2016 Mazak QTN-450-II CNC Turning Center

The Mazak Quick Turn Nexus 450-II is a large-capacity CNC turning center with a reputation for the rigidity and reliability that make big-part turning dependable shift after shift. This 2016 machine turns up to 22.83 in in diameter and 38.54 in long, with X/Z travels of 12.2 x 42.12 in, an 18 in 3-jaw hydraulic thru-hole chuck, a 7.3 in bar capacity, and an A2-15 spindle nose driven by a 50 HP motor to 2,000 RPM. It carries a 12-station bidirectional drum turret, a programmable tailstock with 9-level thrust select, high-power through-coolant, a tool eye, a large spindle bore, and a Jorgensen Side 1000U chip conveyor, all under Mazak's Mazatrol Matrix II Nexus control with color LCD, USB, LAN, and MT Connect preparation.

Compared with the original Quick Turn Nexus 450, the 450-II is a meaningful step up rather than a simple refresh. The II generation moves to Mazak's Mazatrol Matrix II Nexus control - a faster processor, larger color display, USB and Ethernet connectivity, and MT Connect readiness the earlier control lacked - paired with refined spindle and feed performance for better finish and cycle times. For a shop buying used, that means the 450-II delivers current-generation control ergonomics and shop-floor connectivity on a proven heavy-turning platform, not just an older machine with a newer badge.
