SEIBU SNC-35HPI CNC LATHES

Technical Description

This high-performance CNC spindle axis is designed for precision machining applications, featuring a robust 3.7 kW motor capable of reaching a maximum speed of 10,000 RPM. Engineered for dynamic responsiveness and accuracy, the axis delivers consistent torque and smooth operation across a wide speed range, making it suitable for demanding milling and turning tasks. The system is fully integrated with a FANUC 21i-T CNC control, providing advanced programmability, reliable servo management, and seamless communication with machine peripherals. The FANUC 21i-T controller supports comprehensive parameter configuration for axis tuning, including soft limit settings (parameters 1320, 1321), reference position return, and APC alarm management for absolute pulse coders. Communication and I/O settings are optimized for efficient data transfer, with standard RS232 interface support, configurable baud rates (including 9600 bps), and handshaking protocols. The axis utilizes absolute encoders for precise position feedback, ensuring accurate homing and repeatability. The FANUC control enables easy setup and diagnostics, with dedicated screens for parameter write, system configuration, and alarm handling. Safety features include constant surface speed control and configurable maximum spindle speed limits to prevent over-speed conditions. The system is designed for compatibility with a wide range of tooling and workholding solutions, supporting both manual and automated operation modes. With its high power, speed, and advanced CNC integration, this axis delivers reliable, high-precision performance for modern CNC machining environments.
