AEM Tool and Machining is a third generation owned and operated machine shop serving our customers for over 70 years. We are located in Sun Prairie WI and serve multiple industries throughout the U.S. Our specialization is in CNC machining, low volume production, custom machined parts, prototyping and tool and die machining.

Russel Webber founded the family business as Acme Sales and Service shortly after returning home from serving in the U.S. Army during World War II. He started out repairing electric motors and radios. In the 1960s he began focusing on re-winding electric motors and doing machine shop work for a local business. Through the years the shop evolved to focus on custom machining.

His two sons Robert and Richard joined him and formed Acme Electric and Machine L.L.C. in the early 1990s. In the early 2000s they began doing business as AEM Tool & Machining. In January 2020 Richard's son, Paul, took over business operations. Throughout all these years we have always been committed to providing our customers with quality and integrity and strive to machine finished parts that exceed expectations.
