Price estimate
We do not have a price for the TRAUB MS12-4 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The TRAUB MS12-4 is a four-spindle automatic for bar up to 13 mm (0.5 in) that works either as a fixed-headstock or as a sliding-headstock machine: Z travel is 52 mm (2.0 in) fixed and 130 mm (5.1 in) sliding, and maximum turning length is 130 mm (5.1 in). Its 4 main spindles are stacked vertically in four levels, each running to 15,000 rpm with 3.5 kW at 100% and 4.4 kW at 40% duty (4.7 / 5.9 hp) and 6.7 / 8.6 Nm (4.9 / 6.3 lb-ft).
There are 4 turrets, one for each spindle level, with 8 live TRAUB KPS36 stations (W serration) each. Live tools run to 12,000 rpm at 1.0 / 2.6 kW (1.3 / 3.5 hp) and 2.7 / 7.6 Nm (2.0 / 5.6 lb-ft) at 100% / 25% duty. Turret travel is X 43 mm (1.7 in) and Z 52 mm (2.0 in), with Y ±8°. Flex tool carriers can be fitted in numbers of 0, 2 or 4, with X 85 mm and Z 90 mm, and the C-axis resolves 0.001°.
Counter spindles come as 2 or 4, each running to 15,000 rpm, rated 5.1 / 5.4 kW (6.8 / 7.2 hp) at 100% / 40% duty but only 3.1 Nm (2.3 lb-ft) at 100% duty. They travel X 128 mm (5.0 in) and Z 152 mm (6.0 in). The low torque figure points the back end at small-tool finishing, not heavy cuts. Coolant runs at 120 bar, and an optional flushing unit handles parts up to 55 mm long and 13 mm in diameter.
Control is the TRAUB TX8i-s V8 with dual NCU, operated from a 19-inch touchscreen with iXpanel. Fully equipped, excluding coolant system and chip conveyor, the machine weighs 8,000 kg (17,637 lb) and measures 5,778 x 1,716 x 2,404 mm (227.5 x 67.6 x 94.6 in). Power requirement is 65 kW / 76 kVA, 125 A. Against the MS16C, which runs to 10,000 rpm with 8.7 kW at 100% duty, the MS12-4 trades spindle power for speed and a narrow, long machine.

Frequently Asked Questions
01
Both modes are listed. Z travel is 52 mm (2.0 in) with a fixed headstock and 130 mm (5.1 in) with a sliding headstock, and the maximum turning length is 130 mm (5.1 in). Sliding operation is the one to use for slender parts that need support close to the cut.
02
4 turrets with 8 live TRAUB KPS36 stations each, W serration. Live tools run to 12,000 rpm, rated 1.0 / 2.6 kW and 2.7 / 7.6 Nm at 100% / 25% duty. Turret travel is X 43 mm (1.7 in), Z 52 mm (2.0 in) and Y ±8°, and 0, 2 or 4 flex tool carriers can be added.
03
2 or 4 counter spindles, each running to 15,000 rpm and rated 5.1 / 5.4 kW (6.8 / 7.2 hp) at 100% / 40% duty, with 3.1 Nm (2.3 lb-ft) at 100% duty. They travel X 128 mm (5.0 in) and Z 152 mm (6.0 in).
04
The TRAUB TX8i-s V8 with dual NCU, operated from a 19-inch touchscreen with iXpanel. The C-axis resolution is 0.001°, which matters for indexed cross holes and milled flats on the small parts this machine is built for.
05
Floor space of 5,778 x 1,716 mm (227.5 x 67.6 in) with 2,404 mm (94.6 in) of height, and 65 kW / 76 kVA, 125 A of supply. Fully equipped it weighs 8,000 kg (17,637 lb), excluding the coolant system and chip conveyor, which come on top.
