The advantage of multi-spindle machining is simultaneous machining of several workpieces thus considerably reducing costs. It is also possible to assign several workpieces to one spindle. In SW clamping fixtures, designed and manufactured in our plant.

• Caliper brackets
• Engine and gearbox housings

Since its launch the SW BA series is setting standards in the field of multi-spindle, heavy machining.  Due to the excellent accessibility of the loading area from the front and from the top the machine can be loaded and unloaded manually or via an automated system - again in parallel with the machining process. For these machines SW is offering the multiple cnc controls

Efficiency.

There are many ways to machine steel and cast iron workpieces. But there are only a few allowing to reach an optimum result in view of the given situation. The SW BA class offers a machining center which has set standards in its class with regard to effi1ciency and performance and which will continue to do so. The BA 400 and BA 600 centers available with 2 or 4 spindles, with 4 and 5 axes which can be loaded in parallel with the machining process provide for the appropriate concept for your machining process.
