Hi all,

Been test cutting aluminium flat bar (about 5mm thick) with different sizes of 2 flute HSS endmill. But the cut produces a lot of vibrations. So much so until the screws at the base of my quick vise was shaken loose. In fact the table was shaken loose as well. I have already bolted the mill down. If I hadn't, the vibration was worse.

My question is this the result of using 2 flute end mill? I have seen X2 cutting brass and aluminium so I know it can do it.

Anyway, still getting use to the X2 and trying to cut different material and seeing which feedrate will be best for cutting different material. Thanks.

Alex
