How much does the Tornos MultiDeco 20/8b 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 20/8b is listed as an eight-spindle CNC bar automatic for stock up to 20 mm (0.787 in), with spindle speeds up to 10,000 RPM per spindle. It is not in Tornos's current lineup. The listed figures are few and approximate, so they are a starting point for inspecting a second-hand machine, not a full specification.
What they do establish is the class of work. Eight spindles on a 20 mm bar are for small turned parts in long runs, and 10,000 RPM keeps surface speed up on the small diameters where slower spindles fall short. Live tooling is listed as available at multiple spindle positions, with multiple NC axes per position. Neither is counted, so find out how many driven tools and axes the machine in front of you carries. Programming is listed under Tornos TISIS. Plan for a weight of approximately 8,000 to 10,000 kg and a floor space of approximately 3.5 m × 2.5 m.

Strengths & Limitations
Strengths
- Up to 10,000 RPM per spindle, which keeps surface speed up on bar well under the 20 mm (0.787 in) limit
- Eight spindles, with live tooling listed as available at multiple spindle positions
- Multiple NC axes at each spindle position
Limitations
- The listed figures give no part length, spindle power or tool count, so capacity has to be confirmed on the machine
- Bar capacity ends at 20 mm (0.787 in)
- Weight is given only as a range, approximately 8,000 to 10,000 kg, which is too loose for a rigging or foundation plan

Frequently Asked Questions
01
The listed figures give a maximum bar capacity of 20 mm (0.787 in) across eight spindles, with spindle speeds up to 10,000 RPM per spindle. Part length is not listed, so measure the working stroke on the machine before planning a part around it.
02
Floor space is listed as approximately 3.5 m × 2.5 m and weight as approximately 8,000 to 10,000 kg. Both are approximations. Add space for bar loading and chip handling, and take the exact weight from the machine's plate before arranging transport.
03
Live tooling is listed as available at multiple spindle positions, and each position has multiple NC axes. The number of driven tools is not stated, so what a particular machine can mill or cross-drill depends on the units fitted to it.
