High-Precision Machining Capabilities

The Ernault Somua Lathe Machine provides superior accuracy for demanding metalworking tasks. Its robust cast iron construction and hardened bedways guarantee consistent results, while the advanced spindle design ensures stable machining at speeds up to 2000 RPM. This makes it an excellent choice for industries requiring fine tolerances and repeatable outcomes.

Versatile and Heavy-Duty Performance

Designed for heavy-duty operations, this lathe easily handles large workpieces, offering a generous 1500 mm distance between centers and 350 mm bed width. The combination of a 7.5 HP main motor and centralized lubrication ensures smooth, uninterrupted operation, even during intensive machining cycles.

User-Friendly Manual Operation

Despite its industrial strength, the Ernault Somua Lathe Machine is fully manual, making it accessible for operators who prefer hands-on control. The ergonomic arrangement of controls and durable 4-way tool post enable efficient setup and reliable operation across a variety of metal types and dimensions.

FAQs of Ernault Somua Lathe Machine:

Q: How is the Ernault Somua Lathe Machine best utilized in industrial settings?

A: This lathe is ideal for heavy-duty turning, threading, and facing of large metal workpieces, suited for both custom fabrication and series production in workshops and manufacturing plants. Its robust build and precision make it optimal for applications requiring consistent, high-quality results.

Q: What workpiece sizes can the lathe accommodate?

A: With a distance between centers of approximately 1500 mm and a maximum swing diameter of 520 mm, the machine can easily handle medium to large-sized components, including shafts, rollers, and flanges.

Q: When should I use the 3-jaw versus the 4-jaw chuck?

A: The 3-jaw chuck is ideal for holding round or hexagonal workpieces for quick centering and standard machining, while the 4-jaw chuck is preferred for irregular, square, or asymmetrical parts, allowing for precise manual adjustment of each jaw.

Q: Where is this lathe manufactured and who typically supplies it?

A: The Ernault Somua Lathe Machine is associated with French engineering and is typically available through exporters, importers, manufacturers, suppliers, and traders dealing in heavy industrial machinery.

Q: What processes and thread cutting ranges does the machine support?

A: The lathe supports both metric threading from 0.5 to 14 mm and inch threading from 2 to 56 TPI, enabling versatile threading operations for a wide range of applications.

Q: How does the centralized lubrication and coolant system benefit users?

A: Centralized lubrication ensures consistent and efficient distribution of oil to critical components, reducing wear and maintenance requirements. The fitted coolant system helps dissipate heat, promoting longer tool life and improved surface finish.

Q: What advantages does the hard bedway provide during operation?

A: Hardened bedways increase resistance to wear and deformation, maintaining long-term accuracy and machine stability even under heavy loading and extended operating periods.
