Consistent Quality & Precision
We maintain strict dimensional tolerances down to ±0.005 mm. Using advanced inspection tools (including CMM and projectors) and certified RoHS/REACH-compliant raw materials, we ensure every brass component meets your exact technical specifications.
No Minimum Order Quantity (MOQ)
We have no strict MOQ limits. Whether you need a single prototype for design validation or low-to-medium volume production, we welcome and support orders of all sizes to fit your budget.
Reliable Delivery & Clear Timelines
Our standard prototypes or samples are typically delivered within 1 week (complex parts may require additional time). For production orders, our standard lead time is 30 business days. We always provide a detailed delivery schedule before signing the contract so you can plan with confidence.
One-Stop Turnkey Service
We simplify your supply chain by handling everything under one roof. From raw material extrusion and precision CNC milling/turning to secondary surface treatments (such as plating and passivation) and professional packaging, we deliver ready-to-use parts directly to your facility.

How We Master Brass & Pure Copper CNC Machining
Copper alloys vary significantly in physical properties; machining parameters, tooling, and coolant strategies must be adapted per grade to maintain dimensional accuracy and surface finish.
Brass CNC Machining (grades C36000/HPb59‑1, C26000/H70, C28000/H62)
Material traits
- C36000 (leaded): excellent machinability.
- C26000/C28000 (lead‑free): high ductility, produces long, stringy chips that can wrap around spindles or scratch surfaces.
Process measures
- For C36000: high‑speed multi‑axis CNC turning with optimized feed rates.
- For ductile lead‑free grades: use inserts with aggressive chip‑breaker geometry to break chips into short segments.
- Post‑machining deburring (vibratory tumbling + microscopic inspection) for cross‑holes and internal threads to eliminate micro‑burrs.
Pure Copper CNC Machining (grades C11000, C10100)
Material traits
- Excellent conductivity but extremely soft and ductile; prone to built‑up edge (BUE) on tools and tearing, affecting tolerances and surface quality.
Process measures
- Use ultra‑fine micro‑grain carbide tools with polished rake faces and DLC coatings to reduce friction and BUE.
- Apply high‑pressure flood coolant directly to the cutting zone for rapid heat dissipation and immediate chip evacuation.
- Design rigid workholding fixtures and use light, fast cutting passes to minimize deflection and maintain dimensional control.
FAQ
Q: What is your quote process?
A: Send us an inquiry with your CAD drawings (STP/IGS/X_T/PDF). Our engineers will conduct a process evaluation within 24 hours and provide you with a detailed quote including unit price, lead time, and technical recommendations.
Q: What differentiates your Brass Precision Turned Components from other manufacturers?
A: Our core strength is precision. You'll achieve dimensional stability and surface finish that far exceeds industry standards.
Q: Besides brass, do you machine other materials?
A: Yes. In addition to our specialized CNC Machining Copper Services, we also specialize in precision machining of a variety of materials, including stainless steel, aluminum alloys, titanium alloys, and engineered plastics.
Q: What surface finishes and plating options do you offer for custom brass components?
A: Depending on your mechanical and aesthetic requirements, we offer a complete range of in-house and certified-partner surface finishing treatments:As-Machined / Degreased,Passivation,Electroplating and Sandblasting & Bead Blasting
Q: Can your engineering team assist with Design for Manufacturability (DFM) reviews to reduce costs?
A: Yes. We don't just cut metal; we collaborate with your team. When you submit your 2D/3D CAD drawings (STEP, IGES, or PDF), our mechanical engineers review the design. If we identify features that might unnecessarily drive up machining costs (such as excessively deep blind holes, overly tight non-critical tolerances, or sharp internal corners), we will propose practical DFM alternatives to optimize your budget without compromising part functionality.
