How much does the Onsrud 333G 5-Axis cost?
Price estimate
We do not have a price for the Onsrud 333G 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 333G 5-Axis has a table 334 in (8,484 mm) long and 61 in (1,550 mm) wide and is offered with a 16 in (406 mm) or an 18 in (457 mm) Z-stroke. It is the second longest of the five-foot-wide 5-axis tables with those strokes.
Nearly twenty-eight feet of bed gives a 5-axis router room to do something a short table cannot: hold a row of different fixtures. A stringer jig can sit at one end and a panel fixture at the other, with the 7 standard vacuum zones holding each independently. The head works through one while the next is being loaded.
Onsrud also offers a second gantry on the series. On a table of this length the two gantries have space to work apart. The maker describes running them in tandem on similar parts, or parking one so the other can machine a large part end to end.
Floor space is the price. The machine is 431 in (10,948 mm) long with the 16 in stroke and 427 in (10,846 mm) with the 18 in stroke, 136 in (3,455 mm) wide, and 103 in (2,617 mm) or 140 in (3,556 mm) high. For dust collection over that distance Onsrud suggests a floating duct system. The spindle is 18 hp (13.4 kW), 24,000 rpm, with 12 tools as standard.

Frequently Asked Questions
01
334 in (8,484 mm) in X by 61 in (1,550 mm) in Y, the same in the 16 in and 18 in blocks of the maker's table. It has 7 vacuum zones as standard.
02
The frame is 431 in (10,948 mm) by 136 in (3,455 mm) with the 16 in stroke and 427 in (10,846 mm) by 136 in (3,455 mm) with the 18 in stroke. Height is 103 in (2,617 mm) and 140 in (3,556 mm). Loading areas and guarding are extra.
03
Onsrud lists a floating duct dust collection system among the additions for the G-Series 5-Axis. On a machine with a 334 in (8,484 mm) table the gantry travels a long way, and the dust hose has to follow it without dragging.
