Machining

Tim Espy, plant manager at V W Broaching Service Inc., Chicago, provides the play-by-play as an internal spline is created on a 24" dia. ball valve for a water utility. The broaching shop uses a Colonial horizontal broaching machine to produce the spline in the stainless steel valve in just a few seconds.
