I "fixed" this cheap Chinese tool

- I was sick of manual tool changes on my DIY CNC Milling machine, so I bought this cheap BT30 spindle with automatic tool change capability from AliExpress on impulse. It wasn't long before I started to regret it. Watch me stumble my way through two (2) attempts at taper grinding, and finally settle for a barbaric final solution. If it wasn't clear from the video, you should NOT buy this spindle.

The cross-contamination with IDAT scares me lots.
Same! I was like wait a second I know that voice...*Ralphy voice* I'm scared
They're about to change the channel name to Boy boy boy I think.

Can confidently say I have no idea what’s going on for most of this, but it’s fascinating to see the complexity behind these machines and you’re a great story teller, so you’ve got me hooked
I get everything and i'm impressed by what can be done with so little.
Didn't even know they sold TC spindles for that cheap
@@angrydragonslayer i didnt understand a thing but loved the video
@@scottessery100 I heard "grub screw" and I instantly knew he was talking about my ex. It really is a small world.
did you come here from i did a thing?
@@realcarguyrighthere nah, TH-cam algorithm.
Just recently found I did a thing as well
This is really well done. I love the dark aesthetic. It compliments the depressing undertones that reflect the reality of every DIY project we chose to curse our own lives with.
The boy boy cameo was awesome
It's funny because boy boy is actually a tankie
AUSTRAILIANS HAVE GREAT SENSE OF HUMOR, THIS CHANNEL GONNA DO GREAT
GREETINGS FROM DOWN-UNDER, MATE
@@NoEngineerHere SOMETHING SOMETHING VB SOMETHING SOMETHING
This channel is going to be big! Keep it up. Love the content!
Very refreshing to see someone on here being persistent with using their brain. There are a lot of people on youtube buying expensive stuff to ruin it. Doing the opposite is not only way harder (leaving the money aspect aside) but is also so much more satisfying to watch. And the humour you fabricate out of self-criticism is gold. Thank you!
Don't take this as a criticism, but I would like to give you some tips for your griding setup. A spindle taper is not that difficult to grind, but never use feeds other than single axis. This adds up to the machine's errors and backlash, and very few CNC milling machines are precise enough to properly perform grinding to the precision required for BT30 using feeds in multiple axes. Typically, the attachment with its own feed is placed on the table, ensuring that it is perfectly parallel to the wall of the taper, but if you prefer to use the machine feed, you need to mount the spindle at an angle and the grinder vertically. You should move only Z-axis. Use a dye to check your progress and correct the angle if the top or bottom stops making a contact. Also make sure you're not pushing the grinder away, make empty feeds every few passes until the sparks disappear and the spindle is quiet, and then continue.
As for the bearings in Chinese spindles, they are terrible. It's best to buy the first one you find from Japan/USA/Europe. If you have a lathe, you can easily make a better housing out of a piece of steel or at least aluminum. I feel like you know how to do it.
Manual spindle scraping is only carried out on quills and mounting surfaces (sometimes on bearings in huge machines), I do not recommend it for DIY, it took me several years to learn it at a basic level, and here you need a master level 😉
Actually most spinde repairs are done with driving two axis simultaneously. Real cnc machines are accurate and repeatable enough to manage the operation. Not the diy hobby machines but industrial ones, like Mori, Emco, Mazak, Okuma and many others. Making parts within couple of thousands of millimeters days on end, grinding a fresh taper is easy.
The first time around it did a fantastic job with interpolation, so I just stuck with it. I was tossing up a bunch of approaches before I jumped in, and your method definitely crossed my mind! I have a few thk linear motion units (combined bearing and ballscrew with a motor mount) kicking around, which I think I'll make use of when (if) I get around to regrinding this spindle.
I think if I ever go to that trouble though, I'll pick up some beefier bearings, and probably make up a new housing. And the headstock needs work. So don't hold your breath for pt 2 any time soon 😁 I'm pretty deep into the lathe you would've seen in the video, which involves building a new spindle, saddle, tailstock, + maybe adding some CNC lite™ features.
It never ends (thank goodness) 📈📈📈
And thank you for the info! I've always got a lot to learn.
tbh you could probably throw some bar stock in your lathe, add a couple of skf bearings, and make a better block than you'd have trying to salvage this.
