SW BA W02-21

The SW BA W02-21 is a compact linear-motor machining center with two spindles and a single work table. That last point is what separates it from its sibling: in SW's naming scheme the digits after the dash are the number of spindles and the number of work tables, and W0 stands for linear drive. The spindles sit 250 mm (9.8 in) apart and each one covers 200 mm (7.9 in) in X, 350 mm (13.8 in) in Y and 300 mm (11.8 in) in Z.

With one table instead of two, the 4th axis has more room to swing. SW gives an interference circle of Ø 500 x 630 mm for this model, against Ø 425 x 630 mm on the BA W02-22. The larger circle helps with taller fixtures or parts that have to rotate around a wide clamping bridge.

Spindle choice follows the rest of the BA W02 series. An HSK-A40 spindle runs to 25,000 rpm with 18 kW and 17 Nm, and an HSK-E40 spindle runs to 36,000 rpm with 14 kW and 7 Nm. SW's series feature list also mentions a spindle with 40,000 rpm, a figure the table for this model does not show, so confirm it with SW if that speed matters.

SW names knee joints, impellers and scroll parts as typical workpieces. Those are small, contour-heavy parts where axis acceleration matters more than spindle torque, and that is the case SW makes for linear drives in this size.
