CLAUSING CK 70X122 CNC LATHES

Technical Description

The Star lathe with CNC Fanuc 18i-T control represents a heavy-duty turning center engineered for high-precision cylindrical machining operations. This machine accommodates workpieces up to 70 inches in swing diameter with a machining length capacity of 122 inches, making it suitable for large-scale component production across automotive, aerospace, and industrial sectors. The Fanuc 18i-T control system delivers advanced multi-axis capabilities with rapid feed rates reaching 787.4 inches per minute on linear axes (Z, X, Y, ZB, XB) and 550 RPM on the C-axis for rotational indexing. The main spindle operates continuously at 3 HP with peak performance of 5 HP (15 minutes/50% duty cycle), achieving maximum spindle speeds of 8000 RPM. The sub-spindle provides independent speed control from 500-8000 RPM with AC servo drive technology, enabling live-working back operations. This configuration features a seven-axis architecture with precision C-axis spindle indexing at 0.01-degree increments for complex geometric machining. The turret accommodates six tool stations with four sleeve positions and 3-8 power-driven tool options for cross-milling operations. Equipped with a 40.9-gallon coolant system featuring level and flow detectors, plus a 2.6-gallon hydraulic unit operating at 493 PSI, the machine ensures optimal chip evacuation and tool performance. Rapid air pressure capabilities of 72.5 PSI support pneumatic operations, while maximum part projection length reaches 1.18 inches with insert lengths up to 2.95 inches.
