Custom Brass Precision Turned Parts Manufacturer

What Are Brass Precision Turned Parts?

Brass precision turned parts are custom-machined components produced on CNC turning centers to achieve high dimensional accuracy, consistent thread quality, and excellent surface finishes. They are commonly used in:

Plumbing
Automotive
Medical Devices
Electronics
Pneumatic Systems
Instrumentation
Item Capability
Material C360 / C377 / CW614N / CW617N
Tolerance ±0.01 mm
Surface Finish Ra0.8
MOQ Prototype & Mass Production



Why Choose CNC Turned Brass Components?

CNC turning offers unparalleled precision for brass fabrication. The material’s excellent machinability reduces tool wear and allows for high-speed production cycles. This process ensures tight tolerances, complex geometry execution, and superior surface finishes, reducing the need for secondary operations. The result is a reliable, high-performance component tailored for demanding industrial environments.

Brass Material Selection Guide

Grade Standard Best For
C360 ASTM B16 High-speed Machining
C377 ASTM B124 Forged Plumbing Components
CW614N EN12164 European Plumbing
CW617N EN12165 Valve Bodies
Lead-free Brass NSF/Drinking Water Food & Medical
Which Brass Material Should You Choose?

For general high-speed turning, C360 is the industry standard due to its free-machining properties. For European markets, CW614N and CW617N ensure compliance with regional plumbing directives. If your application involves potable water or medical equipment, lead-free brass is mandatory to meet strict health regulations.
