How much does the Onsrud 291X cost?
Price estimate
We do not have a price for the Onsrud 291X 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 291X is the X-Series model at 418 in (10,618 mm) of machine length, and the shortest with two material stop zones. It is a 5-axis extrusion machine with an 18 hp (13.4 kW), 24,000 rpm spindle and a 28 in (711 mm) Z-stroke.
Compared with the 165X it gains the second stop zone and a clamp range of 10-12. Two zones allow one profile to be loaded while another is machined, the main reason to choose this length over the shortest one even for parts that would fit the smaller machine.
The frame is a steel structure on a heavy-duty steel base, which Onsrud says cuts down the vibration caused by machining extrusions. Width is 131 in (3,328 mm) and height 140 in (3,556 mm).
The section the machine accepts is 21 x 14 in (533 x 356 mm). Standard tooling is 12 positions. The 33 hp (24.6 kW) spindle is worth pricing if the profile mix includes thicker walls, though the maker's own advice for heavy work is its EX line. A 400mm saw blade is optional, and the control is FANUC or Onsrud's touchscreen interface.
