- In this episode we're covering the steps to follow in order to replace the spindle arbor and bearings assembly on a Bridgeport Milling Machine.
I wanted to address the some noise coming from the head when the high gear is engaged, and knowing that my old spindle arbor has a slight bend in it (by the spline) I thought it might help to get a brand new assembly to test the machine with.
Take a look at the video to see how it goes.
You may find this video useful also if you have to replace the bearings in your milling machine!
There is more work planned for the head of my milling machine so stay tuned for future updates! - วิทยาศาสตร์และเทคโนโลยี
HI Stefano, cool that you made this video. You did well.
Cheers,
Mark
I’m still very much a rookie! Thanks!
@@stefanobertelli2650 Keep going. You will do well.
Grate video:) can't wait for more
Thanks!
To me, it sounds like the dogs on the spindle hub are worn out.
Where did you get the new spindle from? They are not interchangeable with the import spindles which are made for Bridgeport clones.
That’s definitely the issue, i’m gonna replace those next! Thanks for the feedback, the spindle is from amazon, jist one of the clones available for cheap.
@@stefanobertelli2650 Note that there are two parts that mesh with drive dogs. The Spindle Pulley Hub, and the Splined gear hub. These parts are very expensive. I have seen people re-flle them to fit tight, but I don't know if that is a good repair or not. When new, the tapered dogs do not mesh all the way to allow for wear. Again, note that the import parts will not fit the Bridgeport. You can check for wear by looking through the air vent at the top of the speed dial. Note the mesh and rock the spindle back and forth. Also, if there is less or no noise when in Back Gear (low speed) since they come out of mesh. Regards
