SEIBU SNC-20HPISP CNC LATHE

Technical Description

The FANUC 21iT CNC lathe represents a compact turning solution engineered for precision machining applications. This control system operates with 2 simultaneous control axes, enabling circular interpolation for complex contour work and linear positioning capabilities. The machine features a 3.94-inch chuck size, accommodating medium-scale workpieces with practical versatility for job shop and production environments. Powered by 1.1 kW motor capacity, this unit delivers efficient energy consumption suitable for small-to-medium turning operations. The spindle achieves a maximum rotational speed of 8,000 RPM, providing adequate cutting velocities for various material types and finishing requirements. The FANUC 21iT controller offers robust CNC functionality with advanced features including cutter radius compensation, constant surface speed control, and support for multiple repetitive machining cycles. The control system incorporates a 7.2-inch LCD display with flat keyboard interface, supporting both English and Japanese languages for international operation. The 21iT platform provides programmable flexibility through G-code and M-code functions, enabling rapid traverse, linear interpolation, and helical interpolation capabilities. Data I/O connectivity includes RS232C serial communication for program transfer and parameter management. The minimum programmable unit resolution reaches 0.001 mm, ensuring precision dimensional control for tight tolerance work. This configuration suits tool-and-die operations, small parts production, and prototype development where compact footprint and controlled automation enhance productivity without requiring extensive floor space investment.
