Precision Brass CNC Turned Parts | High-Tolerance Machined Components for Connectivity & Fluid Control
Mastering the Art of Brass Precision
Optimizing Conductivity, Machinability, and Compliance for Tier-1 Industries
In high-speed connectivity and fluid control systems, a brass component is only as good as its micro-precision. At Senlan Precision, we specialize in High-Tolerance Brass CNC Machining, transforming premium alloys into reliable engineering solutions.
By balancing high-speed Swiss-turning with advanced surface treatment, we deliver components that meet the strict RoHS/REACH standards of the Western medical, electronic, and automotive markets.
Overcoming the Quality Barriers in Brass Machining
-
Guaranteed Material Compliance (RoHS & REACH)
-
The Issue: Uncertified alloys can lead to legal liabilities and product recalls due to excessive lead content.
-
Our Solution: We offer 100% material traceability. From C36000 Free-Cutting Brass to Lead-Free Eco-Brass, every order is accompanied by a certified Material Test Report (MTR) ensuring your products are ready for global distribution.
-
Zero-Burr Micro-Machining for Sensitive Systems
-
The Issue: Microscopic burrs in internal threads and cross-holes can compromise the integrity of fluid valves and electrical connectors.
-
Our Solution: Utilizing high-frequency ultrasonic cleaning and specialized chemical deburring, we ensure all internal and external features are "Medical-Grade" clean. Our inspection team performs 100% verification under high-magnification microscopy.
-
Exceptional Straightness & Concentricity for Thin-wall Designs
-
The Issue: Thermal expansion and clamping stress often cause thin-walled brass parts to lose their geometric precision.
-
Our Solution: We deploy Swiss-type CNC Turning Centers (Citizen/Tsugami), which provide superior support for long, slender, or thin-walled parts. This technology allows us to maintain concentricity and roundness within ±0.005mm, ensuring a flawless fit in automated assembly lines.

FAQ – Proactive Solutions for Strategic Buyers
Q: How do you handle the high thermal expansion of brass during tight-tolerance runs?
A: Our production facility is climate-controlled, and we use high-flow cooling systems to maintain a constant temperature at the tool interface, preventing dimensional drift.
Q: Can you provide customized knurling patterns for plastic over-molding?
A: Yes. We offer diamond, straight, and helical knurling with controlled depth to ensure maximum pull-out force in your over-molding applications.
Q: Is your facility equipped for Lead-Free Brass machining?
A: Absolutely. We have dedicated production lines for lead-free alloys to prevent cross-contamination with standard leaded brass.
