What Is St. Paul, MN, Oil and Gas Precision Machining?
Oil and gas precision machining covers the production of high-spec components designed for the industry’s most punishing environments. These components are key to drilling, refining, and transport infrastructure—where breakdowns aren’t tolerated.
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.
Need CNC machining for demanding environments? Roberson Machine Company has you covered. From geometry to metallurgy to schedule, our process handles it all without sacrificing quality.

Types of Precision Machining We Use for St. Paul, MN, 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: Enables multi-surface machining, sharp angles, and deep-pocket features in one pass.
- CNC Turning: Handles rotational parts with tight tolerances and smooth surface finishes.
- Wire EDM: Great for cutting hardened metals and complex profiles that milling can’t handle.
Supporting Processes
- CAD/CAM Programming: Helps us validate toolpaths and detect issues before cutting—saving time and material.
- Robotics and Automation: Reduces cycle times and improves consistency across mid- to high-volume runs.
- In-Process and Final Inspection: Each part goes through in-process and final checks with CMMs and measurement tools to confirm spec compliance.
That’s how we support high-stakes energy projects—both in St. Paul, MN, and across the U.S.
Rapid Prototyping Capabilities
Rapid prototyping helps us deliver functional parts fast—especially useful for oilfield components that need quick design validation. By integrating CAD and CAM workflows, we can iterate designs, test functionality, and identify improvements before full-scale production begins.
To support production and logistics, we provide value-added services like labeling, sub-assembly, and packaging. Start a conversation with our team.
