How much does the Onsrud 375EX cost?
Price estimate
We do not have a price for the Onsrud 375EX 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 375EX is the mid-length EX-Series extrusion machining center: 531 in (13,488 mm) of machine, 12 clamps, 2 material stop zones. The 5-axis head is driven by a 33 hp (24.6 kW) spindle at 24,000 rpm and has 40 in (1,016 mm) of Z-stroke.
From this size up the clamp count is fixed at 12 instead of the 10-12 range of the 265EX. More clamps over more length means long, flexible profiles can be supported closely, and the servo clamps can still be moved by the program when a cut needs the space.
A machine over forty feet long needs a straight, stable floor and a plan for getting stock in and parts out. Width, 147 in (3,734 mm), and height, 189 in (4,801 mm), are the same as on the shorter models, so the length is the only thing that grows.
The work area cross-section is 21 x 14 in (533 x 356 mm). Onsrud says the high-speed spindle and frame give fast tool changes, acceleration and chip-to-chip time; it publishes no figures for them. A 24-tool changer and a 75 hp (55.9 kW), 18,000 rpm spindle are the listed upgrades, and the control is FANUC or Onsrud's touchscreen interface.
