SN 71 Classic service

SN 71 Classic service is provided for a robust universal center lathe originally manufactured by TOS / TRENS Trenčín. The SN 71 Classic was designed for single‑piece and small‑batch production and for machining large‑size workpieces. Thanks to its structural rigidity, wide spindle speed range and long service life, the SN 71 Classic remains a proven machine still widely operated in manufacturing workshops as well as maintenance and repair facilities.

Although production of the SN 71 Classic lathe has been discontinued, this model remains economically viable to operate thanks to its simple and highly durable mechanical design combined with continued service support and spare part availability.

Characteristics of the SN 71 Classic Lathe

The SN 71 Classic is a mechanical universal center lathe designed for machining large rotational components such as shafts, flanges and oversized technological parts. It enables a wide range of turning operations while maintaining high machining stability and good surface quality.

The lathe has found strong application not only in production environments, but also in:

maintenance operations,
repair workshops,
manufacturing of spare parts and custom-made components.

Construction, Stability and Machining Accuracy

The foundation of the SN 71 Classic lathe is its massive cast‑iron bed construction, ensuring high rigidity and excellent stability when machining larger workpieces. Thanks to this design:

the cutting process remains calm and stable,
the machine maintains long‑term accuracy,
wear of mechanical components is uniform and predictable.

The lathe features a wide spindle speed range, allowing optimal cutting conditions to be selected for various materials and workpiece diameters.

Everyday Operation and Operator Convenience

The SN 71 Classic is designed as a reliable workshop machine without complex electronics:

simple and ergonomic operation,
clear mechanical controls,
easy and fast maintenance.

This makes it particularly suitable for operations where emphasis is placed on:

operational reliability,
rapid response to customer orders,
low requirements for operator training and servicing.

Configuration Flexibility and Accessories

A significant advantage of the SN 71 Classic lathe is its versatility and adaptability to specific technological requirements. The machine was supplied in several versions and can be equipped with a wide range of accessories, allowing its use in diverse production and maintenance environments.

SN 71 Classic Service and Spare Parts

One of the main reasons why SN 71 Classic lathes are still widely used is their excellent long‑term serviceability. We provide complete SN 71 Classic service, including:

service and repair of mechanical components,
supply of SN 71 Classic spare parts,
spindle and gearbox repairs and adjustments,
restoration of geometric accuracy,
diagnostics of backlash and vibration,
