Custom Brass CNC Machining

Custom brass CNC machining is our specialized metal processing service for global industrial buyers focusing on brass conductive, corrosion-resistant and easy-machining characteristics. Our factory is equipped with 3/4/5-axis CNC milling machines, CNC turning centers and Swiss precision lathes. As an ISO 9001:2015 certified brass machining manufacturer, we produce brass prototypes, small-batch custom fittings and mass production hardware with ultra-tight tolerances, mirror-smooth surface and consistent batch performance.

Different from traditional metal processing, our automated CNC system converts your CAD, STEP, IGS and STL 3D files into finished brass workpieces. We are good at miniature thin-wall brass parts, threaded valve cores and complex conductive terminals that are hard to process via ordinary cutting. We provide one-stop brass CNC machining solutions including DFM design optimization, raw material cutting, precision turning & milling, custom surface finishing and full quality testing for all customized brass parts.

Core Advantages of Our Brass CNC Machining

• Ultra-Stable Precision Machining: Standard tolerance ±0.02mm, ultra-precision tolerance up to ±0.005mm, fully meet electronics, plumbing and instrumentation high-precision standards.

• Miniature & Complex Part Machining: Multi-axis equipment supports tiny thin-wall brass structures, deep thread fittings and irregular conductive connectors without deformation.

• Complete Brass Grade Supply: Process H59, H62, H65, HPb59 lead brass, C36000 free-cutting brass, all raw materials attached official MTR material reports.

• Excellent Batch Consistency: Unified CAM programming and automatic clamping reduce manual errors, ensure identical dimension and surface gloss for mass brass parts.

• One-Stop Integrated Service: Free DFM drawing review, prototype trial, polishing, plating and full inspection, simplify your supply chain and cut procurement cost.

• Flexible MOQ & Fast Lead Time: Zero minimum order limit, accept 1pc sample and bulk orders of over 100,000pcs. Prototypes finished within 24–48 hours, batch orders delivered on schedule.

Brass CNC Machining Technical Specifications

Standard Production Workflow

All production links adopt standardized control to guarantee high conductivity, anti-tarnish performance and precise size of finished brass components.

Process Step Description

1. Drawing Review & DFM Analysis: Engineers check drawings, verify thread tolerance and thin-wall processing feasibility, provide free structural optimization suggestions to avoid machining defects.

2. Material Selection & Blanking: Match qualified brass rods/tubes per your requirements, complete incoming material testing and cut raw materials into standard blanks.

3. CAM Programming & Simulation: Programmers generate G-code based on 3D models and run virtual simulation to prevent tool collision and dimensional deviation.

4. Precision Brass CNC Machining: Low-friction special cutting tools and high-rigidity CNC machines finish turning, milling and composite processing to reduce brass burrs and deformation.

5. Deburring & Polishing Prep: Remove tiny burrs, clean sharp edges and metal debris to lay a foundation for high-gloss surface treatment.

6. Custom Surface Plating & Finishing: Carry out tin plating, nickel plating, gold plating, mirror polishing and passivation to improve conductivity, anti-tarnish and appearance.

7. Comprehensive Quality Inspection: Adopt CMM, roughness tester and conductivity testing equipment for full inspection, issue official quality certification documents.

8. Anti-Tarnish Packaging & Global Delivery: Use anti-oxidation oil film + shockproof foam packaging, re-inspect before shipment, support sea, air and express delivery worldwide.

FAQ

Can you customize brass parts according to my 2D drawings or 3D models?

Yes. We support customization based on CAD/STEP/IGS files, physical samples or design sketches, with free drawing technical audit and DFM optimization advice.

What brass grades can you process?

We process H59/H62/H65 common brass, HPb59 lead free-cutting brass and C36000 international standard brass, and can source special brass alloys on demand.

Do you offer electroplating and mirror polishing for brass parts?

We provide full surface treatment services including tin plating, nickel plating, gold plating, mirror polishing and anti-tarnish passivation.

How long is your production lead time?

Prototypes take 1–3 working days; small batches 5–7 days; mass production 7–12 days. Rush orders are acceptable.

Is there any minimum order quantity?

No MOQ limit. We accept single prototype and large-volume mass production orders.
