Review of Jianken Chinese 2.5KW ATC spindle, testing the spindle limits, vibration test, pushing it to the limits of the spindle and vfd. This is a second review after using this spindle for over a year.
usually my videos are long so in this one I tried to be as brief as I could, so if I missed something please let me know 😉
I was looking for a reliable manufacturer of cnc spindles and it looks like i found one.
I can honestly say that after a year of using it, it is the best Chinese spindle on the market, with really good support behind.
also they provide very high quality tool holders from company in Taiwan: Parfaite
Spindle tool holder which i got is a ISO25 taper and ER20 collet.
Spindle price was 1450usd.
spindle manufacturer website: www.jian-ken.com
contact email: jk@jian-ken.com
ceramic ballbearing manufacturer: www.coorstek.com
coorstek cool video about ball bearings:
if you want to know more, very interesting research paper on ceramic bearings:
excellent paper on spindle vibrations:
Piece of aluminium i was destroying on this video was:
6061 aluminium extrusion – 44mm x 44mm x 73mm
endmill:
rebranded chinese 3 flute aluminium end mill 10 x 30 x 75 x 10
cnc machine:
home made out of granite, making off videos:
That amount of chips I was doing in under one hour at work with one of my two Starag Heckrerts😁 but they had each 24k spindles with roughly 80kw😁 i realy like your videos.
It’s um… spectacular!
Do you have your vid settings available , with the settings wafer gave me my 3.2kw version of this spindle stalls out at 12000 rpm with a 0.5mm woc and 5mm doc on a 12mm 3f endmill.
Iam curious and wonder how well this spindle has held up. I am about ready to hit the buy button but thought I would ask first
Hi Fox love your work what VFD are you using for this spindle
Now I need an ATC, too! Have you tested boring holes? What is the torque?
Hi piotr, thanks for sharing. I would like to know if you always had a fast responce from wafer ? I ordered my spindle 2 weeks ago and haven't got any news in spite of my email. Maybe they are in holiday
Im building a cnc lathe at the moment and after that I want to build a very solid 5xis. I think this spindle might be the one.
Your machine is a beast
Try it with way more feed
End mills are usually rated for round about 0.05mm per tooth (depending on size and material) often more.
If i heard it correct you used 24k rpm and 1000mm/ mim which results in around 0.014 mm per tooth
If it isnt the chinesiest of sellers they normally provide speed and feed data
Endmills wont break that fast😁
About the 8mm cut, that one should be within spec of the spindle around 10.5 A at 230V (i guess) equals to about 2.4kW…
Appart from that nice video👌
really nice guy, and helped me alot to choose a good spindle. Have left an abo!
Hi Peter, Can you tell me what inverter you use with the spindle, please?
I contacted them, If we say we come from you they offer only the water pump = 15 USD…. So I wouldn't say it's pretty big discount !!
How a spindle like this will perform cutting steel?
nevermind i found the answer in a comment below, thanks for sharing!
Any reason you went with the 2 pole vs the 4 pole spindle?
I've emailed Jianken half a dozen of times from different emails, they do not respond.
Hey buddy i have posted various comments on how to contact u…….Could u kindly share your email or any other source of contact plzzzzz
Hi wonder if you can help, building a milling machine and wonder if the torque is sacrificed at lower speeds
Great video! What RPM are you running this on?
Would be interesting to see how it does in steel…
Mill Tip size ?
Hello, I also have a jgl spindle from jianken, could you tell me what frequency inverter you have?
Thanks for posting Piotr. I had to have a chuckle when you mentioned the discount as I bought one of these spindles about a year ago and I mentioned your channel so they gave me a US$26 discount. No big deal though but thanks for posting, it gives me confidence in my machine.
I'm not even sure how many times I've watched this video. It's so satisfying to watch.
Son, do your tests on steel. Then you proof something. Aluminium is much softer than steel. If your motor (and end mill) performs well on steel, it will most certainly perform well on aluminium. I watched a few of your videos and liked it. I'm busy with a CNC milling machine with a two meter long bed and will most certainly look at things you mention in your videos.
how much RPM did you use for testing those cuts?
