A new line going in at factory #36. I did not go in here more than a handful of times so I do not recognize the area. Rollert 1960 |
I ran a broach in the head department from 1996-2004. I heard that the broach was made by the Cincinatti Broach company in the 1950s. According to what I heard the broach was made to machine v-8 heads and when Buick bought the V-6 tooling back from in the 1970s they were retrofitted.
ReplyDeleteThe broach uses a long series of carbide cutters to shave off metal. This process is quicker that milling but cruder. We used to have a .004 limit on flatness variation. The broach could run one hundred and fifty parts in a good hour. Chris Balog
