High-Quality Custom CNC Brass Machining Part

Brass is one of the most machinable copper alloys—but producing clean threads, controlled cross-holes, and tarnish-resistant finishes requires dedicated process control. FlexiTurn delivers precision CNC machining for custom C36000 brass components, including bearing housings, manifold blocks, sensor flanges, and threaded connectors, all manufactured directly from your 2D and 3D CAD files.

C36000's lead content improves machinability, but chip management remains critical. Optimized cutter geometry, cutting parameters, and coolant delivery ensure controlled chip formation, preventing tool entanglement and surface scratching.

Brass is the preferred material for threaded fittings and valve bodies. Rigid tapping and thread milling produce accurate, burr-controlled internal and external threads that pass thread plug/ring gauge verification on every critical feature.

Valve bodies and bearing housings demand high-precision bores and tight concentricity. Multi-axis machining centers complete boring, face milling, and cross-drilling in a single setup, ensuring tight positional accuracy across all features.

Brass oxidizes naturally over time. We provide specialized anti-tarnish treatments, chromate conversion coatings, electroless nickel plating, bright polishing, and ultrasonic cleaning to preserve surface appearance and meet application-specific corrosion requirements.

Why Choose FlexiTurn for Custom Brass Machining?

Dedicated Free-Cutting Brass Expertise

Brass machining is not generic CNC work. Our process engineers optimize cutting parameters, tool selection, and chip evacuation specifically for C36000, C26000, and C46400 alloys, ensuring clean threads and consistent surface finishes.

Beyond brass and copper alloys, FlexiTurn operates complete CNC production lines for aluminum, stainless steel, alloy steel, engineering plastics, and composites—supporting integrated multi-material assemblies under one roof.

Every CAD file receives a complimentary Design for Manufacturability evaluation within 24 hours—assessing wall thickness, thread depth ratios, tool accessibility, and tolerance callouts to optimize unit cost and lead time.

Brass parts live or die by thread quality and dimensional accuracy. Our inspection protocol includes thread plug/ring gauge verification, 3D CMM dimensional inspection, optical profile testing, and material certification (MTR) with every shipment.

Functional brass prototypes delivered in 3 to 5 business days with zero minimum order quantity (MOQ) requirements, scaling smoothly into serial production.
