What Is St. Louis, MO, Oil and Gas Precision Machining?

Oil and gas precision machining involves the production of mission-critical components built to perform in harsh, unforgiving environments. These parts are used in drilling, refining, and transportation systems where reliability isn’t optional.

Oil and gas components often face:

• High operating pressures
• Corrosive fluids and gases
• Extreme heat and temperature swings
• Constant vibration and mechanical shock
• Particulate exposure

Roberson Machine Company provides CNC machining services specifically suited to these demands. Our equipment, programming, and inspection workflows are built to handle complex geometries, tough materials, and aggressive production schedules—without compromising quality.

Roberson Machine Company delivers CNC machining capabilities built for the rigors of oil and gas work. Every project runs through high-end machines and detailed inspection workflows designed for precision and repeatability.

Types of Precision Machining We Use for St. Louis, MO, Manufacturers

When the specs are signed off, we begin production with CNC tools dialed in for performance and consistency. Whether it’s a massive pump housing or a complex sealing feature, we’ve got it covered.

Machining Capabilities

• 3-, 4-, and 5-Axis CNC Milling: Lets us cut complex forms and precision features without changing setups.
• CNC Turning: Produces concentric, cylindrical parts like bushings, shafts, and couplings with speed and precision.
• Wire EDM: Used for parts that require tight internal radii, clean edges, and no mechanical stress.

Supporting Processes

• CAD/CAM Programming: Lets us visualize and perfect toolpaths digitally, cutting down on mistakes and setup time.
• Robotics and Automation: Ideal for reducing manual input and keeping part quality steady at scale.
• In-Process and Final Inspection: Critical features are inspected during and after machining using calibrated CMMs and precise measuring tools.

That’s how we support high-stakes energy projects—both in St. Louis, MO, and across the U.S.

Rapid Prototyping Capabilities

Our rapid prototyping services make it easy to move from concept to tested component—ideal for oil and gas parts that need validation in the field. Our combined CAD and CAM workflow helps identify design improvements early—before production even starts.

We offer value-added machining support that includes marking, light assembly, and packing. Reach out to plan your project.
