts catchers, and robotic automation further increase productivity.

The DN SOLUTIONS PUMA 3100SY is widely used in aerospace, automotive, medical, defense, oil and gas, electronics, hydraulic systems, and general precision manufacturing. Typical components include valve bodies, aerospace fittings, hydraulic manifolds, shafts, connectors, couplings, medical implants, pump components, and other complex parts requiring complete machining from multiple sides.

The popularity of the used DN SOLUTIONS PUMA 3100SY remains strong because it provides advanced multi-tasking capabilities at a significantly lower investment than purchasing a new machine. With its combination of dual spindle technology, Y-axis flexibility, live tooling, and proven PUMA-series durability, the machine offers excellent value for manufacturers seeking increased efficiency and reduced production costs.
