Takamaz XTT-500M

The Takamaz XTT-500M is the live-tool version of the XTT-500 shaft lathe. It has two 8-station turrets, with 4 live tools on one side running at 4,000 rpm and rated to drill Ø10 mm and tap M4 to M8, plus 105 mm (4.1 in) of X, 450 mm (17.7 in) of Z, an 8 in collet and a 15 / 11 kW spindle to 4,000 rpm. Workpieces are listed from 25 to 70 mm in diameter, up to 400 mm long and up to 8.0 kg.

The live tools change what a shaft needs after it leaves the lathe. A cross-hole for a pin, a tapped hole in the end face or a small drilled feature can be done in the same chucking, instead of on a drilling machine with its own fixture. The capacity is modest: Ø10 mm drilling and M4 to M8 tapping, on 4 stations of one turret. Larger holes, heavier threads and milled flats are outside it, and the table lists no Y axis, so the driven tools work on the centre line.

With the live tools on one turret, the other turret's 8 stations stay free for turning, so the two-turret layout still lets roughing and finishing tools share the cutting on the shaft. The 105 mm X and 450 mm Z strokes and the 25 to 70 mm diameter range point to the same slender work as the base machine: shafts, axles, pins and tubes. Rapids are 18 m/min on X and 24 m/min on Z, and the machine stands on 1,695 × 1,830 mm (W × L).

Unlike the XTT-500, which lists an 18.5 / 15 kW spindle, a Ø120 mm bearing, a 10 in chuck and a 3,500 rpm spindle as options, the XTT-500M table gives a single fixed specification: 15 / 11 kW, Ø100 mm bearing, 8 in collet and 4,000 rpm.
