Note :

Q: How does the High Precision Lathe Machine enhance metal turning and thread cutting operations?

A: The machines high spindle speed range (35-2000 RPM) and 12-step selection empower precise control over cutting conditions. Its sturdy cast iron body, large swing diameter (400 mm), and 4-way tool post enable stable and accurate metal turning and thread cutting, making it ideal for fine finishes or intricate thread profiles.

Q: What are the primary applications of this lathe machine in various industries?

A: This lathe is widely used for metal turning, thread cutting, part manufacturing, and producing surface finishes. It supports both medium and heavy-duty fabrication projects, making it valuable in automotive, industrial equipment, and custom fabrication sectors where precision and durability are critical.

Q: Where can this machine be installed and operated safely?

A: The machine can be set up in manufacturing workshops, industrial plants, educational institutions, or job shops equipped with adequate floor space (2150 x 850 mm) and a three-phase 415 V electrical supply. Proper flooring and ventilation are recommended to support its 1200 kg weight and ensure operator safety.

Q: When is it ideal to use this lathe for production or prototyping?

A: This lathe is best utilized during production runs requiring heavy-duty turning, thread cutting, or part manufacturing where precision is vital. Its versatility also makes it suitable for prototyping and custom fabrication tasks when quick adjustments and high accuracy are needed.

Q: What is the process for adjusting spindle speeds and slide travel?

A: Operators can select from 12 spindle speed steps using the control panel, adjusting for optimal material removal rates. Slide travel, both cross (230 mm) and longitudinal (600 mm), is controlled manually for accurate placement and sizing of cuts, providing flexibility for various workpiece dimensions.

Q: How does the manual control system benefit experienced machinists?

A: The manual control system allows experienced operators to finely tune operations, ensuring meticulous handling of each process. This fosters precision, especially during complex part manufacturing, and grants flexibility to adapt to different materials or design specifications with on-the-spot adjustments.

Q: What advantages does the lathe offer in terms of durability and longevity?

A: Constructed from cast iron and designed for heavy-duty performance, the lathe ensures minimal vibration and robust support during operations. Its durable build and painted surface protect against corrosion and mechanical wear, promoting long-term reliability and reducing maintenance needs.
