SN 500 Classic lathe service

SN 500 Classic lathe service is provided for this robust universal center lathe originally manufactured by TOS / TRENS Trenčín, which is widely recognized as a proven machine for single-piece and small-batch production. Thanks to its solid mechanical design, high precision and operational reliability, the SN 500 Classic has secured a long‑term position not only in standard production workshops, but also in maintenance and repair facilities.

Although production of the SN 500 Classic lathe has been discontinued, its simple and extremely robust construction allows it to remain in regular operation. With professional servicing and proper maintenance, the machine continues to deliver high practical value and a long service life.

Characteristics of the SN 500 Classic Lathe

The SN 500 Classic is a mechanical universal center lathe designed for machining medium‑sized workpieces. It enables:

Machining of external and internal cylindrical surfaces
Machining of conical and spherical surfaces
Cutting of all common types of internal and external threads

The lathe was also produced in a special configuration with an increased spindle bore of up to 105 mm, significantly expanding its technological capabilities, particularly for shaft machining applications.

Design, Stability and Performance

The foundation of the SN 500 Classic lathe is a massive cast‑iron bed that ensures high rigidity and stable cutting performance, even during demanding machining operations. Thanks to this construction, the machine maintains long‑term geometric accuracy and repeatability.

The lathe is powered by a 7.5 kW main motor, which, combined with stable spindle bearing arrangements, enables efficient machining of a wide range of materials.
The spindle B8 (77 mm), or B11 (105 mm) in special versions, allows the machining of large workpieces and semi‑finished products.

Simple Operation and Productive Use

The SN 500 Classic was designed with an emphasis on:

Simple and ergonomic operation
Easy workshop maintenance
Low operating costs

The lathe is equipped with rapid traverse in both axes, significantly increasing operator productivity in single‑piece and small‑batch production. A straightforward threading system enables cutting all common thread types without complex machine reconfiguration.

Configuration Flexibility and Accessories

One of the greatest advantages of the SN 500 Classic lathe is its versatility. The machine was supplied in multiple configurations and can be equipped with a wide range of accessories, including:

Various types of steadies and supports
Special clamping and fixturing equipment
Customized technological solutions
Machine configurations tailored to specific production requirements

Thanks to this flexibility, the SN 500 Classic remains suitable for a broad spectrum of operations — from standard manufacturing and repair shops to maintenance of industrial machinery.
