Diy 5th axis trunnion build part1

[@Svanitterzon]

The model is now available for download on Grabcad: grabcad.com/library/5th-axis-trunnion-cnc-1

[@josepenaherrera6354]

thanks, man. it is very useful. Since you used harmonic drive, why didn't you use their direct drive servos ?

@@josepenaherrera6354 thank you

Thanks

Gday, this is going to be a great series to follow, no need to change anything that I can see, throughly enjoyed watching, cheers

[@AlexCNC]

Can't wait to see it finished :)

[@ActiveAtom]

This shall be a GREAT build and a fun project to join you in and follow while you make this build. Lance & Patrick.

[@Svideoplayer]

Klasse Stef, zeer benieuwd naar de rest.

[@justinmoritz6543]

Wow this is an incredible project! I will be following closely as I would also like to make a trunnions one day!

[@bobweiram6321]

It would be very helpful if you created playlists of your videos organized by topic in chronological order. It also helps increase your view counts and engagement.

[@Ale_Lab]

What an amazing series! Waiting the 2nd episode so badly :-)

[@max_eley]

You are a very talented man, good stuff!

[@mattbentley8958]

Thanks for the video. I am making a trunion similar to this. Is there a place. Where I could access your documents on this project? Cad files and part numbers. I am not sure what bearings to use for the A axis. I will be using a 45 size harmonic drive for the A and a 40 size harmonic actuator for the C axis. Direct drive for both. Thanks

[@Svanitterzon]

Hey Matt, you can download the 3d model on grabcad. I don't really have a parts list. grabcad.com/library/5th-axis-trunnion-cnc-1

[@Cretan-un6ul]

hey mate thanks for sharing, your spindle have a port that blows air down to the tool holder. not the one inside the cone. there are 6 screws where the flat spot is. Where is stuck the indruder. Also this 6 screw are connected to a port on the big diameter right up. Mine have it anyway and I have the bt30 as well. check it out.

[@Svanitterzon]

I need to check it then. I never found this port while i really would like to have it😬

[@Svanitterzon]

My spindle doesnt have a blowoff channel unfortunaly.

[@Cretan-un6ul]

@@Svanitterzon you must make up something for this. You get chips going on soon or later. Make a ring mounted on the spindle. blowing a little more air inwards. mine uses low air pointed exactly. so..

[@DonStinger]

Cool project. Do you know what is going on with the noise while the spindle is idling? Sounds like bad bearings. I hope not :) Edit: Just saw your explanation in part 2

[@vollverfraest2880]

What you build is awesome!! I'm looking forward how it will turn out.

[@KamalSingh-ny9vw]

what i really wanted to see from the first day that , will it be able to cut steel ???

[@markbrebner5792]

Looking forward to seeing it finished awesome work have fun.

[@lukebm5555]

You could make a clear view screen for your camera? It’s basically a clear spinning disk to throw off liquid, mostly used on boats.

[@serg9176]

Hi! What metal did you make all the parts of this machine from?

[@moscowtime8876]

Hello! Can you answer how much it cost at that time? Or maybe you can upload the list of materials (BOM) ?

[@joesmith2465]

cant wait so see how this goes i made my 4th 5th maybe next!!

You know how much I wish you did such videos for the mill build, right?! 😉 So, you know how great it is to share this build like this ❤️🙏 Footage is absolutely OK 👍 Design is very nice and, if I'm not fond of belts, I believe you could change my mind... 3 questions on the machining side: Do you really need to peck with the drill? Why adaptive strategy instead of contour or bore ones for counterboring? Can't you take full depth roughing cuts on the sides? Thanks again for taking the time and energy to share this with us. So inspiring, as always...

[@Svanitterzon]

Thanks! About the machining I'm still in my comfort zone and afraid to take a real bite. There must be a day coming that i just need to try and plow an endmill tough material and see how hard i can go. Same for the counter bore. The adaptive is the most reliable operation which almost never goes wrong.

