Skills for Custom CNC Machining of Bronze Bushings

Bronze is the earliest alloy that appeared in the history of metal smelting and has been used in environments exposed to water, especially salt water. It is an alloy in which tin or lead is added to pure copper, which has special importance and historical significance. Bronze has high strength and low melting point.

When 25% tin is added to smelting, the melting point will drop to 800°C. In contrast, the melting point of pure copper can be as high as 1083°C. At the same time, bronze also has good castability, wear resistance and chemical stability. Bronze alloys are used in many different types of systems and components. Bronze is a common choice for bearings, bushings, marine components, petrochemical system components, and electrical connectors.

The properties of bronze

1. Bronze is harder than copper, has a lower melting point and is easy to melt.

2. Bronze is also harder than pure iron.

3. It can make a loud sound when struck.

The first step in developing the ideal custom CNC machining bronze bushing method is to understand the properties of bronze. The basic types include silicon, phosphorous, aluminum, manganese and copper-nickel bronze. Generally speaking, when it comes to bushings, the best choice is bearing bronze. This bronze has 6% to 8% lead, which means it is durable in high-friction or high-wear type applications. Although, depending on the specific application, other types may need to be considered.

Any important bronze CNC machined parts use high-quality cutting tools. The use of high-quality cutting tools at the correct speed and feed is essential for the precise measurement required to create bushings and bearings.
