TOS Czech SN-50B Gap Bed Lathe Machine

Q: How do I operate the TOS Czech SN55B Gap Bed Lathe?

A: The SN55B/SN-50B is a manual lathe with straightforward controls. After connecting to a 415V, 3-phase power supply, the operator uses handwheels and levers to adjust cutting speeds, feeds, and spindle direction. Consult the machine's manual for step-by-step procedures and safety guidance.

Q: What types of materials can the SN55B handle?

A: Thanks to its sturdy build and powerful 7.5 HP motor, the SN55B is suitable for turning steel, cast iron, aluminum, and other engineering metals. The cutting thickness depends on the tool and material being processed, making the lathe highly adaptable.

Q: When should the gap-bed feature be used?

A: The gap-bed design allows for machining larger diameter workpieces that would not fit over the standard bed. Use this feature when you need additional clearance for oversized flanges, discs, or components.

Q: Where can the SN55B lathe be installed?

A: With its industrial-grade design, the SN55B is suited for both small workshops and industrial settings. Ensure installation on a solid, level floor with sufficient space for its 3000 x 1000 x 1350 mm footprint, and access to 415V, 3-phase power.

Q: What is the process for cutting threads with this machine?

A: Set the lathe to the appropriate spindle speed and feed using the provided controls. The SN55B supports both metric (0.125 to 14 mm) and inch (2 to 112 TPI) thread ranges. Use the threading dial and carriage to guide the cutting tool, following best safety practices.

Q: What benefits does the SN55B Lathe provide over other models?

A: The SN55B's combination of high capacity (swing diameter, job length) and a broad selection of spindle speeds and feeds allows for versatile operations. Its inclusion of essential accessories (follow rest, job steady, coolant pump) and robust construction ensures lasting performance and operational flexibility.
