Our best estimate for the Mazak QT-COMPACT 300M is $100,000 - $160,000. 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-compact-300m#price; the request is passed to Yamazaki Mazak or an authorised dealer.
The listed bar capacity is 80 mm (3.15 in), through an A2-8 spindle nose with a 10 in chuck. The QT-COMPACT 200M listing passes 52 mm (2.05 in) through an A2-6 nose, so the 300M is the size to look at for larger bar.
The listed table has X and Z travel rows only: 210 mm (8.27 in) and 550 mm (21.65 in). Live tooling is listed at 6,000 RPM and 5.5 kW (7.4 hp) on a 12-station BMT turret, so drilling and milling are possible on the centreline but not off it.
The listed weight is 4,800 kg (10,582 lb). The QT-COMPACT 200M is listed at 3,500 kg (7,716 lb). Confirm the weight on the machine's plate before arranging transport, because this is a listed figure for a model Mazak no longer shows, not one read off the machine.
Mazak's current lineup does not include a model under this name, so it is a possible older model. Anyone considering one should treat the listed figures, such as 18.5 kW (25 hp) at 4,000 RPM, as a guide and verify them from the machine's own documentation.
