Copper strip is a kind of pure copper, which can be approximately considered as pure copper. It has good electrical conductivity and plasticity. This metal material has excellent thermal conductivity, ductility and corrosion resistance, and the trace impurities in it have a serious impact on the electrical and thermal conductivity of copper. The solid solubility of sulfur, selenium and tellurium in copper is very small, and they can form brittle compounds with copper, which has little effect on the electrical conductivity, but can reduce the processing plasticity. The following is to talk about the processing characteristics of red copper belt:
1. The intersect position of the two edges of the ball tip knife for finishing should be thin. Such a cutting tool is sharp, reducing the friction during processing. In the processing of small curvature position, the processing effect is good.

2. The length of the tool should be as short as possible, or the use of a relatively thick tool rod to improve the strength of the tool, reduce the deformation of processing. This has a great impact on the finish of the workpiece.

3. The characteristics of the copper belt material itself is relatively soft, and relatively sticky. In processing, be careful to use sharp knives. Now some tool manufacturers for copper processing, specially use ultra-fine carbide materials grinding tools, processing effect is better.

4. In the processing of copper materials, the cutting line speed has no obvious impact on the life of the tool. That is to say, when processing copper materials, the spindle speed can be adjusted to a large range. Generally speaking, the φ6 flat-bottom knife is used, and the spindle speed is about 14000 (RPM).

5. The chip breaking characteristics of copper strip material are not good, and it is easy to form long chips. Therefore, the front tool surface of the processing tool must be smooth, so as to reduce the friction between the chip and the tool. This point is also more important, it has a greater impact on the use of the tool.

6. For their own grinding tool in the processing of copper material, the rear Angle can be a little bigger, improve the sharpness of the tool. Also pay attention to the polishing of the front blade face. The fine particles of a grinding wheel are needed to make a sharp cutting tool. Point point, point point Angle is smaller, so the processing effect is better.
