The benefits of CNC machining brass

Brass is a special copper alloy. Brass is an object made of an alloy of copper and zinc. It is named for its yellow color. The melting point of brass with a copper content of 56% to 68% is 934 to 967 degrees. Brass has good mechanical properties and wear resistance. Due to its unique advantages, brass has become an important part of the parts manufacturing industry, and is generally used for precision copper parts such as auto parts, medical parts, and electrical parts. Brass CNC fabrication offers many advantages over other metal CNC machining processes, which is why the demand is there. This article discusses several benefits of CNC machining with brass.

Several potential advantages of brass CNC machining

The following tips will help you understand why brass CNC machining will not go out of style.

1. High-speed machining

Brass has excellent machinability, sometimes referred to as 100% machinability. The mechanical properties of this alloy are high strength, high tensile strength and shear resistance. These properties help increase machining speeds when using brass. Research shows that machine shops can and should process material at feeds and speeds (typically 5 to 20 times faster) than current productivity and profitability growth.

For example, today’s brass rod material is not only easier and faster to machine, but also has no negative impact on tool wear, part surface finish or chip formation. With the power and robustness of the latest high-speed machines, the shop can increase the removal rate of brass workpiece material in milling, drilling and turning operations. Moreover, according to research, alternative materials such as steel and stainless steel also lack the competitive high-speed machining advantages brought by brass.

2. Accuracy

Brass is known for its dimensional stability and is also suitable for manufacturing with tight tolerances. Brass components remain dimensionally stable due to the small deformation coefficient and high impact resistance.

In manufacturing, chip formation is negligible, so tool wear is minimal. Typically, brass bar workpieces are the first choice for CNC machining. These workpieces are highly compatible with various CNC machining tools. Tool durability and frictionless machining increase machining efficiency.

As a fast and precise machining process, brass CNC machining can improve machining efficiency. Brass is a relatively economical and convenient material, so it is conducive to the capital investment of processing materials. The durability of the tool during this process is high, thus reducing the cost of frequent tool changes. Furthermore, no post-processing is required during this process. Together these factors lead to higher productivity and profits.

Brass is a copper alloy that retains the chemical or physical properties of natural copper. However, some properties of this alloy are enhanced. Therefore, the materials in this process are environmentally friendly. In addition, brass CNC machining does not inject any harmful gases or chemicals into the environment. Brass is also 100% recyclable. Brass' high scrap value enables manufacturers to cover most of the initial raw material costs through scrap buyback programs, and then process the scrap in scrap to produce new brass again and again without losing the material's properties. .

3. Easy to process:

Brass is a versatile material that is easy to machine with precision. Brass has good ductility and ductility, so you can get brass auto parts in a variety of shapes, sizes and surface finishes.

4. Heat resistance

Brass has a high heat resistance, allowing parts to work properly even at high temperatures.

5. Corrosion resistance

Corrosion can cause parts to wear out, shortening their service life. Brass parts are rust resistant due to the corrosion resistance of brass. This means less maintenance for these components, which can greatly reduce later maintenance costs.
