How much does the SW BA W04-22 cost?
Price estimate
We do not have a price for the SW BA W04-22 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 W04-22 is the linear-drive counterpart to the BA 4: two spindles 400 mm (15.7 in) apart, two work tables, and feed axes that SW describes as offering the highest dynamics due to linear drive technology. Travel per spindle is 400 mm (15.7 in) in X, 500 mm (19.7 in) in Y and 425 mm (16.7 in) in Z.
Where the BA 422 offers five spindle packages, this model has one. Each HSK-A63 spindle runs through 1-17,500 rpm with 35 kW and 80 Nm. That is a light-metal specification. 80 Nm handles drilling, tapping and milling in aluminium comfortably, and the speed range suits the small carbide tools such parts use.
SW's part list for the series reflects that: ABS valve housings, turbochargers, pivot bearings, inverter housings and steering knuckles. Several of these need a great many holes and threads. The feature list advertises the largest integrated tool magazine, with 232 tools, which on a two-spindle machine has to hold everything in duplicate.
The 4th axis clears Ø 425 x 1,030 mm. Fixtures are therefore long and slim, typically a bridge that carries several parts per spindle. When cycle time is made of many short moves between holes, the acceleration of the linear axes is the reason to choose this model.

Strengths & Limitations
Strengths
- Linear drive technology on a twin-spindle machine with two work tables
- 17,500 rpm, 35 kW and 80 Nm per HSK-A63 spindle
- SW lists the largest integrated tool magazine, with 232 tools
- 400 x 500 x 425 mm of travel per spindle at a 400 mm (15.7 in) spindle distance
- Ø 425 x 1,030 mm interference circle gives a long clamping bridge
Limitations
- One spindle package only: no HSK-A80 and no high-torque version
- 80 Nm per spindle limits heavy cuts in cast iron and steel
- The interference circle is Ø 425 mm across, so fixtures cannot be tall
- Rapid traverse and acceleration figures are not in SW's table

Frequently Asked Questions
01
The W0 in the name stands for linear drive in SW's nomenclature. Travel and spindle distance match, but the BA W04-22 has a single spindle package of 35 kW and 80 Nm at up to 17,500 rpm, where the BA 422 offers five packages up to 42 kW and 300 Nm.
02
Two HSK-A63 spindles, each with a speed range of 1-17,500 rpm, 35 kW and 80 Nm. SW's table shows no alternative interface or rating for this model.
03
The 4th-axis interference circle is Ø 425 x 1,030 mm, and each spindle reaches 400 mm (15.7 in) in X, 500 mm (19.7 in) in Y and 425 mm (16.7 in) in Z. That shape favours a long clamping bridge with parts arranged along the rotary axis.
04
SW's feature list for the BA W04 series states the largest integrated tool magazine, with 232 tools. The table does not say how the places are divided between the two spindles, so check the usable number per spindle for your tool sizes.
