Hurco TMX8MYi vs Hurco TMX8MYSi
Hurco vs Hurco · Mill-Turn Machines
Summary
The Hurco TMX8MYi and Hurco TMX8MYSi are the same 8-inch class Y-axis mill-turn machine, with and without a sub-spindle. Every published capacity is shared: 285.5 mm (11.24 in) of X travel, 55 mm (2.17 in) of Y, 560 mm (22.05 in) of Z, a 274.6 mm (10.81 in) turning diameter, 527 mm (20.75 in) turning length, 64.5 mm (2.54 in) bar, a 4,500 rpm spindle with 25 kW (33.5 hp) and 238.7 Nm (176.1 ft-lb) and 12 tools.
The difference is in the axes. The TMX8MYSi lists X, Z, Y, Z2, C1 and C2, so a sub-spindle can pick off the part and machine its back end in the same cycle. The TMX8MYi lists X, Z, Y, W and C. The table gives the TMX8MYi as 7,500 kg (16,535 lb) and the TMX8MYSi as 7,255 kg (15,994 lb).

Advantages
Hurco TMX8MYi
- Single-spindle layout with a W axis (X, Z, Y, W, C) for parts machined from one side
- Same 4,500 rpm, 25 kW (33.5 hp) spindle and 64.5 mm bar capacity as the sub-spindle model
Hurco TMX8MYSi
- Sub-spindle with Z2, C1 and C2 axes for front and back machining in one cycle
- Removes manual part flipping and second-operation setups on bar-fed work
- Listed at 7,255 kg (15,994 lb) against 7,500 kg (16,535 lb)
Verdict
Buy the Hurco TMX8MYSi when parts need features on both ends: implants, firearms actions, bolt carriers and aerospace fittings that should come off the machine complete, often bar-fed and unattended. Buy the Hurco TMX8MYi for job-shop, prototype and firearms work where parts are finished from one side or a second operation is acceptable, since capacity and spindle are otherwise identical.
