Overview

The Tornos MultiDeco 26/6b is a CNC 6-spindle multi-spindle turning center with 26mm maximum bar capacity, occupying the mid-range position in the MultiDeco series between the 20mm 8-spindle and the 32mm 6-spindle configurations. The 26/6b addresses the practical production requirement for a platform that handles medium-diameter barstock—parts too large for the 20mm class but not requiring the full 32mm capacity—while maintaining 6-spindle throughput advantages over single-spindle CNC turning.

The 26mm bar capacity of the MultiDeco 26/6b covers a significant segment of the precision turned component market: connector housings, valve bodies, hydraulic fittings, medium fasteners, sensor packages, and medical implant components in the 15–26mm diameter range. This diameter range represents the upper end of the traditional Swiss-type and screw machine market—parts too large for sliding-headstock Swiss-type machines but well-suited to fixed-headstock multi-spindle production with the throughput that justifies multi-spindle investment.

With 6 spindles operating simultaneously, the MultiDeco 26/6b produces one completed part per index cycle, with effective cycle time equal to the longest single-position operation. The 6-spindle configuration provides more operation positions than the traditional 5-spindle Davenport architecture—allowing more complex part geometries to be completed in a single setup—while the platform's multi-spindle throughput advantage over 6 individual single-spindle lathes makes the economics compelling for high-volume programs.

Tornos equips the MultiDeco 26/6b with live tooling capability at multiple spindle positions, enabling cross-drilling, milling, thread rolling, and polygon turning within the multi-spindle cycle. The end-working positions provide additional machining capability at the front and back face of the workpiece, and back-working features enable operations on the parted-off component's back face. The combination of these capabilities allows the 26/6b to complete complex components in a single setup that would otherwise require two or more separate machine operations.

The MultiDeco 26/6b is supported by Tornos's TISIS programming and simulation software, which manages the complexity of programming 6 simultaneous operation positions with collision detection, cycle time balancing tools, and production monitoring. For shops new to the MultiDeco platform, Tornos applications engineers provide training and first-article support to establish production on new part families efficiently.

Frequently Asked Questions

01 What is the bar capacity of the Tornos MultiDeco 26/6b?

The Tornos MultiDeco 26/6b accepts barstock up to 26mm (approximately 1.024 inches) in diameter. This covers medium-diameter precision turned components including hydraulic fittings, connector housings, valve bodies, and medium fasteners in the 15–26mm range.

02 Why does the 26/6b have 6 spindles instead of 8 like the 20/8b?

Larger bar diameter requires larger spindle bores, larger drum dimensions, and more structural mass per spindle—making it mechanically and economically impractical to fit 8 large spindles into the drum architecture at the same density as smaller spindles. The 6-spindle configuration is the practical optimum for the 26mm diameter class, and still delivers 6x the throughput per position compared to a single-spindle lathe.

03 Can the MultiDeco 26/6b replace a 32mm machine for most parts?

The MultiDeco 26/6b handles parts up to 26mm with full capability. If your actual parts are consistently 25mm or smaller in the critical machined diameter, the 26/6b is fully adequate. For parts requiring 27–32mm diameter or for the occasional larger-diameter part, the MultiDeco 32/6 with 32mm capacity provides the necessary clearance. Review your actual part diameter distribution before choosing between them.

04 Does the MultiDeco 26/6b support back-working?

Yes, the MultiDeco 26/6b supports back-working operations—machining the back face of parts after parting-off within the machine cycle. Back-working positions enable facing, drilling, chamfering, and threading on the back face without a secondary operation, enabling complete part machining in a single setup.

05 How does the MultiDeco 26/6b compare to the INDEX MS series at this diameter?

Both the Tornos MultiDeco 26/6b and INDEX MS series (specifically the MS32 at the nearest comparable diameter) offer high-quality CNC multi-spindle production. The INDEX MS32 series typically offers 8 spindles versus the MultiDeco's 6, providing higher throughput for parts within the diameter range. The MultiDeco 26/6b may be preferred for the 26mm diameter sweet spot, shops already in the Tornos ecosystem, or applications where TISIS programming advantages are valued.
