Can you take a picture of your setup and post it? When I look at the spindle kit (Sorotec Online-Shop - Mechatron,China,Elte Spindel,Suhner Frässpindel,Isel) I only see the mount, the VFD and the spindle. I’d love to see whatever else that comes along.
If their water cooling is not that good, would it be better to buy a spindle (mechatron Katalog - Onlineshop - HF-Spindeln, Frequenzumrichter und Komplettsysteme fuer CNC) and a VFD from them and then figure out the cooling system myself?
