Okuma MULTUS-U4000
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 Okuma MULTUS-U4000 is
The Okuma MULTUS-U4000 is a multi-tasking turn-mill center — a machine for doing turning and milling in one setup — a milling spindle on a B axis working with a main and usually a second spindle, so a part comes off complete. The manufacturer publishes a max turning diameter of Ø650 mm. This one is specified with a Y axis and live tooling: off-center milling without a second setup; driven tools in the turret or milling spindle.
What it is built to do
From the figures the manufacturer publishes, a Okuma MULTUS-U4000 suits:
- drilled, tapped and milled features on a turned part (50 to 12,000)
- off-center features, on 300 (±150) (11.81 (±5.91)) of Y travel
Okuma MULTUS-U4000 specifications
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 years the Okuma MULTUS-U4000 was built
Across the units we have tracked, build years run from 2016 to 2019. Observed across 25 marketplaces, not a manufacturer build record. The manufacturer specifies OSP-P500, so a unit on an older control is an early one or a retrofit.
Okuma MULTUS-U4000 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, spanning model years 2016 to 2019. 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 an Okuma MULTUS-U4000
The same list whichever side of the deal you are on.
- Control generation. The manufacturer specifies OSP-P500 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.
- The milling spindle and its B axis. This is the part of the machine that makes it a turn-mill rather than a lathe, and it is the costliest thing on it to put right.
- Second-spindle synchronization and the parts-catcher or unloader, if fitted.
- Whether the tool magazine is complete. A turn-mill with half its holders missing is a different sale.
- 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.
