Hurco TM12Mi

The Hurco TM12Mi is the largest mill-turn machine in Hurco's TM (non-TMX) lineup, pairing a 12-inch chuck with C-axis and live tooling for shops that need to complete large turned parts with secondary milling features in a single setup. With 30 kW (40 hp), 104 mm bar capacity, and live tools at 5,000 RPM, it handles heavy turning and cross-drilling operations that smaller mill-turn machines can't reach.

The main spindle delivers 40 hp at up to 2,500 RPM through an A2-8 spindle nose, providing substantial torque for heavy roughing on parts up to 508 mm (20 in) in diameter. Maximum turning length is 635 mm (25 in) with a swing over bed of 711 mm (28 in). The 104 mm (4.1 in) bar capacity opens up bar-fed production for larger-diameter stock.

The 12-station turret accepts live tools at up to 5,000 RPM for cross-drilling, flat milling, radial tapping, and other secondary operations. The programmable C-axis positions the spindle to 0.001 degree for accurate feature placement on large-diameter parts. Like the smaller TM-series mill-turn machines, the TM12Mi does not include a Y-axis.

Travels are 260 mm (10.2 in) in X and 635 mm (25 in) in Z. At approximately 6,000 kg (13,228 lb), the TM12Mi has substantial mass for vibration damping during heavy interrupted cuts on castings and forgings. The hydraulic programmable tailstock supports long shaft work with consistent clamping force.

The WinMax conversational control integrates turning and milling programming in one workflow, making the TM12Mi accessible to operators who don't have CAM programming expertise. For shops producing large flanges, valve bodies, and fittings that need cross-ports, bolt holes, and tapped features, the TM12Mi eliminates the need to transfer parts to a VMC for secondary operations. It competes with the Haas ST-25Y (minus Y), Doosan Puma 3100M, and Mazak QT-300M.
