How much does the Onsrud 216GW8 cost?
Price estimate
We do not have a price for the Onsrud 216GW8 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
Eighteen feet by eight, with up to 40 in (1,016 mm) of Z: that is the Onsrud 216GW8. The table is 216 in (5,487 mm) in X and 96 in (2,439 mm) in Y, and Onsrud lists the model in both its 28 in (711 mm) and 40 in blocks.
The eight-foot width is the useful part. It takes material that a five-foot table cannot, and on a tall-stroke machine that usually means large blocks and wide assemblies instead of sheet. The 217G covers the same length class at 61 in (1,550 mm) of Y, but it stops at 28 in of stroke and stands lower.
For either stroke the frame is 323 in (8,205 mm) long, 172 in (4,369 mm) wide and 167 in (4,242 mm) high. The length equals that of the 217G. The extra width and height are what the wide gantry and the taller column cost.
Onsrud lists 5 vacuum zones. The head is the standard one for the series, 18 hp (13.4 kW) and 24,000 rpm with a 12-tool capacity. Long tools cutting at the bottom of a deep part load the spindle and gantry hard, and the maker's description of one-piece steel columns, a helical rack and dual drives is the part of the specification that matters most for that kind of cut.
