Makino MAG3.W

The Makino MAG3.W is the wide-Y member of the MAG3 horizontal 5-axis family. It travels 4,000 mm (157.5 in) in X, 1,800 mm (70.9 in) in Y and 1,000 mm (39.4 in) in Z, works on a 3,500 x 1,500 mm (137.8 in x 59.1 in) pallet and runs a 33,000 rpm spindle. The table gives the spindle as 80 kW with 120 kW in brackets; by Makino's convention the bracketed figure is the optional rating, and Makino's introduction quotes the 33,000 rpm – 120kW design, so confirm which motor a given machine carries.

Width is the reason to pick it. The 1,800 mm Y stroke compares with 1,500 mm (59.1 in) on the MAG3.EX, and the largest listed workpiece is 4,000 x 1,800 x 500 mm (157.5 in x 70.9 in x 19.7 in). Parts can therefore use the full Y stroke, but they are limited to 500 mm in height, a long way short of the 1,000 mm Z travel. Workpiece weight is capped at 3,000 kg (6,614 lb).

The trade is pace. Rapid traverse and cutting feedrate are both 25,400 mm/min (1,000 ipm). The MAG3.EX rapids at 62,700 mm/min on X, so on a cycle dominated by long positioning moves the W will be the slower machine. Where the work is wide flat structure that must be reached across its full width, that may matter less than having the Y travel at all.

A ± 110° A axis and a 360° C axis sit behind a compact spindle with a short pivot point, which Makino says gives five-face access and fewer setups. The magazine carries 60 tools as standard with 120 optional, tools up to 90 mm (3.54 in) across and 8 kg (17.6 lb). Tool-to-tool time is 10 sec and chip-to-chip 22 sec. An automatic pallet transfer and storage system in Makino's MMC system can be integrated for unattended running.
