Custom Precision Brass CNC Machining Parts

FlexiTurn single-setup CNC-turns free-machining brass flanged threaded bushings — stepped flange shoulder, precision-turned OD, internal female thread — for wear-resistant bushings, threaded inserts and fluid connection components.

FlexiTurn specifies C36000 (UNS C36000) brass for chip control, self-lubricating bearing properties and consistent gold finish. FlexiTurn controls the three performance-critical metrics: thread-to-OD concentricity, flange face runout and thread accuracy.  FlexiTurn eliminates these with single-setup turning and sharp geometry-optimized tooling, delivering repeatable concentricity and consistent thread quality from prototype through production.

Machining Process & Capabilities

FlexiTurn runs all core brass turning in-house. Tooling geometry, spindle speed and feed are locked to free-machining brass for controlled chip evacuation and thread finish.

• Single-Setup CNC Turning: Outer diameter, flange shoulder, internal bore and internal thread are turned from solid brass bar in one chucking with a unified datum, eliminating re-chucking error and controlling thread-to-OD concentricity. Rough and finish passes are separated with sharp carbide tooling for controlled surface finish.
• Threading: Internal threads are cut or formed on the CNC lathe to ISO 6H standard. Thread class tolerance verified with go/no-go gages at first article and in-process sampling.
• Deburring: Thread exits and flange edges are deburred to remove cutting burrs without rounding functional bearing surfaces.
• Material Sourcing: FlexiTurn stocks C36000 free-machining brass bar. C54400 phosphor bronze for wear-critical bushings, C26000 cartridge brass and other copper alloys are available on request.
