This week, YIJIN Hardware introduces you to the precision copper parts. Most of the products we released before are aluminum alloy and stainless steel. Many customers think that YIJIN Hardware only processes stainless steel material. In fact, YIJIN Hardware has enough capacity to process copper, aluminum alloy, stainless steel, iron, and other materials. Today what we show are the precision copper parts processed by YIJIN Hardware’s four-axis CNC machining center.
Attention Points of Precision Copper Parts Processing
According to the characteristics of copper itself, the first thing to consider in the process of processing is the ductility of copper. We all know that the better the ductility of the workpiece, the softer it is. For soft copper parts, it is difficult to process lathes, which requires CNC lathe processing of copper parts. There are two points that are very important when processing copper parts, the first is the feed rate during cutting, and the second is the feed amount during cutting. This is the copper parts CNC lathe machining process especially pointed out two key factors.
A very important factor of copper is that its hardness is relatively low, which is very prone to problems during processing. Copper is soft, chips are easy to bond on the blade, affecting the quality of the processed surface and the durability of the tool, and the surface of the machined part is easy to produce water ripple waveform, and will emit noise. The expansion coefficient of pure copper is large, and it is easy to deform under the influence of cutting temperature, and it is not easy to control the finishing size and geometric accuracy. If pure copper contains free-cutting elements such as sulfur and zinc, it will change its machinability. The toughness and plasticity of copper are relatively large, and the thermal deformation during cutting is also large, so the tool is required to be sharp to achieve the purpose of light cutting and smooth chip removal, and to reduce the cutting temperature as much as possible.
When using a CNC vertical machining center for high-speed milling of copper parts, with the increase of cutting speed, the cutting force should be reduced accordingly, which can greatly reduce the deformation coefficient of copper machining parts. The surface quality of high-speed milling copper alloy is very good, which can save subsequent finishing; When cutting copper parts, the surface quality increases with the increase of the cutting speed and decreases with the increase of the feed speed, but in high-speed machining, increasing the feed speed has a much smaller impact on the surface quality than at low speeds.
DMG 4-Axis CNC Machining Center
This time, the precision copper parts are processed by the Demag four-axis CNC machining center. The processing table is 850 mm, the processing stroke is X/Y/Z=850/550/550, and the processing accuracy can reach ±0.01 mm. After the machined part is clamped, it can complete the process of turning, tapping, milling, boring, reaming, and other processes, especially in drilling and tapping, it has a very special speed and affects performance. Suitable for machining various precision parts.
