How much does the Hurco TM12Mi cost?
Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Hurco. Configuration moves it a long way.
Overview
The Hurco TM12Mi is a larger machine than the TM8Mi and TM10Mi live-tool turning centers: a 315 mm (12.4 in) chuck, 104 mm (4.09 in) bar capacity, and a 40 kW (53.64 hp) spindle that produces 743.7 Nm (548.56 ft-lb) up to 2,800 rpm. It turns up to 360 mm (14.17 in) in diameter and 937 mm (36.89 in) in length, with 1,006 mm (39.6 in) between centers.
The 104 mm (4.09 in) bore is what sets it apart. Bar stock up to that size, for parts such as large fittings, hydraulic components and couplings, can be fed through the spindle rather than sawn into blanks. The torque figure supports it: 743.7 Nm (548.56 ft-lb) is enough to rough big-diameter steel at the low speeds such parts call for.
Against the TM12i, which takes the same chuck and lists no live tooling, the comparison is unusual. The TM12i has the bigger motor, 55 kW (73.76 hp), but lower torque at 604.9 Nm (446.17 ft-lb), and it turns larger: 510 mm (20.08 in) by 1,000 mm (39.37 in). The TM12Mi gives up some envelope for driven tools and more low-speed torque, and both weigh 7,500 kg (16,535 lb).
The live stations run to 4,000 rpm with 10 kW (13.41 HP) and 63.7 Nm, enough for drilling, tapping and milling flats on large parts. The turret is built for heavier tooling than on the TM10Mi: 32 mm x 32 mm shanks and boring bars up to 50 mm (1.97 in). Travels are 305 mm (12 in) on X and 1,016 mm (40 in) on Z at 30 m/min (1181 ipm), with 680 mm (26.77 in) swing over the bed and 510 mm (20.08 in) over the cross slide. Control is Hurco WinMax, conversational plus NC.

Strengths & Limitations
Strengths
- 104 mm (4.09 in) bar capacity on a 315 mm (12.4 in) chuck
- 743.7 Nm (548.56 ft-lb) from a 40 kW (53.64 hp) spindle, more torque than the TM12i
- 937 mm (36.89 in) turning length and 1,006 mm (39.6 in) between centers
- 32 mm x 32 mm turret shanks and boring bars up to 50 mm (1.97 in)
- Live tooling to 4,000 rpm rated 10 kW (13.41 HP) and 63.7 Nm
Limitations
- Turning diameter is 360 mm (14.17 in), against 510 mm (20.08 in) on the TM12i
- 2,800 rpm spindle ceiling limits surface speed on smaller diameters
- No Y travel is listed, so milled features must sit on the centerline or use C-axis work
- 7,500 kg (16,535 lb) needs a foundation and rigging plan

Frequently Asked Questions
01
Both take a 315 mm (12.4 in) chuck, run to 2,800 rpm and weigh 7,500 kg (16,535 lb). The TM12Mi adds 4,000 rpm live tooling and 743.7 Nm (548.56 ft-lb) of torque. The TM12i has 55 kW (73.76 hp) and 604.9 Nm (446.17 ft-lb) and turns 510 mm (20.08 in) by 1,000 mm (39.37 in).
02
104 mm (4.09 in). With a 315 mm (12.4 in) chuck and 743.7 Nm (548.56 ft-lb) of spindle torque, the machine is suited to large-diameter bar work fed through the spindle rather than chucked blanks.
03
The driven tools run to 4,000 rpm and are rated 10 kW (13.41 HP) with 63.7 Nm of torque. That suits drilling, tapping and milling flats or slots on large turned parts.
04
X travel is 305 mm (12 in) and Z travel 1,016 mm (40 in), both at 30 m/min (1181 ipm). The 12-station turret takes 32 mm x 32 mm shanks and boring bars up to 50 mm (1.97 in) in diameter.
