How much does the SW BA 222 & BA 222i cost?
Price estimate
We do not have a price for the SW BA 222 & BA 222i 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 222 & BA 222i is the smallest twin-spindle machining center in SW's range: two spindles set 200 mm (7.9 in) apart, each working in a space of 200 mm (7.9 in) in X, 350 mm (13.8 in) in Y and 300 mm (11.8 in) in Z. SW lists both names in one column of its BA 2 table, so the figures here apply to both. In SW's naming scheme the final 2 is the number of work tables and the i stands for integrated automation.
Two spindle packages are offered. The HSK-A40 spindle runs to 25,000 rpm with 18 kW and 17 Nm per spindle. The HSK-E40 spindle reaches 36,000 rpm with 14 kW and 7 Nm. Neither is a roughing spindle. With torque this low the machine is aimed at small cutters and light chip loads, which matches the workpieces SW names for the series: bone plates, pump housings and watch cases.
Both spindles cut at once, so every cycle finishes two identical parts and the fixture pitch has to follow the 200 mm spindle distance. The 4th axis clears an interference circle of Ø 425 x 630 mm, which is the real limit on fixture size. SW's feature list describes loading and unloading in parallel to machining time, a monoblock design and the option of an integrated loading module.
Buyers should settle the spindle choice early, because taper, speed and torque change together. They should also ask SW for the magazine capacity and the control, which the BA 2 table does not give.

Strengths & Limitations
Strengths
- Two spindles 200 mm (7.9 in) apart finish two parts per cycle in a work space of 200 x 350 x 300 mm per spindle
- Choice of a 25,000 rpm HSK-A40 spindle with 18 kW and 17 Nm or a 36,000 rpm HSK-E40 spindle
- Loading and unloading in parallel to machining time, per SW's feature list for the BA 2 series
- An integrated loading module is possible, and the BA 222i name marks the version with integrated automation
- SW describes the BA 2 as its highest productivity in minimum space
Limitations
- Torque is 17 Nm per spindle at most, and 7 Nm with the HSK-E40 spindle, so heavy roughing is out of reach
- X travel of 200 mm (7.9 in) per spindle and a Ø 425 x 630 mm interference circle keep parts and fixtures small
- The machine pays off only when parts run in identical pairs, with fixtures built to the 200 mm spindle distance
- SW's table gives no tool magazine capacity, rapid traverse or machine weight for this model

Frequently Asked Questions
01
SW prints both in one column of the BA 2 table, so the spindle and work space figures are the same: two spindles 200 mm (7.9 in) apart and 200 x 350 x 300 mm of travel per spindle. In SW's naming scheme the letter i stands for integrated automation, and the BA 2 feature list says an integrated loading module is possible.
02
Two. The HSK-A40 spindle covers 1-25,000 rpm with 18 kW and 17 Nm per spindle. The HSK-E40 spindle covers 1-36,000 rpm with 14 kW and 7 Nm per spindle. The faster spindle gives up more than half the torque, so it suits finishing with very small tools rather than general milling.
03
Each spindle has 200 mm (7.9 in) of X, 350 mm (13.8 in) of Y and 300 mm (11.8 in) of Z, and the spindles sit 200 mm apart. SW gives the interference circle of the 4th axis as Ø 425 x 630 mm. Part and fixture together must turn inside that circle, so check the swing of the fixture before the part itself.
04
SW's feature list for the BA 2 series names loading and unloading in parallel to machining time, and the final 2 in the model name is the number of work tables in SW's naming scheme. One table is in the cut while the other is at the loading side, so the spindles do not wait for the operator or the loader.
