CNC Turning & Milling of Stainless Steel Seal Block for a Throttle Valve

Seal Block

For over 49 years, Westboro Machine has offered precision machining services such as milling and turning to produce everything from the simplest parts to specialty manufacturing of highly intricate and complex components. We also excel in providing our services for various turbine applications. Our expert staff has worked with brass, bronze, plastics, copper, aluminum, steel, and much more.

One of our largest customers asked us to manufacture a 2-9/16” long seal block for a throttle valve that would be used in their latest steam turbine design. Material used was 416T stainless steel and manufactured on our Okuma Cadet Lathe and HAAS VF4 4-axis mill. Completed parts underwent extensive quality control before undergoing nitride heat treatment. The valves were also precisely machined according to the latest NPT pipe thread and heat treatment standards.

Impressed by our expertise in precision machining, our customer was pleased with the final component and continues to work with us on additional projects. Since 1966, we’ve been a full service machine shop that prides itself on producing high-quality, made-to-order parts for customers across a variety of industries. Our team can also provide subcontracted services such as heat treating, grinding, anodizing, plating, coating, and painting services.
