How much does the Index MS 40E 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 MS 40E is a six-spindle CNC multi-spindle automatic for bar up to 40 mm (1.57 in) in diameter, with spindle speeds to 7,000 rpm. INDEX gives the spindle drive as 24 kW with 57 Nm maximum torque, and the tooling as up to 16 cross tools plus 6 longitudinal tool posts. The control is listed as Index C200-4D (Siemens 840D hardware).
Six longitudinal posts on six spindle positions means every station can carry a tool working along the bar axis, for drilling, boring or threading, while the cross tools share out the radial turning, grooving and parting. On a machine of this kind the slowest station sets the cycle, so how the operations are spread over the positions decides output more than spindle speed does.
The power and torque figures match the MS 40-6, which INDEX lists at 13 / 24 kW and 31 / 57 Nm (100%/25% duty) with the same 7,000 rpm. Read the 24 kW and 57 Nm on this page as short-duty peaks and ask for the continuous rating before planning heavy roughing in steel. For small bar, the MS 16 runs to 10,000 rpm on 16 / 22 mm stock.

Strengths & Limitations
Strengths
- Takes bar up to 40 mm (1.57 in) on six spindles running to 7,000 rpm
- Up to 16 cross tools plus 6 longitudinal tool posts, enough for one end-working post at each spindle position
- Spindle drive listed at 24 kW with 57 Nm maximum torque
Limitations
- 24 kW and 57 Nm are given without a duty cycle; the MS 40-6 lists the same figures at 25% duty and 13 kW and 31 Nm at 100%
- Top speed of 7,000 rpm limits surface speed on small diameters; the MS 16 runs to 10,000 rpm
- The table gives no weight, footprint or rapid rates, so installation planning needs INDEX's layout data

Frequently Asked Questions
01
The headline figures line up. Both run to 7,000 rpm, and the MS 40-6 is listed at 13 / 24 kW and 31 / 57 Nm (100%/25% duty), where the MS 40E page gives 24 kW and 57 Nm. The MS 40-6 table adds a machine weight of 7,100 kg (15,653 lb) and names its control as Siemens S840D sl.
02
Bar up to 40 mm (1.57 in) in diameter. INDEX lists up to 16 cross tools and 6 longitudinal tool posts across the six spindle positions, so axial work such as drilling and boring can run at every station while the cross tools turn, groove and part off.
