Custom CNC Brass Faucet Components

Precision machining services for residential, commercial, and industrial plumbing assemblies. Optimized for high tolerance, leak-free performance, and superior surface finish.

Quick Answer: CNC Brass Components

CNC-machined brass faucet components are precision-milled parts used in fluid control systems. They replace traditional casting methods to achieve stricter tolerances and better thread accuracy.

  • Typical Parts: Valve bodies, spouts, threaded connectors, knobs, adapters
  • Common Alloys: C360, C377, CW617N, Lead-Free Brass
  • Tolerance: ±0.02 mm standard
  • Surface Treatments: Polishing, Chrome/Nickel Plating, PVD Coating

Complex Brass Valve Body

Complex Brass Valve Body

Customer: European Faucet Manufacturer

Material: CW617N (Lead-Free Compliant)

Challenge: Internal flow channels featured complex angles requiring multi-axis synchronization to prevent tool collision and ensure wall thickness.

Solution: Implemented 5-axis CNC machining with custom fixturing to complete the part in two operations.

Result: Achieved better sealing performance, reduced leakage rates to near zero, and improved customer assembly efficiency by 15%.

High-Precision Thread Adapter

High-Precision Thread Adapter

Customer: North American Plumbing Supplier

Material: C360 Free-Cutting Brass

Challenge: Required extreme thread accuracy (ISO 228-1) to prevent cross-threading during field installation.

Solution: Utilized Swiss-type CNC turning with rigid tapping and in-process thread measurement.

Result: Achieved 99.8% first-pass yield, eliminating customer rejection claims.

What Affects the Cost of CNC Brass Parts?

Understanding cost drivers helps optimize your design for manufacturing (DFM). We provide transparent quotations based on the following critical factors.

Material Grade (e.g., Lead-free is costlier) High Impact

Order Quantity (Economies of scale) High Impact

Thread Complexity Medium Impact

Surface Finish (Ra0.8 vs Ra0.4) Medium Impact

Inspection & Testing (CMM, Pressure testing) Medium Impact

Frequently Asked Questions

What brass grades do you machine?

We regularly process C360, C377, CW617N, and various lead-free brass alloys compliant with North American and European drinking water standards.

What tolerances can you achieve?

Our standard machining tolerance is ±0.02 mm. For critical sealing surfaces or threads, we can consistently hold ±0.01 mm.

Can you manufacture from STEP files?

Yes, we accept STEP, IGES, DWG, and PDF formats. Our engineers will review the model and provide a DFM report before quoting.

What is your typical lead time?

For standard custom brass parts, lead time is 7-12 days for prototypes and 3-4 weeks for mass production, depending on surface treatment requirements.
