TRUSTED MACHINING
CAPABILITIES
YOU NEED HIGH-QUALITY MACHINED PARTS DELIVERED ON TIME, FROM PROTOTYPING TO
HIGH-VOLUME. THAT’S WHAT WE DO.
Founded in 1945, Cass Precision Machining serves you from a five-building campus—including over 125,000 square feet of production space—located in Brooklyn Center, Minnesota. We’re experts in Swiss Machining, CNC Machining, Screw Machining and Finish Grinding. Over the years 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 you with “complete parts” by adding coordinated services such as anodizing, plating, heat treating, shot peening, light assembly, warehousing, custom packaging and more—always ensuring we meet the quality specifications of your finished part.
We design and manufacture our tooling in-house, which shortens delivery lead times and aids in quick validation of DFM efforts, particularly on prototype orders. Our expanded warehouse and shipping / receiving areas support customized JIT programs on high-volume production runs, which at times, run in the millions.

SCREW MACHINING
At Cass Precision Machining, we utilize 60 automatic screw machines. Screw machines have evolved from their origins in Switzerland to excel at machining round, square, or hex bar stock in high volumes at world-class output rates. Our screw machine shop can process a wide variety of materials, including cold-rolled carbon steels, alloys, aluminum, brass, bronze, some series of stainless steels, tubing, and selected plastics. Screw machines can fully produce a wide range of custom build-to-print parts, including bolts, spacers, pins, bushing, nuts, fasteners, and many more with features ranging from simple to complex. Every day, our screw machining teams produce and ship thousands of parts.
Two of our five buildings at Cass Precision Machining house screw machine shops, including 43 New Britain automatic, multi-spindle screw machines, all equipped with bar feeders. The multi-spindle feature on these machines support high volume parts production and provide high part-per-hour output rates. The result is high-quality screw machine parts at globally competitive price points. Typical production releases start at 1000 pieces with production orders ranging as high as hundreds of thousands of parts. These multi-spindle screw machines can handle bar stock material ranging from .187 inch (4.765 mm) up to 3.5 inch (88.9 mm) diameters. From a part geometry perspective, the overall length of parts start at .030 inches (.762mm) and run up to 4.0 inches (101.6 mm). Although material selection will impact the tolerances that we can hold on this equipment, standard tolerances for these machines is +/- .005 inches (.127 mm). Depending on the material selected, +/- .002 inches (.050 mm) can be achieved.
Cass also operates 17 single-spindle Brown & Sharpe automatic screw machines. These machines feed single bars at a time, and while fully able to run similar parts to our multi-spindle equipment, they are geared for lower-volume orders and faster changeovers. Most of the screw machines in this area are equipped with Servo-Cam technology, which facilitates the automation of certain aspects of set-up and changeover work. This equipment can handle the full range of materials noted above and is our preferred processing area for tubing. Bar diameters range from .125 inches (3.175 mm) up to 2 inches (50.8 mm). When end work on one or both ends is exclusively required, Cass can provide part lengths as high as six feet. Standard tolerances on these machines are +/- .005 inches (.127 mm); however, depending on the material selected, +/- .002 inches (.050 mm) can be achieved.
- Superior Service
- Quality Assurance
- Shipping & Storage
Our customers tell us they are thrilled with our ability to ship on time – every time. Quick responses to quote requests are a priority for us. From prototype through high-volume production run orders, we make sure we acknowledge every order we receive so you know in advance what you can expect from our team. In addition, our DFM (Design for Manufacturability) resources are available to help you review and optimize the total costs of your parts. Changes happen, but you can be confident we will support your needs and minimize the hassles. We can make sure that changes in your part design or delivery requirements are quickly deployed into manufacturing so you don’t skip a beat. You can count on us to be there for you for the long haul. Consistent. Reliable. Trusted.
Cass has developed a baseline quality assurance system that guarantees we will ship high-quality parts – on every order. Everything we make passes several in-process checks and a final inspection, or it won’t go out the door. When your requirements dictate, we can customize our baseline system to your specifications, tailoring our quality-assurance system to fit your business needs. We are experienced with quality-assurance tools—SPC, PPAP Cpk, 1st Articles and more—to help you get exactly the results you require in your precision machined parts. Come visit us and check out our systems. We think you’ll like what you see.
To sustain our ability to ship on time – every time, we recently completed a 26,000 sq. ft. expansion to our warehousing, shipping and receiving areas. The added space dramatically improves material flow within our campus and improves efficiencies in our shipping and receiving functions. With the larger warehouse we are able to provide inventory release management programs, which improves the production flow of your lines while allowing us to run optimized quantities under blanket orders. Consistent. Reliable. Trusted.
