Okuma MU-6300V
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 MU-6300V is
The Okuma MU-6300V is a CNC vertical machining center — a machine for milling, drilling and tapping with a vertical spindle over a table that tilts and rotates, so a part is reached from several faces in one setup. The manufacturer publishes a x-axis travel of 925 (36.42). This one is specified with five-axis motion: the work tilts and rotates, so faces that would need a second setup are reached in one.
What it is built to do
From the figures the manufacturer publishes, a Okuma MU-6300V suits:
- several faces of a part reached in one setup, rather than refixtured between them
- work up to the published 600 (1,320) table rating
- 7/24 taper No.40 <HSK-A63> tooling at up to 10,000 min-1
Okuma MU-6300V 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 fits an Okuma MU-6300V
Each of these follows from a published specification above, which is named beside it.
40-taper toolholders
This is a 40-taper spindle — the 7:24 steep taper that CAT-40, BT-40 and DIN 69871 (SK-40) holders all share. They share the taper and nothing else that matters: the retention knob and the flange form differ between those standards, so holders do not swap between them without changing pull studs. Knowing which standard a machine was tooled for is worth doing before the holders are packed. HSK-A63 is offered as an OPTION on this model, so a given machine may or may not have it. It is a different interface from the taper above, and worth confirming on the machine itself rather than from the model number.

What years the Okuma MU-6300V was built
Across the units we have tracked, build years run from 2015 to 2020. Observed across 25 marketplaces, not a manufacturer build record. The manufacturer specifies OSP-P300MA, so a unit on an older control is an early one or a retrofit.
Okuma MU-6300V 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 4 units of this exact designation on the market, drawn from 4 independent sources, spanning model years 2015 to 2020. 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 MU-6300V
The same list whichever side of the deal you are on.
- Control generation. The manufacturer specifies OSP-P300MA for this model, with OSP-P300SA offered as an option. 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.
- Way covers and the chip auger. Cheap to look at, expensive to ignore — damaged covers are how a way surface gets ruined.
- The tool changer. Count a full carousel change and watch for hesitation.
- A fourth axis or trunnion, if fitted. It is a separate asset and it is counted separately.
- 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.
