| X2 CNC mill overhaul |
| << < (2/7) > >> |
| Brass_Machine:
So, last night I cleaned up the mill. This is how she looks right now... The first thing I am going to do is work on the Y bearing block. The stock "block" isn't really a bearing, more of a guide hole. I have already had on fail on me. I want to keep the existing motor mount. So what I am going to do, is build a bearing block to hold some thrust bearings. Sort of like what Hoss did on his conversion but with mine belt driven like it already is. So a chunk of aluminum went on the band saw to cut to a closer size. A short while later, I had a smaller chunk. Tossed it on the mill, squared it up and cut it to size. That little guy should fit perfectly into the spot of the old bearing. Hopefully tomorrow or Saturday I can finish drilling the mount holes and boring the bearing pockets. Eric |

Have you thought of reversing the steper motor at the same time , also when I did mine (But X1 ) I fited ball races and thrust bearings it made it so smooth and got rid of a lot of the slop, I also turned an adapter that fitted over the nut for ajustment to take a handle (folding ) so it could me used manualy,it is held on with 4 m3 cap screws not fitted in the pictures , the main thing is it makes it more compact so you can fit it in to a cabnet to stop the swarf and the noise when CNC'ing. it all worker well as a power feed but because I was unable to sort out the nut on the screw (it was cast iron) it had to much back lash, with what I know now it could probeley have been sorted but I sold it. &feature=related :ddb: :nrocks: :ddb: Peter :ddb: :nrocks: :ddb: |

Excellent timing! I just got my X2 out of the wooden crate where it's sat since I moved 9 months ago. I planned to pull it apart to adjust/clean everything and then tram it but I might wait a little while to see how this thread pans out. So hurry up and finish! :bow: |

That is one of the reasons I am keeping the belt drive. I look at other conversions with the stepper just hanging off into space. Ascetically, it just kind of looks goofy. I don't know if I will be able to reverse the motor. I hadn't thought about doing that. Not sure if the table and other mount will get in the way. I am keeping it on the left side of the table. --- Quote ---... I fited ball races and thrust bearings it made it so smooth and got rid of a lot of the slop... --- End quote --- Looking at your pictures, I see both. I was wondering if I should as well. Looking at what Hoss did to his, he just used 2 sets of thrust bearings. I have the thrust bearings... but now I wonder if I should get a ball race to fit between the two. I may already have one. Will have to check my stock. All good ideas. Thanks! |

get a bearing with flanges if you have a thin plate then you can sandwich the bearing and have one thrust touching the bearing, mine has blocks the same as you to replace the original part not the block shown with the thrust race but one about the same size as you used then the plate just needs a through hole or steeped for bearing, the block shown in pic 0016 was for a directdrive for a mate, again it had bearings and thrusts. :ddb: :nrocks: :ddb: Peter :ddb: :nrocks: :ddb: |
