What Are Brass Milled Components?

Brass milled components are precision parts manufactured using Vertical Machining Centers (VMC) or CNC milling machines where rotating cutting tools remove material from a solid Brass workpiece to achieve complex shapes, profiles, and tight dimensional tolerances.

Unlike conventional turning operations, milling allows multi-axis machining, enabling the production of complex features such as:

  • Slots

  • Pockets

  • Precision holes

  • Threaded holes (UNC/UNF threads available)

  • Contoured surfaces

  • Complex geometries

These components are widely used where high accuracy, electrical conductivity, corrosion resistance, and machinability are essential.

Frequently Asked Questions (FAQ)

What are Brass milled components?

Brass milled components are precision parts manufactured using VMC or CNC milling machines where cutting tools remove material from Brass blocks to create complex shapes and profiles.

What is the difference between CNC turning and milling?

Turning rotates the workpiece while milling rotates the cutting tool. Milling allows the production of complex geometries, slots, and surfaces.

Which Brass grade is best for machining?

C36000 Free Cutting Brass (CDA 360) is the industry standard in the USA due to its excellent machinability and surface finish. It is the most widely used Brass alloy for CNC and VMC machining in North America.

Can you supply custom Brass milled components to US drawings?

Yes. We manufacture custom Brass VMC parts based on ASME/ANSI drawings, CAD files (STEP/IGES/DWG), or physical samples. We work to inch or metric dimensions.

What tolerances can you achieve?

Our VMC machining can achieve tight tolerances up to ±0.01 mm (±0.0004 in) depending on part geometry.

Do you provide material certifications for US customers?

Yes. We provide ASTM-compliant mill test certificates (MTCs) confirming chemical composition and mechanical properties with every shipment.
