How much does the Onsrud F146S cost?
Price estimate
We do not have a price for the Onsrud F146S 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
At 144 in (3,658 mm) by 60 in (1,524 mm), the Onsrud F146S has the longest table in the S-Series 5-Axis range. It is a fixed-bridge 5-axis router with a 28 in (711 mm) Z-stroke and an 18 hp (13.4 kW), 24,000 rpm spindle as standard.
Three vacuum zones divide the table, against 2 on the F122S and 1 on the F62S. For 5-axis work that helps when two or three fixtures share the bed, each on its own zone, so several short parts can be trimmed in one cycle.
The machine is big in every direction: 310 in (7,874 mm) long, 163 in (4,141 mm) wide and 153 in (3,887 mm) high. Onsrud attributes the rigidity of the S-Series to its steel frame and to a bridge that spans the short dimension of the table. On a twelve-foot table that choice matters, since the alternative would be a bridge twice as long.
A second tool changer, a 33 hp (24.6 kW) spindle and Z-strokes of 16 in (406 mm), 40 in (1,016 mm) or 52 in (1,321 mm) are the listed upgrades. Onsrud also names continuous C rotation, robotics integration, material-handling systems and custom vacuum zones for this series.

3 as standard. Custom vacuum zones are among the options Onsrud names for the S-Series 5-Axis, which is useful when fixtures do not match the standard layout.
03
18 hp (13.4 kW) as standard and 33 hp (24.6 kW) as the upgrade, at 24,000 rpm according to the series page. Verify the rating at order, because the maker's lineup overview quotes other values for its 5-axis routers.
04
The tables match: both are 144 in (3,658 mm) by 60 in (1,524 mm) with 3 vacuum zones. The F146S is a 5-axis machine with a 28 in (711 mm) standard Z-stroke; the 146S is 3-axis with 11 in (279 mm).
