Custom CNC Milled Brass Part – Electronics and Electrical Equipment

Custom CNC milled brass part with deep rectangular cavity and multiple internal features for electronics and electrical equipment

This is a custom CNC milled brass part we made for an electronics and electrical equipment application. The part has a deep rectangular cavity with multiple internal features — a raised central boss with a tube port, an oblong slot cutout, several smaller bosses, and a grid of screw holes around the perimeter. We machined the part from a solid brass billet using 3-axis CNC milling.

Brass is a copper-zinc alloy that combines several useful properties in one material. It has good electrical and thermal conductivity, which makes it a natural fit for components used in electronics and electrical equipment. It is also non-magnetic, which matters in applications where magnetic interference needs to be avoided.

Over time brass develops a natural patina, but this is not something customers need to worry about with our parts. After machining, we apply a passivation treatment to all brass parts as a standard step. Passivation seals the surface and protects it against oxidation and corrosion — parts treated this way can go up to 4 years without oxidizing under normal conditions and hold up to 96 hours in a salt spray test. It is included in our standard process, so customers get that level of protection without needing to specify or pay for a separate coating or plating operation. If a different surface finish is required — such as nickel plating, chrome plating, or clear lacquer — we can accommodate that as well based on the customer’s specifications.

Project Details

Part type: Custom Non-Standard Brass Part

Material: Brass

Machining Process: 3-Axis CNC Milling

Surface Finish: As-Machined

Beyond electronics and electrical applications, we machine custom CNC brass parts for customers across a wide range of industries. Whether it is a simple turned component or a complex milled part with multiple internal features like this one, we work from your 3D model and machine it to your exact specifications. Brass is just one of the materials we work with — if your application calls for aluminum, stainless steel, copper, or other metals, we can handle that too.

Our Manufacturing Capabilities

5-axis CNC milling machine cutting an aluminum block during the manufacturing process.

Capabilities include 3-Axis, 4-Axis, and 5-Axis CNC Milling, as well as CNC Turning operations. Standard materials processed include Aluminum alloys, Stainless Steel, Titanium, etc. and Engineering Plastics. Available secondary operations include Anodizing, Powder Coating, Bead Blasting, and Laser Engraving.

Capacity supports requirements ranging from single-unit Rapid Prototyping to Low-Volume Production runs (1-1,000+ units).

Factory Quality Assurance

A standardized Quality Management System (QMS) is applied to all manufacturing orders, regardless of part complexity or production volume. The following inspection stages are mandatory for every CNC machining project:

  • Material Verification: Raw material certification (chemical composition and mechanical properties) is verified upon receipt to ensure compliance with material specifications.

  • First Article Inspection (FAI): The first unit from any production run undergoes a full dimensional report to validate the machining setup and programming before volume processing begins.

  • In-Process Monitoring: Periodic checks are conducted during the machining cycle to monitor tool wear and ensure dimensional consistency is maintained throughout the batch.

  • Final Inspection: Completed components undergo a final dimensional and cosmetic verification using CMM (Coordinate Measuring Machine) and calibrated manual instruments prior to packaging.

FAQs About CNC Machining Services

No. We support projects of all sizes, from a single prototype unit to low-volume production runs.

Standard lead times are typically 10–15 business days. Expedited services (Rapid Prototyping) can be completed in as little as 3–5 business days, depending on part complexity and material availability.

In most cases, we source materials from our approved suppliers to ensure quality control. However, we can machine customer-supplied materials for specialized alloys or specific requirements upon engineering review.

Unless otherwise specified, our general tolerance standard is ISO 2768-m (±0.125 mm) for metals and ±0.25 mm for plastics. Precision tolerances ±0.005 mm are achievable but must be explicitly stated in 2D technical drawings.

Our facility can accommodate parts up to 4000 x 1500 x 600 mm for milling and Ø200 mm x 500 mm for turning.

Yes. We can install inserts (e.g., Helicoils, PEM fasteners) and perform basic mechanical assembly of machined components prior to shipment.

To provide an accurate quote, we require a 3D CAD file (.step). If the part has threaded holes, tight tolerances, or specific surface finish requirements, a 2D PDF drawing must also be provided.

Not a problem at all. If you don’t have a 3D design, simply share your concept or requirements with us. We work with experienced partnered product designers who can help convert your ideas, hand-drawn sketches, or reference images into professional, manufacturing-ready 3D models.

Please note that 3D modeling services are subject to an additional design fee based on part complexity.

Absolutely. We offer full reverse engineering services for existing parts. Simply mail us your sample, and our engineering team will take care of the rest — from precise measurement and 3D modeling to final CNC production.

We take IP protection seriously. All files are stored securely, and we are willing to sign a Non-Disclosure Agreement (NDA) prior to receiving your data.

Yes. We can provide material certificates (COA) and dimensional inspection reports upon request. Please specify this requirement when placing your order.

We ship globally using major carriers (DHL, FedEx, UPS).
