What the maker publishes about the current Makino A81NX

Makino's a81nx is a horizontal machining center built around a 630 mm pallet. Strokes are 900 mm in X, 900 mm in Y and 1,020 mm in Z, and the table rotates 360 degrees as the B axis. The largest workpiece is ø1,000 mm by 1,300 mm, and the maximum payload is 1,200 kg, with 1,500 kg listed as an option. The standard spindle turns 10,000 rpm on a CAT50 taper; a high torque spindle at 8,000 rpm and an HSK-A100 taper are optional. Rapid traverse and cutting feed are both 50,000 mm/min, or 36,000 mm/min with the high torque spindle. The magazine holds 60 tools, with 80, 136, 187 or 299 optional. Tools can reach 690 mm long, 356 mm across and 30 kg. A tool change takes 1.7 seconds tool to tool and 3.7 seconds chip to chip. Makino states that 100 mm of additional Y stroke, together with changes to the table and column castings, gives this model 12.5% more work envelope than its predecessor.

Makino A81NX specifications

Manufacturer specification. Every figure below was read from the manufacturer’s own published specification for this machine and checked back against that document word for word.

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.

Derived from Spindle taper: CAT50 (HSK-A100 opt)

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.

Derived from Pallet size: 630 mm x 630 mm

What to check on a Makino A81NX

Spindle. The manufacturer gives a spindle speed of 10,000 (8,000 High Torque opt). Run the spindle to top speed and listen for bearing noise.
Axes and way covers. The manufacturer gives X 900 mm, Y 900 mm and Z 1,020 mm of travel. Run each axis end to end and check the way covers.
Tool changer. The manufacturer gives the tool capacity as 60 (80, 136, 187, 299 opt). Cycle every pocket and watch for a hesitation.
Pallet changer. The manufacturer gives a pallet size of 630 mm x 630 mm. Run a full pallet change, and count the pallets and fixtures that come with the machine.
