2.2kW Chinese Spindle & HY VFD Setup/Testing

[@Kosh42EFG]

Did you check spindle case to ground?

[@ChristophLehner]

Yeah, it has continuity between the spindle body and earth pin on the connector. One benefit of not buying the cheapest spindle you could find

[@Kosh42EFG]

And brave. I unplugged the spindle cable when turning on the start to check the pump.

[@Kosh42EFG]

@@ChristophLehner My Gpenny was the same, already done right. Nice video as always.

[@OleBjerkholt]

😁That chamfer tool was like a bullet in the aluminium. Great content!

[@DodgyBrothersEngineering]

I have had my fair share of whoopsies, but yes that shot into the aluminum really quick.

[@gaiustacitus4242]

I watched this video again and thought I'd share my first experience with friction welding a 1.000 inch diameter end mill with 6061 aluminum. The end mill was turning at 3,000 RPM, and instead of feeding down into the part 0.100" the spindle attempted to plunge the end mill all the way through a 1.5" thick bar. A blog of molten aluminum was thrown out and it landed on my throat. Just one of the adventures in machining. Good luck in the many adventures ahead of you, and stay safe. p.s. - I tried to salvage the end mill. While I was able to extract the end mill from the aluminum bar, I could not remove the aluminum from the surface of the tool steel.

[@DodgyBrothersEngineering]

In my early attempts to machine aluminum I tried it without any cooling, and once that cutter is clogged it is virtually impossible to get off and still be able to use the cutter. I rarely clog one these days. Fortunately my cutters cost me like $1 each, so it is no big loss, just frustrating.

[@toddmolloy311]

Gotta get it while it's still hot or send it through an acid bath to strip 6061 off the carbide tool.

[@bjondersson]

To remove the aluminum from the endmill put it in sodium hydroxide, a.k.a. caustic soda, lye, drain cleaner. If there’s just a bit of aluminum 15 minutes may be enough. I had to soak my fully clogged endmill over night.

[@waqasaslam360]

Some humble suggestions for better surface finish: The tool length has to be as short as possible. Finish pass should not remove more than 0.2mm of material. Lower the RPM . (21000 rpm is way too high , i guess under 10000rpm would be good)

[@InheritanceMachining]

"oh no... I fucked up... I fucked up" comedy gold 😂 This whole video had me grinning. Well worth the wait while you got it all sorted out. Side note, that's the same VFD I installed on my lathe. I think you'll like it in the long term

[@ChristophLehner]

After seeing you engraving the wallet manually i think it's time for a cnc 😅 (don't do it)

[@InheritanceMachining]

@@ChristophLehner I don't know... that was another project that would have been a 5 minute job as opposed to 2 hours! 😉

[@DodgyBrothersEngineering]

@@InheritanceMachining don't know about you but I can any 5 minute job into a 2 hour one. I'm talented like that...

[@dr_regularlove]

This is exactly the part of my build I'm on. One thing I did was lengthen the water pump power cable so I could move my reservoir farther from the electronics, just in case of splashing, and I'm glad I did! Anyways love your vids, and hoping to join the Cutting ranks with you soon!

Change to a larger soldingering tip or you need a more powerfull soldering iron. It should only take secounds to heat up the wire and connector so you dont get the heat creep up the wire and melt the isoltation.

[@xaty1808]

Thank you, very nice to see your adventures. Last year i build a 3D printed/wooden CNC with a Dremel 😅 from recycled and/or cheap parts. I learned a lot from it and your video's convinced me to start with a print NC in the future.

[@anmafab]

You're deep down the rabbit hole now man! I'm still curious if you'll go back to the CNC router inception project for the furnace?

[@ChristophLehner]

Haha the furnace will come, i promise 😅

Mount that on a nice polished walnut base, with a glass dome over it, and the "Artist's" name on a brass plate... worth a fortune! 🥴

[@gaiustacitus4242]

You've probably learned by now that down-cut bits are only to be used for finish cuts. Most of the videos produced by hobbyists show using a single bit for the entire milling operation, but its best to use an up-cut bit for roughing and leave 0.005" to 0.010" for cleanup using the down-cut bit.

[@DodgyBrothersEngineering]

Or use a down cut bit and reverse the direction of travel. Make your final cuts in the opposite direction.

[@gaiustacitus4242]

@@DodgyBrothersEngineering I should have qualified my statement that it applies when machining metal. Conventional milling of metal produces inferior surface finishes, as does roughing and finishing using the same cutting tool. Conventional milling sometimes causes tear out when milling wood (mainly when the cutting tool becomes dull). Down cut bits don't generally work well for machining metal as the chips tend to pack up and cause the cutting tools to break. This is an opinion based on running a machine shop with more than 360,000 spindle hours per year for more than a decade. Tool life was an important factor in the cost of operations and quality of finished goods.

