Angular heads by ROMAI for Compensating Bores in Crankcases
Compensating bores or pulsation holes, as they are called at BMW in Steyr, are bores running laterally in the crankshaft bearings of 6-cylinder gasoline engines. In order to implement these, additional front-end holes would have to be drilled, which afterwards would have to be closed with screw plugs. A specially developed angular head by ROMAI, adapted to the tight space available within the crankcase, as well as to the high cutting forces, and the limitations of the automatical tool changer (atc), makes this effort redundant.
