SW Schwäbische Werkzeugmaschinen BAW08-22

This high-precision twin-spindle machining center of the SW series is designed for maximum productivity in high-volume manufacturing, particularly for the automotive and supplier industries. The machine features two symmetrically arranged motor spindles, a double NC swivel carrier, and two directly driven rotary tables, enabling simultaneous 5-axis machining and parallel processing.

Equipped with a Siemens 840D sl CNC control, minimum quantity lubrication, high-dynamic feed drives, and an 84-position tool magazine, the system guarantees highly dynamic, precise, and energy-efficient machining processes. Its compact design and pick-up capable tool concept ensure short chip-to-chip times and high machine availability.

This machine is ideal for demanding precision machining tasks such as housings, structural components, gearbox parts, and components made from aluminum, cast iron, and steel in large-scale production.
