Hurco TM6i vs Hurco TM8i
Hurco vs Hurco · CNC Lathes
Summary
The Hurco TM6i and Hurco TM8i are two sizes of Hurco's 2-axis turning center, both with 12 tools, 30 m/min (1181 ipm) rapids and WinMax control. The TM8i is the larger and more powerful machine; the TM6i the smaller, faster-spinning one.
The TM8i turns 356 mm (14.01 in) in diameter against 316 mm (12.44 in) and 525 mm (20.67 in) long against 340 mm (13.39 in), takes 64.5 mm (2.54 in) bar against 45 mm (1.77 in) on a 210 mm (8.27 in) chuck, and delivers 23.2 kW (31.11 hp) and 221.5 Nm (163.41 ft-lb) against 13 kW (17.43 hp) and 113.9 Nm (83.99 ft-lb). The TM6i spins to 6,000 rpm against 4,000 rpm and weighs 3,230 kg (7,121 lb) against 4,030 kg (8,885 lb).

Advantages
Hurco TM6i
- 6,000 rpm spindle against 4,000 rpm
- Smaller machine at 3,230 kg (7,121 lb) against 4,030 kg (8,885 lb)
Hurco TM8i
- 525 mm (20.67 in) turning length against 340 mm (13.39 in)
- 64.5 mm (2.54 in) bar capacity against 45 mm (1.77 in)
- 23.2 kW (31.11 hp) and 221.5 Nm (163.41 ft-lb) against 13 kW and 113.9 Nm
- 356 mm (14.01 in) turning diameter against 316 mm (12.44 in)
Verdict
The Hurco TM8i is the more capable general-purpose lathe: shops turning steel and mixed materials up to 525 mm long or from 64.5 mm bar get nearly twice the torque. The Hurco TM6i fits small, high-mix parts under 45 mm bar, such as medical and connector components, prototypes and overflow work, where 6,000 rpm suits small diameters and a compact footprint matters.
