Advantages
Hurco TM8Mi
- 22.6 kW (30.3 hp) spindle against 18 HP (13.2 kw)
- 64.5 mm (2.54 in) bar capacity against 2.04 in (52 mm)
- 497 mm (19.57 in) turning length against 17.9 in (455 mm)
Hurco TMM8
- 4,800 RPM spindle against 4,000 rpm
- Lighter machine at 8,819 lb (4,000 kg) against 4,400 kg (9,700 lb)
Verdict
Both handle turned parts with cross-holes and flats, so the choice rests on stock size and power. The Hurco TM8Mi suits hydraulic fittings and job-shop parts cut from bar up to 64.5 mm, where 22.6 kW handles steel and longer parts. The Hurco TMM8 fits smaller medical, connector and prototype parts from 52 mm bar or less, where its 4,800 RPM spindle helps on small diameters.
