How much does the Onsrud 277G 5-Axis cost?
Price estimate
We do not have a price for the Onsrud 277G 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
Buyers of the Onsrud 277G 5-Axis should read the maker's table closely, because it gives two table lengths for the one code. In the 16 in (406 mm) Z-stroke block the table X is 289 in (7,341 mm). In the 18 in (457 mm) block it is 277 in (7,036 mm). Table Y is 61 in (1,550 mm) in both.
The figures are carried here as Onsrud prints them, in inches and millimetres alike. The 16 in row matches the 289G of the 3-axis table, and the 18 in row matches the model code. Which is right for a given order is a question for the quotation, and it matters if a fixture or a part is close to twenty-four feet long.
The frame follows the stroke as well: 383 in (9,729 mm) long and 103 in (2,617 mm) high with 16 in of Z, 379 in (9,627 mm) long and 140 in (3,556 mm) high with 18 in. Width is 136 in (3,455 mm). Eight vacuum zones are listed for both, one more than the longer 333G 5-Axis shows, which is a second figure to confirm.
Set those questions aside and the machine is clear enough. It is a long 5-axis moving-gantry router with a shallow stroke, an 18 hp (13.4 kW), 24,000 rpm spindle and 12 tools, built for trimming and edge-machining long, low parts in composites, aluminum, foam or wood.

Strengths & Limitations
Strengths
- Table X of 277 in (7,036 mm) or 289 in (7,341 mm), depending on the Z-stroke block
- 8 vacuum zones listed as standard
- Two Z-strokes: 16 in (406 mm) and 18 in (457 mm)
- Frame width of 136 in (3,455 mm)
Limitations
- The maker's table gives two different table lengths for this code
- The zone count is out of step with the next size up
- Shallow strokes: this is not a deep-part machine

Frequently Asked Questions
01
Onsrud's table shows 289 in (7,341 mm) in the 16 in Z-stroke block and 277 in (7,036 mm) in the 18 in block. The millimetre table repeats both figures. Confirm the table length for the chosen stroke before ordering.
02
With the 16 in stroke: 383 in (9,729 mm) long, 136 in (3,455 mm) wide, 103 in (2,617 mm) high. With the 18 in stroke: 379 in (9,627 mm) long, 136 in (3,455 mm) wide, 140 in (3,556 mm) high.
03
8 are listed as standard for both strokes. The 333G 5-Axis, a longer machine, lists 7, so the figure does not follow the usual pattern and is worth checking with the maker.
04
Onsrud positions the G-Series 5-Axis for large parts found in the aerospace, marine and automotive industries. With a 16 in or 18 in Z-stroke, the 277G 5-Axis fits the long, shallow end of that range.
