Hurco TM10i

The Hurco TM10i is a turning center for parts up to 450 mm (17.72 in) in diameter and 758 mm (29.84 in) long, with a 260 mm (10.24 in) chuck, 81 mm (3.19 in) bar capacity and a 3,000 rpm spindle that delivers 350.8 Nm (258.78 ft-lb) from 22 kW (29.5 hp). Travels are 250 mm (9.84 in) on X and 790 mm (31.1 in) on Z.

Its spindle figures are worth reading closely next to the TM8i. The TM10i has slightly less power, 22 kW against 23.2 kW (31.11 hp) on the TM8i, but about 58% more torque, and its top speed is 3,000 rpm against 4,000 rpm. That is the profile of a machine meant to pull heavier cuts on larger diameters at lower spindle speeds, where torque rather than power sets the limit. For high-speed work on small diameters it is the wrong size.

The envelope is the main reason to choose it. Turning length grows to 758 mm and distance between centers is 744 mm (29.29 in), so shafts and long chucked parts that would not fit the TM8i's 525 mm (20.67 in) length fit here. Swing over the bed is 582 mm (22.91 in) and over the cross slide 402 mm (15.83 in).

The TM10i is the turning-only member of its group. The TM10Mi adds driven tools at 4,000 rpm and a 40 kW (53.64 hp), 520.2 Nm (383.99 ft-lb) spindle, but turns only to 295 mm (11.61 in). The TM10MYi adds a 55 mm (2.17 in) Y axis and turns to 400 mm (15.75 in). The 12-station turret on the TM10i takes 25 mm x 25 mm shanks and boring bars up to 40 mm (1.57 in). Both axes rapid at 30 m/min (1,181 ipm), and the machine weighs 5,014 kg (11,054 lb). Control is Hurco's WinMax, with conversational and NC programming.
