Brass Machining
High-speed precision brass turned and milled parts — fittings, nuts, bushings, connectors and contacts.
Overview
Brass machines faster than almost any metal, with excellent dimensional stability, corrosion resistance and conductivity — ideal for high-volume precision fittings, connectors, valves and electrical parts.
Our brass CNC machining uses free-cutting C3600/C3604 for fast, economical brass machined parts and brass turned parts, with lead-free ECO brass and naval brass for drinking water and marine use.
Capabilities
High-speed turning
Complex fittings, nuts, bushings and contacts at high spindle feeds.
Milling & drilling
Brass manifolds, valve bodies and multi-port connectors.
Threads & knurling
Precision threads, tapered fittings and decorative knurling.
Electrical / conductive
Pins, contacts, terminals and RF/battery components.
Lead-free options
Eco brass and naval brass for potable water and marine use.
Plating & finishing
Nickel, tin, chrome plating or natural clear-coated brass.

Frequently asked questions
Why is brass economical for CNC?
Free-cutting brass allows high feeds and speeds, short cycles and long tool life, lowering part cost even for complex shapes.
Can you provide lead-free brass?
Yes. We machine ECO/lead-free and naval brass for drinking-water, plumbing and marine applications.
Can brass parts be plated?
Yes. We offer nickel, tin and chrome plating, or natural brass with an anti-tarnish clear coat.
What is the typical tolerance?
We hold ±0.01 mm on critical features; standard turned tolerances are IT6–IT7.
