CNC Rotary 4th Axis 20:1 Gearbox Modification (How to Remove the Backlash)

[@philflo8575]

Hi Richard, Really good video and very nice ideas and explanation. Very happy to have discovered it and I am in the process of making these modifications, otherwise the chuck is unusable to machine precise parts. Thank you again for the time you have spent to share your experience and knowledge !! Philippe from Switzerland.

Using your video as inspiration, I did a similar modification for a couple of these rotaries and I am very pleased with the results. Brilliant work here!

I couldn’t find you to n instagram. I am going to make a 4th and 5th axis for my fadal Linux Cnc build. Thank you for this video. Exactly what I was looking for.

Hi Richard. Great video, explains just what I need. Did you make your tailstock? If yes, be great if you could explain how you made it? Thanks Tom

Your years of experience served this project well! I'm surprised others on here haven't asked if you are interested in making these and selling them. I am looking to buy one for my new, incoming Shapeoko and cant add to my 'rabbit hole' list at the moment. Are you selling any of these? My Shapeoko would like to know (and it was very impressed with how quickly you tapped out that oil seal).

Great project! How do you fix the bushing after adjusting against rerotation?

Ich habe die Lagerstellen 0,1mm zum Zahnrad hin ausgespindelt und oben jeweils 2 Madenschrauben eingesetzt die die Lager zum Zahnrad drücken. Ist weniger Aufwand und nun ist es Spielfrei :-)

Hi Richard, I was trying to disassemble this same gearbox but I am not able to get the warm gear part (Shraft with the grove gear ) like you do in here (around 8:54 in the video). Any idea how to get it out. Also oil seals doesn't seam to be same in mine, I cant get them out like you do in here. Basically I cant disassemble the unit at all.

Hi, first you remove booth flanges, then push gear with press towards flange , after that you can remove worm gear also in direction where flange was atached

Richard if I wanted you to make me one would you consider it and how much?

[@metalworksmachineshop]

I want to add a rotary 4th axis to my cnc plasma table.

Ho strong are these gearboxes ?

[@juanmanuelgarciaortega2591]

Hola veo que te funciona pero no entiendo la lógica, exactamente que es lo que hace que desaparezca el juego??? La anilla esa que recortas??? Para que es el casquillo de cobre. Perdón no entiendo inglés y los subtítulos no funcionan
