Hello guys, i have a diy cnc router that is machining aluminum and i am having some troubles with chip welding at pockets and other operations. I am using a 45° helix mill, 3 flute, polished from ISCAR, it's doing a pretty job, but sometimes it run into trouble. Do you guys have any solution to improve it's performance? I was thinking of a coating.. or going for two flute endmills. I have with me an image and a website about coatings, but i didn't understand them very well, from these coats, does any of them improve ?
This is the website: Titanium coatings TiN, TiCN, TiAlN, AlTiN - HANNIBAL CARBIDE TOOL, INC.
The ZrNbCn seens to be the best for aluminum, it says wet or dry, have anyone here used it ?
