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 16 Plus is the large-bar version of INDEX's six-spindle MS16 automatic: the standard machine takes bar up to 16 mm (0.6 in) and the Plus takes 22 mm, with back-working spindles that clamp 22 mm to match. Each of the 6 spindles runs to 10,000 rpm, rated 8.7 / 15 kW and 10 / 18 Nm at 100% / 25% duty. INDEX gives a typical cycle time of 2 to 12 seconds per part, depending on the part, which places the machine in high-volume small-part production.

There are 6 stations, with up to 4 CNC slides per station and a rapid traverse of 30 m/min. INDEX describes the live tooling positions as expanded compared with the standard MS 16 but gives no count, so the driven-tool layout should be checked against the parts you plan to run before the order is placed.

Up to 2 back-working spindles finish the cut-off end. They run to 10,000 rpm, are rated 9.2 / 12 kW and 11 / 14 Nm at 100% / 40% duty, and clamp 16 mm or, on the Plus, 22 mm. Their continuous rating is slightly above that of the main spindles, so back-end drilling and turning do not have to be held back to protect the cycle.

The control is the Siemens S840D sl, and INDEX Connect provides Industry 4.0 and MES integration. The machine weighs 5,200 kg (11,464 lb) and its power supply is 49 kW depending on peripherals. Against the MS22-8, which has the same 8.7 / 15 kW spindle rating but weighs approx. 7,100 kg (15,653 lb), the MS 16 Plus is the lighter way to run 22 mm bar on a multi-spindle.

Strengths & Limitations

Strengths

Takes 22 mm bar against 16 mm (0.6 in) on the standard machine, with back-working spindles that clamp 22 mm too
Typical cycle times of 2 to 12 seconds per part
Up to 4 CNC slides per station across 6 stations, with 30 m/min rapid traverse
Up to 2 back-working spindles at 10,000 rpm, rated 9.2 / 12 kW at 100% / 40% duty
INDEX Connect for Industry 4.0 and MES integration

Limitations

Spindle torque is 10 / 18 Nm at 100% / 25% duty, light for heavy forming on 22 mm bar
INDEX gives no count for the live tooling positions, only that they are expanded over the standard MS 16
Continuous spindle power is 8.7 kW; the 15 kW figure applies at 25% duty only

Best For

High-volume parts from 16 or 22 mm bar Small parts with cycle times of 2 to 12 seconds Parts finished on both ends with back-working spindles Plants linking machines to MES through INDEX Connect

Frequently Asked Questions

01 What is the difference between the MS 16 Plus and the standard MS16?

Bar capacity. The standard machine takes 16 mm (0.6 in) bar and the Plus takes 22 mm, and the back-working spindles clamp 16 mm or 22 mm to match. INDEX also describes the live tooling positions of the Plus as expanded. The spindle figures in the table, 10,000 rpm and 8.7 / 15 kW, are not split by version.

02 How fast is the MS 16 Plus in production?

INDEX gives a typical cycle time of 2 to 12 seconds per part, depending on the part. Rapid traverse is 30 m/min, and with up to 4 CNC slides per station several operations can run at each of the 6 stations in the same cycle.

03 What back-working capacity does the MS 16 Plus have?

Up to 2 back-working spindles. Each runs to 10,000 rpm and is rated 9.2 kW at 100% and 12 kW at 40% duty, with 11 / 14 Nm of torque. They clamp 16 mm on the standard machine and 22 mm on the Plus.

04 What control and connectivity does the MS 16 Plus use?

The control is the Siemens S840D sl. INDEX Connect handles Industry 4.0 and MES integration, which matters if production data has to flow into a plant system. The power supply is 49 kW depending on peripherals, and the machine weighs 5,200 kg (11,464 lb).
