Precautions for cnc mini metal lathe processing copper precision parts

For copper precision parts with high surface quality and appearance accuracy requirements, they should be ground and processed according to the precision machining process to meet the quality standards. However, the manufacturing process of general parts cannot be applied mechanically, and it is not only difficult to solve the problem of grinding debris clogging the grinding wheel. In addition, the surface of precision parts will appear rough and scratched, resulting in a decline in the quality of precision machining. The following introduces the precautions for precision copper processing

Precautions for precision copper parts processing

According to the properties of copper, the first consideration during processing is its ductility. We all know that workpieces with better ductility are softer. For soft copper parts, it is difficult to process with AldoosanleCNC high precision cnc lathe, which requires AldoosanleCNC flat bed cnc lathe machine to process the copper parts. In the processing of copper parts, there are two very important factors. The first is the feedrate when cutting, and the second is the feedrate when cutting. These two factors are very important and they are also the two key factors that are especially pointed out in the process of processing copper parts by AldoosanleCNC cnc lathe manufacture.

A very important factor for copper is its low hardness, which is prone to problems during machining with AldoosanleCNC cnc lathe machine. Copper is softer and chips tend to stick to the insert, affecting the quality of the machined surface and the durability of the tool. In addition, the surface of the workpiece processed by AldoosanleCNC cnc lathe is prone to water ripples and noise. Pure copper has a large expansion coefficient and is easily deformed by the cutting temperature, so it is difficult to control the finishing size and geometric accuracy. If pure copper contains free-cutting elements such as sulfur and pulverization, its machinability will be exposed. The toughness and plasticity of copper are relatively large. The thermal deformation during cutting is large, which requires the AldoosanleCNC mini cnc lathe machine to have a sharp tool, light cutting, smooth chip removal, and minimize the cutting temperature.

When AldoosanleCNC cnc mini metal lathe is used in the processing of copper workpieces, with the increase of cutting speed, the cutting force decreases accordingly, thus greatly reducing the cutting deformation coefficient of copper workpieces. The surface quality of high-speed milling of copper alloys is very good, saving subsequent finishing operations. When cutting copper parts, the surface quality increases with the increase of the cutting speed and decreases with the increase of the feed rate. However, in high-speed machining, increasing the feed rate has much less effect on surface quality than in low-speed machining.
