INDEX C100

The INDEX C100 is a three-turret production turning center for bar up to 42 mm (1.7 in), with a main spindle and a counter spindle of the same 42 mm capacity. Both spindles run to 7,000 rpm on an A2-5 nose, and the maximum turning length is 400 mm.

The three turrets set the C100 apart. Each has 70 mm (2.76 in) of Y stroke, so up to three tools can work at once, split between the main and counter spindle, and the cycle shortens to the longest of the parallel operations. The turret entry reads 3 (10x VDI25 each), while the station table gives VDI20: 14; VDI25: 10, so a VDI20 turret carries more tools. Live tools run at 8,000 rpm with 6.2 kW and 11 Nm.

The main spindle is rated 25 / 29 kW (100%/25% duty) and 49 / 65 Nm (100%/40% duty), the counter spindle 16.5 / 19 kW and 32 / 43 Nm. Travels are 70 mm (2.8 in) in X, 70 mm (2.8 in) in Y and 250 mm (9.8 in) in Z, with rapids of 30, 15 and 60 m/min and acceleration up to 1G. The C-axis positions to 0.001°, and the chuck size is 110 mm (4.3 in).

Against the C200, the C100 gives up turning diameter and length (the C200 lists 220 mm and 550 mm with a 160 mm chuck) for higher spindle speed, 7,000 rpm against 6,000 rpm / 3,500 rpm. The C100 weighs 5,700 kg (12,566 lb), needs a 57 kW supply and occupies 5,990 × 1,706 × 2,138 mm (L × W × H). The control is Siemens S840D sl / FANUC Version 31i-B.
