How to improve the finish of CNC 4-axis machining?

CNC 4-axis machining technology, data, and tools all have an impact. The general CNC 4-axis machine tool can reach Ra1.6, and the precision high-speed machine tool for aluminum can reach Ra0.2. There are markings and the finish is not high. There are many elements. If you are a long shaft, it may be that the tailstock is not working well or the tailstock is moving. If there is no problem with the tailstock, the tool wear, including machining parameters, cutting fluid and many other problems.

There is also the information of the part, and the corresponding selection tool. In addition, it includes the problem of the machine tool itself, which can only be dealt with in practice. There is no way to deal with it just like this. I hope you can find the reason for it. The main reason is because of the strength of CNC 4-axis machining. It may be that the length of your CNC4-axis machining parts is too long, or the length of your tool is too long. The center of the tool is high. Choose the right tool. Some CNC 4-axis machining speed is too high, causing the resonance of the machine tool and the parts and tools will also show markings.

How to improve the finish of CNC 4-axis machining?

First of all, you must ensure that the stability of the lathe is good or not is the fixed condition of the lathe. Secondly, will the spindle vibrate when it is working at high speed, and secondly, the coolant is very important.
Then your tools should be well ground, and the chip flutes should be opened well to avoid scratches on the workpiece due to poor chip egress, and the chamfering of the turning tool is made into an arc angle, and the other is not to resist the tool when installing the tool. .
The final thing is to match the spindle speed and the feed speed. If your lathe is not working well, it is recommended to buy some sandpaper to make it. When the sandpaper is made, it is recommended to handle it according to the working direction of the turning tool, so that the processed texture is better. .
