CNC Machining with Brass
With its striking gold-like appearance and versatile properties, brass has long been favored for various industries. From electronics to plumbing, brass finds its way into countless applications, and its ease of CNC machining makes it a go-to choice for many manufacturers.
Whether you’re considering brass CNC milling or brass CNC cutting for your next project, this guide will teach you everything you need to know to maximize this exceptional material.
Key Benefits of CNC Machined Brass Products
Brass stands out for its strength, machinability, and corrosion resistance, making it one of the most versatile materials for CNC machining.
Excellent machinability: Brass is known for being incredibly easy to machine, making it a favorite for CNC milling and cutting operations. It allows for smooth, precise cutting with minimal tool wear, ensuring high-quality finishes.
Corrosion resistance: Brass is naturally corrosion-resistant, especially from water. This makes it ideal for parts exposed to moisture, such as fittings, valves, and plumbing components.
Electrical conductivity: Brass has excellent electrical conductivity, which is why it is commonly used in electronic components like connectors and terminals.
Aesthetic appeal: With its gold-like appearance, brass is often chosen for decorative parts and applications that require a polished, high-end look.

Popular Brass Alloys for CNC Machining
Brass is an alloy primarily composed of copper and zinc, but different variations of brass alloys can be tailored to specific needs. Some of the most used brass alloys for CNC machining are:
C360 Brass (Free-Cutting Brass): Known as the most machinable brass alloy, C360 is perfect for CNC milling and turning operations. Its ease of machining makes it ideal for high-speed operations , and it is frequently used for fittings, gears, and fasteners.
C464 Naval Brass: This alloy boasts superior corrosion resistance, particularly in saltwater environments, making it ideal for marine hardware, valves, and pump components.
C385 Engraving Brass: This brass is designed for intricate machining and engraving. Due to its beautiful finish and machinability, it is often used in decorative hardware, plaques, and nameplates.
Challenges of CNC Machining Brass
While brass is a relatively easy material to work with, there are still a few challenges that manufacturers face during CNC machining:
Chip control: One of the main issues with brass CNC machining is managing chip formation. Brass can produce long, stringy chips that may cause tool wear or machine jams. However, using the right cutting tools and speeds can mitigate this.
Overheating: Like many metals, brass can generate heat during CNC cutting. Although brass dissipates heat better than other metals like titanium, it’s still essential to use coolants to maintain temperature control and prevent tool wear.
Surface finish: Achieving a smooth surface finish on brass requires proper tool selection and feed rates. Brass is soft compared to materials like steel, so too much pressure during machining can lead to surface imperfections.

CNC Machining Processes for Brass
There are several methods to machine brass parts depending on the requirements of the project:
CNC Milling: In brass CNC milling, a rotating cutting tool removes material to create precise shapes and designs. This process is ideal for producing complex parts like gears, brackets, and fittings.
CNC Turning: CNC turning involves rotating the brass workpiece while a stationary cutting tool shapes it. This process is perfect for cylindrical parts like shafts, rods, and threaded components.
CNC Cutting: Brass CNC cutting uses high-speed machines to slice brass sheets or blocks into smaller pieces for further processing. This method is often used in conjunction with milling or turning operations.
Engraving and Finishing: Brass is ideal for engraving and polishing processes for parts that require fine detailing or a decorative finish. Its malleability allows for intricate designs and high-quality finishes that enhance its aesthetic appeal.
