cnc four-axis machining technology, materials, tools have an impact. General cnc four-axis machining machine tools can reach Ra1.6. precision high-speed machine tools for processing aluminum can reach Ra0.2. There is a speckle finish is not high. Factors are more, if you are a long axis class, perhaps the tailstock top force can not, or the tailstock is moving, if the tailstock is not a problem, tool wear, including processing parameters, cutting fluid and other aspects of the problem.
There is also the parts of the material, corresponding to the selection of tools. Further contains the machine tool's own problems, this as long as in practice to figure out how to deal with the light, there is no way to deal with it, I hope you can find the reason for it.
The main reason is because of the CNC four-axis machining strength of the problem, it is possible that your CNC four-axis machining parts to probe the length of too long, or your tool length is too long. The center of the tool is high. Pick the right tool. Some are CNC four-axis machining speed is too high to cause the resonance of the machine tool and the part tool will also show the speckle.
To you to ensure the stability of the lathe is good is the lathe fixed condition is good. Then is the spindle will not show chatter when working at high speed, followed by coolant is very important.
Then your tool should be well sharpened, as well as the chip groove to open well, to avoid the poor chip out of the workpiece scratch, as well as the turning tool chamfering into a rounded angle, the other is to install the tool when not anti-knife.
Is to match the spindle speed and the speed of the tool, if your lathe work is not very good, advocate buying some sandpaper to get, in the sandpaper to get the time advocate according to the direction of the work of the turning tool processing, so that the processing out of the texture better look some.
