High Precision Machining for Versatile Applications

This lathe delivers reliable surface finishes, adjustable cutting thickness up to 15 mm, and accommodates various materials thanks to its sturdy cast iron body and hardened bed. The centralized lubrication and integrated coolant systems optimize operation, safeguarding both machinery and workpiece. Ideal for workshops and industry settings.

User-Friendly Manual Controls and Semi-Automatic Operation

With its manual lever and knob controls, operators have fine control over parameters, including spindle speed, feed rate, and threading. The quick-change tool post expedites setup, while the spacious work area and ergonomic design improve workflow for detailed and repetitive jobs.

Efficient Thread Cutting and Feeding Capabilities

The machine supports a broad thread cutting rangemetric (0.514 mm) and inch (256 TPI)with longitudinal feed from 0.04 to 2.00 mm/rev, enabling precise and diverse threading and turning operations. Tailstock quill travel (180 mm) and generous cross slide movement facilitate adaptability to different job requirements.

FAQs of Ernault Somua Precision Lathe Machine:

Q: How does the Ernault Somua Precision Lathe Machine ensure a high-quality surface finish?

A: The machine features a hardened and ground bed, supported by a centralized lubrication system and integrated coolant pump, maintaining optimal temperature and lubrication. These qualities help achieve a surface finish of RA < 2.5 m.

Q: What is the process for threading on this lathe?

A: Threading is facilitated through manual lever and knob controls, with the machine supporting metric threads from 0.514 mm and inch threads from 256 TPI. Users select from 16 spindle speed steps and adjust feeds accordingly for precise results.

Q: Where can this lathe machine be used, and what materials can it process?

A: It is suitable for heavy-duty workshops, manufacturing units, and industrial settings. The cast iron body and adjustable cutting parameters allow processing a wide variety of ferrous and non-ferrous metals.

Q: When is it beneficial to use this model over a CNC lathe?

A: This conventional, semi-automatic lathe is ideal when manual precision, rapid setup changes, and tactile control are preferredespecially for custom, one-off jobs or environments where CNC automation is not needed.

Q: What are the main features that support heavy-duty operation?

A: Key features include a 1500 mm distance between centers, 5 HP motor, robust cast iron body, hardened and ground bed, and quick change tool postall designed for reliable, heavy-duty use.

Q: How does the integrated coolant system improve machine performance?

A: The integrated coolant pump actively reduces heat during machining, preserves tool life, and enhances surface quality, supporting consistent performance in prolonged operations.

Q: What benefits do users gain from the centralized lubrication system?

A: Centralized lubrication ensures even oil distribution to critical moving parts, reducing wear, minimizing maintenance, and prolonging the machines operational lifespan.
