G0704 build in progress

Hi Everyone,

I thought I'd start a thread documenting my conversion of the G0704. I just received my mill a couple of weeks ago and disassembled the head from the column. Not much as of yet to post, but will be posting pics during the construction. Delivery came today which includes my ballscrews and motors and drives. UC100 is one order and should arrive in a couple of days. More to come.

Congrats, and I look forward to your build )

Great project. I am doing the same thing to my G0704. I got it the first of the year and it is slow going. I have it all apart and purchased the ball screws on Ebay (recommended by Hossmachine). All the electronics are finished. I purchased a control enclosure and all the motors and drives from AutomatedTechnologyinc. These will be an awesome CNC for the hobbiest and then some. My 'Y' axis motor will be mounted in the back. (one of Hoss's optional builds) I like the idea of not have the motor in the way when working. Well good luck with the build. I will be posting my slow progress with pics as I go along also.

Good luck,
Marty

First, I'm sorry for not updating this thread during the conversion. I'll give a brief description of what Steve and myself have done as he has helped tremendously and truely is very much appreciated.

We first disassembled the mill into base and column and head. Unbolted all components and started working on the base.

grinding ballscrew of x drive

x axis ballscrew needed to be ground down to allow clearance. The underside of the X base also needed a slight pocket to knock off the rough manufacture cast material

- - - Updated - - -

Faced the front of the Y axis to allow a flush surface for the Y axis

- - - Updated - - -

x axis enlarged to increase x travel

current status working on making the motor mounts

Some Updated pics of the build. Cnc conversion of the mill is complete and jumps4 and I are now working on the enclosure and electronics box. Should be within a couple of weeks for a test run and will post a walk around video of the build prior to painting the enclosure. I have to say this is one awesome conversion and I can't wait to fire it up.

great job looking forward to watching this one :thumbsup:

Thanks for all the pics! Very interesting !

Holly COW!!!!! That enclosure is fantastic!!! I have never ever seen such a sweet idea and I have seen my fair share of machining centers and water jet tables over the years. I am assuming that you plan to use flood coolant correct? Are you planning to have a plexi center front section so you can visually inspect progress as you go? That is a fabulous enclosure and since Steve is helping you I know it is tack welded together nicely along all of the seams and will be water tight once you caulk in the seams as needed. Have you designed the separator for the coolant. Are you planning to use Rare earth magnets for the ferrous and gravity for the non ferrous. You could even use a catch basin and a strained reservoir. Duda diesel makes some excellent custom fine mesh stainless screen devices for the brewing and biodiesel industries so they could surely make a micron sized coolant filter that would be permanent and cleanable. LMK if you need a POC over at Duda. I use their thermowells and stainless stuff for my beer brewing gear. It's almost all custom 304 and 316 stainless from them and a couple of other guys I use with really good prices. Please keep the pics coming, I am definitely getting a rise from this voyeuristically.....
