Tornos - Swiss type machine MULTIDECO 20/8b

Eight spindles mean more positions and hence more operations, with the facility of completing all types of parts in good finished quality! This means that Tornos can now offer a highly versatile lathe for the production of hitherto impossible parts.

The Tornos product range is growing all the time so as to meet customer requirements in a more targeted manner. The company is now proud to present its 8-spindle lathe that also benefits from the DECO 2000 concept!

The DECO 2000 concept applied to an 8-spindle lathe: the ease of programming coupled with the absolute power of a multispindle machine with 8 stations enables you to consider all forms of production ranging from the highly complex to the most demanding in terms of quality and precision.

Eight spindles mean more positions and hence more operations, with the facility of completing all types of parts in good finished quality! This means that Tornos can now offer a highly versatile lathe for the production of hitherto impossible parts.

The mechanical part of the lathe, based on items that have been tried and tested on the MULTIDECO 20/6b & 26/6 (Hirth toothed gearing, triple roller bearings and a base made from mineral cast iron) coupled with the vast experience gained with conventional multispindle lathes (SAS and BS), is ideally completed by the hybrid concept used for the MULTIDECO 20/6b & 26/6, namely a cam-shaft to ensure the minimum of down-times, coupled with the vast power of the PNC-DECO.

Compared with a MULTIDECO 20/6b, the MULTIDECO 20/8b has two additional stations for producing highly complex parts (e.g. cross operations on the additional stations) at much improved finish qualities (rough and finishing work on 2 stations).
