BP boss cnc ball screw backlash. How much is too much?
1475. My 1987 Taiwanese Webb mill was originally a CNC conversion at the point of sale, so it came to me with ball screws. The Y Axis has zero backlash and the X Axis has .007 which is no problem for manual use with a DRO. I agree with those who mentioned checking thrust bearrings since movement of the ball screw on its axis will transfer into ...

Hurco VM2 backlash
A ball bar test revealed massive deviation from the acceptable limits. I would bet this is the exact same thing going on. You shouldn't need to replace much, but you will need to get the system dialed in and properly compensated. Getting a ballbar test is the best solution if it is in fact a backlash problem like you suggest.

That'll buff out - OX CNC - Maker Forums
The sides have a 2.2° draft angle, so a ball mill seems necessary to avoid a stepped finish. But now that I understand (I think) why the carbide bit exploded, maybe I should get a 4mm 2-flute flat endmill to rough, and use a 4mm ball mill to finish, so I don't have those pockets. With that I might even be able to rescue this part.

How can I reduce or eliminate the backlash in a ball screw ...
A ball nut with all the backlash removed is called preloaded. There are several ways to reduce or eliminate the backlash in a ball screw assembly: At the factory level we can select ball sizes to minimize the backlash. This works well for small lead to diameter ratios, like a 5x25mm. In some cases we can preload a ball nut in this way.
