How much does the INDEX MS20-6 cost?
Estimated price range
Our best estimate for a multi-spindle automatic in this class — not a quote from INDEX-Traub. Configuration moves it a long way.
Overview
The INDEX MS20-6 is listed as a six-spindle CNC automatic for bar up to 20 mm (0.787 in), with a maximum turning diameter of 28 mm (1.10 in) and up to 80 mm (3.15 in) of machining length per spindle position. Spindles run up to 10,000 RPM and live tools to 8,000 RPM. INDEX does not show this model on its current product pages, so confirm the listed figures before relying on them.
Each spindle position has up to 2 NC axes plus live tool axes and up to 4 tools, 24 in all. Rapid traverse is 30 m/min and the control a Siemens 840D sl. Power consumption is listed at 55 kVA. A turning diameter larger than the bar capacity only applies to work not turned from full bar, so ask how the 28 mm (1.10 in) figure is meant before quoting a part on it.
Against the MS 16, which lists 16 / 22 mm bar, a 25 mm (0.984 in) maximum turning diameter and live tools to 10,000 RPM, the MS20-6 is the slightly larger machine with slower live tools. Its listed weight of approx. 12,000 kg (26,455 lb) is heavy next to the approx. 7,100 kg (15,653 lb) of the MS22-8, so check it before planning transport and the foundation.

Frequently Asked Questions
01
INDEX does not show it on its current product pages. The listed figures, 20 mm (0.787 in) bar on 6 spindles at up to 10,000 RPM, should be confirmed with INDEX or from the machine's documentation before purchase.
02
The listed figures give bar up to 20 mm (0.787 in), a maximum turning diameter of 28 mm (1.10 in) and up to 80 mm (3.15 in) of machining length per spindle position. Ask how the turning diameter applies, since it is larger than the bar.
03
Up to 4 tools per spindle position, 24 in all, with up to 2 NC axes per position plus live tool axes. Live tools run to 8,000 RPM, and the rapid traverse is 30 m/min.
04
The MS 16 lists 16 / 22 mm bar, a 25 mm (0.984 in) maximum turning diameter, 15 kW and live tools to 10,000 RPM. The MS20-6 takes 20 mm (0.787 in) bar and turns up to 28 mm (1.10 in), with live tools to 8,000 RPM, and lists no spindle power.
