This is a 2023 DN Solutions PUMA 4100LB, a powerful long-bed CNC lathe designed for stable, heavy-duty turning. This particular machine is equipped with an 18-inch chuck, providing strong and secure clamping for large-diameter workpieces. It offers a maximum turning diameter of 550 millimeters and a maximum turning length of 2,092 millimeters, making it ideal for machining long shafts, hydraulic cylinder components, rollers, pipes, and other large industrial parts. The spindle delivers 35 kilowatts of power and up to 2,379 newton-meters of torque. This gives the machine the strength required for heavy material removal and stable cutting under demanding conditions. But one of the most valuable features is the SMW-AUTOBLOK SLU-4-ZS self-centering steady rest. When machining a long workpiece, even a powerful spindle is not enough. Without proper support, the material can bend or vibrate, resulting in chatter, poor surface finish, and dimensional errors. The SLU-4-ZS securely supports the workpiece near the cutting area, helping reduce deflection and maintain consistent accuracy throughout the machining process. Combining a long-bed structure, an 18-inch chuck, powerful spindle torque, and an automatic steady rest, this PUMA 4100LB is ready for serious heavy-duty production. If your company needs a reliable late-model CNC lathe for large and long components, this machine offers the capacity and workholding package you are looking for
