This year we bought NVX 5100/50 with Celos. After 8 days of hard work the spindel broke down. During the milling the nut which hold the die tool loosened. This caused the formation of the axial force and broke the bearings of the spindle. Fortunately the machine is under warranty and the service in Poland works quite well. They fixed this very quickly. Did anybody have similar issue with the NVX machine ?
