Swiss Screw Machining: CAM & CNC

With many machines available, Severna Operations can meet your turn around times and design needs for most projects. Along with these machining services, we also provide CAM design services in-house.

We have a variety of materials for your precision plastics project, such as Teflon®, Fluoroloy H®, and Ultem®. Through swiss screw machining, we also offer a large range of dimensions for your project: from as small as .008” up to 3” in diameter, meeting tolerances as tight as ±.0005″.

After completing production of your components, we use various metrology equipment to fully inspect each part. Depending on the needs of the project, we also offer cryogenic and hand deburring.

Benefits of Swiss Screw Machining

Swiss screw machining can take projects that would usually require multiple hours and stops on a 5-axis machine, and machine them in 15 minutes with one operator. When we receive a design, we get to work determining the process for using the machine. Our machinists determine the best way to create the design and meet high tolerances based on the engineering requirements.

These machines allow us to produce a large volume of precision plastic parts quickly and efficiently, so we can meet the demands of any industry.
