2012 MAZAK QTN250M CNC LATHES

Technical Description

The Mazak Quick Turn Nexus 250M (QTN250M) is a slant-bed CNC turning center with rotary milling tools, part of Yamazaki Mazak's Quick Turn Nexus series built from the early 2000s and later updated as the 250-II M. It is sized for medium-diameter chucking and bar work and combines turning, milling, drilling and tapping in one setup through full C-axis contouring on the main spindle. The single main spindle carries a 10 in chuck on an A2-8 nose, runs to 4,000 rpm and is driven by an integral motor rated 35 hp (26 kW, 30-minute rating). A 12-station drum turret accepts rotary tools in every position, with the milling spindle rated 7.5 hp and 4,500 rpm as standard. Maximum swing is 26.5 in and standard bar capacity is 3 in. The machine was offered with different bed lengths, so maximum machining length depends on the version. Controls are from the Mazatrol Nexus family (Mazatrol Fusion 640T Nexus on early machines, Mazatrol Matrix Nexus and Matrix Nexus 2 on later ones), with conversational and EIA/ISO programming. Typical equipment includes a programmable tailstock, automatic tool eye, chuck open/close confirmation and chip conveyor.
