INDEX MS22C-8

The INDEX MS22C-8 is an 8-spindle CNC bar automatic in the 22 mm class, and on every figure listed here it matches the MS22-8: 8 work spindles, 16 tool carriers, 10,000 rpm and approx. 7,100 kg (15,653 lb). When two quotations name the two models, compare the configuration offered rather than the capability.

Bar capacity is 22 mm (0.87 in), with a bracketed 24 mm (0.94 in) that the table leaves unexplained. Spindle speed tops out at 10,000 rpm and falls with bar diameter, bar guide and workpiece clamping. The drive rating is 8.7 kW continuous and 15 kW at 25% duty (11.7 / 20.1 hp), torque 10 Nm and 18 Nm on the same basis, which points the machine at small parts rather than heavy stock removal.

Slide strokes are short: 62 mm (2.44 in) of X, 85 mm (3.35 in) of Z and 24 mm (0.94 in) of Y, the last tied to the Y-axis option. Hobbing and polygon turning are also on the option list, as are tool monitoring and the transmit function, so secondary operations such as flats or gear teeth can move onto the machine if those options are bought.

At the cut-off end, 1 or 2 synchronous spindles clamp 22 mm (24 mm), run to 10,000 rpm and deliver 9.2 kW at 100% / 12 kW at 40% duty with 11 / 14 Nm. A 138° swivel angle and 120 mm (4.72 in) of Z let them present the part to 3 / 6 rear tools, 2 / 4 of them live. An optional back-boring slide adds 1 or 2 tool carriers with 62 mm (2.44 in) of X.

For site planning: 3,349 x 2,032 x 2,854 mm (131.9 x 80.0 x 112.4 in) at maximum configuration without bar guide or loading magazine, and connected power of 53-77 kW, 63-91 kVA and 91-131 A at 400 V, 50/60 Hz depending on I/O devices. The control is the Siemens Sinumerik 840D Solution Line. The MS22C, a separate model, is lighter at approx. 5,700 kg (12,566 lb) and runs the INDEX C200-SL control.