Thanks for a fantastic video. Could you please share som info about the iso 25 toolholders. The collet nut looks special
what is the end mil diameter ?
Nice video and review want to buy that spindle what vfd you are using sir?
Hi,
if you apply force to the tip of the end mill, how much is the movement in reference to the table?
Thanks
Please just call it a Taiwanese spindle. You're just causing confusion. Yes, Taiwan is the R.O.C, but nobody calls it this. Made in Taiwan is Made in Taiwan.
so satisfying to watch the chips fly when you slice at those speeds like going through butter! Thanks for the inspiration:)
seria muy muy interesante si nos contaras como funciona el sistema neumatico para el cambio de herramienta
здорово! 10мм!!!!
Your camera was a perfect angle to eat some chips.
Holy fucking shit i felt the spindle gona pop up and blow everything . That is spindle is good for drilling mars
the rigidity of your machine is really demonstrated here, even more than the spindles ability to remove material
Nice spindle! I have a project of my own which would mostly involve drilling. Does it have enough low end torque (around 2500rpm) to drill 6 to 8mm holes into 6063 aluminum?
you an put your VFD to start automatically yous selenoid and then air would fill the spindle
Simply connect a second relay to your 24v relay from the VFD. you can get relay boards for less than 1 $ from China.
could you make a video explaining your more about what is necessary to run such an amazing spindle: like air quality/ amount. Why did you choose the 100mm version and not the 80mm? What is the approximate price of the spindle
I'm looking to buy a ShopSabre 23 and keep looking for a mid range spindle to replace their Porter cable router. Their upgraded option is a $3,200 Italian spindle and I'm just a hobbyist. I have never done cnc before so I was wondering if I can any spindle on any machine as long as power, HP, and size/weight work on the machine? The ShopSabre is basically a commercial machine, it can hold hundreds of pounds haha.
What I don't know is how the ATC/VFD works with the software (vcarve pro). I understand you need the correct sized mount for the spindle but will the software just adjust the VFD? The ATC I assume is as simple as setting a destination point per bit but I don't understand what you need to disengage the bit and add another… would that also be in Vcarve pro?
Here is the machine I'm looking at: https://www.shopsabre.com/cnc/router/shopsabre-23/#4 specs are below if that helps in anyways.
if you can give any insight on this I'd appreciate it very much.
Thank you!
David~
That looks very promising. Ive been in contact with Wafer to get some answers and Im hanging on the purchase button 🙂
It all comes down the price and the amount of accesories. how did you connect the air return to get the spindle to turn freely direct after a tool change?
cheers
nice job! 🙂 …Have you tried to cut stainless steel? how were the results? 🙂
I bought a 2.2kW water cooled spindle from this supplier after seeing your original video, I'm glad to see it is still working great and something you love after a year. I haven't finished my machine just yet (wiring it atm) but I can say that I can not measure any runout at all on my spindle (non ATC version) and it runs smoothly on a Teco VFD! (Teco L510 also sold by RS Components 174-8218 incase you're interested) I'll be happy if I can run nearly that fast on my machine.
Can you tell us what frequency VFD are you using? thanks.
You could have made this video without sound. The constant smile on your face is proof enough for me. Great video and very nice machine 🙂
Very nice machine. The spindle looks really good and powerfull at that price point.
Very nice setup. I was impressed by the lack of chatter on the 10mm x8mm cut. Your machine is more rigid than mine, or is it the spindle? If you haven't already, check out making an air mister with a pressurized house water filter to hold the coolant. Works wonders compared to dry cutting, is cheap, and not messy like full coolant.
Piotr: If I remember correctly, you mentioned in your first review that you were going to try using inexpensive toolholders/collets. Did that work out for you, or did you find it necessary to upgrade? Also, your spindle's stated rated current is 6.6 Amps, yet it seems to be working fine at up to 10 Amps! Did you receive any performance and/or setup information for it from the manufacturer?
Did you check that your spindle was really running at 24,000 RPM? Your setup video for the VFD (4 pole configured for a 2 pole motor) suggests that it might be running at 12,000 RPM.
