CLAUSING CK 80X437 CNC LATHE

Technical Description

This heavy-duty CNC lathe features an 80-inch swing and a machining length of 437 inches, designed for high-precision turning of large workpieces. The machine is equipped with a Fanuc 18iT CNC control system, providing advanced programming, diagnostics, and axis management for reliable and efficient operation. The control supports multi-axis functionality, including C-axis spindle indexing for live tooling and complex contouring. Rapid feed rates reach up to 787.4 inches per minute on linear axes, while the main spindle delivers a speed range of 500 to 10,000 RPM, driven by a 3HP continuous (5HP intermittent) AC spindle motor. The sub-spindle operates from 500 to 8000 RPM, enabling versatile backworking and secondary operations. The tool post accommodates up to 6 tools, with 4 sleeve positions and 3 to 8 power-driven tools, supporting cross-milling and other live tooling applications. The power-driven attachment reaches a maximum spindle speed of 8,000 RPM, controlled by an AC servo drive for precise synchronization. The system offers a minimum input increment of 0.0001 inch for high-resolution positioning and supports die cutting up to M8 x P1.25 and slotting up to 0.059 inch (width) x 0.157 inch (depth) with power-driven tools. The coolant unit has a 40.9-gallon capacity, ensuring effective chip removal and temperature control. The machine includes a part conveyor and optional live backworking tools, with collet options for secure workholding. The Fanuc 18iT control enables seamless integration with automation systems and provides comprehensive diagnostics, emergency stop, overtravel protection, and inch/metric conversion for flexible shop floor use.
