Oil, Gas & Energy

We specialize in precision CNC milling and CNC turning services, providing custom CNC machining for oil, gas, and energy components that demand proven reliability, tight tolerances, and long-term performance under pressure. Through advanced technologies, expert programming, contract manufacturing efficiency, and end-to-end OEM support services, we deliver high-integrity parts for both traditional and renewable energy markets.

Precision CNC Machining for Oil, Gas & Energy Systems

We partner with OEMs and Tier 1 suppliers across the industrial gas and energy sectors to provide CNC machining for critical systems used in gas separation, compression, storage, and transport. From cryogenic components to tanker assemblies, our team combines advanced technology with decades of programming experience to produce precision parts that perform in the harshest conditions. 

Bring Complex Geometries to Life

Many components in oil, gas, and energy systems feature intricate channels, ports, and sealing surfaces that require extreme precision. Using advanced 3-, 4-, and 5-axis milling, we machine complex geometries in a single setup, reducing operations, improving part accuracy, and cutting lead times. 

Achieve Reliable Precision

Our CNC turning service and CNC milling capabilities deliver repeatable precision. By holding tolerances down to ±0.0003″, we help prevent leaks, reduce rework, and extend the life of key system components. Our commitment to accuracy ensures long-term dependability in mission-critical energy operations. 

Reduce Lead Times & Cost

Expert programming and efficient process planning help complete more features in a single setup, reducing handling between operations. This streamlined approach supports shorter lead times and greater cost efficiency while maintaining reliable precision and consistency.

Enhance Surface Quality and Reliability

Precise programming and stable machining setups help maintain surface consistency and dimensional accuracy. This attention to detail supports better sealing performance and long-term reliability in high-pressure oil and gas applications.

Improve Machinability of Tough Materials

 
Our programming expertise is especially valuable when machining stainless steels, superalloys, and tool steels used in oil and gas systems. By carefully controlling each operation, we maintain accuracy and repeatability across these challenging materials, ensuring reliable production of high-performance components.
