CNC Swiss Screw Machining of a Monel Stem

At Ostec Industries, we provide rapid turnaround of precision machined parts for specialized client requirements. We fabricated the valve stem pictured here for a customer in the oil & gas industry, and the high quality of our workmanship ensured that it would provide a long service life when exposed to the conditions of a caustic environment.

We fabricated this part from Monel R405, the best choice for Swiss screw machining components that would be exposed to salt, seawater, high temperatures, or acidic conditions. Featuring dimensions of Ø 0.4375” and 3.51” in length, we precision machined the component to within Ø 0.3120/0.3105 tolerances, then deburred and ground it to a highly smooth 12 RMS surface finish. Quality assurance by means of dimensional, visual, and gage inspections validated part integrity.

Manufactured in quantities of 15,000 a month, we shipped the parts according to our customer’s just-in-time delivery requirements. For more information about this project or our precision CNC Swiss turning services, contact us today.
