How much does the Onsrud 289G cost?
Price estimate
We do not have a price for the Onsrud 289G 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 289G stretches the five-foot-wide G-Series table to 289 in (7,341 mm) in X, twenty-four feet and an inch, on the usual 61 in (1,550 mm) of Y. Two twelve-foot sheets fit end to end. So does a single long extrusion bed or a row of fixtures for plate work.
One row of Onsrud's table stands out for this model. The 289G is listed with 8 vacuum zones as standard, more than the longer 333G, which shows 7. The figure is the same in the inch and millimetre tables, so it is carried here as printed, but it is out of step with the sizes on either side and should be confirmed with the maker. Eight zones would suit pendulum work well: four per half.
The frame is 136 in (3,455 mm) wide. Length and height depend on the Z-stroke. Onsrud gives 383 in (9,729 mm) and 103 in (2,617 mm) for the 11 in (279 mm) stroke, and 379 in (9,627 mm) and 140 in (3,556 mm) for the 18 in (457 mm) stroke.
Standard equipment is one 18 hp (13.4 kW) spindle at 24,000 rpm and a 12-tool capacity. At this length a dual gantry starts to make sense. Onsrud describes two gantries working in tandem on similar parts, or one parked while the other machines a long part end to end.

Frequently Asked Questions
01
Onsrud's table lists 8 as standard, in both its inch and millimetre versions. The 241G below it lists 5 and the 333G above it lists 7, so the number breaks the pattern. Treat it as a figure to confirm on the quotation.
02
289 in (7,341 mm) in X by 61 in (1,550 mm) in Y. That is long enough for two twelve-foot sheets end to end, or three eight-foot sheets, on a table one sheet wide.
03
It is 383 in (9,729 mm) long and 103 in (2,617 mm) high with the 11 in Z-stroke, or 379 in (9,627 mm) long and 140 in (3,556 mm) high with the 18 in Z-stroke. Width is 136 in (3,455 mm) for both.
04
Not under the 289G code. The 28 in block of Onsrud's table lists the 265G instead, with a 265 in (6,731 mm) table, a 142 in (3,607 mm) frame width and a machine height of 155 in (3,937 mm).
