    Hi,

    Think it could also be a faulty relay.

    If you have two of the same type in the machine try swapping them and see if the problem moves.

    Then the balance is gone again.

    I think a toolpost grinder doesnt have the rpm needed for internal grinding.
    I have some internal grinding spindles, varying from 18000 to 32000 rpm.

    Maybe a dremel like tool would be better?
