How much does the Tornos MultiDECO 20/8 cost?
Estimated price range
Our best estimate for a multi-spindle automatic in this class — not a quote from Tornos. Configuration moves it a long way.
Overview
The Tornos MultiDECO 20/8 is an eight-spindle CNC bar automatic for stock up to 20 mm (0.787 in), with a listed machining length of 80 mm (3.15 in). It is not in Tornos's current lineup, so this page is for people assessing a second-hand machine. The listed figures should be checked against the documentation of the machine being offered.
All eight stations have CNC servo axes of their own, with up to 4 cross slides plus 1 longitudinal slide per station. Driven tools are listed at each spindle position and run at up to 6,000 RPM, so cross drilling and the milling of flats can be shared out around the stations instead of being crowded into one. A pick-off spindle takes the part for back operations, which lets the cut-off face be finished before the part leaves the machine.
Spindle power is listed as 3.7 kW (5 HP) per spindle. That is a modest figure, in keeping with a 20 mm bar, and it points the machine at small-diameter work in free-cutting materials more than at heavy form cuts in tough alloys. A guide bushing is listed for each spindle. It supports the bar close to the tool, which is what makes an 80 mm (3.15 in) part practical on stock this slender.
The listed weight is 7,200 kg. Before buying, establish which driven units, tool holders and bar loading equipment come with the machine, because the listed figures do not say.

Strengths & Limitations
Strengths
- Eight spindles with CNC servo axes at each of the 8 stations, so every position is programmed on its own
- Driven tools are listed at each spindle position, running at up to 6,000 RPM
- A pick-off spindle handles back operations, so the cut-off side is machined in the same cycle
- Up to 4 cross slides plus 1 longitudinal slide per station
- A guide bushing at each spindle supports parts up to the listed 80 mm (3.15 in) machining length
Limitations
- Bar capacity is 20 mm (0.787 in); larger stock is outside the machine
- Listed spindle power is 3.7 kW (5 HP) per spindle, which limits depth of cut in tough materials
- Driven tools are listed at up to 6,000 RPM, which is slow for very small drills and end mills
- At 7,200 kg the machine needs a floor and a rigging plan to match

Frequently Asked Questions
01
The listed figures give a maximum bar capacity of 20 mm (0.787 in) and a maximum machining length of 80 mm (3.15 in). A guide bushing is listed at each spindle, which supports the bar next to the cut and suits parts that are long in relation to their diameter.
02
Yes. A pick-off spindle for back operations is listed. It takes the part at cut-off so that the second end can be machined in the same cycle, and the part does not need a second operation on another machine for simple back-side features.
03
Driven tools are listed at each spindle position, with a driven tool speed of up to 6,000 RPM. That covers cross drilling and light milling. For very small cutters 6,000 RPM is a limit on surface speed, so check the tool diameters your parts call for.
04
Spindle power is listed as 3.7 kW (5 HP) per spindle across the eight spindles. On 20 mm (0.787 in) bar that is adequate for ordinary turning and drilling in free-cutting materials, while wide form tools in harder alloys will need conservative feeds.
