Chevalier QP2560-L

The Chevalier QP2560-L is the largest QP vertical machining center, with 60.0 in (1,525 mm) of X travel and a 65.0 in x 25.0 in (1,650 x 635 mm) table rated for 3,300 lb (1,500 kg). The load figure sets it apart from the rest of the series: the next size down, the QP2440-L, carries 1,320 lb (600 kg).

Y and Z are both 25.0 in (635 mm). With the spindle nose reaching 29.9 in (760 mm) above the table, there is room for tall weldments, stacked fixtures or a large rotary table with a tailstock. Spindle center to column is 27.0 in (685 mm).

Size costs some speed. Rapid traverse is 1,181/1,181/944 ipm (30/30/24 m/min), a step below the smaller QP models in X and Y. The spindle is unchanged: #40 Big Plus taper, 2.8 in (70 mm) diameter, belt drive at 100 to 10,000 rpm or direct drive at 120 to 12,000 rpm. On a table that takes a ton and a half, a 40-taper spindle is the limiting factor for heavy roughing, so this is a machine for large parts with light to moderate cuts, not for hogging big steel blocks.

The tool changer is the 24+1 arm type at 2 sec tool-to-tool, with tools to 11.8 in (300 mm) long. Net weight is 18,700 lb (8,500 kg). The maker's floor space row for this model does not agree between its inch and metric columns and is omitted here. Chevalier lists linear ways on all axes and high pressure coolant across the series, under a Fanuc 0i-M control.
