AMERA SEIKI S-40/4M CNC LATHE

Technical Description

This CNC turning center represents a heavy-duty precision lathe engineered for large-scale industrial machining operations. The machine features a substantial 40-inch chuck capacity paired with a 33.5-inch maximum turning diameter and 39.72-inch swing over bed, accommodating workpieces of considerable size and weight. The extended 157-inch machining length enables production of lengthy cylindrical components, making it suitable for shafts, tubes, and similar applications requiring substantial axial travel. Powered by a robust 50 hp motor, this machine delivers sufficient torque and cutting force for demanding turning operations on ferrous and non-ferrous materials. The CNC control system provides automated tool selection, positioning, and operation across multiple axes, ensuring repeatability and precision that manual lathes cannot achieve. CNC turning centers of this class typically achieve tolerances up to ±0.0001 inches (±0.0025 mm), significantly exceeding manual turning capabilities. The machine is equipped with an automated tool turret facilitating rapid tool changes and complex multi-operation cycles without manual intervention. This configuration minimizes setup time and reduces the potential for dimensional errors caused by workpiece repositioning. The combination of high spindle power, extended working envelope, and computerized control makes this machine ideal for aerospace, automotive, and heavy industrial applications where precision, efficiency, and production volume are critical requirements.
