How much does the Onsrud F122S cost?
Price estimate
We do not have a price for the Onsrud F122S 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 F122S is the ten-foot 5-axis S-Series router, and the only one for which Onsrud prints dimensions at two Z-strokes. The table is 120 in (3,048 mm) by 60 in (1,524 mm), the standard Z-stroke is 28 in (711 mm), and the spindle is 18 hp (13.4 kW) at 24,000 rpm.
Height is where the two versions differ. With the 28 in stroke the machine stands 143 in (3,633 mm) high; with a 40 in (1,016 mm) stroke it is 162 in (4,115 mm). Length, 260 in (6,604 mm), and width, 153 in (3,887 mm), are identical. A buyer choosing the taller Z should check ceiling height and crane hook height first.
What goes on a table like this? Boat parts, aircraft interior panels, long thermoformed skins, stair parts, and anything else that needs five-sided machining over a ten-foot length. The single table moves lengthwise under the bridge and can be reached from three sides.
There are 2 vacuum zones. The tool changer carries 12 tools, with a second changer optional, and a 33 hp (24.6 kW) spindle is available. Onsrud lists 16 in (406 mm) and 52 in (1,321 mm) strokes too, though the dimension table covers only 28 in and 40 in for this model.