@@MJPilote Fadals certainly aren't!
videos like this are few and far between, no small floating video in the corner of my screen while i continue to play a game. no phone. no idle face stuffing. house could be burning but only this has my attention and it flies by in a snap. thanks for the video ❤
Midnight upload, not an engineer but a fellow degenerate, thank you
I really enjoy these videos! The humor, the accidental education, the fantastic music
Can't properly express how simultaneously delightful and terrifying it is to see you, Alex and Alexa together....
Already can't wait for the next video and possibly some more crossovers with Alex and Alexa. Keep up the good work mate!
Dubious setups? Stressful long-sleeves in the machine shop? Unexpected Alexa??!! Damn, this channel keeps getting better!
Edit: Of course you got IDAT in as well... The Aussie family expands!
"Ever done something you knew you'd regret"
hahahaha
and yes, almost always it's buying something from China 🤣
I work in a Company that build SK and HSK Spindels and the Tool Holders here in Germany. The fact that you could get that runout into this specs is impressive. Seems like you are not forsaken and the Gods smiled upon your effort :)
Wait a minute! You grinded the spindle by keeping it straight and offsetting the grinder by machine table movement in Z+X (or Z+Y) !? Holy moly!
I guess just another way to learn that hobby-grade (and for the matter any) stepper/servo based system is not precise enough for such an operation.
2 tips:
- Align it by tilting the head of the machine/spindle in the precise angle of the taper (the hardest part) so only Z-axis ever moves during the grinding process. Indicator is a must here!
- Use much bigger grinding disk/stone than you used the first time! Ideal is 9/10 of the narrow side of the taper.
Good luck!
I did a near identical process to my cheap bt30 spindle cartridge. I rigged up a high speed grinder vertically and had the spindle move up and down at the taper angle. I also had to manually grind down high spots to ease the process. It's probably more common than we think.
It breaks my heart to hear an Australian pronounce Zed as Zee.
I did a things chaos, this old tonys sneaky video text and editing style. I love how you've pulled inspiration from other channels and created something of your own. Im so glad i subscribed in the early days of your channel!
No such thing as original content!
Loving the smoothest of jazz
I don't know how i missed your videos earlier. Fantastic job. First of all your cnc is beautiful. Secondly you videos are really well made. Finally third is the content which is exactly the style I like. So i couldn't resist and had to subscribe. Hope to see you shine here :)
I have one of those 7" mini lathes, and with upgraded bearings the headstock is remarkably good for what you pay for them. It's MT3 with a flange, but that is easy enough to get rid of.
Keep it up man, I really hope that you'll have a lot of success with this channel.
You came outta no where and made absolute banger content bro, I look forward to seeing more
Amazing! I laughed so hard and the cameo!! So excited to see what's next, but no pressure you take your time and figure out your balance
This is why I bought a proper lathe and milling machine many years ago. Hopefully they will be a help when I start on my DIY cnc router.
This guy is not making videos. He's taking us into great journeys, with highs and lows. He's distilling what make the essence of a maker. Pain, and sometime, Joy, at last.
Just an idea, have you seen how mechanic's use a paste for grinding valves to get a clean fit "Valve Grinding Paste 100g" might be easier than doing the tapper by hand.
This needs precision over multiple parts, not just between two paired parts.
@@volentimeh - Obviously, he needs two more cheap spindles to implement the 3 thingy method of metrology generation.
I love the subtle humor in these videos :D
Also was that a small hint to a "I did a thing" collab at the end there?
I hope so
This is incredible. Australia is just the place for great YT channels.
Great video. Envious of your machine for sure. As for the arc pauses, try setting G64 at the beginning of your G code. It’s constant velocity mode and will smooth out arc movements, should be a way to set tolerances on the smoothing as well
Thanks for the tip! Will give it a try
1:02 I enjoy how the subtitles say something completely different to what you're actually saying
I have to complement your voice-overs. Though you are - idk what the word is, unprofessional, nervous sounding? - you are confidently so. During my own short burst of youtube inspiration, I didn't even have the balls to finish editing when I sounded so shit. This is a testament to your inability to feel public humiliation: the most important skill for an aspiring content creator.
Good lord, there's hitting the ground running, then there's this channel. Did not expect the IDAT crossover lmao
Awesome content mate, can't wait to see more!
The Boyboy cameo was quite thee surprise, loving the content, keep it up
That’s awesome !
