The BMT 3A80480 Giant Four-Guideway CNC Lathe is a heavy-duty, large-capacity turning machine purpose-built for machining extremely long, oversized, and high-weight components with maximum rigidity, torque, and precision. Featuring a massive 2,000 mm swing over bed, 12,000 mm distance between centers, and a wide 1,345 mm four-guideway bed construction, this industrial lathe delivers exceptional structural stability and vibration control for heavy cutting operations.
The high-torque 75 HP spindle motor (upgradeable to 100 HP), inverter-controlled spindle speeds from 5–400 rpm, and large Ø210 mm spindle bore with A2-15 nose allow the machine to handle large diameters and demanding materials with ease. With 48 cross and longitudinal feed selections, full metric and inch threading capability, a Ø60 mm rigid lead screw, 50 × 50 mm tool capacity, and a motorized heavy-duty tailstock with Ø290 mm rotary quill, the BMT 3A80480 ensures consistent accuracy, smooth finishes, and reliable performance across both roughing and precision turning.
Standard features such as automatic lubrication, coolant system, rapid traverse, and gearbox versatility enhance uptime and productivity, making this lathe an ideal solution for long shaft machining, large rollers and drums, mining and conveyor components, energy and power transmission parts, steel mill and marine fabrication work, as well as heavy repair and rebuild shops that require dependable machining of large-scale parts
