Index MS 16

The INDEX MS 16 is a six-spindle CNC multi-spindle automatic for bar up to 16 mm (0.63 in), with 16 / 22 mm given for the range as a whole. Spindle power is listed at 15 kW and maximum spindle torque at 18 Nm. Those are the 25% duty figures INDEX gives for the MS 16 Plus, whose continuous ratings are 8.7 kW and 10 Nm, so sustained cuts should be planned on the lower values.

On the tooling side, up to 3 positions carry live tooling, with live tools running to 10,000 RPM, and each spindle position has up to 2 NC axes plus live tool axes. That points the machine at small turned parts with a few drilled or milled features rather than parts where every station needs a driven tool. The table is inconsistent on the total tool count, the top spindle speed, the control version and the machine weight, so get those four from INDEX for the configuration quoted rather than taking any single row at face value.

The MS 16 Plus, which INDEX presents alongside the MS 16, lists 10,000 rpm, 30 m/min rapid traverse, a Siemens S840D sl control and 5,200 kg (11,464 lb). The Plus is the 22 mm version; the standard machine is the 16 mm (0.63 in) one. For smaller bar still, the TRAUB MS12-4 takes 13 mm (0.5 in) at 15,000 rpm on 4 spindles stacked in four levels.
