Our best estimate for the Mazak QT-Ez 12MY is $115,000 - $170,000. This is an estimate for a cnc lathes / turning centers in this class, not a quote from Yamazaki Mazak; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/mazak-qt-ez-12my#price; the request is passed to Yamazaki Mazak or an authorised dealer.
The table lists 4 in (102 mm) of Y travel. A Y-axis moves the tool off the spindle centreline in a straight line, which is how flats, keyways and off-centre holes are machined to size on a lathe. The table lists no rotary-tool speed or power for this model, so confirm those figures with Mazak.
Both list 4 in (102 mm) of Y travel, 9 in (229 mm) of X, 24 in (610 mm) of Z and Ø3 in (76 mm) bar capacity. The QT-Ez 12MY has a 12 in chuck and a turning length of 19 in (483 mm). The QT-Ez 10MY belongs to the smaller chuck group and lists 20 in (508 mm) of turning length and 12 tools.
Top speed is 3,300 rpm and the spindle motor is listed at 22 kW (30 HP) (30 min. rating). Mazak's table gives no continuous rating and no torque figure. The 3,300 rpm limit suits large diameters; small-diameter work will run below the ideal surface speed.
Maximum turning diameter is Ø14 in (356 mm) and maximum turning length 19 in (483 mm), with a swing of Ø27 in (686 mm) and Ø3 in (76 mm) bar capacity. The plain QT-Ez 12 turns Ø16 in (406 mm) by 21 in (533 mm) but lists no Y travel.
