The 2011 Mazak QTN-450MY brings powerful multi-tasking to heavy-duty turning. With 125-inch centers, a 33-inch swing, and a hydraulic 17.5-inch chuck on a 50-horsepower, 2000 RPM spindle, it handles large components with precision. Paired with Mazatrol Matrix 2 CNC, 6 live tools, Y-axis milling, and semi-automatic tailstock and steady rest, it integrates complex machining in a single setup. Compared to the lower-spec Mazak QTN-450II, which lacks Y-axis milling and has only static tooling, the QTN-450MY adds significant versatility. It supports driven tooling up to 4000 RPM and includes a hydraulic steady rest and tailstock—making it a more flexible solution for advanced multi-axis production tasks.
