WHY CHOOSE MAZAK QTN400M-II 2016

The MAZAK QTN400M-II – 2016 is an attractive choice for manufacturers that need a heavy-duty CNC turning center with integrated milling capability. Unlike a conventional 2-axis CNC lathe, the M configuration provides live tooling and C-axis functionality, allowing multiple machining operations to be completed in one setup.

Its 50 HP main spindle provides the power necessary for demanding turning operations, while the 4,000 RPM live-tool spindle provides additional capability for drilling, tapping, milling, and slotting. The 15-inch chuck and approximately 4-inch bar capacity also make the machine suitable for larger workpieces.

Another advantage is the MAZATROL Matrix Nexus 2 control, which provides conversational programming capabilities along with conventional CNC programming. The machine’s large swing, long machining envelope, and 12-position live-tool turret make it versatile for both production and job-shop applications.

For manufacturers that regularly machine large components, the QTN400M-II can provide substantial productivity without requiring separate machines for every turning and secondary milling operation.

WHY BUY USED MAZAK QTN400M-II 2016

Buying a used MAZAK QTN400M-II 2016 can provide access to a high-capacity production turning center at a significantly lower acquisition cost than a new machine with comparable spindle power and work envelope.

The QTN400M-II is particularly attractive to shops that need to machine large parts but also require milling and drilling capabilities. The combination of a 50 HP spindle, 15-inch chuck, 4-inch bar capacity, C-axis, live tooling, and MAZATROL Matrix Nexus 2 control gives the machine a broad range of production applications.

A used machine should be inspected carefully before purchase. Buyers should check spindle condition, chuck operation, turret indexing, live-tool spindle condition, C-axis accuracy, ball screws, guideways, tailstock alignment, hydraulic system, coolant system, chip conveyor, electrical cabinet, and CNC control.

Machine hours and maintenance history are also important. A well-maintained QTN400M-II with good geometric accuracy, low spindle hours, complete live tooling, chip management, and documented service history can command considerably more than a machine sold strictly as-is.

HOW MUCH DOES A USED MAZAK QTN400M-II 2016 COST?

The value of a used MAZAK QTN400M-II – 2016 depends heavily on spindle hours, machine condition, bed length, tooling, chuck configuration, tailstock, chip conveyor, coolant equipment, and maintenance history. A current 2016 example is listed as a used machine in good condition with a 15-inch chuck, 4-inch bar capacity, 50 HP spindle, Matrix Nexus 2 control, live tooling, and approximately 20,300 lb machine weight, although the seller does not publish an asking price.

For a 2016 machine, a practical used-market estimate can be divided into several condition categories:

Machine Condition	Estimated Used Price
As-Is / High Hours	$45,000-$60,000
Running / Average Condition	$60,000-$75,000
Good Production Condition	$75,000-$90,000
Excellent Condition / Well Equipped	$90,000-$110,000
Low-Hour / Exceptional Condition	$110,000+

A reasonable target range for a clean, operational 2016 MAZAK QTN400M-II with the MAZATROL Matrix Nexus 2 control, 15-inch chuck, 4-inch bar capacity, 50 HP spindle, live tooling, C-axis, 12-position turret, and supporting equipment would be approximately $70,000-$95,000 USD.

The final selling price should be adjusted for spindle hours, tooling package, chip conveyor, coolant system, tailstock, automatic tool presetter, machine accuracy, service records, and overall cosmetic and mechanical condition.

Best estimated listing value: $80,000-$95,000 USD for a good, operational and properly equipped 2016 MAZAK QTN400M-II.
