The bar turning reference since 1880
The original since 1880. Tornos' origins date back as far as the 1880s, which saw the production of the first machines designed for machining watch parts in Switzerland. During the 1960s and 1970s, three local companies ¬ Tornos, Bechler and Petermann - merged to form a single enterprise which, over the years, gained an impressive reputation across global markets. Tornos was behind the first sliding headstock turning machines. Produced to service the watchmaking industry, the sliding headstock machine quickly proved itself as a high-performance machining solution allowing parts exceeding the ratio of 3 to 4 times the bar diameter to be produced. The sliding headstock turning machine, or Swiss Type Lathe, has one fundamental characteristic: the tool is fixed, and the bar itself moves longitudinally. The bar is supported by a component known as the guide bush; this vital part prevents problems caused by the bars bending. Sliding headstock turning machines therefore allow rotating parts to be produced with the greatest precision.
Tornos now offers the following range of automatic turning machines in the turning field:
Single-spindle numerical control with sliding headstock
Tornos has been a recognised specialist in sliding headstock turning machines for over 100 years. We benefit from unrivalled expertise, which means we can offer our customers complete turnkey solutions. Our product range can respond to all of our customers' needs, whatever the diameter or the field of application. We have worked ceaselessly to develop innovative machining solutions, and we will continue to innovate in order to increase our technological advantage.
Multispindle parallel numerical control
Multispindle turning machines quadruple the rates of single-spindle machines. With 6 or 8 spindles, Tornos' multispindle machines allow bar operations to be serialised. The MultiAlpha and MultiSigma ranges can be equipped with double counter spindles. Capable of being fully adapted to our customers' needs, these machines are an ideal, efficient solution for large production runs. Multispindle turning machines are known as fixed headstock machines, and do not have guide bushes. In 2011, Tornos launched a new product range known as MultiSwiss. This range provided the link between single-spindle sliding headstock turning machines and multispindle machines. The truly revolutionary MultiSwiss is the first multispindle sliding headstock turning machine on the market.
Multispindle cam-controlled with programmable automated controller
The SAS 16.6 has become synonymous worldwide with precision, reliability, durability and, above all, exceptional productivity. Known and appreciated by our customers as quite simply the best multispindle small diameter cam-controlled machine in the world, the SAS 16.6 is a mechanical masterpiece. This machine now represents a high-performance machining solution for simple parts with high output rates.
