Severna's plastic CNC turning services provide custom-machined parts to meet our customer's precise specifications. Our capabilities include contour, form, taper, and straight turning, as well as external and internal threading. With full 5-axis and live tooling, our turning machines can also perform processes such as parting/cutting, facing, internal forming, drilling, and boring. Our turning machines can handle parts up to 8" in diameter and 12" in length, and work to turning tolerances as tight as ±.0005". If needed, we can design and manufacture custom turning tools and accessories. Severna is familiar with a wide variety of materials from ABS to Vespel®, which allows us to serve a range of industries. With an extensive materials inventory, we can offer shorter production and delivery schedules. Additional services include cryogenic and hand deburring.

Severna fully inspects all parts to ensure the highest quality. Severna is an ISO 9001:2008-certified company. To learn more about Severna's plastic CNC turning services, please contact us or see the table below.
