Available at Auction 07/16/2025 The 2007 Mazak QTN-350-II is a twelve-inch-chuck turning centre that stretches 26.77-inch swing and 16.54-inch cutting diameter across a 62.8-inch bed, giving job-shops big-bore capacity in a footprint under 170 inch by 81 inch. A 4-inch bar slips through the 2.99-inch spindle bore, and the built-in 40 HP motor holds 4000 RPM for aluminium or 750 foot-pound torque at 350 RPM for Inconel roughing. Mazatrol Matrix conversational control speeds setup with pictorial cycles, and X 10.13-inch by Z 82.5-inch travels race home at 1181 IPM to minimise non-cut time. Flood coolant and a roof-mounted mist collector clear chips and vapour, while a tailstock steadies shafts to 62.72-inch centres for one-and-done machining. Compared with the QTN-250-II that ships with an 8-inch chuck, 2.52-inch bar and 30 HP spindle, the QTN-350-II widens the bore to 4 inch, boosts continuous power to 40 HP and lengthens Z-stroke past 80 inch—transforming a light-duty shop lathe into a production powerhouse without increasing programming complexity because both machines share Mazatrol Matrix code.
