With our expertise in CNC machining, Key Gas Components has attained a leadership position in the manufacture of high-quality gas train components and specialty machined components. We operate a well-equipped machining department that incorporates state-of-the-art turning and milling centers and is staffed by production specialists that work as a team to ensure the quality and integrity of your machined components. Our years of experience serving gas equipment manufacturers give us the depth of knowledge to provide creative and cost-conscious solutions for supplying custom products that satisfy the strictest quality and safety criteria.

Our CNC machining capabilities enable us to produce parts with the utmost level of precision. Along with metals like alloy steel and aluminum, we machine parts from copper, bronze, nickel, super alloys, and many others. We can uphold dimensional tolerances as close as ¬Ī.001‚ÄĚ on milled parts that measure as large as 118.0‚ÄĚ in length x 12.0‚ÄĚ in width x 16.0‚ÄĚ in height. Within a maximum diameter turning capacity of 1.625‚ÄĚ bar-fed, and 4‚ÄĚ as a chucker, we can achieve ¬Ī.0005‚ÄĚ tolerances on concentricity. Our technical competency enables us to develop highly specialized processes for creating complex features and thread patterns that conform to your specifications and meet or exceed industry standards.

As an experienced manufacturing and engineering company, we have staff available to help you with product development and design to ensure your machined components meet your functional and quality requirements. We are capable of handling small orders as well as those that involve mass production with just-in-time delivery. By embracing lean manufacturing strategies, we keep costs low and prices competitive.
