In 2020 Cass Precision Machining launched C-RPM (Cass Rapid Proto Machining), a new service that supports Cass customers with build-to-print rapid prototyping parts. The response from customers has been exceptional and Cass has now produced over 30 prototype parts.

The goal of C-RPM is to supply customers with machining expertise and design for manufacturing engineering consulting to deliver the finished part they desire.

The expert C-RPM team at Cass offers quick-turn responses in each prototyping phase:

• Feasibility Review
• Small-quantity fitment builds
• Refining of prototype
• Concept/pre-production demonstration runs
• Full production runs

The goal of the C-RPM team is to supply customers with a “complete” part based on the customer’s print that can then be easily turned into production parts. Cass provides C-RPM material consulting, machining expertise, and coordinated services to deliver the finished parts customers are looking for. Your C-RPM team is ready to provide rapid responses to your prototype parts needs with part size ranges from up to eight inches in diameter to 26 inches in overall length.

“Opening our C-RPM service adds another key step in Cass’s evolution of providing a broader range of solutions for our customers,” said Jim Garvin, Cass’s President. “This new business unit adds another facet to supporting clients’ supply chain needs over the full life cycle of their parts.”

The C-RPM cell can handle a wide range of materials, including alloys, carbon, stainless steel, titanium, aluminum, brass, bronze, machinable plastics, and more. CNC milling and complex turning capability are the cornerstones of the C-RPM unit.

Finishing services include anodizing, heat treating, plating, shot peening, custom packaging, light assembly, and more.

“At Cass, we’re proud of our long tradition of listening to our customers and taking the appropriate actions as a reliable partner that our clients can trust,” said Garvin. “Cass-Rapid Proto Machining lines up with the growing needs of clients and enables us to support more creative design solutions.”

Cass Precision Machining has made a concerted effort to ramp up our C-RPM initiatives by investing in two machines that help us turn out quality parts in a timely fashion.

The Tsugami M08SY Turning Center with Y-axis allows Cass to perform highly complex machining, such as turning, drilling, boring, cross-drilling, and CNC milling. The main and sub-spindle are equipped with integral built-in spindle motors, which minimize vibration and provide superior accel/decel for heavy-duty cutting and fine finishing.

The Doosan 5700 Mill is part of a series that offers larger cutting space by 6%, bigger table sizes by 14%, and heavier loads by 25% while maintaining the same overall footprint as the previous generation. The new DNM series features direct-coupled, thru-coolant type spindles as standard, providing 8,000 rpm (15/11 kW) and 12,000 rpm (18.5/11 kW). Vibration and noise are greatly reduced during high-speed operations, and thermal displacement is also improved. The direct-drive spindles also contribute to faster accel/decel rates, and tool change times have also been optimized to reduce non-cutting time.

Send our C-RPM team your prints, or we can discuss your design ideas online. Our prototype team can handle a wide range of materials as mentioned above—challenge us with your material requirements!

C-RPM Machining—CNC Milling and Live Tool Lathe machines are the cornerstones of the cell.

The finishing services Cass customers have come to expect lead to the rapid delivery of prototype parts that boost your production line.
