Hurco TM8i vs Hurco TM8Mi
Hurco vs Hurco · CNC Lathes
Summary
The Hurco TM8i is listed as a turning center and the Hurco TM8Mi as a mill-turn machine, so they serve different jobs on a shared base. Both have 550 mm (21.65 in) of Z travel, 64.5 mm (2.54 in) bar capacity, a 210 mm (8.27 in) chuck, a 4,000 rpm A2-6 spindle, 12 tools, 30 m/min rapids and 597 mm (23.5 in) between centers.
The TM8i swings the larger part, 356 mm (14.01 in) against 256 mm (10.08 in), and turns slightly longer at 525 mm (20.67 in) against 497 mm (19.57 in). Spindle power is close, 23.2 kW (31.11 hp) against 22.6 kW (30.3 hp). The TM8Mi has more torque, 264.1 Nm (194.82 ft-lb) against 221.5 Nm (163.41 ft-lb), and adds live tooling for cross-holes and flats.

Advantages
Hurco TM8i
- 356 mm (14.01 in) turning diameter against 256 mm (10.08 in)
- 525 mm (20.67 in) turning length against 497 mm (19.57 in)
- Lighter machine at 4,030 kg (8,885 lb) against 4,400 kg (9,700 lb)
Hurco TM8Mi
- 264.1 Nm (194.82 ft-lb) torque against 221.5 Nm (163.41 ft-lb)
- Mill-turn design for cross-holes, flats and tapped holes in one setup
Verdict
Choose by the features on the part. The Hurco TM8i is the better buy for pure OD, ID, grooving and threading work up to 356 mm in diameter, and for training rooms that only need turning. The Hurco TM8Mi suits hydraulic fittings, medical parts and other turned work under 256 mm in diameter that needs radial holes and flats done in the lathe instead of on a VMC.
