ATC 2.5KW testing the spindle limits - THE BEST Chinese spindle, second review after over a year.
Рет қаралды 64,665
4 жыл бұрынReview 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 www.parfaite.com.tw
Spindle tool holder which i got is a ISO25 taper and ER20 collet.
Spindle price was 1450usd.

I bought this same spindle immediately after your first video about it, and I agree completely. It is absolutely amazing. The only thing I wish I did different if I were to do it again is buy the 110mm BT30 version instead. So much more tooling is available in the BT30 than in iso25. Literally all I can find in iso25 is er20 coldest. They do the job but I would have loved the options.

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...

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.

Beautiful! Very interesting to see these empirical tests. I would be curious what the current draw would be with a fresh endmill. Kennametal's engineering calculator suggests an approximate radial force of only 100N with a torque of only 0.5 Nm in the 4mm stepover, 10mm depth, 3000 mm/min feed test, with a power draw of 1360 watts. In the test we see a peak current of about 9A (at 220V?), about 2000 watts. At least in theory there should be quite a lot of headroom (you are probably right that the VFD and the tool are the limiting elements), especially if you find a zirconium nitride coated tool, but for what you are doing I doubt you would really want chips piling up that fast :). I've seen youtube videos of similar tools with upwards of 20000 watts (not a typo) put through them. So, perhaps a lot for this machine, but quite conservative in the big picture! Good to see another video, amazing what is available from China and what you can build when you have a need. Looking forward to seeing more from you!
@PiotrFoxWysocki 4 жыл бұрын
maybe 2000 watts vs 1360 watts difference is because o system efficiency. or its just for a cut. free spinning spindle takes 1.8-1.9A maximum power on a cut was 8.9A so it comes closer to 1500watts. the difference just for the cut. i guess there is lots of factors when you try to calculate it on the paper.
@CalvinoBear 4 жыл бұрын
@@PiotrFoxWysocki for sure, I was mostly trying to get a frame of reference. What's most interesting to me is how little torque and force, at least in theory, is generated in such a cut. The high RPM really brings those down.

It appears that the currents shown are for the motor currents provided by the VFD (right Piotr?). If that's the case, motor power input power = motor voltage * current * 1.7321 (since it's a 3 phase motor.) Cutting power is proportional to material removal rate as well as spindle speed and torque, so higher speeds are preferable - especially for aluminum.

Does the spindle ever trip a breaker if you indeed have it on a 230V wall socket? Oh, also, how many other spindles did you try or research to decide this was "the best"? It seems like there are zillions of suppliers out there and it's almost impossible to make an objective comparison.
@PiotrFoxWysocki 4 жыл бұрын
yes i power my cnc out of 240v, on 10A wall sockets but i have 20A breaker. i havent changed anything it was like this when i got the house. For example washing machine is 2.0kw and drying machine is 2.2kw. and if you want to run them at the same time you need more than 10A breaker. nothing burnt down yet(8years so far) :) about spindles, this one will be my forth spindle. and i have seen plenty more up close. Jianken spindles build quality is remarkable. they work amazingly well. and as you mention, there is zillions of suppliers out there, finding one which is really good is really tricky. so when i finally found one i had to share. i know how frustrated it was for me trying to find a decent supplier. Is it the best spindle out there? definitely the best i'v seen so far. I did not haste with this statement. in comparison to most of KZfaq hasty reviews i used mine for over a year, so i could give the most informed opinion.

@@PiotrFoxWysocki oh, that's lucky to have 20A breaker. I'm struggling with a 10A fuse. The Jianken spindle does actually seem to be not a bad deal as I see comparable ones from EU suppliers are much more expensive with similar features. Thanks for reviewing it. The quietness is very attractive. ...somewhat related: I wonder if the increase in noise vs. rpm's in your spindle new vs. after one year of use that you showed being tested has any relation to the most used rpm speeds you used during the year....like maybe the rpm's that were most often used got the most worn out? Or maybe it's simple where some internal resonant vibrations lie and after a year of use those vibrations wore away at their boundaries.

