CW61160
Heavy duty lathe CW61160 is engineered for demanding turning operations on large-scale maritime, energy, and mining components.
Supporting up to 6,000 kg (6 tons) between centers, this large diameter lathe features a 1,640 mm max swing over bed and an ultra-wide 755 mm bed guide rail to absorb cutting forces and eliminate bed deflection during deep roughing passes.
Powered by a 22 kW main motor paired with an oil-bath lubrication system, the CW61160 provides 21 forward spindle speeds ranging from 3.15 to 315 RPM, delivering high gear-driven torque at low speeds for heavy alloy turning.
160 mm tailstock quill with an MT6 center taper supports heavy workpiece ends and prevents slender shaft whip during aggressive turning passes.
45x45 mm tool holder cross-section provides high resistance to flex and vibration during deep cutting and heavy facing operations.

Q: What industries and applications is the CW61160 heavy duty lathe designed for?
A: The CW61160 is designed for heavy machinery, marine engineering, energy, and mining manufacturing. It excels at turning large-diameter marine propeller shafts, turbine rotors, heavy hydraulic cylinders, mill rolls, and large flanges that require high torque and rigid structural support.
Q: How does the 755 mm bed width benefit heavy-duty machining?
A: A wider bed increases the distance between the front and rear guide rails, which lowers the machine's center of gravity and distributes the 6000kg load evenly. This prevents saddle twisting, dampens high-frequency cutting vibrations, and maintains axial straightness across long machining lengths.
Q: How does the CW61160 handle slender shafts to prevent deflection and whip?
A: To prevent shaft whip on long workpieces, the CW61160 heavy duty lathe utilizes a rigid 160 mm diameter tailstock sleeve with MT6 taper support. For workpieces where the length-to-diameter ratio (L/D) exceeds 4:1, optional steady rests (20-125mm/100-250mm) and follower rests should be used along the bedways to eliminate sagging and chatter.
