What is Brass CNC machining?

Brass CNC machining is a specialized manufacturing process that uses Computer Numerical Control (CNC) technology to automate the cutting, shaping, and fabrication of brass machine parts. The finished brass parts have a high degree of accuracy and precision that will be otherwise difficult to achieve manually. While there are several established advantages of manufacturing brass parts using CNC machining stainless steel, certain considerations are necessary before actually embarking on the machining journey. These considerations include the properties of the brass itself, the different brass grades and types, and the right CNC technique.

Key Properties of Brass that Make it Suitable for CNC Machining

Despite the advantages of accuracy, speed, and efficiency of brass CNC machining over traditional machining methods, not all metals can be CNC processed. However, one of the suitable metals for CNC machining is brass, and this is due to its great properties.

Excellent Machinability

Machinability is the ease with which a material can be cut (machined) with a cutting tool. The higher the machinability of a metal, the easier the large-scale production of the metal’s parts. Brass is known for its excellent machinability, making it ideal for brass CNC machining. One of the reasons for the high machinability of brass is its lead content.

Corrosion Resistance

Brass has high corrosion resistance, which is always desirable when manufacturing parts. The primary reason for brass’s high corrosion resistance is that it is a non-ferrous metal, which means it does not naturally contain iron.

While there may be iron among the brass CNC machining components, depending on the alloy type, this amount is too small to alter the corrosion resistance of brass. Further, the high copper content and presence of aluminum in some brass types can form protective layers around the metal, further boosting its ability to resist corrosion.

Aesthetics

Aesthetic appeal is one of the essential properties manufacturers consider in CNC brass machining. Therefore, it is unsurprising that brass is common among CNC manufacturers, as it has a visually appealing golden hue. While bright gold is the most common appearance, depending on the constituents and proportions, brass can also be reddish gold, silvery-white, or rose gold.

Physical appearance also goes beyond color, as factors like texture and surface finish also contribute to aesthetics. Brass also excels in these properties, justifying its use in brass CNC machining for decorative purposes.

Malleability

The malleability of a metal is its ability to be drawn into wires and different shapes without breaking. Brass is a very malleable metal, making it an excellent candidate for CNC Machining Parts, as machinists can easily manipulate it into desired shapes.

The high malleability of brass is due to its high copper content (67%), as seen in copper CNC machining. Therefore, brass alloy types lower in copper content will not be as malleable as others.

Conductivity

Brass has higher thermal and electrical conductivity than many other metals, and this is also due to its high copper content. In CNC machining, materials with high electrical conductivity are not only useful in designing specialized conductors but also for their ability to dissipate heat.
