Cass Precision Machining is an award-winning precision machining company that began operations in 1945 as a single-machine shop in downtown Minneapolis. Since then, we’ve grown our campus into six buildings comprising over 125,000 square feet of production space to excel as your full-service machining partner.

We’re experts in rapid prototyping, Swiss machining, CNC machining, screw machining, and precision grinding. Over the decades, we’ve worked with many types of materials including alloy, carbon and stainless steels, aluminums, brasses, bronzes, tubing, and a wide variety of machinable plastics.

We provide our customers with complete parts by adding coordinated outside services such as anodizing, plating, heat treating, shot peening, and more to always ensure we meet the quality specifications of the finished part.

We design and manufacture our tooling in-house, which shortens delivery lead times and aids in quick validation of Design for Manufacturing (DFM) efforts, particularly on prototype orders. Our expanded warehouse and shipping/receiving areas support customized Just-in-Time (JIT) programs on high-volume production runs, which at times, run in the millions. We take pride in being a precision machining company that’s Consistent. Reliable. Trusted.
