Thats how we got into broaching parts.Because it was a high-volume automotive application that required broaching about 2 million parts annually, Ty Miles needed to ex-tend its regular operating hours from 5 a.m. to 5 p.m. to 1 a.m. to 10 p.m., Mueller added. The company ran that program for about five years using two machines.On one machine, we were broaching four parts at a time, doing internal splines and other forms on an aluminum yoke part from the steer-ing column, he said. We also broached an ex-ternal slot on the clamp yoke.With that production broaching experience under its belt, the company took on additional automotive parts a few years later and contin-ues to broach parts with the machines it builds Ty Miles performs the majority of its production work using vertical broaching machines, with rotary broaching reserved for tasks like generating the twist on pistol barrels.A.
