AMERA SEIKI S-40/3M CNC LATHE

Technical Description

This heavy-duty CNC turning center represents a significant industrial machine tool designed for large-scale precision machining operations. With a 40-inch chuck capacity and a maximum turning diameter of 33.5 inches, the machine accommodates substantial workpieces while maintaining dimensional accuracy through its rigid construction. The 39.72-inch swing diameter provides adequate clearance for complex turned geometries and multi-axis operations. The machine features an extended 118-inch machining length, enabling production of lengthy components without requiring secondary operations or repositioning. This substantial Z-axis travel minimizes setup time and reduces potential for tolerance stack-up errors, making it ideal for aerospace and automotive applications requiring IT5-IT8 tolerance levels. The 50 hp drive system delivers sufficient power and torque for continuous heavy-duty cutting operations across diverse material types. The CNC control architecture enables multi-axis functionality with automated tool turret systems, typically featuring 12 to 24 tool positions. This allows for integrated turning, boring, drilling, threading, and milling operations in a single setup, significantly reducing part cycle times. Advanced spindle dynamics and inherent machine rigidity ensure surface finishes approaching Ra 0.8-1.6 μm for standard precision turning applications. The combination of robust guideways, linear motion systems, and a powerful spindle ensures repeatability within ±0.0025 mm tolerances. This configuration makes the machine suitable for producing complex, high-precision components in demanding industries requiring uncompromised accuracy and reliability.
