Takamaz XT-8MY

The Takamaz XT-8MY is the Y-axis chucker of the XT-8 family: an 8 in collet on a spindle rated 15 / 11 kW and running to 4,000 rpm, a 12-station turret with 12 live tools at 4,000 rpm, and Y travel of +35/-40 mm (+1.38/-1.57 in) alongside 175 mm (6.9 in) of X and 420 mm (16.5 in) of Z. It is built to finish small and medium chucked parts, milled features included, in one setup.

The Y axis is what the other XT-8 models lack. With it, a driven tool can be moved off the part's centre line, so flats, slots, offset holes and pockets can be milled where a lathe without Y could only drill on centre. The live tools are rated to drill Ø20 mm and tap M16, a large enough capacity for real secondary operations on a part of this size, and the table counts 12 live tools on the 12-station turret. Y moves at 10 m/min, slower than the 18 m/min on X and 24 m/min on Z, which is normal for a short milling axis.

The spindle carries the higher of the family's power ratings as standard, 15 / 11 kW, on a Ø100 mm bearing. Loader workpieces are listed up to 150 mm in diameter, 50 mm long and 1.5 kg, so the machine is aimed at flanges, hubs and short bodies rather than long shafts. Floor space is 1,780 × 1,685 mm (W × L).

The XT-8M shares the 420 mm Z stroke, the 12 live tools and the Ø20 mm / M16 capacity, but has no Y axis and lists 190 mm (7.5 in) of X with an 11 / 7.5 kW standard rating. Choose the XT-8MY when parts need off-centre features; when they only need on-centre drilling and tapping, the XT-8M covers it. For longer work the XTL-8MY adds Z travel to 550 mm (21.7 in) with the same Y axis.
