Frigate utilizes dual-spindle lathes with synchronized rotation control to ensure axial and radial alignment during the turning process. In-process probing verifies concentricity tolerances down to 0.005 mm. The machines compensate for tool deflection in real-time using feedback from load monitoring systems. This ensures flawless sealing performance in API-class valve bodies and stems under extreme pressure.
Frigate uses multi-pass fine turning with controlled feed rates and CBN tooling for sulfide stress cracking resistance. Post-turning, surfaces undergo non-directional burnishing to reduce residual tensile stress. The process is validated through profilometry and micro-hardness checks. This ensures compatibility with sour gas environments per material performance specifications.
Frigate uses live tooling with synchronized tailstock pressure to manage deflection on shafts exceeding L/D ratios of 10:1. The machines employ coolant-through tooling with thermal compensation modules. Laser inspection after rough and finish passes helps detect taper and drift. This approach guarantees stability in components like drill string subs and mandrels.
Frigate deploys custom-designed soft jaws and programmable chucking pressure systems to avoid part distortion. Vacuum workholding is used in some cases to distribute stress evenly. Finite element analysis is done beforehand to simulate clamping-induced stress zones. This results in dimensional integrity for critical components like sensor housings and telemetry enclosures.
Frigate machines premium threads using synchronized C-axis control and calibrated threading cycles. Real-time torque monitoring ensures consistent chip load across each pass. Threads are then verified using certified gauges and surface replication methods. This approach supports compatibility with torque-turn specifications and ensures leak-proof performance in downhole applications.
