SUI 80 lathe service

SUI 80 lathe service is provided for this heavy‑duty universal lathe designed for the most demanding turning operations in piece and small‑lot production. The SUI 80 / SUI 80 Classic VS is characterized by an extremely rigid bed and tough mechanical construction, enabling stable machining even under very high cutting forces.

Thanks to its versatility, the SUI 80 lathe has been widely used not only in production workshops, but also in maintenance and repair divisions where reliability, strength and long service life are essential.

The machine was manufactured approximately from the 1970s to the 1990s, depending on version and configuration. Its sustained build quality and continuous development at the time positioned the SUI series among leading universal lathes worldwide.

Key Advantages of the SUI 80 Lathe

The SUI 80 / SUI 80 Classic VS offers a combination of high performance, precision and operational simplicity:

High output at very high cutting forces
Extremely rigid machine structure
High machining accuracy and repeatability
Simple, ergonomic and operator‑friendly control
Easy maintenance and servicing
Long service life
Low operating costs
Wide range of versions and optional accessories
Turning length of up to 8 metres
Hand scraping of critical machine parts for long‑term precision
Capability to cut a wide range of internal and external threads with multiple pitch options

These features make the SUI 80 a reliable solution for heavy‑duty turning applications even decades after its introduction.

Design and Mechanical Concept

The core of the SUI 80 lathe is its massive cast‑iron bed, designed to absorb vibration and ensure a calm and stable cutting process during long machining cycles. Hand‑scraped functional surfaces contribute to sustained geometric accuracy over the machine’s lifetime.

The mechanical concept emphasizes robustness, simplicity and long‑term maintainability, allowing efficient servicing and economically viable repairs even after many years of operation.

Standard Equipment (Typical Execution)

Typical standard configuration of the SUI 80 Classic VS includes:

Metric execution
