How much does the SW BA W04-42 cost?
Price estimate
We do not have a price for the SW BA W04-42 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 W04-42 runs four spindles on linear drives. The spindle distance is 200 mm (7.9 in), each spindle has 200 mm (7.9 in) of X, and Y and Z are 500 mm (19.7 in) and 425 mm (16.7 in).
One detail in SW's table deserves attention. The four-spindle model keeps the full spindle rating of the two-spindle BA W04-22: 35 kW and 80 Nm per HSK-A63 spindle, with a speed range of 1-17,500 rpm. Many four-spindle machines step down to a smaller spindle to fit the pitch. Here nothing is given up per spindle except X travel.
The machine suits parts that are small, numerous and full of holes. SW names ABS valve housings first in its list for the series, and that part is the textbook case: a compact aluminium block with dozens of bores and threads. Four blocks per cycle, with the next four loaded on the second table during the cut, is how the output adds up.
Tool supply needs planning. Each operation takes four tools, and the 232-tool magazine SW lists for the series is shared by all four spindles. Fixtures turn inside Ø 425 x 1,030 mm. SW states 50% less energy used per part for its multi-spindle machines against single-spindle ones.

Strengths & Limitations
Strengths
- Four HSK-A63 spindles with the full 35 kW and 80 Nm each, the same rating as the BA W04-22
- 1-17,500 rpm speed range and linear drive technology
- Four parts per cycle at a 200 mm (7.9 in) pitch, with two work tables
- 232-tool integrated magazine on SW's feature list
- SW states 50% less energy used per part than single-spindle machining
Limitations
- 200 mm (7.9 in) of X per spindle: parts must be narrow
- Four spindles draw on one 232-tool magazine, so tools per operation are limited
- Interference circle of Ø 425 x 1,030 mm restricts fixture height
- No heavier spindle option in SW's table

Frequently Asked Questions
01
Spindle count and pitch. The BA W04-42 has four spindles 200 mm (7.9 in) apart with 200 mm of X each. The BA W04-22 has two spindles 400 mm (15.7 in) apart with 400 mm of X each. Spindle rating, Y, Z and the interference circle are the same in SW's table.
02
35 kW and 80 Nm per spindle, on an HSK-A63 interface with a speed range of 1-17,500 rpm. The machine has four such spindles.
03
Parts that fit a 200 mm (7.9 in) pitch and a work space of 200 mm in X, 500 mm (19.7 in) in Y and 425 mm (16.7 in) in Z per spindle. SW names ABS valve housings, turbochargers, pivot bearings, inverter housings and steering knuckles for the series; the smaller of these are the ones for four spindles.
04
Yes, by SW's naming scheme: the digits after the dash are the number of spindles and the number of work tables. The series feature list names loading and unloading in parallel to machining time, which is what the second table is for.