[@DodgyBrothersEngineering]

@@gaiustacitus4242 typically none of my bits live long enough to wear out, but I am currently shooting a video where I am chewing through cheap Chinese cutters like butter. Changing direction of rotation did get me some more tool life, but they simply do not like cutting steel plate. Especially after I work hardened it without thinking. FYI I am the novice that you speak of that uses the same cutter for everything, but I far from claim to be an expert, because I am far from being one. So I appreciate the advice you gave. I need to see if I can find a source of cheap up cut bits.

[@DanGoodchild]

Excalibur… 🤣 Brilliant!

[@theorangebaron1595]

Great video, definitely interested in these Chinese spindle and vfd combos, looks like some great value.

[@garethevans9789]

Now that's a surveyor! 👌

[@xyzspec82]

We all have done a plunge like that (I believe) ✅ Check if spindle bearings are in good shape before starting the spindle again (don't ask me why lol) I bet you'll be chasing better surface finish for some time as I did (in fact I still am...) A DIY CNC is never finished 🤓😅 Love your channel bruh 🙌🏻💥

[@ChristophLehner]

Thanks man!! I should indeed check the bearings, thanks for the tip. Before i am.chasing surface finish i probably should figure out good f&s and not f up the z offset 😅 But nyCNC has a good video about surface finish

[@xyzspec82]

Probably the PRINTNC base being made out of wood and not supported all the way is your biggest enemy. That's the main reason why I made my concrete base 😉

[@ChristophLehner]

@@xyzspec82 do you mean the wasteboard? Yeah there is quite some.flex.to.it, even with 40mm MDF

@XYZ Spec ain't that the truth. Had mine partially finished for about 7 years now.

@10:59 More like ExChamfiBurr 🤣 Did you perhaps mark the Bottom of the Part in the CAM as a reference point instead of the Top or how did you manage to pull off that stunt?

[@ChristophLehner]

Tbh, i have no idea, somehow the tool lenght offset measurement didnt work out, or i did a reset in between, which is probably what happend 😅

[@JohnOCFII]

Great overview. To see you do the wiring, complete with the hand-drawn wiring diagram seems less scary that some of the others I’ve seen.

[@juansalgado6212]

What is the ModBus on the GRBLHal board? Is your board the teensy bob? If so where are you connecting the RS485 on the board? Is it on 0-10v and G ? thanks

[@TecnoLAZ]

Amazing, i buy one equal. Its amazing spindle

[@DogSerious]

You should have recalibrated the new bit.

[@Aaarbakke]

Haha, great stuff! Keep it up:D

[@demetriusmichael]

Did I misunderstand your setup? When your hot spindle turns off, you stop the water pump? When your spindle turns on for the first time, then your water pump starts priming while you’re cutting? Love this either way.

[@ChristophLehner]

Yeah, as soon as the VFD starts turning the spindle, the waterpump.comea on via a relay controlled by the vfd

[@demetriusmichael]

@@ChristophLehner ah why not have it run all the time instead of just when you’re cutting?

Hello, I have a Huanyang vfd and 2.2kw spindle 220 volts. I did not reset my vfd when I put in the settings from several videos. It worked except it would only go to 208 hertz. I reset it and now it goes to 400 hertz but the potentiometer does not work. Is there a setting I can change to fix it. TIA

[@mciarlillo1309]

How has this combo been holding up? I ended up purchasing a RATTMMOTOR 2.2Kw spindle and Huanyang VFD as well but I haven't gotten around to installing them yet. The RATTMMOTOR seems to have hit or miss reviews so I'm curious how yours has been doing 1.5 years in?

[@ChristophLehner]

It's still going strong. The bearings are a bit noise but tbh, after 4 weeks I already thought they gonna fail since the sound changed. But it still holds up, and has had a lot of use. Can't say anything bad

[@trezos2822]

New to this stuff and im eager to know what was the cause behind the bit getting stuck? Was it the machine path being a bit too eager to get straight into chamfering the aluminium, and not having a slow enough z axis approach into the aluminium for the rpm it was set at?

[@ChristophLehner]

I measured the z offset with the 6mm.flute, then changed to the vbit, measured the z offset with this tool, but then i think i drove into an endstop, had the reset the controller and the measured z.offset was gone. So the z0 was not.offset and was therefore somewhere in the middle.of the part. But this all happend so quickly 😅

@@ChristophLehner At least you have small enough fuses to blow. Most of my machining adventures have occurred with 440V 3-phase motors in the 2HP to 25HP range, and the breakers never tripped. It always made me question why machine tool designers locate the emergency stop switch where you have to risk your life to hit it.

How well has the VFD & Spindle held up 9 months later?

the spindle nut did seize up, but i managed to rescue the threads, but it's a matter of time, before the threads on the spindle are not usable. i already have a replacement spinlde for 150€. but for whats its worth i'd still buy it, since it is so much cheaper than an atc spindle

thats really good to hear that its holding up relatively well. ive been going back and forth for my first CNC on the spindle (and everything else, lol). It was between the Huanyang 1.5Kw + VFD or something like Stepcraft MM-1000 DI and possibly ATC in the future. @@ChristophLehner
