Addison Machine Engineering Is Founded

Walter and his two sons, Ronald and Gerald, partnered to form Addison Machine Engineering. As a general machine shop, Addison Machine produced parts for many industries while still focusing on tube mill tooling and regrind services out of their Addison, Illinois plant.

Addison's First Tube Mill

Ron Brunken designed Addison's first tube mill for their new tube-producing sister company formed by Gerald Brunken Sr.

Having worked his entire life as a supplier to the tube and pipe industry, Ron understood what producers wanted: solid and reliable mills. He started sketching out a mill that tube producers needed.

His goal: design and build the best mills in the business.
