Our best estimate for the Mazak QT-Ez 12M is $95,000 - $145,000. 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-12m#price; the request is passed to Yamazaki Mazak or an authorised dealer.
Surface speed depends on diameter, so 3,300 rpm is ample on large chucked parts and restrictive on small ones. For small-diameter bar work the QT-Ez 10M reaches 4,200 rpm, and the plain QT-Ez 12 reaches 4,000 rpm with the same 22 kW (30 HP) (30 min. rating) motor as the QT-Ez 12M.
The QT-Ez 12 lists 4,000 rpm, a turning envelope of Ø16 in (406 mm) by 21 in (533 mm) and 25 in (635 mm) of Z travel. The QT-Ez 12M lists 3,300 rpm, Ø14 in (356 mm) by 19 in (483 mm) and 24 in (610 mm). Both have a 12 in chuck, 12 tools, Ø3 in (76 mm) bar capacity and a 22 kW (30 HP) (30 min. rating) motor. The table does not list what the M version adds.
22 kW (30 HP) at a 30 min. rating. No continuous rating or torque figure appears in Mazak's table. Because a 12 in chuck machine does much of its work at low spindle speeds, the torque curve is worth requesting before committing heavy roughing jobs.
X travel is 9 in (229 mm) and Z travel 24 in (610 mm), with a Ø27 in (686 mm) swing. Maximum turning diameter is Ø14 in (356 mm), maximum turning length 19 in (483 mm) and bar capacity Ø3 in (76 mm). The turret holds 12 tools.
