USED DOOSAN PUMA 400B – 2011

The DOOSAN PUMA 400B – 2011 is a heavy-duty CNC horizontal turning center designed for machining large-diameter and heavy industrial components. The PUMA 400B is part of Doosan’s PUMA series of production lathes and is built around a rigid machine structure, large spindle, powerful drive system, and substantial turning capacity.

The machine is designed for applications requiring aggressive material removal and stable cutting of steel, cast iron, stainless steel, and other difficult materials. Its large spindle bore and heavy-duty chucking capability make it suitable for components that cannot be accommodated on conventional mid-size CNC lathes.

A typical PUMA 400B configuration provides approximately 23.6 inches of swing over the bed, with a maximum turning diameter around 22 inches, depending on the exact configuration. The machine can be equipped with a large hydraulic chuck, automatic turret, programmable tailstock, chip conveyor, coolant system, and other production accessories.

The 2011 PUMA 400B is particularly suited for oil and gas, energy, construction equipment, mining, heavy machinery, automotive, defense, and general industrial manufacturing. It can perform turning, facing, boring, threading, grooving, drilling, and other operations on large workpieces.

WHY CHOOSE DOOSAN PUMA 400B

The primary advantage of the DOOSAN PUMA 400B is its combination of large workpiece capacity, heavy-duty construction, high spindle torque, and substantial spindle bore. It is designed for applications where cutting forces and component size exceed the capabilities of smaller production lathes.

The large spindle and hydraulic chuck provide a solid workholding platform, while the programmable tailstock allows long components to be supported during machining. This is particularly important when machining shafts, rollers, and other long or heavy parts.

The PUMA 400B is also well suited for job shops because it can handle a wide range of materials and component sizes while using conventional CNC turning tools and workholding.

WHY BUY USED DOOSAN PUMA 400B – 2011

A used 2011 DOOSAN PUMA 400B can provide substantial heavy-turning capacity at a significantly lower investment than a new large CNC turning center.

When evaluating a used PUMA 400B, inspect the spindle bearings, spindle bore, chuck, turret, ballscrews, linear guideways, tailstock, hydraulic system, coolant system, and CNC control.

Buyers should verify spindle hours, spindle runout, chuck clamping pressure, turret indexing accuracy, axis backlash, tailstock alignment, machine geometry, and maintenance records.

A machine equipped with a large hydraulic chuck, programmable tailstock, steady rest, chip conveyor, high-pressure coolant, tooling package, and bar feeder can provide considerably more production value.
