Electronic copper parts

The characteristics of turning copper parts

Copper alloy machining (turning, milling) has excellent performance and low resistivity. Good ductility, high thermal and electrical conductivity, so it is the most commonly used material in cables, connectors, and electrical and electronic components. It can also be used as a building material and can be composed of many kinds of alloys. The most important of these are: beryllium copper, phosphor bronze, bronze and brass. In addition, copper is also a durable metal that can be recycled many times without compromising its mechanical turning and milling performance.

Copper electrode of EDM machine

CNC machining of copper electrode

During EDM machining, the copper electrode and the workpiece are respectively connected to the two poles of the pulse power supply. The pulse voltage applied to the copper electrode and the workpiece generates spark discharge. The instantaneous temperature of the discharge can be as high as 10,000 degrees Celsius, and the high temperature makes the surface of the workpiece partially vaporized or melted.

Micro CNC machining parts technology

Super finishing of turning and milling micro parts

The micro CNC machining technology adopts a fully automatic method to super-finish the surface of metal parts. Through a kind of mechanochemical action, the material of 1-40μm on the surface of the metal parts is removed, and the surface quality of the processed surface reaches or is better than the N1 level of the ISO standard. Micro CNC machining technology is mainly used in the two fields of ultra-precision polishing and ultra-precision brightening.

The price advantage of CNC machining mass production

What are the advantages of CNC machining?

CNC machining has become a major pillar of the manufacturing industry. This type of processing is used in more and more products (for example, CNC turning and CNC milling, engraving, cutting and drilling). Although many mechanics are accustomed to this form of processing, not everyone knows the logic behind it. Compared with other forms of machining, the main advantages of using CNC machining are as follows:
