Importantly, the machine features a second, live tool workstation enabling up to 40,000 rpm milling to complement the 90-position automatic toolchanger that serves the 11 kW, 6,000 rpm main HSK-40 spindle. This additional station effectively doubles productivity by enabling up to five driven tools to work on the rear side of one part while the main tool spindle works on another component.
In one instance – the production of a stainless steel workpiece from 14 mm bar – the cycle time on a modern machining centre was 389 seconds. On the Bumotec S181, it took just 254 seconds to complete the part – a 38% productivity increase. The machine can handle bar of 32 mm diameter and, being of modular design, can be equipped with a range of options.
