Tornos MultiDECO 36 CNC Multi-Spindle Automatic

The Tornos MultiDECO 36 is a CNC multi-spindle automatic turning center with 36mm maximum bar capacity, representing the large-diameter end of the MultiDECO series and one of the most capable production platforms for precision turned components in the 32–36mm diameter class. The MultiDECO 36 serves industries where part geometry complexity, dimensional precision, and sustained production volume converge at the upper edge of standard multi-spindle bar capacity: hydraulic system components, automotive powertrain parts, aerospace fastener production, fluid power fittings, and industrial connector manufacturing.

The 36mm bar capacity defines the production envelope. Components that must use the full bar diameter — flanged fittings, hex-drive fasteners with large across-flats dimensions, valve bodies requiring large through-bores, and precision connectors where the turned OD forms a structural feature — require a 36mm-class machine. The MultiDECO 36 provides this capacity within the multi-spindle architecture that delivers throughput equivalent to operating six or more individual turning centers simultaneously. For components in the 32–36mm range with annual volumes measured in hundreds of thousands or millions of parts, the MultiDECO 36 offers production economics that no single-spindle configuration can replicate.

Tornos equips the MultiDECO 36 with comprehensive machining capability across its spindle positions: end-working stations, cross-slide tools with live tooling options, and back-working capability that enables operations on the parted-off component's back face within the same machine cycle. Turning, drilling, threading, cross-milling, slotting, and back-face operations combine in the multi-spindle cycle to deliver complete finished parts in a single setup. For hydraulic fittings and precision fluid power components — where thread quality, bore concentricity, and surface finish must all be held simultaneously — this single-setup discipline directly reduces part handling costs and eliminates the re-clamping variation that affects multi-operation single-spindle production.

The MultiDECO 36 is programmed using Tornos TISIS software, the purpose-built multi-spindle programming and simulation environment that manages the complexity of coordinating multiple simultaneous machining positions. TISIS provides full 3D collision simulation before metal cutting, cycle time analysis with operation balance optimization across spindle positions, and real-time production monitoring for OEE visibility. Tornos applications engineers with dedicated multi-spindle expertise support installation, first-article qualification, and ongoing production program development. For shops transitioning from cam multi-spindles or single-spindle cells to CNC multi-spindle production, Tornos provides structured technical onboarding through its global applications center network.
