SW North America Inc.’s BA 322 is a compact, twin-spindle HMC targeted for four- or five-axis machining of small to medium-sized steel, cast iron and light metal workpieces. Typical examples include brake calipers, hydraulic valves and turbocharger components, including compressor wheels. The double swivel table design allows workpieces to be loaded/unloaded in cycle. The BA 322 name represents the 300-mm distance between the two spindles and two tables. It is the smallest frame size of the company’s heavy-duty machining centers.

BA 322 is equipped with two spindles, a specially developed twin swivel trunnion, and twin or quadruple five-axis modules to suit the actual machining requirement.

To ensure precise machining and a rigid framework, the BA 322 incorporates a monobloc machine bed. This stiff cube carries the three-axis unit equipped with a maximum four spindles. The simultaneously machining of four spindles provides great efficiency and maximizes workpiece throughput. This spindle arrangement provides optimum chip flow.

The machining center was designed to be highly productive. In lieu of synthetics, SW relies on lost-wax-cast collets in high-alloyed steel, controlled by a cylinder and monitored to confirm the tool is correctly locked.
