Tornos MultiDeco 20/8b

The Tornos MultiDeco 20/8b is a CNC 8-spindle multi-spindle automatic turning center with 20mm maximum bar capacity, representing Tornos's high-production platform for small-diameter precision components. The MultiDeco 20/8b is purpose-built as a CNC multi-spindle from the ground up—not a conversion of a mechanical predecessor—and incorporates Tornos's Swiss precision engineering tradition into a platform optimized for the highest-volume production of small turned parts in the 3–20mm diameter range.

The 8-spindle architecture of the MultiDeco 20/8b is the defining throughput advantage: eight workspindles simultaneously machine eight parts at eight different operation stages. With the drum indexing to advance parts through the operation sequence, effective cycle time equals only the longest single-position operation time. For a part requiring eight distinct machining operations, the MultiDeco 20/8b produces one completed part per index cycle—equivalent in throughput to eight individual CNC turning centers running identical parts simultaneously. This is the mathematical foundation of multi-spindle economics for high-volume production.

The MultiDeco 20/8b excels in the production of small precision components requiring multiple turning, drilling, threading, and cross-working operations. The 20mm bar capacity covers the broad range of precision screw machine work: hydraulic connectors, electronic pins and contacts, medical device components, watch components, automotive sensor housings, and precision hardware. Within this diameter range, the MultiDeco 20/8b's 8-spindle architecture maximizes per-machine throughput for the complete operation sequence.

Tornos integrates its TISIS software platform with the MultiDeco for programming, simulation, and production management. TISIS provides intuitive multi-spindle programming that accounts for the simultaneous multi-position operation architecture, collision detection simulation before cutting, and production monitoring integration. The software investment Tornos has made in multi-spindle programming tools reflects the real complexity of optimizing 8 simultaneous machining positions—a task that benefits significantly from purpose-built programming support.

The MultiDeco 20/8b is backed by Tornos's global service and applications network spanning Europe, North America, and Asia. For shops in all major manufacturing markets, Tornos provides local applications engineers experienced in multi-spindle production optimization—a meaningful support advantage for shops new to CNC multi-spindle production. Tornos's long history as the leading European multi-spindle and Swiss-type turning machine builder provides the applications knowledge base that supports successful multi-spindle production across diverse industries.
