CNC Turning Services

Over the past 85 years, Jessen has grown to become one of the world’s largest suppliers of precision CNC machined products. We have done this by committing to excellence throughout the company; a team –oriented approach to creating innovative manufacturing solutions and using only the most advanced equipment and technologies. Our Okuma CNC lathes are equipped with sub spindles for back working operations, multi axis turrets, live tooling, (for drilling, milling and turning operations) and bar feeder’s capable of up to 3 1/8”stock and chucking capacity up to 14”. Utilizing the live tools, Jessen can hold critical geometric tolerances by eliminating re-chucking of the parts and completing them in only one competitive operation. We provide CNC turning of stainless steel, copper, aluminum, carbon and alloy steels, brass, bronze, plastic and many other exotic materials.

We also offer ID and OD Hard Turning on parts starting at 45 Rc and higher, providing tolerances and micro finishes historically associated with grinding. Common hard turned materials include tool, bearing and case-hardened steels, as well as all other metallurgical challenging materials. Hard turning eliminates operations and can provide substantial cost savings.
