INDEX MS32C

The INDEX MS32C is a six-spindle CNC automatic for bar up to 32 mm (1.26 in). Its 6 work spindles run to 8,000 rpm, with the limit depending on bar diameter, bar guide and workpiece clamping, and each is rated 10.5 kW at 100% / 19 kW at 25% duty (14.1 / 25.5 hp) with 22 Nm / 40 Nm (16.2 / 29.5 ft-lbf). Against the MS16C, which reaches 10,000 rpm on 10 / 18 Nm, the MS32C gives up speed for more than twice the torque, which is what larger bar and bigger drills call for.

The front end is built from up to 12 cross slides with 72 mm (2.83 in) of X, 100 mm (3.94 in) of Z and 34 mm (1.34 in) of Y, plus up to 5 grooving slides with 72 mm of X and up to 5 boring slides with 100 mm of Z. With twelve cross slides across six positions, more than one slide can work at a single position. The Y-axis is listed as an option, so the Y stroke applies only where it is ordered.

Back-end work is done on up to 2 swiveling synchronous spindles: 8,000 rpm maximum and 6,000 rpm rated, 10 kW at 100% / 14 kW at 40% duty, 16 / 22 Nm, swivel angles of 126° / 132° and 130 mm (5.12 in) of Z travel. Up to 6 rear-end tools can be fitted, and a back-boring slide with 1 or 2 tool carriers brings 82 mm (3.23 in) of X and 3 tools, 2 of them live.

Control is the Siemens S840D Solution Line with teleservice, spindle stop and C-axis as standard; polygon turning, gear hobbing, tool monitoring, the Y-axis and the transmit function are options. Connected power is 34-74 kW and 40-87 kVA, at 400 V 50 Hz or 460-480 V 60 Hz, so the machine can be wired for either supply standard. In maximum equipment level, without bar guide or loading magazine, it measures 3,365 x 1,966 x 2,854 mm (132.5 x 77.4 x 112.4 in) and weighs approx. 6,800 kg (14,991 lb).
