Our Clients
- Process Capability for Precision Die Milling
Multi-Axis CNC Machining for Oilfield Components
Dimensional tolerances and sealing profiles are maintained using controlled toolpaths in high-pressure, high-temperature, and corrosive environments.
Flatness Control Under Load
Surface deviations over ±0.003 mm cause seal distortion. Frigate ensures flatness via synchronized axis milling and FEA-driven toolpaths, preserving joint integrity under bolt preload in high-pressure systems.
Grain Stability in Hardened Alloys
Local thermal softening during machining disrupts alloy performance. Frigate applies low-engagement strategies with directed cooling to preserve grain boundaries in critical areas exposed to hydrogen and cyclic stress.
Concentricity for Rotating Parts
Sub-10 µm concentricity prevents imbalance in rotating assemblies. Frigate maintains alignment using C-axis interpolation and multi-point probing, ensuring axial precision in high-speed, high-cycle components.
- Machining Workflows
Our CNC Milling Process
Tight component tolerances and fine feature depths are achieved through high-speed, thermally stable CNC milling in cleanroom-compatible workflows.
Engineers design the part using CAD (Computer-Aided Design) software. The design includes all dimensions and specifications.
The CAD design is converted into CNC code, often using CAM (Computer-Aided Manufacturing) software. This code tells the milling machine how to move and cut the material.
Operators prepare the CNC milling machine by securing the material (workpiece) and installing the appropriate cutting tools.
The CNC machine reads the code and starts milling. The cutting tool rotates and moves along multiple axes to remove material from the workpiece and shape it into the desired part.
The machine monitors the cutting operations throughout the process. Operators may make adjustments to ensure precision and quality.
After milling, the part may undergo additional processes like deburring or polishing to achieve the final specifications.
The finished part is thoroughly inspected to meet all design requirements and tolerances.

Frigate uses FEM-based toolpath simulation and real-time spindle load monitoring to predict and mitigate deflection. High-rigidity cutters and optimized holder overhang are chosen based on cavity depth and material modulus. Custom chip evacuation strategies are deployed to avoid thermal stress buildup. This maintains tight dimensional conformance across complex geometries.
Frigate aligns CMM pre-checks with rotary axis calibration data to ensure positional accuracy before milling. Integrated probing systems validate concentricity after each indexed pass. Multi-axis synchronization eliminates eccentricity during contouring cycles. This results in perfectly centered bores across all critical flow sections.
Thermal expansion coefficients are modeled during CAM stage for toolpath compensation. Frigate uses flood coolant with active spindle temperature control to reduce thermal drift. Tool dwell times are minimized in heat-sensitive regions to avoid warping. In-process laser scanning confirms dimensional stability post-milling.
Frigate applies sequential face milling with controlled cutter compensation and anti-vibration mounts. Each finishing pass is calibrated for axial runout using dial indicator readings. The surface is measured with a white-light interferometer to confirm flatness below 1 micron. Final surface prep includes lapping if flatness deviation exceeds tolerance.
The feed per tooth is dynamically controlled based on workpiece hardness mapping. Frigate uses high-performance carbide tools with edge prep geometry optimized for duplex grades. Adaptive control systems adjust spindle RPM to maintain optimal chip thickness. This prevents tool failure and improves surface edge quality.
