Makino a800Z vs Makino a900Z
Makino vs Makino · 5-Axis Machining Centers
Summary
The Makino a800Z and Makino a900Z are closely related five-axis machining centers. They share 1,200 mm (47.2 in) of Y travel, a 10,000 rpm standard spindle with an optional 8,000 rpm version, 60 tools as standard, and the same tool change and rapid figures. The difference is part size: the a900Z carries an 800 mm (31.5 in) pallet against the a800Z's 630 mm (24.8 in).
The a900Z also adds X travel, 1,400 mm (55.1 in) against 1,280 mm (50.4 in), and a 1,200 kg (2,640 lb) workpiece load against 1000 kg (2,200 lb). It lists two extra-cost options the a800Z does not: a 15,000 rpm spindle and a 185-tool magazine. Z travel is published as overlapping ranges, 1,120 mm - 1,325 mm (44.1 in - 52.2 in) against 1,185 mm - 1,265 mm (46.7 in - 49.8 in), so that row gives neither machine an edge.

Advantages
Makino a800Z
- Sized for parts up to 1000 kg (2,200 lb) on a 630 mm (24.8 in) pallet, when an 800 mm pallet would go unused
- Z range reaching 1,325 mm (52.2 in) at its top end, against 1,265 mm (49.8 in) on the a900Z
Makino a900Z
- 800 mm (31.5 in) pallet against 630 mm (24.8 in)
- 1,400 mm (55.1 in) X travel against 1,280 mm (50.4 in)
- 1,200 kg (2,640 lb) workpiece load against 1000 kg (2,200 lb)
- Optional 15,000 rpm spindle and optional 185-tool magazine; the a800Z lists 60 tools only
Verdict
The Makino a900Z leads on most rows where the two differ, so the choice turns on part size. Choose the Makino a800Z when parts fit a 630 mm (24.8 in) pallet and stay under 1000 kg (2,200 lb). Choose the Makino a900Z for parts up to 1,200 kg (2,640 lb) that need an 800 mm (31.5 in) pallet and 1,400 mm (55.1 in) of X travel, or when a part family needs the optional 185-tool magazine or 15,000 rpm spindle.