@@Svanitterzon reduce your WoC to 3% tool dia with full DoC and crank up your feeds and speeds. Then increase WoC slowly until you get the good feeling... You won't regret it. Seeing your machine running into mater joyfully should be a satisfaction like no other, plus, you'll increase your MRR and tool life! High Speed Machining FTW my friend 👌👍

[@localhawk1]

Thanks for sharing. Beltdrive through harmonic drive ;) never seen

[@MilitarizmTR]

Hi. How much are you selling it for?

[@PWLopes9000]

Good job, looking forward to see the next parts and most of all how it behaves in practice with the belts, etc. what bugs me the most with the 5 axis is the work to set it up and take it out. Been thinking all along of using shunk or other zero point clamp to make it easier. I have even considered just a d1-4 cam plate. The other issue is fusion limitations. But I saw you have the education license?

[@PWLopes9000]

Oh yeah forgot to mention that you could use a programmable coolant nozzle, I certainly need one and am building a small series of them.

[@Svanitterzon]

Thanks, i gone try to keep the trunnion on the table all the time and give it a g55 or so. Since eding doesnt support tcp i need to set my zero point at the axis and the rest need to come from the cam software. I want to make my own dovetail clamp once thats all setup good i assume it will be easier in the future. Yes i have an education licence but i think i all need is the 3+2 funtion that would be already more then enough to start with. I have been looking at programmable nozzle before. Sounds like a fun project to do later on.

[@kwk8363]

Great video! Did you saw what AvE come up with? He made rotating lens for his go pro, It works very well, maybe a little side project?

[@DjViOd]

Mooie machine Stef! Waar haal jij je gezaagde en gevlakte plaat vandaan?

[@Svanitterzon]

Ik haal dat altijd bij Cmd die hebben sinds begin dit jaar ook een webshop. onlinealuminium.nl

[@kwk8363]

What pump do you use? What is the pressure and flow rate? I'm looking something for my mill and yours seems to be perfect

[@Svanitterzon]

Im using this pump, when i first received it i tough i have been pranked because its pretty small but it seems to be just right for the job. koelpomp.nl/product/koelpomp-sap-pa-70/

[@andysierra4388]

This is increible , good look you project men .

[@Thorhian]

This is awesome! I'd highly recommend trying to balance your audio so that your voice doesn't mostly just come of the right side of my headphones. However, I'm really excited to see this progress!

[@Svanitterzon]

I record the spoken video's with my phone seems like i am blocking the left side microphone with my hand while holding it... I will try to keep it in mind for next time.

[@msdesignru]

[@testyourdesign233]

Great start. 👍

[@AsitShouldBe]

Nice idea but i have some dubt: belt drive is not backlash free and not free from vibrate under stress, you need some harmonic reduction and closed loop servo .. just my opinion, bye friend

[@Svanitterzon]

Iam using harmonic gearboxes with servo's that have encoders?

[@AsitShouldBe]

@@Svanitterzon yes but belt too.. not good for me.. your machine is pretty strong, the belt driven movement will be a weak part of the system..

[@etch3130]

@@AsitShouldBe a belt driving a 100:1 harmonic drive will not be an issue.

[@AsitShouldBe]

@@etch3130 yes you are right but i hate belts.. 😁

[@Sketch1994]

@@AsitShouldBe Belts are awesome! They are not as elastic as people think and belts don't have the backlash of chains and you can run them pretty tight

Hey Stef gr8 build, hey how do I get in touch with you Plz

[@jdmorgan82]

Why does your spindle sound like that? It sounds unhappy.

[@vladbilas2743]

Что за дребезжание при нагрузках на шпиндель?

[@emzyfilm6492]

what happened to your spindle bearing ? sounds very bad

[@Svanitterzon]

Yeah i should said it in the video. The action camera microphone sucks. Its inside a case which is mounted to head with a thin piece of square aluminium. It vibrates and gives a super raw noice. This is not the sound hear when next to the machine!

[@ray-charc3131]

How much do the harmonic drives cost?

[@Svanitterzon]

I get them secondhand for 250 euro each.

[@rdc02271]