I have a cheap Chinese tool & cutter grinder that I bought used , and I spent probably 60 hours in hand-scraping the table flat, all the ways straight, rail beds flat, and adding an system . After all that effort, it’s straight, but still a terrible grinder .
But hey, it’s the only thing small enough to fit in my shop.
The production of this video was perfect. The way you speak into the camera with your mannerisms, and the background music choice is dialed! Outtakes too!
Some turds can be polished 😉
Looking forward to that IDAT collab.
fancy seeing u here
I wanted this as the title so badly
Very interesting!
Love seeing CNC stuff!!
Keep em coming!!!!
I liked your cable management. it looks tidy. 👍😉
I found your channel via Inheritance Machining channel.
This is sort-of how I imagine my forays into owning a workshop will be, if I ever get to fulfilling my age-long dream of actually getting started at one...
It's not something that happens overnight, so you should start now.
我也想，可惜中国大多数人没有独栋房和车库
Oof I had the exact same ringing/resonance when cutting in the Y-direction on my vmc build just like you had cutting that arc. Ended up discovering that I had a few thou backlash in my X-axis. The BK ball screw block I had used deep groove bearings without preload and allowed quite a bit of axial play - swapped these out with angular contact + shim washer and has been cutting like butter since.
Yeah I think it's a combination of a bunch of things. That endmill was well used as well. Have since been playing around with some brand new roughing endmills and it's playing a lot nicer!
These are great videos, so please keep them coming. Not sure if others mentioned this but, as for that taper, the nice thing about them is that you don't really need the entire taper to make contact. I have seen Morse taper tools spin, causing galling inside that a taper ream couldn't fix, so most folks will just run a boring bar up in there and remove a clean and consistent groove where the galling was. As long as you still have concentricity and an adequate amount of contact, you will be just fine. Thanks for the great content!!!
I love that there's like 4 Aussie boys who get together do crime, make crafts and film TH-cam ❤
Good choice of background music!
I'm also impressed you actually gave credit in the summary.
Lovely, just what the doctor ordered, another fun and educational masterpiece, thanks mate ❤
A very cute video! Thank you for keeping the background music at a proper level so that I could hear your voice as you spoke.
7:25 , now i know why i found you in the first place, ALL HAIL THE ALGORYTHM!!!
the irony... the humor... I'm hooked.
Came here for some sweet sounds... was not disappointed 😊 keep it up man!
I've watched all of your videos in one go and I love them. Welcome to the hell of my subscription feed
Petition to make a film out of this amazing story.
Buy a metal throat tube for your Kingroon 3D printer... The hotend has a design issue where it has a PTFE tube in the tip of the throat tube that melts way below the point that PTFE should. It also has a cavity at the top that filament likes to use as storage space and that causes jams.
I was very near buying a whole new toolhead for my KP3s before I found out that the throat tube was the issue
37K subs and only on your third video! Phenomenal success and well deserved. I had your first vid saved for later to watch and didn't realize this was the same channel. Gotta go back and watch the other two.
Thankyou thankyou! Still can't really believe it.
@@NoEngineerHere Clearly you're on to a fantastic formula. I always tell people to show a lot in a single video and keep it simple. I need to follow my own advice. Have you ever worked on another channel?
First time if you can believe it! But I have watched a whoooole lot of good TH-cam.
@@NoEngineerHere Truly amazing! You definitely deserve the views. You have put in a ton of work here. I've been at this for years and I need to get on your level. Hopefully my next big series will be. ;)
Are we gonna get a lathe build video in the future?
Also thank you for muting the cutting sounds with sped up video!
Your comedic timing is impeccable.
...while being very good engineer (with all the related OCDs that all the good ones have)
That manual translation bit is some of the funniest shit I've watched in a long time, lmao. Great stuff man, I'm excited to see your future projects.
I have that exact same lathe you teased at the end! I am looking forward to seeing what you do with it so I can improve mine.
If you've got any info on it I appreciate it! Haven't managed to even figure out the model haha
@@NoEngineerHere Sorry for the long wait. I didn't get a notification when you left the comment. I will be sending you an email with all of the information I was able to find. Far too much to type out here. Love the videos, keep up the good work.
