The Long-Bed Conventional Lathe is a heavy-duty manual turning center engineered specifically for precision machining of extra-long shafts, large rollers, hydraulic cylinders, and long tubular components. Built on a high-tensile cast-iron bed with extended induction-hardened guideways, this turning machine provides exceptional rigidity and vibration damping during continuous heavy-duty cutting operations. It combines classic manual control with high-torque mechanical drives, making it an ideal cost-effective solution for custom machine shops, heavy equipment repair facilities, and low-volume industrial manufacturing.

Long-Workpiece Capacity
Provides continuous tool carriage travel up to 11.8 meters, ensuring smooth surface finishes without needing to reposition long components mid-process.
Machine bed sizes are matched directly to your maximum turning length rather than total bed footprint, leaving sufficient stroke allowance for heavy chuck jaws, carriage travel, and tailstock positioning.
Heavy Cast-Iron Structure: The heavily ribbed bed absorbs chatter during aggressive rough turning, preserving turning accuracy and prolonging cutting tool life.
Headstock through-bore options up to 130 mm accommodate long raw pipes, drill tubes, and bar stock directly through the spindle for front-end facing and threading.
Allows rapid switching between metric, imperial, module, and diametral pitch threads without frequent manual gear changes.
Precision turning of bearing seats, keyways, and step-downs on long marine propeller shafts, turbine rotors, and power transmission axles.
Facing and external diameter turning for conveyor drums, steel mill rollers, and large-diameter processing cylinders.
Threading and internal boring on long hydraulic cylinder tubes, oilfield casings, drill rods, and structural pipes.
Versatile manual setups make it ideal for quick-turn maintenance tasks, custom shaft re-tipping, and single-piece replacement part fabrication.
Heavy-duty closed steady rests and carriage-mounted follow rests prevent slender shafts from sagging or flexing under tool pressure.
Supports large 4-jaw independent chucks, faceplates, and heavy-duty live centers to ensure stable clamping across diverse workpiece profiles.
Maximum workpiece outer diameter, total physical length, and required machining turning length.
Raw material grade, solid or tubular structure, and approximate workpiece weight.
Required spindle bore clearance, threading pitch types, and preferred electrical voltage.
Necessary accessories such as steady rests, follow rests, chuck sizes, or digital readouts (DRO).
