Tight-tolerance machining for flat sealing faces and aligned bearing bores.
We machine gear case covers to ±0.001″ with controlled flatness and true bore alignment to prevent leaks and premature bearing failure. Production-ready processes deliver repeatable accuracy across batches with fast, predictable quoting.
Precision CNC Machining for Gear Case Covers
Gear case covers require flat sealing surfaces, accurate bearing bores, and consistent mounting geometry to ensure gearbox reliability and service life. We machine billet covers that hold tolerance across multiple faces and interfaces.
