Hurco TMX8MYSi

The Hurco TMX8MYSi is a done-in-one turning center: a 210 mm (8.27 in) main spindle of 25 kW (33.5 hp), a sub-spindle rated 6,000 rpm, 15 kW (20.1 HP) and 102.2 Nm (75.4 lb-ft), 55 mm (2.17 in) of Y travel and 5,000 rpm driven tools on a 12-station BMT65 turret. It turns up to 274.6 mm (10.81 in) in diameter and 527 mm (20.75 in) long.

The sub-spindle is the whole point of this model. A part finished on the main side is handed over and its back face drilled, tapped, milled or turned without an operator re-chucking it. For bar-fed parts that need work on both ends, that removes a second setup and the error that comes with it. The sub-spindle runs faster than the 4,500 rpm main spindle, which suits the smaller back-side features most parts carry, but its 102.2 Nm (75.4 lb-ft) is well below the main spindle's 238.7 Nm (176.1 ft-lb), so heavy cuts belong on the main side.

Everything else matches the TMX8MYi: 285.5 mm (11.24 in) of X, 560 mm (22.05 in) of Z and 640 mm (25.2 in) on the W axis, 754 mm (29.68 in) between centers, and 508 mm (20 in) of swing. The listed weight is 7,255 kg (15,994 lb), against 7,500 kg (16,535 lb) for the TMX8MYi; confirm the figure with Hurco before planning the foundation, since the machine with the extra spindle is listed as the lighter one.

Driven tools are rated 6.3 kW (8.5 HP) and 27.6 Nm (20.4 lb-ft). Bar capacity is 64.5 mm (2.54 in), turning shanks are 25 mm x 25 mm, and boring bars go up to 40 mm (1.57 in). Programming runs through Hurco's WinMax control, conversational or NC.