The vibrations is caused by slack in X
Two places it can be, the ballscrew (if you got those cheap ones, the balls are not made from proper steel and hardened properly, the screw itself is rolled and will last enough for hobby) or the guide/rails/tracks. Very good video!! It really shows the issues we face when buying cheap parts (am toolmaker, but also play with my own DIY for fun)
in the end you were doing your friend a favour in learning his chinese as translating would be good practice
The surprise Aleksa lmao I noticed Mao first and looked over and my brain rebooted
Love your videos. Keep it up. You know, messing things up and repairing them and repairing them and messing them up but finally getting it in the end. Cheers.
I enjoy your development of the story. Well done, good measure.
that text spinning around the spindle made me subscribe
Excellent video. You deserve more subscribers!!
Wonderful humor in this. Good work problem solving, can definitely relate to the pain of having to figure this shit out.
Guy from r/hobbycnc that asked for this spindle, been waiting for this video, now I know this spindle is garbage. Thank You.
Sorry it took me so long to answer hahaha!
Youve got amazing patience and tenacity. I'd have just binned it. Great movie.
I loved your dry humor and subscribed, thank you for the entertainment.
My second favorite Aussie TH-camr. Sorry Alexi
I love to see you've mixed in with boy boy and ididathing
thanks to you im connecting with my mechanic brother, by sending him your videos and talking about this stuff
I would recommend you check and adjust the bearing endplay(and may e sideplay too) on both your lathe and your mill spindle.
You're flatmates with boy_boy - that's amazing!
Also manually 'lapping' the taper with a die grinder is hilarious
New subscriber! You look like my nephew and you you have the same crazy sense of humor. The you the most important quality of a good machinist, TH-camr, bonsai artist (whatever) and that's persistence. Keep up the good work, thanks and Happy New Year.
I like your moxy, kid. You don’t give up. You don’t the heaviest things weigh you down. Makes for a great artificer.
I have a traditional home machine shop, which I call my $150.00 machine shop because I have six lathe I’ve accumulated over the years, 5 of which I paid $150, each, at the time and the last one I paid $350 for because it’s what’s called a 3 in one lathe milling machine. Though each had its set of problems, for the price I paid for them, all. It paid out in the end as precision machines after little work done.I now have a precision home workshop.
If I could do it in a similar way you’re doing it, I know you could do it in a similar way I did. Keep up the good work, makes for a fine channel with great content.
a guy who does things sent me here
I’m here from “I did a thing”. Great work on that video mate. Looking forward to watching your vids too.
Pretty cool one thing you could try is using a boring bar to turn the spindle in place.
Excellent, good scarscam with a lot of noble tries, and still keep your sanity, your CNC will never look the same again. Well, for today anyways! Awesome channel, keep it up!
Dude this guy is like Australian This Old Tony that knows both parts of BoyBoy. Definitely gonna keep checking him out
the text editing on this video is beautiful
Good stuff dude, came here from How To Basic’s slightly less intelligent cousin who built that Diana killing Beyblade. Keep it up
We all hope your producing more of these fantastic videos........WE WANT MORE PLEASE!!!!
For translating manuals you know you can just scan the whole thing in to a PDF and then feed it to one of the online translators. Or feed each image manually as needed.
I could do that, but then Aleksa would never progress in his character arc
I have found it much easier to just feed my translator once a day. then ask them to translate something for me. They don’t complain about being hungry as much.
You’re enjoyable . Refreshing to watch
I don't understand half the things being said but I love it! all the best xx
Yeah! New awesome video, and Aleksa. And Alex. Sweet.
First time ever the "like and subscribe" actually made me do the ol' clicky-click.
Now please do more collabs with your beyblade buddy!
As someone who is just now going to a trade college for machining, I love that I can understand most of what you're talking about!
Love the content and I can't wait to see more!
I'm not an engineer either! and, I watched all your videos. Awesome job bro! 🤟
Loving the vids. Don't let the pressure mill away at your soul ;)
This feels like mechanical Asmr, great video ngl
Probably will never read this. But if your in Sydney I'm happy to help with the lathe refurb. Got the gear and some idea. 😂 keen for more videos love the production
I can't lie this guy is hilarious - very entertaining to watch
I will comment on every one of your videos so the algorithm loves you as much as I do
I love you
you may not be an engineer but your a master rigger
Came here from I Did a thing. Interesting videos, hope to see more soon
mounting it on acrylic is tickling the dragons tail
i don't think i can approve of that
but it sure looks cool
