SEIBU SNC-20HPI CNC LATHE

Technical Description

This is a 2-axis CNC turning center designed for precision lathe operations on cylindrical workpieces. Equipped with a 3.94-inch chuck, the machine accommodates parts with moderate diameters suitable for small to mid-range production runs. The system operates on a 2.2 kW spindle motor, providing adequate power for general turning, threading, and facing operations across various materials including steel, aluminum, and cast iron. The machine reaches a maximum spindle speed of 10,000 RPM, enabling high-speed finishing cuts and improved surface quality on smaller diameter workpieces. The dual-axis configuration allows simultaneous control of the X-axis (radial) and Z-axis (longitudinal) movements, enabling the creation of complex turned features, tapers, and grooves within the machine's working envelope. This axis arrangement is fundamental to lathe operations, allowing precise positioning relative to the rotating workpiece. Control is managed through a FANUC 21i-T CNC control system, a widely-recognized industrial controller offering reliable programming capabilities, automatic tool offset compensation, and real-time spindle speed regulation. The FANUC controller provides intuitive operator interfaces and supports standard G-code programming for reproducible, efficient machining cycles. This 2-axis configuration represents the standard for traditional CNC lathe operations, distinguishing it from more complex multi-axis systems while maintaining the precision and repeatability required for production environments. The combination of moderate spindle power, respectable RPM capacity, and proven FANUC control makes this machine suitable for general job shop work and small-batch component manufacturing across diverse industries.
