TOS CELAKOVICE SU 125H/4000 MANUAL LATHE

Technical Description

The TOS Čelakovice SU 125H/4000 is a heavy-duty manual lathe engineered for precision machining of large shaft-type and flange-shaped workpieces. It offers a maximum swing over bed of 1250 mm (49.21 inches) and a substantial distance between centers of 4000 mm (157.48 inches), enabling machining of very long parts. The spindle bore measures 122–130 mm (approximately 4.8 inches), allowing for substantial material passage and complex internal profiles. The lathe is powered by a robust 22–29.57 HP motor that drives the spindle at speeds up to 450 RPM, suitable for turning heavy and large-diameter workpieces with high stability and torque. It accommodates workpiece weights up to 6,000–8,000 kg depending on setup, with a machine weight around 9,500 to 11,900 kg ensuring rigidity during operation. The machine includes a standard tailstock with quill, a tool post for single-tool operations, and is designed for manual operation with mechanical feed and traverse controls. Its overall dimensions are approximately 7.9 meters long, 1.97 meters wide, and 1.48 meters high, reflecting its industrial-scale capacity. The SU 125H/4000’s design emphasizes versatility in turning large parts with capabilities for threading within a wide pitch range, and is suited for applications in heavy industries requiring precise turning of shafts, flanges, and other large rotary components.
