In the field of CNC prototype processing, copper and brass exhibit different processing characteristics from materials such as 45 # steel due to their unique properties.
Purple copper is known for its extremely high electrical and thermal conductivity. In CNC prototyping, this feature brings both advantages and challenges. High conductivity makes it an ideal material for manufacturing prototype parts such as electrical connectors and conductive molds, ensuring stable current transmission. However, during processing, its good thermal conductivity can rapidly conduct heat, leading to a rapid increase in tool temperature, accelerating tool wear, and affecting machining accuracy and surface quality. Moreover, copper is relatively soft and prone to sticking during cutting, resulting in an increase in surface roughness during machining. To address these issues, it is necessary to use tools with high sharpness and good heat dissipation when processing copper, control cutting speed and feed rate reasonably, and adopt appropriate cooling and lubrication methods.
Brass has good processing performance and a certain strength. It has slightly higher hardness than copper and relatively lower cutting resistance in CNC machining, enabling a smoother cutting process and producing parts with better surface quality. Brass is commonly used to manufacture prototypes for various decorative and hardware accessories. However, attention should also be paid to brass during processing, as the cutting performance of brass with different compositions varies. For example, brass with higher zinc content has better cutting performance, but its strength may be reduced. In addition, brass may produce small chips during the processing, and if not cleaned in time, it is easy to scratch the already processed surface.
Overall, both copper and brass have their own unique characteristics in CNC prototype machining. Processing personnel need to fully understand their performance characteristics and adjust the processing technology and parameters accordingly in order to fully leverage their advantages and produce high-quality prototype parts.
