- Our CNC Process
End-to-End Metal Machining Workflow
We deploy stabilized fixturing, thermal offset correction, and high-speed adaptive tool engagement for tight-tolerance parts used in defense assemblies and field-ready firearms.






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.

Having Doubts? Our FAQ
Check all our Frequently Asked Questions in CNC Machining
Frigate uses live-axis compensation and reinforced tailstock support to stabilize long-barrel receivers during CNC turning. A custom mandrel alignment system ensures bore concentricity throughout the length. Cutting speeds are synchronized to the natural harmonic frequency of the barrel stock to reduce whip and internal chatter. Each receiver undergoes optical bore inspection and concentricity validation against a zero-runout master. This guarantees consistent fitment and accuracy under repeated firing loads.
Frigate uses synchronized coolant pulsing and segmented tool paths to limit thermal buildup in suppressor baffle cuts. Material pre-conditioning reduces residual stress before final contouring. Titanium and Inconel parts are finish-milled using low-rpm, high-torque passes to prevent hot-spot distortion. Each suppressor core is laser-profiled post-machining to confirm axial symmetry and wall thickness consistency. This maintains performance under sustained thermal cycling in field use.
Yes, Frigate uses vacuum workholding combined with multi-axis probe verification to maintain tight flatness and angular tolerances in scope rail mounts. Rail slots are cut using climb milling to prevent surface lift. A 3D CMM validation checks every critical axis for perpendicularity and rail alignment. Final mounts are sample-tested on calibrated alignment jigs. This process ensures repeatable optical zeroing across batches.
Frigate machines alloy bolts using synchronized threading cycles and flank relief control to avoid stress concentration. Tool inserts with controlled rake angles reduce heat input during thread passes. Real-time torque monitoring flags deviation from preset force windows, which helps prevent material hardening or burr formation. Final threads are gauged using pitch micrometers and verified against go/no-go ring gauges. This maintains function reliability under repeated cycling.
Frigate applies synchronized twin-pallet setups to alternate load-unload cycles during frame machining. High-speed tool changers and path-optimized CAM programs shorten non-cutting time. Each tool path uses acceleration smoothing to prevent corner overshoot. Laser referencing resets fixture zero points without manual touch-off. Final parts pass digital profile scanning to confirm cut accuracy. This method balances speed with dimensional fidelity.
