Makino MAG.A12/A20H

The Makino MAG.A12/A20H is not one machine size but the long end of the MAG A Series, a family of horizontal 5-axis aerospace machines whose figures are given as maximums. X travel runs up to 20,200 mm (Up to 795.3 in), Y up to 2,500 mm (Up to 98.4 in) and Z up to 650 mm (Up to 25.6 in), on a pallet of up to 20,000 x 2,300 mm (Up to 787.4 in x 90.6 in). Makino's own heading for the page reads MAG A12 - MAG 20.H, which points to lengths from the A12 up to a 20-metre H version.

Because the table gives ceilings rather than one configuration, a buyer has to pin down the exact length and width of the version being quoted. What the table does fix is the largest workpiece, up to 20,000 mm X 2,300 mm x 500 mm (with limitations), and a workpiece weight of up to 10,500 kg (UP to 23,100 lb). That is more than twice the 5,000 kg (11,000 lb) of the MAG.A8 and MAG.A8-H, which matters on parts this long.

The cross-section matches the MAG.A8-H: 2,500 mm Y and 650 mm Z at most, with parts limited to 500 mm (19.7 in) high. The listed workpiece width of 2,300 mm is narrower than the 2,500 mm (98.4 in) that the A8-H lists, so check width as well as length.

The spindle reaches 33,000 rpm, quoted by Makino as a 130kW design, and rapid traverse and cutting feed are both 65,000 mm/min (X, Y, Z). Rotary axes are A at 220° (-110° ~ +110°) and C at 360°. The magazine holds 120 tools, changes in 13 sec tool-to-tool and 20 sec chip-to-chip, and takes HSK tools up to 305 mm (12.0 in) long, 100 mm (3.9 in) across and 8 kg (17.6 lb). An MMC automatic pallet transfer and storage system can be integrated.
