Hi! Im wondering if anybody has experience with using larger endmills (such as diameter 6mm / 1/4") as it seems possible to install on the spindle (NR-2551 NSK Spindle for V2-50CHK)? I have a CHK collet for 6mm diameter.
I couldnt find any information on the forum or datasheets. I inserted a D6 shaft 5mm endmill but during the spindle warm-up experienced audible vibrations at higher rpms so I canceled it. I tried to adjust it more inside the collet but couldnt hear any difference. I was thinking to try milling aluminium with this endmill (with, of course, small cuts) as it would have longer reach. Anybody with more experience?
