    Looking some spindle high speed to purchase

    Hi, i made an smal CNC machine to make max 20x20cm PCB prototypes. My problem is to get an good high speed spindle with low runout.

    I tested an dremel one and at high speed have a lot of runout :/ i tested an chinese one like this one https://www.aliexpress.com/item/1pcs...779665925.html but noise is high and roundout looks high too.

    Some recomendations about from where can i purchase some spindles?
    Thanks

    Hi,
    I use one of these:

    https://www.mechatron-gmbh.de/filead...FS-6508-AC.pdf

    Being German made they aren't cheap but really nice to use. The same company has higher speed (up to 60,000 rpm) if you have
    the budget.
