Below is a list of Broaching Job Shops manufacturers from Rochester Hills, Michigan. Broaching job shops are facilities that specialize in the metal removal service known as broaching, which creates cut outs, holes and profiles in metal performs called workpieces. Most broached products are produced in these facilities, when metal workpieces are broached internally or externally in high runs and large volumes. The broaching process is cost effective, easy and efficient because it is done with automated or CNC operated machinery that is either horizontal or vertical in orientation.
