How much does the Onsrud 408G cost?
Price estimate
We do not have a price for the Onsrud 408G 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 408G ends the tall-stroke run of five-foot-wide G-Series tables. Its bed is 408 in (10,364 mm) long, thirty-four feet, by 61 in (1,550 mm) wide, and the Z-stroke is 28 in (711 mm).
There is a jump before it. The 312G has a table of 312 in (7,925 mm) and 7 zones. The 408G adds eight feet and lists 9 zones, with no size in between. So this is the model for work that is truly long: spars, rails, building components, or a row of tall fixtures loaded and unloaded in sequence while the machine keeps cutting.
A frame 515 in (13,081 mm) long is a building project. It is also 155 in (3,937 mm) high and 142 in (3,607 mm) wide. Foundation, power drops and dust collection all have to follow the gantry down the bed. Settle those with the maker before the floor is poured.
One 18 hp (13.4 kW), 24,000 rpm spindle with 12 tools is the standard head. The series allows up to 4 spindles and a second gantry. For a single long part, Onsrud describes parking one gantry and letting the other machine end to end. For batches of shorter parts, two gantries can work in tandem.

Frequently Asked Questions
01
The table is 408 in (10,364 mm) in X, which is thirty-four feet, and 61 in (1,550 mm) in Y. The Z-stroke is 28 in (711 mm), so the part can also be thick or sit on a fixture.
02
9 as standard. Along a 408 in (10,364 mm) table that lets separate sections be switched on for the area being cut and released where parts are being removed.
03
The 420G, which has a longer table, 428 in (10,872 mm), with 11 in or 18 in of Z, and the same 9 vacuum zones. The 420G frame is 136 in (3,455 mm) wide against 142 in (3,607 mm) for the 408G.
04
515 in (13,081 mm) long, 142 in (3,607 mm) wide and 155 in (3,937 mm) high. In round terms that is forty-three feet of machine, so the building, not the router, usually sets the limit.
