Tornos

What is Tornos?

Tornos is a Swiss machine tool manufacturer, best known for its long-turning automatic lathes, also known as Swiss-type lathes. The company was founded in Switzerland in the late 19th century, with its roots tied to the development of precision machining for the watchmaking industry in the Jura Mountains. Tornos manufactures CNC-controlled Swiss-type automatic lathes, multi-spindle automatic lathes, and turning centers, which are used in demanding manufacturing industries for high-volume and precision part production.

For machinists and machine shops, Tornos primarily means production solutions that combine high dimensional accuracy, efficient manufacturing of bar stock parts, and automated part handling.

Tornos and Swiss-type Automatic Lathes in Machine Shops

Tornos is one of the most well-known makers of Swiss-type automatic lathes. In a Swiss-type lathe, material is fed through the spindle using a bar feeder and supported by a guide bushing, which makes it possible to machine long and slender parts without deflection. This design improves dimensional accuracy and surface finish control, especially for parts with small diameters.

In machine shops, Tornos machines are typically used for series production of precision parts such as medical device components, connectors, shafts, and other high-precision items. Many models feature multiple tool positions, sub-spindles, and Y-axis turning, allowing for complex, multi-stage machining in one setup. This reduces setup times and increases repeatability.

Tornos Multi-Spindle Automatic Lathes and Production Efficiency

Tornos also manufactures multi-spindle automatic lathes, where several spindles simultaneously machine different parts at various stages of production. Multi-spindle technology increases productivity, particularly for the mass production of identical parts.

Multi-spindle automatic lathes are ideal for machine shops with high production volumes where unit cost is a key factor. CNC control combined with multiple spindles enables more flexible production compared to traditional mechanical automatic lathes.

Tornos and CNC Control in Machining

Modern Tornos machines are CNC-controlled machine tools that use advanced control systems and multiple interpolation axes. This enables the performance of complex shapes, threading, and milling operations on a single machine.

Integrated automation, tool magazines, and measurement solutions support lights-out manufacturing. For machine shops, this means better machine uptime, controlled machining values, and consistent quality even in large production runs.

Tornos as Part of the Global Manufacturing Industry

Tornos operates internationally and serves industries such as medical technology, automotive, electronics, and micromechanics. The company's reputation is based on extensive experience in precision turning and the development of Swiss-type technology.

The Swiss heritage is especially reflected in the structural precision and finish of the machines, but for machinists, what matters most is the machine’s ability to produce dimensionally accurate parts repeatedly and cost-effectively.

Summary

Tornos is a Swiss machine tool manufacturer specializing in CNC-controlled Swiss-type automatic lathes and multi-spindle automatic lathes. The company’s machines are used in machine shops, particularly for mass production of small, high-precision parts, combining Swiss-type technology, automation, and high repeatability.