@@perspectivex noise might be misleading, i have moved vfd in to slightly noisier spot, and audio might be not so accurate either, different workshop layout. what is most accurate are the vibration readings. I can't say that the spindle get louder after a year. because it is a very subjective and my judgement from year ago might not be accurate. app is :) speed vs use. i use 9000rpm for drilling. vibrations in this range went way down. 18000rpm for most milling. no difference there 20000rpm for small bits and chamfer. this spindle is very well balanced but there is always some imperfections which cause bigger or smaller resonant vibrations at various speeds. ceramic ball bearings need time to stabilize. this could be also a factor. long story short. there is a lot of science behind it. I'm not particularly interested in knowing exactly what and where, since its not me who is making those spindles :) I'm happy i was able to find a very good manufacturer back to breaker. why you just wont replace it with 20A? or 15A or just something more than 10A. anyway i think you could mill with 10A breaker, just don't go crazy on the cuts. when I"m milling, I'm trying to stay under 5A most of the time. it might be 2.5kw spindle but it doesn't mean it has to be use at the limit all the time.

@@PiotrFoxWysocki I sorta have the same issue. my machine is 300mm travel, so getting many tools in a tray format doesn't work. The best (simple) idea ive seen so far is a round carousel with a pie slice cut from it. The pie slice means the carousel it out of the work area in its 'stowed" position, and you get tools all around the other side - in my case 12 or so. past that you start needing a separate automated machine that can stage the one tool you need from a 3d rack of many tools. Easily done with an Arduino, but less easy to have the control coordinate with it as it needs to know both the tool you have, the tool you want, and the tool you want next that to be efficient.

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?
@wernerautomation2834 4 жыл бұрын
It wasn't working "fine" at 10 amps. it was bogging down. Any spindle can go over its continuous rating for short amounts of time. Mostly what that accidental overload test shows is that the rated numbers are truly the "continuous rated" numbers. Sometimes the number they put is the max current, and not the continuous (like they do on your bosch or Makita router for example).

@@wernerautomation2834 OOPs - I guess it was actually 8.9 Amps rather than 10 Amps. So, spindle power input is 8.9A * 220V * 1.73 = 3391 Watts. At 60% efficiency, that's 2035 Watts output. Power ratings for HF Spindles (and most motors), unlike routers, should be continuous output power rather than input power. If properly rated, Piotr's "2500 Watt" spindle should not have been bogging down, and IMO, doesn't appear to have been. Why do you think it was? However, the spindle is supposedly rated 2500 Watts @ 6.6 Amps and 220 Volts. So, the rated input power input is 6.6A * 220V * 1.73 = 2512 Watts. At 60% efficiency, that's 1500 Watts output. Maybe it's rated based on input power, like routers? That's why I asked about performance curves (speed vs torque) which unlike other Chinese manufacturers, Jianken advertises.
@wernerautomation2834 4 жыл бұрын
@@gmack4097that spindle has 0.89nm torque at 24000rpm for 2.24kw output power (and 2.5kw input assumably). They do not provide a duty cycle, so we can only assume this is both continuous and truthful before testing. The bogging, it is quite audible, with every cut having a continuous tone except those 8+ amp heavy ones. The drop in tone mean the spindle is slowing to a point on its curve where it has more torque available. Because we know this is a flat torque output spindle, we can assume it is operating above it's continuous rating of 0.89nm in that cut. A quick check of the sandvik calculator says the 10mmx4mmx3m/m cut with a sharp 3 flute needs 1.31nm - well above the continuous rating and completely consistent with the 9A draw vs the 6.6a continuous rating.

@@PiotrFoxWysocki with steel, and larger cutters, you cant usually run as fast as 24000rpm. This is why steel is an issue with these styles of spindles, not because they don't have the power or rigidity. As you may have been told by jinaken, they don't recommend running under 12-15k rpm, so, a good test would be to see what happens. A good vector drive will run the spindle from zero hard, but the cooling may not be sufficient. Do the math to make a 1.25kw cut at 12000rpm and watch the water temperature. Then repeat at 600w and 6000rpm. Keep an eye on the temps, amps and the e stop :)

you should try cryo treating your cheep endmills. Basically, you chill them in liquid nitrogen for a few hours. This extends the hardening process from heat treatment, you do not have to heat the bit either. Just ambient to cryogenic temp and then let normalize. The hardness goe's up, and tool life and tool sharpness life goes up. Heres a vid explaining it better, and testing it - demonstrating the process. Its fair cheap and easy todo.
