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 HQR-250MSY-850U is
The Mazak HQR-250MSY-850U 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 / 344 mm. This one is specified with a Y axis, live tooling and a sub-spindle: off-center milling without a second setup; driven tools in the turret or milling spindle; the part transfers and is finished on the back end.
What it is built to do
From the figures the manufacturer publishes, a Mazak HQR-250MSY-850U suits:
- parts finished on the back end without a second setup (second spindle, 5000 rpm)
- drilled, tapped and milled features on a turned part (rotary-tool upper turret, 6000 rpm)
- off-center features, on 4.00 in / 100 mm of Y travel

These are the manufacturer’s figures for this model as currently published. A machine built years ago may differ in control generation and in options, which is exactly why the questions below matter when you sell one.

What fits a Mazak HQR-250MSY-850U
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.

Mazak HQR-250MSY-850U 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 2 independent sources. 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 HQR-250MSY-850U
The same list whichever side of the deal you are on.
- Control generation. The manufacturer specifies SmoothG 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.
