Deep Hole Drilling for Railway Applications: Axles, Wheelsets, and Couplers
Railway components – axles, wheelsets, couplers, and brake components – are heavy, long, and have tight quality requirements. I have been working on these parts for over a decade and they present a unique set of challenges compared to smaller, higher-volume deep hole drilling jobs. In my experience, the railway industry uses deep hole drilling for three main purposes: through-boring axles for weight reduction, drilling oil holes in couplers and knuckles, and boring wheelset bores for axle fit. ...
