5 Axis CNC Spindle Speeder | 300% Faster Cycle Time | Boost Efficiency | Pocket NC Upgrade 

The 3 Blue, 1 Brown editing style does not go unnotced. I was very suprised to see a channel with 62 subscribers making graphics as informative and accurate as these are. I haven't even fininshed the video and I'm already leaving a comment about how good it is. Theres really an art in making a video concise while also packing in as much information as possible while making the infographics and other visuals accurate and easy to digest. I am looking forward to seeing more content!!

that‘s really really cool!!! and a great budget option for V10 users haha

Always fun to see what your working on and your presentation method keeps the audience engaged. Great stuff! One recommendation....audio, something like the Rode Wireless Go 2 or similar would be perfect for your format. Looking forward to more great content!!!!!

nice spindle upgrade you've got there . I've always thought the pocket NC was an amazing little machine. Now, as an actual (former) cnc machine tool field engineer I'd like to offer a few suggestions for improvements. Firstly, the tiny little rear bearing is having to handle 100% of the axial pullout force , it should be seeing 0% and only have to handle radial loads. If you constrained the front of the outer race of the 30/8 bearing ALL of the pullout and push back axial force will be handled by this bearing only (as it should be). A sleeve between the inner race of the front and rear bearings would lock the axial position of the spindle shaft. the rear bearing outer race should not be constrained at all, instead it should be able to axialy float, to allow for thermal expansion. Perhaps add a second bearing to help support any torque loading that makes it through the front bearings. Finally if you can find the 30/8 bearing with metal shields , and you see that you have no debris build up between the pulley and bearing face, replace the rubber shield bearing, as the rubber shields does create heat.

Very interesting! Many thanks for this as I have been thinking about making a similar tiny spindle and motor for use on my Taig lathe - a toolpost grinder. You've made a very neat and simple unit, using rather cheap bearings (as spindles go) and low-cost spindle with ER collet chuck. Also the model motor and controller. And this all seems to work well! Now, since these components are way below the spec that most machine builders would even begin to consider usable, I wonder how well it's going to hold up? Motor and bearings overheating? Worn out after a few dozens of hours? How is it going? In any case I hope it is well! Wishing you good fortune in all your projects!

Enjoyed the video. You have a new subscriber. One request, would you work on your audio. It was difficult to hear/understand in you a few spots.

Very cool video.. And thanks for sharing the code..

勉強になりました。 ありがとう。 RCモーターを買ってチャレンジしてみます。

Outstanding job on both the video and the Spindle motor upgrade. Im a machinist and even i learned a thing or two on MRR.

Another way you could recut the taper in the machine is using a bore bar instead of a dermal. In your case you could probably use a 1 flute end mill as the boring bar.

Let's see it in steel, I seen on nc Website cutting titanium. But how good?

Great video brother.. (everything I say is only for small machines that aren't very ridgid.) I have always preached (HSS) High-Speed Machining, on small machines because of lack of rigidness. I loved to tweek my hobby machines. Ultimately I learned RPM and horsepower are the most important factors as in the weakest link besides the rigidity of your machine. If you want to obtain the highest material removal rate. Some key factors you did not cover in your video that I learned over years of tinkering on my small machines. Number of flutes on your end mill. Going from a 1 flute to a 4 you have essentially quadrupled your RPM without having to modify your motor. Also, the more flutes your cuter has the less deflection the tool will have. I'm not sure, but if you did your difection test with a endmill with more flutes, you might have less deflection then the 1 flute unless the spindle/machine is already at its limit. Try your load test with a sold piece of carbide, this will show you what amout of deflection is in the spindle vs spindle and endmill. Sorry this is long... And i had to butcher the information to keep shorter..., But keep up the good work and don't let us "know it alls" discourage you! 👍🏾👍🏾👍🏾

Have you considered using 3 flute aluminum endmill ?

Really should use angular contact bearings for thrust load.

