How much does the SW BA one8 cost?
Price estimate
We do not have a price for the SW BA one8 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 one8 is the larger of SW's two single-spindle precision machines. Its work space measures 800 mm (31.5 in) in X, 1,000 mm (39.4 in) in Y and 650 mm (25.6 in) in Z, and the axes are driven by linear motors.
Y is the long axis. That is rare, and it tells you about the parts: SW names engine blocks, cylinder heads and strut mountings. An engine block stood on end in a rotary fixture needs height more than width, and 1,000 mm of Y gives the spindle access along its full length.
Three interfaces are listed. HSK-A63 comes with a 1-17,500 rpm range, 35 kW and 80 Nm. HSK-A80 and HSK-A100 both come with 1-12,500 rpm, 42 kW and 200 Nm. The choice between the last two is about tool stiffness and tool weight, since the motor rating is the same.
The 4th-axis interference circle is Ø 965 x 1,030 mm. SW's feature list repeats the claim made for the smaller model, for highest precision machining requirements, and lists loading and unloading in parallel to machining time. Flexible automation solutions, a line on most SW pages, is missing from this one. Ask how the machine is to be loaded if it has to sit in an automated line.

Frequently Asked Questions
01
800 mm (31.5 in) in X, 1,000 mm (39.4 in) in Y and 650 mm (25.6 in) in Z. The interference circle of the 4th axis is Ø 965 x 1,030 mm, which bounds the fixture and part together.
02
HSK-A63, HSK-A80 and HSK-A100. The HSK-A63 spindle has a 1-17,500 rpm range with 35 kW and 80 Nm. The HSK-A80 and HSK-A100 spindles have a 1-12,500 rpm range with 42 kW and 200 Nm.
03
SW names engine blocks, cylinder heads and strut mountings, and lists automotive, e-mobility, hydrogen and fuel cells, and aerospace as industries. The feature list positions the machine for highest precision machining requirements.
04
Envelope and purpose. The BA W08-11 has 1,500 mm (59.1 in) of X for wide parts. The BA one8 has 800 mm (31.5 in) of X and 1,000 mm (39.4 in) of Y and is the one SW describes as built for the highest precision requirements.
