Used DOOSAN DOOTURN 4 CNC LATHE for sale — CNC Turning Centers

The DOOSAN DOOTURN 4 is a highly capable CNC turning center belonging to the slant bed machine class, designed to provide rigid, stable, and precise machining for medium-to-large industrial components. Engineered for demanding production environments, this model is configured to handle heavy metal removal while maintaining precision over extended run times. At the heart of this machine is the Fanuc OT CNC control system, paired with Alpha Drives, which delivers reliable axis control and efficient programming for operators. The structural configuration of the DOOTURN 4 features a maximum swing of 579.88 mm, allowing for the clearance of larger workpieces. It accommodates a maximum turning diameter of 389.89 mm and a maximum turning length of up to 730 mm. This work envelope is managed through precise axis travels, with the X-axis providing 245.11 mm of travel and the Z-axis offering 750.06 mm of travel. The Z-axis is capable of a rapid traverse rate of 787 IPM, ensuring minimized non-cutting time during cycles. Workholding and spindle performance are optimized for demanding material removal. The machine is outfitted with a large 300 mm chuck mounted on an A2-8 spindle nose. The spindle itself is driven by a powerful 22.37 kW motor, operating across a speed range from 40 to 3500 RPM. This configuration supports a generous spindle bore of 101.6 mm, which translates to a maximum bar capacity of 95.25 mm, enabling efficient processing of raw bar stock. Tool management is handled by a robust 12-station turret. This system facilitates versatile tooling arrays and features a turret index time of 1.5 seconds to optimize operational efficiency. For shaft work and extended workpieces, the DOOTURN 4 includes a heavy-duty tailstock featuring an MT-4 taper, a quill travel of 101.6 mm, and a quill diameter of 101.6 mm, which provides rigid support to prevent workpiece deflection during machining. Based on these specifications, this CNC turning center is well-suited for a variety of industrial applications, including the machining of shafts, heavy flanges, and high-tolerance components for the automotive, energy, and general engineering sectors. This machine is offered in used condition, having been imported and thoroughly inspected to ensure its operational integrity. It is available from Corel Machinery in India, and we facilitate complete packing, logistics, and secure worldwide shipping to your facility.
