Mid-range horizontal machining center

The BA 322 is a compact, twin-spindle horizontal machining center targeted for 4- or 5-axis machining of small- to medium-sized workpieces. The double swivel table design allows workpieces to be loaded/unloaded in cycle. It is the smallest frame size of SW North America’s heavy-duty machining centers.

The machine is equipped with two spindles, a specially developed twin swivel trunnion, and twin or quadruple 5-axis modules to suit machining requirements. For precise machining and a rigid framework, the BA 322 incorporates a SW monobloc machine bed. This stiff cube carries the 3-axis unit equipped with a maximum four spindles. Simultaneous machining of four spindles provides great efficiency and maximizes workpiece throughput. This spindle arrangement provides optimum chip flow.

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. Three magazine sizes, with up to 128 tools per machine, can be chosen. Tools are changed using the pick-up system. The un-tensioned chain of the magazine reaches speeds of up to 80mpm and runs in a link rail. Retightening is not necessary.

A hydraulic pack is required because SW not only offers the clamping fixtures with its components, but provides the elements necessary to control them. Each of the two workholding units on the twin swivel trunnion of the BA 322 are controlled by up to eight hydraulic pipes and an additional five pneumatic ones, all featuring rotary distributors.
