Mazak QTU-350 MY
Manufacturer specifications, what it is built to do, the years we have seen them listed, what tooling fits, and what to check on one. MTE also buys them outright.
What the Mazak QTU-350 MY is
The Mazak QTU-350 MY is a CNC turning center — a machine for turning round parts between a chuck and, where fitted, a tailstock — shafts, flanges, housings and bar work. The manufacturer publishes a max turning diameter of 13.500 in / 340 mm. This one is specified with a Y axis, live tooling and bar work: off-center milling without a second setup; driven tools in the turret or milling spindle; a bar feeder can run stock through the spindle.
What it is built to do
From the figures the manufacturer publishes, a Mazak QTU-350 MY suits:
- bar work up to 3.0 in / 77 mm fed through the spindle
- drilled, tapped and milled features on a turned part (rotary tools, 4500 rpm max)
- off-center features, on 4.00 in / 100 mm of Y travel

What fits a Mazak QTU-350 MY
Each of these follows from a published specification above, which is named beside it.
Workholding
A 10-inch chuck. Jaw sets, soft jaws and collet chucks for this size are commodity items, but the chuck itself, and any spare jaws, travel with the machine and are counted in an offer.
Derived from — Chuck size: 10 in / 254 mm
Bar feeder fit
Bar capacity is 77 mm, so a bar feeder for this machine has to be sized for stock up to that diameter. A feeder that comes with the machine is one of the accessories that most changes what a buyer will pay for it.
Derived from — Bar capacity: 3.0 in / 77 mm
What years the Mazak QTU-350 MY was built
The 2 units we have seen listed were all 2020. Observed across 25 marketplaces, not a manufacturer build record. The manufacturer specifies SmoothC, so a unit on an older control is an early one or a retrofit.
Mazak QTU-350 MY machines on the market now
We track listings across 25 used-machinery marketplaces, and every competitor in this market is one of them, so this is a view none of them can produce for themselves. Right now there are 2 units of this exact designation on the market, drawn from 1 source. That is a thin market for this designation, which usually works in a seller’s favor.
We count only listings whose model is spelled as this machine’s own designation. Near spellings that may be a different variant are excluded rather than counted, so this is a floor on what is out there, not a total.
What to check on a Mazak QTU-350 MY
The same list whichever side of the deal you are on.
- Control generation. The manufacturer specifies SmoothC for this model. The control is often the single biggest swing on two otherwise identical machines, because it decides which buyers can use it at all.
- Spindle hours and condition. Most controls show run hours on a maintenance or diagnostics screen. It is the first number anyone asks for, so find it before the conversation rather than during it.
- Tooling and accessories. Holders, chucks, steady rests, probing and automation attachments travel with the machine, and they are worth real money separately from it.
- Turret condition and index time. A turret that has been crashed is the expensive repair on a lathe, and index time is the first thing a buyer times.
- Live tooling and the sub-spindle, if fitted. Whether the rotary tools still drive, and whether the second spindle synchronizes, separates two very different machines that share a model number.
- The tailstock and steady rests. They travel with the machine and they are counted.
- Power and rigging access. How the machine comes out of the building is a real cost, and it is one MTE absorbs, so an accessible machine is worth more to us.
