Price estimate
We do not have a price for the SW BF 25-22S 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 SW BF 25-22S is a twin-spindle machining center for long, slender parts. SW's page titles it the long and describes it as specialized for long components like extrusion profiles. The work space says the same: 2,500 mm (98.4 in) of X for each spindle against only 400 mm (15.7 in) of Y and 400 mm (15.7 in) of Z.
The spindles are 500 mm (19.7 in) apart, and the 4th axis has an interference circle of Ø 500 x 2,700 mm. Picture two extrusions clamped parallel along a rotary beam 2.7 metres long, each machined by its own spindle over its full length and turned to present every side.
SW lists side and cross members, subparts of battery housings, sills, crash profiles and guide rails as typical parts. On such profiles the work is holes, pockets and cut-outs spread along the length. The standard HSK-A63 spindle, with a 1-17,500 rpm range, 35 kW and 72 Nm, has ample capacity. An HSK-E50 spindle with a 1-40,000 rpm range, 18 kW and 11.5 Nm is marked optional.
Linear drives and independent Z axes are on the feature list. Independent Z matters on extrusions, which are never perfectly straight. Each spindle can follow its own profile in depth. Loading in parallel to machining time is also listed, and the model name ends in a 2 in the position SW uses for work tables.

Frequently Asked Questions
01
Long components. SW's feature list calls it specialized for long components like extrusion profiles, and names side and cross members, subparts of battery housings, sills, crash profiles and guide rails as workpieces.
02
2,500 mm (98.4 in) in X, 400 mm (15.7 in) in Y and 400 mm (15.7 in) in Z per spindle. The spindle distance is 500 mm (19.7 in) and the interference circle of the 4th axis is Ø 500 x 2,700 mm.
03
Two HSK-A63 spindles with a 1-17,500 rpm range, 35 kW and 72 Nm each. SW marks an HSK-E50 spindle as optional, with a 1-40,000 rpm range, 18 kW and 11.5 Nm.
04
Extruded profiles vary in straightness and twist along their length. With independent Z axes, which SW lists among the flexibility features, each spindle can be corrected to its own part. Two profiles can then be held to depth tolerances at once.
