Brass machining

Brass is one of the easiest metals to machine, making it great for CNC machining. Brass also has other very useful properties making it great for different industries such as plumbing, electrical and medical. Overall, it has great durability. It being so versatile and easy to work with is what makes it such a common metal for parts in a wide variety of applications. CNC machined Brass parts begin as a raw piece of metal which is cut down bit by bit to create a desired shape or object. This process is done most accurately with a CNC (Computerized Numerical Control) machine which can produce almost any three dimensional object designed via CAD (Computer Aided Design) software.

Brass machined parts

We offer a complete CNC machining service for brass parts and can produce complex Brass parts in Brass C360. Brass parts are great for applications that require high strength, corrosion resistance, a low friction coefficient, electrical conductivity and overall versatility. We work with almost every kind of CNC mill and turning center, and are able to machine whatever you need, from simple, ‘as-machined’ workholdings to complex, organic geometries with tight tolerances. When creating Brass machined parts with us, you can apply up to 6 different post-processing/surface finishing options including bead blasting, powder coating, smooth machining and polishing.

Brass parts manufacturer

Our broad network of manufacturing partners contains over 240 Brass parts manufacturers. This provides us with a huge capacity for production and a wide range of machinery meaning that we can always fulfill orders and produce highly complex parts. Our CNC machine shops can produce custom Brass parts with CNC turning machines and 3 & 5 axis CNC milling machines. Our manufacturing partners offer CNC machined Brass parts in C360. Our network of manufacturing partners is vast and global meaning that we can produce parts locally to you and also produce parts overseas for faster lead times.

Brass FAQs

  • Which quality standards do cnc brass parts comply with?

    CNC milled brass products strictly comply with the following quality standards:
    ISO 9001 – a universal quality standard that outlines numerous quality management systems and processes.
    ASTM International – a quality standard agency that creates and publishes voluntary control according to a number of technical specifications for systems and products.
    CE Mark – a mark of quality, which proves the parts conform to the required health, environmental, and safety standards.
    PMPA – a quality standard agency, which oversees production of different types of precision machined products
  • What is the cutting speed for brass?

    Cutting speeds for brass using a plain high speed steel cutter are 90-210 MPM (meters per minute) and 300-700 SFM (surface feet per minute).
  • Is brass easier to machine than aluminum?

    Brass is one of the easiest materials to machine, especially in comparison to aluminum. Where aluminum can often stick to machining tools, brass seems to adhere to tools less during machining. It is a metal alloy made of copper and zinc and is one of the most highly used materials in the world, but is still underutilized in the US in machining.
  • What are tips for CNC machining brass?

    These tips will help you experience more success when CNC machining brass:
    Carbide cutting tools or cutters with carbide inserts can improve the material removal rate and extend the tool life.
    Allow mills to run a higher speed.
    Use spindle liners to protect the equipment, workpiece, and machine operators.
    Faster machining speeds and higher quality in brass turning or milling can be achieved by reducing the clearance to damp vibration and eliminating the bar whip.
    Proper programming is essential in cnc machining brass, for example, using the proper G-code to set spindle speed and operations based on the requirements of your project.
