Re: Have Tree 310 w/ 3 phase power. Best solution to hook to my shops Single Phase 24
Thanks, Jim. I have some various NMTB tooling for another mill and I tried to insert it in the spindle on the Tree 310. Even when I took the nut off, the outside diameter of the flange was too big to work with it. I believe this is an Erickson 30 QC spindle, but I'll have to try to find some brand name Erickson, Kennametal, or Valenite tool holders... the one's I've seen are pricey...

Do you have the control documentation? Generally most CNC systems have a dual controller, one for the CNC (motion) and one for the PLC (M,S,T codes) , the PLC usually has an output to turn on the spindle, at minimum.
If it does have a M3, M4, M5 even if no S command , you may be able to use this for the VFD.

I have the Dynapath book, plus some drawings, but I haven't gone through them, yet. I'll do some looking and hopefully find more information. I'd like to use a VFD as my Trak lathe uses a 10hp RPC, and I'd like to keep the load on my circuits down as much as possible.
Thanks for your information,

I did buy some standard NMTB 30 holders, I just turned down the flange, and also narrowed it up a bit.

How did you narrow up the flange? There's instructions available from Erickson on how to narrow the flange, and the dimensions, etc. but they say to use a cylindrical grinder--for accuracy I suppose.
I don't have access to a cylindrical grinder, but I do have a 12" lathe with a 4 jaw chuck. I maybe could rig up a tool post grinder but I hate to get grinding grit on the ways, etc.

I just used my 13 inch lathe and carbide tool bits, the $2.00 ones from Harbor Freight, 1/2 inch AR-8, but I suppose any decent carbide bit would do.
I didn't take any material off of the bottom of the flange, only the top. That way the original concentricity is not disturbed, the top of the flange should not touch the spindle nose before the taper is fully engaged, there should be a bit of clearance between the flange and the spindle nose when seated in the taper.
Over the years I have scrounged up some genuine Erickson QC holders at pretty good prices, so they are out there if a bit hard to find. EBay is a pretty good source as is Craigslist.

Ok... I thought a good carbide bit might do it. I'm a little confused, though... all of the toolhoolders I checked had a gap between the spindle nose and the toolholder flange, what I understand you calling the top of the flange. It seems to me that if the collar's too thick, you'd have to take material off the tool bit side (bottom??) of the flange to allow the collar to operate.
Just wondering...

OK, a senior moment, I'm 70 so I can have those. :) I did those about 5 years ago. You made me get up from my chair and go out the the shop to look at a modified tool holder. You are correct, I did take the material off of the tool bit side.

LOL No problem. I'm 65, and my senior moments are turning into hours... thanks for all your help.

The 310 has no spindle drive, the hole in the panel for spindle was only for J325/J425 machines that had a VFD for spindle control. The control and drives are single phase, and I don't think the 310's came with a coolant pump which was 3 phase.
I would get a 3-4hp VFD and wire the spindle motor to that, and use single phase for the rest of the machine, or just use it as a phase converter.

Thanks, that's good to know. I think I'll follow that route.

Re: Have Tree 310 w/ 3 phase power. Best solution to hook to my shops Single Phase 24
Ok, so long time since I posted to this thread. After spending almost 3 years trying to get my shop set up, I came to the realization I need to just get rid of some of my machines as I'll never have time to get them working and learn how to program them. So...
I put the Tree 310 up for sale. However, I still haven't figured out how to isolate the spindle so I can run it with a VFD and use single phase power for the rest of the controls, etc.
I thought I had a manual with drawings, but, after 3 years I can't find them.
So, I'm asking for some help... I have uploaded some pictures that show the wiring. The 240 V 3 phase comes into a smaller cabinet (Electrical cabinet.jpg) at the back of the machine. There's a main switch on the right side (when looking at the panel), and wires running to the lube motor which is 3 phase. There's a number of contactors or relays, but the 3 phase power leaves the cabinet on the left side. It is a bundle of red and black wires with one green ground wire, which can be seen in the picture.
Once the wire enters the larger cabinet (CNC Cabinet.jpg), it goes through 3 fuzes, then two of the wires, L1 and L2 go into Transformer 2 (the smaller one above the much larger Transformer 1) and also to the small relay to the left of the transformers. The 3rd wire from the fuzes--the red one on the left at the bottom of the fuzes, goes up to the top of the large terminal block which is labeled "AC Bus Input" (upside down in the red area at the top) on the right of the Baldor drivers.
The controller is a Dynapath Delta 20M (Dynapath D20 Tag.jpg). The machine serial number and info is shown on the picture (Tree 310 Data Plate)
So, I hope that is enough information that someone could help me know where to disconnect the 3 phase power and run it directly to the spindle motor, and where to connect single phase power (240 or 120 V as needed).
I have a static phase converter that's rated from 2 to 5 hp, and have a 7.5 hp VFD coming that should be here Monday. I'd appreciate any recommendations you might have.
Thanks in advance for your help.

The static Phase converter will not be of any use, and you should not even try and use it.
The VFD Drives input power will be connected using L1 and L2 Plus Ground, if you have something in your cabinet that needs 120v then you will have to have a 4-wire supply that would have L1 L2 Neutral and Ground
The VFD Drive will connect direct to the spindle U V W Plus Ground will need to be a 4-wire Shielded cable this will go direct to the spindle motor and the VFD Drive output