Cool project. Did you think about replacing the complete spindle? Its now just sitting there... I like the idea of using a watersports/RC motor as spindle!

If you mentioned it in the video I must have missed it. Would you be willing to disclose where you had the tool post adapter made and how much you paid for it. I would be inclined to try to build one of these myself but the idea of trying to make the precise taper to fit the pocket and sees spindle on my imported mini lathe is a bit too daunting for me

Audio is very quiet compared to most other youtube channels i watch, might want to pump it up for next time.

Wow after watching this, my diy cnc is 2~3x more capable than this ☺️ thats kinda neat, always wanted a pocketNC though

Nice video, one thing I can’t understand is why people aren’t using high helix 3 flute aluminium end mills in this space there so much better for larger DOC. Keep making these videos make I like your information

Great stuff. Thank you for sharing. I want to point out that you did not really speed the spindle, but replaced it with a new, stiffer spindle with less stickout. Apples to apples, you would have to redo the deflection tests with the new spindle...

Great job, can you check your editing software a s even at full volume I struggled to here properly.

O estilo de edição 3 Blue, 1 Brown não passa despercebido. Fiquei muito surpreso ao ver um canal com 371 inscritos fazendo gráficos tão informativos e precisos quanto esses. Eu nem fintei o vídeo e já estou deixando um comentário sobre como ele é bom. Há realmente uma arte em fazer um vídeo conciso, ao mesmo tempo em que comprime o máximo de informações possível, tornando os infográficos e outros visuais precisos e fáceis de digerir. Estou ansioso para ver mais conteúdo!! Também não pude deixar de notar que não faço a menor ideia de como se faz o G-code, ou o caminho para corte em uma CNC de 5 eixos, já que o que mais se vê na internet são CNCs de 3 eixos apenas, você tem algum vídeo mostrando qual programa você usa e como funciona a pocket NC?

The only things I noticed in this that didn't quite make sense to me was: 1) you have a 30k rpm motor, but you said the dual row bearing is only rated to 25k rpm? 2) I've not seen belts used at this speed before. I know it depends on the pulley size but even then it's questionable how long it may last running at 30k rpm.... 3) it might be worth putting some threadlocker if you haven't already on the screw acting as a tensioner for the belt and the screw pulling the bearings together to reduce any backlash. I have a feeling after some time these would work themselves loose and wouldn't be very desirable 😅

The chart at 1:52 has RPM at 10,000 for each column...

Curious how you get the pocket nc motor to not run. Do you simply program a 0 rpm spindle speed and run the program normally? Then do you assume manual control by turning your new spindle on and off yourself? I assume this limits you to only 1 tool per program since tools must be probed before running the g code on the pocket NC? Very interesting.

What is that band that breaks off the M-vac engine at start up?

When you pressed it together, you pressed the pressing loads through the bearings balls and races that’s not how you do it. You need to rethink your design, so that bearings can be pressed properly. Otherwise nice design!

Super awesome video! Keep it up 👍🏼

Nice job!

i looked at the pocket nc a LONG time , but for several reasons (mainly value of the machine) but also software , layout, no touch probe, i decidet to NOT get one, instead i commited to building a diy 5 axis cnc, CAD is 95% done, uts cheaper and its (at least in cad simulation) way stiffer (also 1,5 kw vs 0.2 kw spindle ....

Very cool. However, I'm very interested in the fiber laser that can laze tool steel away! Not typically something a hobbyist has access to.

Dang that's impressive!

can i get the link for the belt?

how to you know the loads ?

Please normalise your audio, then maximise it to -1dB peak. At the moment this video sounds like it's using less than half of the available amplitude, that not only looses fidelity, but pisses everyone off who cranks their amp up to 11 just to hear what you're saying, then casually unpauses their music and kills their pet cat who happened to be nearby the 1200W 18" sub at the time, bringing a new meaning to: subbed.

dont used ground in fusion its bad practice. use as built joint instead

Why not simply use a 2-flute or 4-flute milling cutter instead of a single-flute one?
