- Precision at Every Stage
Thermo-Mechanical Machining of Refractory Alloys
Advanced strategies control thermal loads and surface integrity to reduce microcracks and maintain grain structure in heat-affected zones.
Submicron Machining Accuracy
Submicron precision is achieved using 5-axis CNC systems with kinematic calibration, volumetric compensation, and dual-probe alignment, maintaining tolerances under 0.0015 mm across complex contours and rotational axes.
Thermal Distortion Control
Thermal distortion is minimized by applying predictive expansion models, adaptive toolpath corrections, and isothermal machining strategies, ensuring dimensional integrity in large or heat-sensitive precision components.
Engineered Surface Finishes
Surface finishes are optimized using synchronized multi-stage polishing, real-time tool wear feedback, and interferometric inspection, achieving consistent Ra values for sealing, wear resistance, or biocompatibility-critical surfaces.
- Step-by-Step Machining Approach
Our CNC Machining Process
Every component is machined through a controlled sequence of thermal, mechanical, and dimensional operations tailored to the material and application.






Advanced algorithms optimize tool paths, minimizing tool wear, reducing cycle times, and improving surface finishes. This involves strategically planning the sequence of movements and cuts to enhance efficiency.
Modern CNC machines often utilize 5-axis or even 6-axis capabilities, allowing for complex geometries and intricate shapes. This reduces the need to reposition the part, ensuring higher accuracy and a more refined finish.
CNC machines may integrate adaptive cutting strategies, where cutting conditions (speed, feed, depth of cut) adjust dynamically based on real-time sensor feedback or cutting force monitoring. This helps prevent tool breakage and ensures optimal material removal rates.
Specialized techniques like high-speed machining enable faster spindle speeds and advanced feed rates. This increases material removal rates while maintaining fine tolerances and reducing thermal distortion.
Some CNC setups incorporate in-process measuring systems (like laser scanners or probe-based systems) to check the part’s dimensions as it’s being machined. These systems can send real-time data back to the machine, allowing for automatic adjustments during production.
CNC machines with automated tool changers enhance efficiency by switching tools automatically without operator intervention. This allows for uninterrupted multi-operation machining without downtime, improving productivity in complex jobs with several cutting tools.

Frigate uses wear-resistant alloys and controlled machining parameters to extend part life. Advanced simulation is used before production to check how the component will behave in high-pressure, corrosive environments. Each machined part is tested for dimensional stability under thermal cycling. This ensures long-term reliability even in offshore or deep well operations.
Frigate uses 5-axis CNC machines to create intricate oilfield connectors with tight threading tolerances. CAM software generates optimized toolpaths for internal and external threads, reducing tool deflection. Surface finish is enhanced using controlled cutting speeds and post-machining treatments. This allows consistent sealing performance in high-pressure joints.
Toolpath optimization minimizes machine vibration and thermal distortion during long tool engagements. Frigate uses real-time monitoring systems to dynamically adjust speeds and feeds. This reduces wear on carbide tools when cutting tough materials like Inconel or duplex stainless steel. The result is improved feature accuracy in long borehole parts.
Frigate uses dual-spindle lathes and in-process probing to control concentricity within microns. Each part is inspected using CMMs for true position and roundness deviation. Precision workholding and thermal compensation are used to avoid distortion. This ensures functional alignment between mating surfaces during fluid regulation.
Frigate uses horizontal machining centers with rotary tables to machine large housings in a single setup. This eliminates tolerance stack-up from multiple repositions. Stress-relieving heat treatments are applied before and after machining to reduce deformation. Final verification includes ultrasonic and dye-penetrant testing of all machined interfaces.
