How much does the SW BA W08-21 cost?
Price estimate
We do not have a price for the SW BA W08-21 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 BA W08-21 is a twin-spindle machining center for large parts, with linear drives and one work table. Each spindle has 800 mm (31.5 in) of X and 660 mm (26.0 in) of Z. Y is 1,025 mm (40.4 in) with HSK-A63 or HSK-A80 and 975 mm (38.4 in) with HSK-A100.
The spindle distance row is unusual. SW prints 799-851 mm, with 800 mm in brackets for the HSK-A63 and HSK-A80 spindles and 840 mm in brackets for HSK-A100. A range in that row points to spindles that can be set apart within limits, which fits the independent axes SW advertises on its other W machines. Ask SW exactly how the distance is adjusted and whether it can change within a program.
With a single table, the 4th axis swings Ø 1,650 x 1,830 mm. Two large parts side by side, each within 800 mm of X, turn together on one carrier. SW names aluminium engine blocks, gearbox housings and strut mountings among the parts for the series, and a video on the page presents this model and the BA W08-11 as large single-table machines.
Spindles are 35 kW and 80 Nm at up to 17,500 rpm on HSK-A63, or 42 kW and 200 Nm at up to 12,500 rpm on HSK-A80 and HSK-A100. Parts are changed with the spindles at rest, which is acceptable where cycles are long.

Frequently Asked Questions
01
SW's table gives 799-851 mm (800 mm) with HSK-A63 or HSK-A80 and 799-851 mm (840 mm) with HSK-A100. The table does not say more about the range, so confirm with SW how the distance is set.
02
The BA W08-21 has one work table, up to 1,025 mm (40.4 in) of Y and a Ø 1,650 x 1,830 mm interference circle. The BA W08-22 has two tables, 900 mm (35.4 in) of Y, a fixed 800 mm (31.5 in) spindle distance and a Ø 950 x 1,830 mm circle.
03
Per spindle: 35 kW and 80 Nm with a 1-17,500 rpm range on HSK-A63, or 42 kW and 200 Nm with a 1-12,500 rpm range on HSK-A80 or HSK-A100.
04
800 mm (31.5 in) in X and 660 mm (26.0 in) in Z. Y is 1,025 mm (40.4 in) with the HSK-A63 or HSK-A80 spindle, or 975 mm (38.4 in) with HSK-A100.
