SEIBU SNC-28PI CNC LATHE

Technical Description

This precision CNC turning center features a FANUC 21i-T control system, a industry-standard platform designed for automated machining operations on lathe and turning applications. The system incorporates advanced axis control capabilities, including support for rotary axis management and synchronized multi-axis operations for complex part geometries. The machine is equipped with a 3.94-inch chuck for secure workpiece clamping, providing adequate holding capacity for medium-scale production runs. The spindle delivers 2.2 kW of cutting power, enabling efficient material removal across various workpiece diameters and material types. Operating at a maximum spindle speed of 10,000 RPM, this machine accommodates both high-speed finishing operations and lower-speed heavy roughing applications, with constant surface speed control capabilities to optimize tool life and surface finish. The FANUC 21i-T control offers comprehensive I/O device configuration with standard RS-232 communication protocols supporting 9600 baud rate transmission for program transfer and system diagnostics. The control supports conversational programming alongside G-code, enabling operators to develop and modify programs directly at the machine interface. Parameter configuration allows customization of axis limits, feed rates, and tool offsets to match specific production requirements. The system includes tool turret control for automatic tool selection and positioning, facilitating unattended production cycles. Safety interlocks and speed-limiting functions prevent excessive spindle acceleration during constant surface speed operations, protecting both tooling and workpiece integrity during automated machining sequences.
