Price estimate
We do not have a price for the Onsrud 456GW12 5-Axis that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Onsrud 456GW12 5-Axis is the largest deep-stroke machine in Onsrud's G-Series 5-Axis table. The table is 456 in (11,583 mm) in X by 144 in (3,658 mm) in Y, thirty-eight feet by twelve, and the Z-stroke is 28 in (711 mm) or 40 in (1,016 mm).
The two strokes are two frames. With 28 in of Z the machine is 571 in (14,504 mm) long and 155 in (3,937 mm) high, with 10 vacuum zones. With 40 in of Z it is 602 in (15,291 mm) long and 167 in (4,242 mm) high, with 11 zones. Width is 224 in (5,690 mm) for both. A buyer choosing the taller stroke should budget more than two extra feet of length as well as the extra height.
This is the size for one-piece hull plugs and deck moulds for yachts, for full-length tooling in aerospace, and for the largest patterns in transport. A thirty-eight-foot part twelve feet wide is beyond what most shops can move, so the machine is usually sited where the part is built and the part stays on the bed through roughing, finishing and inspection.
The standard head is modest for the envelope: 18 hp (13.4 kW), 24,000 rpm, 12 tools. The 33 hp (24.6 kW) spindle, a second gantry and a second tool changer are all listed, and Onsrud recommends laser compensation and linear scales for tight tolerances.

Frequently Asked Questions
01
The table is 456 in (11,583 mm) by 144 in (3,658 mm). The 28 in version is 571 in (14,504 mm) long, 224 in (5,690 mm) wide and 155 in (3,937 mm) high. The 40 in version is 602 in (15,291 mm) long, 224 in (5,690 mm) wide and 167 in (4,242 mm) high.
02
Onsrud's table shows 10 vacuum zones in the 28 in block and 11 in the 40 in block for the same table size. The page does not explain it. Confirm the zone layout for the version being ordered.
03
In table X, yes: the 480GW12 5-Axis lists 480 in (12,192 mm), but only with 16 in or 18 in of Z. Among the deep-stroke models nothing in the chart is larger.
04
Onsrud recommends laser compensation and linear scales (encoders) for applications with tight tolerances, and offers devices that measure tool height, width and wear. On a table 456 in (11,583 mm) long, both belong in the specification for tooling work.
