Brown & Sharpe / Screw machine products

For the production of high tolerance precision parts, Edward Köehn Co., Inc. offers screw machining services for customers in a range of industries. Parts are fabricated on site at our state-of-the-art facility, utilizing Brown and Sharpe equipment featuring live tooling, single spindle, and high speed capabilities. This process is ideal for higher quantity, slightly open tolerances, and is cost effective. Material options include ferrous, non-ferrous, steel, stress proof, quenched, stainless steel, aluminum, brass, bronze, copper, and titanium as well as plastics including PVC, polypropylene, nylon, acrylic, PFE, UMHW, and torlon, among others.

Manufacturing operations include boring, knurling, reaming, and turning, as well as specialized methods such as boring and deep hole drilling. Our expert thread rolling, external thread cutting, internal thread cutting, and single point threading techniques are used to create all standard and custom threads. A host of value added secondary operations are performed as necessary including drilling, tapping, milling, and deburring. Customers are also invited to take advantage of our value added options including design services, heat treating, burnishing, grinding, packaging, and light assembly. Screw machined parts are manufactured in sizes up to 13" in length and up to 1.685" in diameter, maintaining tight tolerances to ±0.001". The highest quality levels are upheld throughout fabrication, with thorough in process and post production oversight including inspection, material certification, and outside processing with approved supplier list. For more details about our rapid and affordable screw machining production process or the other services available please see the table below or contact us directly.
