History of Cass Precision Machining

Lester E. Cass started Cass Precision Machining in 1945 in downtown Minneapolis with a belief that customer service should always be a top priority. We started as a small, single-machine shop and have grown into a six-building campus in Brooklyn Center, Minnesota.

Since the very beginning, we’ve delivered high-quality machined parts on time and at a fair price. Our emphasis on customer service has allowed us to grow into a global machining supplier, with customers across the USA and parts shipped worldwide.

To serve such a wide variety of clients, we’ve invested in the latest technology to stay nimble in how we provide services to our ever-changing customer needs. We believe it’s our ability to “go the extra mile” for our customers that has led us to span so many miles across the globe to provide our services.

Cass Precision Machining has continued to grow over the years, adding more machines and more operators to meet the demands of our customers. We are now a manufacturing company that offers rapid prototyping, Swiss machining, CNC machining, screw machining, and precision grinding. We also coordinate outside services including anodizing, heat treating, plating, shot peening, and more.
