How much does the Onsrud 300G 5-Axis cost?
Price estimate
We do not have a price for the Onsrud 300G 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 300G 5-Axis has a table exactly twenty-five feet long: 300 in (7,620 mm) in X, by 61 in (1,550 mm) in Y. It belongs to the 28 in (711 mm) block of Onsrud's G-Series 5-Axis table and has 7 vacuum zones as standard.
One comparison shows how the 5-axis head affects the machine. The 3-axis 312G has the same frame, 419 in (10,643 mm) long, with a table of 312 in (7,925 mm). On the 300G 5-Axis the table is a foot shorter. The page does not explain the difference, so ask for the X travel of both if usable length decides the purchase.
A twenty-five-foot deep-stroke table is a tool-room machine for large-part industries. It suits stringer and deck-beam patterns for boat builders, and long trim fixtures and skin tools for aircraft shops. Onsrud names aerospace, marine and automotive work for the series, and at this length the first two are the likely buyers.
The frame is 142 in (3,607 mm) wide and 155 in (3,937 mm) high. Because the gantry may be far from the tool changer, a second 12-position rotary ATC is worth adding. The base spindle is 18 hp (13.4 kW) at 24,000 rpm with 12 tools.

Frequently Asked Questions
01
300 in (7,620 mm) in X, which is twenty-five feet, and 61 in (1,550 mm) in Y. The machine frame is 419 in (10,643 mm) long.
02
Onsrud's tables give the 312G a 312 in (7,925 mm) table and the 300G 5-Axis a 300 in (7,620 mm) table, with the same machine length. The maker does not state the reason, and its tables list table sizes, not axis travels.
03
155 in (3,937 mm). It is 142 in (3,607 mm) wide. Every five-foot-wide model in the 28 in block of the 5-axis table has those two figures.
04
