Makino A81NX
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 Makino A81NX is
The Makino A81NX is a CNC horizontal machining center — a machine for production milling with a horizontal spindle and pallet changer, so one pallet runs while the next is being loaded — chips fall clear and the machine runs unattended. The manufacturer publishes a pallet size of 630 mm x 630 mm. This one is specified with a pallet changer: one pallet runs while the next is loaded.
What it is built to do
From the figures the manufacturer publishes, a Makino A81NX suits:
- one 630 mm x 630 mm pallet cutting while the next is loaded
- work up to the published 1,200 kg (1,500 kg opt) table rating
- CAT50 (HSK-A100 opt) tooling at up to 10,000 (8,000 High Torque opt)
Makino A81NX 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 a Makino A81NX
Each of these follows from a published specification above, which is named beside it.
50-taper toolholders
This is a 50-taper spindle — the 7:24 steep taper that CAT-50, BT-50 and DIN 69871 (SK-50) 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. The manufacturer names CAT for this machine. HSK-A100 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.

Pallets and fixturing
Fixtures, tombstones and spare pallets are cut for a pallet of this size and do not transfer to another machine. On a horizontal they are a large share of what is being sold, so count them before quoting.

What years the Makino A81NX was built
Across the units we have tracked, build years run from 2014 to 2019. Observed across 25 marketplaces, not a manufacturer build record.
Makino A81NX 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 6 units of this exact designation on the market, drawn from 3 independent sources, spanning model years 2014 to 2019. A seller is competing with those units, which is why condition, tooling and control generation decide the number.
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 Makino A81NX
The same list whichever side of the deal you are on.
- Control generation. The specification we hold for this model does not name its control. 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 pallet changer, through a full cycle. A pallet changer that hesitates is the first thing a buyer will find.
- How many pallets and fixtures come with it. On an HMC this is a large part of the number.
- B-axis table condition and backlash, and the chip conveyor, which on a horizontal does real work.
- 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.
