The CW6180 Large-Bore Conventional Lathe is a heavy-duty horizontal manual lathe engineered for heavy material removal and precise finishing on large-diameter shafts and long industrial piping. Constructed on a 600 mm wide induction-hardened bedway, it offers an 800 mm swing over bed and a 100 mm standard spindle bore. For specialized oilfield drilling, hydraulic cylinder, and heavy tube processing, an optional 140 mm through-bore configuration ensures continuous material passage without sacrificing turning rigidity.
Key Structural Features
Rigid Spindle System: Supported by a 3-bearing structure and powered by an 11 kW main motor, delivering massive cutting torque across 18 speed steps (6–750 rpm).
Hardened Bedways: Heavy cast-iron monoblock bed with high-frequency hardened guideways and soft saddle lining ensures low friction, smooth carriage travel, and minimal wear over years of operation.
Universal Threading Gearbox: Built-in feed box cuts metric, inch, module, and diametral threads directly without requiring frequent gear swaps or external accessories.
Machining Performance & Accuracy
Roundness Error: Maintained within 0.01 mm over a 300 mm measuring length under standard cutting conditions.
Cylindricity Error: Controlled within 0.04 mm over a 300 mm test piece to guarantee straight turning performance.
Rapid Traverse Rate: 4,000 mm/min rapid travel speed for longitudinal and cross feeds drastically cuts down non-productive setup cycles.
Applications of CW6180 Large-Bore Conventional Lathe
Heavy Shaft Turning: Precisely machines outer diameters, steps, tapers, and end faces on solid forged shafts up to 6,000 mm in total length.
Pipe & Sleeve Processing: The 100 mm or 140 mm spindle clearance allows seamless end-threading, internal boring, grooving, and facing on long tubular workpieces.
General Industrial Maintenance: Delivers reliable roughing and fine finishing across structural steel, cast iron, stainless alloys, and non-ferrous metals.
