Thanks for the heads up! Just looked yesterday for sales and didnt see it then. Got it just now.
There was a 10% anything coupon over the weekend (and today) so I picked up the HF 2HP dust collector. The 20% always excludes Central Machinery so figured that’s about as good as it will get.
Ive briefly scanned the thread to try not to add something that has been discussed 100 times already, I was curious if this option has been discussed?
65mm 1.5KW air cooled spindle and drive w/ input power 110V nominal
That’s the one I’ve been thinking about or at least similar specs. Going to be awhile but hoping not to use up my last 220 in my garage.
That’s the good thing with that one it’s 110 nominal to the drive
That looks similar to what Ed (@EdwoodCrafting) has. He posted a link on Aliexpress - less expensive, but a lot in shipping - still might be cheaper overall.

I am not regretting getting an air-cooled one bit. no water hassles to deal with or worry about. The noise difference at all but the highest speeds is minimal . The only real advantage of a water-cooled is you could run slower. An air-cooled needs to be ~7000 or higher RPM for the fan to cool.
The water cooled 2.2 kw 220 v HY spindle has a minimum speed of 6k rpm. So that doesn’t get you much of a lower speed.
Oh I didn’t know that. I was thinking low rpm was the main advantage of water cooling.
This is the one I had in mind:
Gets down to 4000 rpm. The chap selling it believes the 1F is not robust enough to handle it; primarily, its weight. So I’m waiting to hear what others discover while I’m waiting for the 80mm mount to arrive.
The specs didn’t include the weight of the spindle (that I could see), but it looks very similar to the spindle I’ve picked up - and similar to the ones that lots of others are already running successfully. Here’s a similar water-cooled spindle: High-Torque Stepper Motor, Stepper Motor, Driver, Stepper Motor kit, DC Servo Motor, DC Servo Motor kit, Stepper Motor Power Supply, CNC Router, Spindle, and other Components. - the specs list 15 pounds as the weight, which I think the 1F can easily handle.
I am choosing to upgrade to the X50 rail (not expanding to the Journeyman width though) to provide additional support for the heavier spindle - but that might be over-kill.
I also noticed that their specs show that they don’t connect the 4th (ground) pin - while that will work, connecting that pin to ground and carrying it through the system would be better.
I would also be interested to know the details of the bearings. In my research I have found 3 to be common for a spindle in this price range. What I have not seen before is no detail other than the description of ‘custom’. I am guessing the the lower pair might be angular contact, and all three with steel races and bearings, but I might contact them to find out exactly what they are - they might even tell you what ABEC rating they are, and even about the expected run out of the spindle as well. I found I often had to email suppliers to get this information, and in most cases for the spindles I was comparing the answers were quite similar - still worth asking in my opinion.
Weight is 7 kg with mounts. So all about the same weight.
Can you help. What would be an acceptable/good ABEC rating, runout and bearing construct in our 1F context?
Pease know that my experience is limited to what I have read, and from my research the lowest ABEC ratings - 1 or 3 - are the most common and least expensive and will be more than good enough for the work we do on a hobby CNC like the 1F. The tolerances would usually be to the 4th decimal place, same for run out. The spindles I looked at from JianKen had a runout of 0.01mm (~0.0004").
The forums I am a member of have stories of inexpensive Chinese spindles performing well, and about the same amount of people said they had bad experiences - bearings claiming to be better “German made” but upon inspection were not, or bearings failing after a few weeks of normal use. Many said after sales service/refunds were a challenge. The price for these spindle/VFD packages is in many cases so low I imagine most buyers are willing to take a chance, and perhaps even take the ‘hit’ of losing the ~$200-300 if their spindle fails.
Hey Charley. I just started checking into the Onefinity CNC and noticed you utilize a spindle for your CNC. Can you tell me the make/model of the spindle you went with? Was it 80 mm? if so, did you have to modify the 65mm holder on the Onefinity CNC? Thanks in advance, Charley.
Onefinity has recently introduced an 80mm mount for those wanting a larger spindle. You need to add it as an extra, as their CNCs ship with the 65mm mount only - at least at this point in time.
I don’t have the spindle on my OneFinity. I have left it stock so I can use it for training video’s aqnd such. I do have one on my cusdtom built cnc. It is a 110 volt 2.2KW water cooled spindle with a Huangyang VFD. Eventually I will have one just like it on my 1F.
Thanks for the information, Charley. I appreciate your response.
Thanks for your reply. Do you know if the laser will mount on the 80mm mount? I’m interested in purchasing the laser too which is why I’m asking.
I do not have the laser but do have both mounts. The mounts both use M5 screws for mounting the laser, but the hole spacing is different between the two. I have not looked into mounting the laser, so there may be information on the 1F site or this forum. I am sure others who know will answer your question soon.
