Robust Construction for Heavy Duty Operations

This lathe's high rigidity and all-geared headstock provide the strength needed for heavy-duty machining tasks. The use of cast iron and steel enhances vibration resistance and durability, making it suitable for continuous use in demanding industrial environments such as roll turning and shaft machining.

Precision Engineering and Flexible Performance

With a 4000 mm capacity between centers and a maximum swing diameter of 800 mm, the BSN 4000 accommodates large components. Features like a 105 mm spindle bore, 18-step variable spindle speeds, and precision-ground bed ways allow for accurate cutting, threading, and finishing. The manual gear and lever control ensures operators maintain precise command over the machining process.

FAQ's of Broadbent BSN 4000 mm Heavy Duty Lathe Machine:

Q: How does the Broadbent BSN 4000 mm Lathe handle different materials and cutting thicknesses?

A: The lathe is engineered to work with various materials including cast iron and steel, thanks to its robust construction and powerful 7.5 kW main motor. It can accommodate cutting thicknesses up to 50 mm, depending on the material and tooling used, ensuring versatility for multiple heavy-duty machining tasks.

Q: What are the main benefits of the centralized lubrication system?

A: The centralized lubrication system delivers consistent lubrication to all critical components, reducing wear and maintenance requirements. This ensures smoother operation, prolongs the lifespan of the machine, and helps maintain precision during prolonged usage.

Q: Where is this lathe typically used and what kind of applications is it best suited for?

A: The Broadbent BSN 4000 mm Heavy Duty Lathe is ideal for applications such as roll turning, shaft machining, and use in heavy fabrication workshops. Its high rigidity and large work capacity make it especially suitable for industrial settings requiring precision and strength over extended periods.

Q: How is thread cutting managed on this lathe?

A: Thread cutting on the BSN 4000 is facilitated by a 50 mm lead screw and a wide thread cutting range: metric threads from 1 to 180 mm and inch threads from 2 to 40 TPI. Operators manually set gears and levers for the required thread pitch, ensuring flexibility and precision for various threading requirements.

Q: What process should be followed to change the spindle speed?

A: To change spindle speed, operators use the machine's manual lever and gear control system, selecting from 18 available speed steps ranging from 20 to 800 RPM. This allows adjustment for optimal cutting speed based on the material and operation, which supports precision and machine safety.

Q: When should the coolant system be used, and what advantage does it provide?

A: The electric coolant pump should be used during prolonged cutting operations or when machining difficult materials prone to heat build-up. Proper cooling helps prevent thermal distortion, preserves tool life, and ensures high-quality surface finishes.
