CLAUSING CK 80X240 CNC LATHES

Technical Description

This CNC lathe features an 80-inch swing and a 240-inch machining length, designed for high-precision turning of large workpieces. It is equipped with a Fanuc 18iT control system, providing advanced CNC functionality for complex machining operations. The control supports up to 7 axes, including C-axis contouring for live tooling and sub-spindle operations, enabling versatile multitasking capabilities. Rapid feed rates reach 787.4 inches per minute on linear axes and 550 RPM on the C-axis, while maximum turning feed rates are 393.7 inches per minute and 27.8 RPM respectively, ensuring efficient material removal and fine surface finishes. The main spindle operates from 500 to 10,000 RPM, with direct 5-digit S-code control and 0.01° indexing for precise rotational positioning. The spindle is driven by an AC spindle motor rated at 3 HP continuous and 5 HP for short-term duty. The tool post accommodates up to 6 tools, with 4 sleeves and 3–8 power-driven tools, supporting cross-milling and other live tooling operations at speeds up to 8,000 RPM. The sub-spindle provides speeds from 500 to 8,000 RPM, with 4-digit S-code control and 15° minimum indexing for secondary operations. The system includes a coolant unit with a 40.9-gallon capacity, supporting extended machining cycles. The Fanuc 18iT control offers comprehensive programming, diagnostics, and interface options, including inch/metric conversion, emergency stop, overtravel protection, and advanced interpolation features. This machine is suitable for heavy-duty turning, milling, drilling, and threading applications in industries requiring high accuracy and reliability.
