My new spindle and VFD

patrickcues said:
If you dont have one of these. I suggest getting one. It is very quiet and runs great! I can actually have a conversation and cut shafts at the same time now! It is also water cooled. I ran it for 3 days. 12 hours a day. It never even got warm. Which surprised me!! You can get these on ebay. Shipping was a little pricey though!!
I posted up some pics on how I have it mounted!

I set up a 5 gallon bucket with a 300 GPH fountain pump in it. I just plug it in when im using the spindle. As far as the wiring goes. If you can run a 220 line to the inverter then you can run this. It needs 220 input. It puts out 220 3 phase!! It took us a hour to run it over in conduit and hook this up and running. The hardest part was making a way to mount it to my lathe.

I see the output is 3 phase but is your input 3 phase or single phase? Somebody pinch me.

They are single phase on, so run on a std house single phase supply, or 220v single if you are state side. The hz can be 50 to 60 hz and the inlet voltage can be from 210 to 250.
The output is for the spindle drive only and that is 3 phase of varying frequency depending on the rpm desired from the spindle.

hmmm...

The Teco VFD that I got is 120v single phase input and 3 phase output.

Well after using this spindle now for some time. I am very happy to say that I have NOT had any problems with it what so ever.. Still runs smooth as the day I wired it up.

Thanks for the update.

Going back over this thread though, I didn't see it mentioned, but have you measured any run-out on this or used it for inlays yet? I imagine that just turning shafts you probably haven't ran it much at high rpm either. Just trying to get an idea of it's workload with your results.

Thanks again,
Frank
 
I havent used it at all for inlays. All I use this one for is cutting shafts. I run it wide open all the time. I have not checked it for run out. What I can tell you is. I cut my first shaft and set my zero and it repeats everytime...
 
I use several of these, and am building more machines now that will also use them. I use the air cooled model so I don't have to mess with the water thing and they work fine. If it seems like it's getting a little warm, we just blow the dust out of it and it's back to normal.

I have both the original VFD's as well as some Hitachi X200's. I even have one 2 spindle machine that runs both spindles from one VFD.

They work very well for inlays as well. Very low runout. I do prefer the Precise spindle with ATC for inlay work, but that's all about tool changes.

The spindle is holding up very good. Someone asked if it was 3 phase. Yes it is. 220 3 phase. very cheap to run.

220 3 phase INPUT might be a problem with me. I have 220 single phase.
I hate them converters.

Does it consume a lot of water ? Running a 1/4 inlet directly to a saddle valve would be nice so I don't have to keep reloading the bucket.

Royce, how long do you use it before it gets hot ?

Tnx again.
 
The VFD's in general can work with any input phase, single or three. They convert the AC into DC. Then they take the "clean DC" and alternate it again into AC. However, instead of alternating it at 60Hz like city power, the frequency is variable. That's how the speed is changed.

Joey, as these are three phase motors however the VFD creates the 3 phase motors by modulating a DC bus. You will want to make sure that the VFD that you use is rated to except 220 single phase in. This should not be an issue. I am with Royce, for any spindle that I get that I don't want ATC, I would get one of the Chinese air cooled spindles. The only exception is the larger 80 mm water cooled spindle will use an ER-20 collet that goes up to 1/2".

What is to hate??? variable speed, programmable ramp, dynaminc breaking.....All switches can be hook up to use a machine as it normally would.....

I have a 5 gallon bucket of water that supplies mine. I have run mine for over 5 hours straight and never got hot. Barely got warm...

Patrick, be careful of those inlet fittings at the top of the spindle. They will snap off easily. I broke one just looking at it. I got the fitting out of the spindle but a replacement is not easy to get. I did manage to get one however it was easier to take the top of the spindle off, drill, and tap it for 1/8 pipe thread. Then I screwed on an off the adapter.
