CNC four-axis machining technology, data, tools have an impact on the surface of the part. The general CNC four-axis machining machine tool can reach Ra1.6, and the precision high-speed machine tool for processing aluminum can reach Ra0.2, and the finish of the markings is not high. There are more elements, if it is a long shaft class, perhaps the tail seat top force is not good, or the tail seat is moving, if the tail seat is not a problem, the tool wears, including processing parameters, cutting fluids and other aspects of the problem.

       There is also the information of the parts, corresponding to the selection of tools. Moreover, it contains the problem of the machine tool itself, which as long as it is handled by grope in practice, there is no way to deal with it alone. The main reason is because of the CNC four-axis machining strength problem, it may be that the length of CNC four-axis machining parts is too long, or the tool length is too long. The center of the tool is high, choose the right tool.

       Some CNC four-axis machining speed is too high, causing the resonance of the machine tool and parts and tools will also show markings. To ensure the stability of the lathe is not good. Then there is whether the spindle will flutter when it is working at high speed, and secondly, the coolant is very important. Then the tool should be sharpened, and the chip removal groove should be opened well, so as to avoid scratching of the workpiece caused by poor chips, and the rounded arc angle of the turning tool chamfer, and the other is not to resist the knife when loading the knife. Is to match the spindle speed and the speed of the knife, if the surface effect of the processed parts is not ideal, you can buy some sandpaper to polish the surface, in the sandpaper sanding needs to be processed according to the working direction of the turning tool, so that the texture processed is better.
