How much does the Onsrud 527X cost?
Price estimate
We do not have a price for the Onsrud 527X 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 527X is the longest X-Series model with a complete set of published dimensions: 649 in (16,485 mm) long, 131 in (3,328 mm) wide and 140 in (3,556 mm) high. It machines extrusions on five axes with an 18 hp (13.4 kW), 24,000 rpm spindle.
Onsrud's table also shows a longer 653X, but its machine sizes are printed with a letter after each figure and cannot be taken as firm. For a buyer who needs certainty on the building, the 527X is the largest X-Series machine that can be planned from the published numbers.
The working figures are those of the series: a 21 x 14 in (533 x 356 mm) work area, 28 in (711 mm) of Z-stroke, 12 tools. There are 12 clamps and 2 material stop zones.
On a bed this long with a light spindle, productivity comes from keeping the spindle busy. Running two shorter profiles alternately, one in each stop zone, does that. So does the 33 hp (24.6 kW) spindle upgrade when the sections allow higher removal rates. The optional 400mm saw blade and the clamping system, which on this series is an automated option, decide how much of the work is finished without a second operation.
