How much does the INDEX MS40C-8 cost?
Estimated price range
Our best estimate for a multi-spindle automatic in this class — not a quote from INDEX-Werke. Configuration moves it a long way.
Overview
The INDEX MS40C-8 is an eight-spindle multi-spindle automatic for bar up to 40 mm (1.57 in), with a listed 5,000 RPM and 14 kW (18.8 hp) per spindle. The listed figures put the turning length at 120 mm (4.72 in) and the spindle bore at 45 mm. Confirm each figure with INDEX before committing a job to it.
Eight positions is the point of the machine. With up to 3 cross slides per spindle, up to 2 end working units per station and up to 64 tool positions in total, a part can be broken into eight short steps, and the slowest step sets the cycle. The back working spindle has a C-axis, so cross holes, flats and features on the cut-off end can be finished before the part leaves the machine. Up to 51 CNC axes are listed, which is a programming and setup load as much as a capability.
Against the MS 40E, which takes the same 40 mm bar on six spindles at up to 7,000 rpm, the MS40C-8 gives up spindle speed for two more stations. On small diameters in free-cutting material the speed gap matters; on parts with many operations the extra stations usually matter more.
This is a big machine to place: the table lists 14,000 kg (30,865 lb) and a footprint of approx. 5.2 x 2.8 m (17.1 x 9.2 ft). The control is listed as Siemens 840D sl.

Strengths & Limitations
Strengths
- Eight spindles with up to 3 cross slides each and up to 2 end working units per station
- Up to 64 tool positions, so parts with many features can be finished in one cycle
- Back working spindle with C-axis for machining the cut-off end before the part drops
- 40 mm (1.57 in) bar capacity through a 45 mm spindle bore, with 14 kW (18.8 hp) per spindle
Limitations
- 5,000 RPM per spindle limits surface speed on small diameters; the six-spindle MS 40E runs to 7,000 rpm on 40 mm bar
- Turning length is 120 mm (4.72 in), so long shafts are out of range
- At 14,000 kg (30,865 lb) and approx. 5.2 x 2.8 m (17.1 x 9.2 ft), it needs a prepared floor and generous space
- Up to 51 CNC axes makes setups and programs complex; allow engineering time for every new part

Frequently Asked Questions
01
Both take 40 mm bar. The MS40C-8 has 8 spindles at a listed 5,000 RPM and 14 kW (18.8 hp) per spindle. The MS 40E has 6 spindles, runs to 7,000 rpm and is listed with 24 kW. The two extra stations favour parts with many operations; the higher speed of the MS 40E favours small diameters.
02
The listed turning length is 120 mm (4.72 in). Bar capacity is 40 mm (1.57 in) through a 45 mm spindle bore. Anything longer than the turning length needs a second operation or a different machine, so check the longest turned feature on the drawing first.
03
The table lists a back working spindle with C-axis. With the C-axis the cut-off end can be faced, drilled and given off-centre holes or flats before the part is ejected, instead of in a second setup. End working units, up to 2 per station, handle drilling and boring along the axis on the front side.
04
The listed weight is 14,000 kg (30,865 lb) and the footprint approx. 5.2 x 2.8 m (17.1 x 9.2 ft). Ask INDEX whether that footprint includes the bar loading equipment, and plan the foundation for the weight. The control is listed as Siemens 840D sl.
