CNC Brass Machining Process

As a leading CNC Machining service provider, EMAR specializes in precision brass components manufacturing. This article will explore the technical nuances of brass machining to help procurement managers and engineers make informed decisions.

Understanding CNC Brass Machining

CNC brass machining refers to the computer-controlled subtractive manufacturing process for creating brass parts with tight tolerances (typically ±.005mm). Brass alloys like C36000 (free-cutting brass) are preferred for their excellent machinability rating of 100% (compared to steel's 60%).

Key Process Stages

1. Material Selection: We use certified brass rods/billets with Cu content 60-63% and Zn 35-40% for optimal machinability and corrosion resistance.
2. CNC Programming: Our engineers develop toolpaths considering brass's softness (HB80-100) to prevent material adhesion.
3. Machining Operations: Combining turning (surface speeds 150-300m/min) and milling (feed rates .05-.15mm/tooth) for complex geometries.
4. Quality Control: CMM inspection with 3μm repeatability ensures dimensional accuracy.
