I have a nick in the contact points of two ball screws. Probably caused by a mechanical lockup of the machine these came from.
The ballnut travels smoothly and freely during the entire range except one location on the screw, thus my deduction on being due to a nick/dent. The ball nut still travels over the area without locking, but it vibrates badly. Inspecting that location, sure enough, there is a single nick in the edge (contact point) of the screw.
Is it possible to repair this somehow. I assume its impossible for a hobbiest as it would have to be reground and larger balls used?
I already cleaned and polished the screw...I feel like the other parts are smooth but the nicks still vibrate the nut.
The screw is an NK C3T, 0.55" diameter, 18" long ground (not rolled). The nut is an external return, single return, single nut.
Anyone know the approx. price of some of the ballscrew repair services?
