    I am trying to get it done but in the home stretch. I am waiting for the mill table enclosure to get back from the metal fab shop, it will be powder coated in a bright white. Here are some pics of the ATC. I am mounting it with its own stand which will be adjustable to the spindle of the G0704. I have tested the changer and it works great! The ATC shaft goes through a sealed bearing in the hub. All the weight of the ATC carousel hangs off the ATC enclosure not the motor. There is no way the carousel can come off during normal operation. I built this thing to withstand a crash...lol. The clear path motor works like a champ and has more than enough torque and speed to turn the disk. I was a little worried about the holding torque of the motor but when I push on the tool fork the motor resist and stays right where it is. I have used plastic bolts to hold the tool forks on the disk so that if there is a mishap they will snap and I hope avoid damage to the changer.

    I will add those are not Tormach ATC tool forks. I made those, they were laser cut. I will work on a door for the ATC once I have it all mounted up. The air nozzles work great for blowing off the tool after it is put back in the tray, its part of the M6START macro.

    Ok Update. I have been busy getting all my wires ready to take on the ClearPath SDSK's. I purchased the CP SDSK for the X,Y,Z,C, and my ATC carousel axis. Took me a bit to figure out how to set up the ATC with the new CP motor and how to wire it up using the CnC4PC C32 board. I used the RJ45 cable, cut the end off and made my own connection useing a panel mount Molex connector to the CP motor. Let me tell you the Molex cripping tool is not cheap, but I bought it anyways as now I can wire what ever I want. The Power connector to the CP motor is also a molex connector. I used the panel mount molex connector for the power as well. I did not want the motor wires to be hard wired to the control box. With using the panel mount molex connectors I can unplug all the power and signal wires to the control box. I was a little worried if the CP SDSK motor would work for the ATC but let me tell you that little motor has a lot of holding torque! If the carousel moves it goes right back where it was, it wont forget where it was. I had it all working and it runs very smooth and quiet. Loaded the ATC up with tools and spins the carousel with ease. I had a new back panel laser cut to fit the new panel mount molex connectors. The panel is at the powder coaters getting done in a gloss black. I will put the panel together tommorow with new pics of the control box done and complete. The G0704 enclosure will be done in 3 weeks. The enclosure will be a bright white with LED lights in the top. This project has taken me a long time but had to learn all this stuff first.

    I am also in the process of finishing a 6" rotary table as my C axis. I am making a small scale tombstone for milling out my AR lowers. With this I should be able to mill out 8 AR lowers at a time using the G0704. I will drill the tigger pins in all 8 first then mill the trigger pockets out. With the ATC and this rotary table should make quick work of getting them out the door. The rotary table I bought was like $200 shipped. I took it all apart and in looking at it, I figured a way to make it better and smoother. I am adding sealed contact bearings so that there is no metal to metal like before. I am using the CP SDSK motor to turn the rotary table. In the design I am going to use a locking pin to lock the table while milling out the Pockets. I will just use an electric operated solenoid that will be incorporated into the macro. I will post pics when done.

    You are certainly doing some very nice work..and the pictures are great. I can't wait to see your enclosure.

    Thanks! Has taken me longer than I expected but there is this thing called a JOB that I have to goto to fund my addiction! I will be putting up finished pics of the control box tomorrow if I can get it all wired up in time. To be clear I am not making my enclosure myself as I do not have the tools to do that. I did however weld up the table. The actual end caps on the enclosure are going to be 14 gage steel. I know its over kill but the shop said they would rather not use anything else as they had a lot of the 14 gage. The enclosure panels are all bolt together. They are pressing 1/4-20 studs into the panels then I can just put the stainless nylon locknuts on to bolt the whole enclosure together. Here are a few pics of the chip tray drawer that will slide open to scoop out the chips. I have a coolant tank that will sit under the drawer so the coolant will just draing right back to tank.

    I have a 18x24x3" piece of of granite that will sit on the two middle runners and then the G0704 mill base will have bolts that go all the way through and nut on the bottom side of the runners. I had the bottom of the mill base ground perfectly flat so that there is no rocking of the mill when sitting on the granite. When I bought my mill from Grizzly the base had lots of paint on the bottom and just looked like garbage. After having it surface ground, looks awesome. The other runner is where the 12 tool ATC is going to bolt up. I do not want the ATC bolted to the G0704 column as it is not strong enough for that. My welding is not good but the metal shop said they will clean it up and make it look awesome. By the way just because you can go out and buy a tig welder does not mean you will be able to weld with it right away, I am speaking from experience.

    B42;
    Is the ATC design yours or did you use plans for the build. I'm toying with the idea of building an ATC for my Novakon but if there are plans available, I would definitely be interested. It's hard to believe that all the ATC's presented here on the zone are 1 offs and no one has yet to develop and either present or sell plans (other than Hoss who has been supporting us with all of his great ideas)!
    Very nice system you're putting together!
    Thanks for sharing.
    Bill

    Bill, I have no problem sharing my DXF files on the ATC. My design as all can see is based on many other type carousel designs. The only difference between my own and another very similar one is the hub design. The carousels weight is held up by the ATC motor box. This way the carousel can in no way come off the shaft inside the hub and have all the tools come crashing down. The shaft in the hub goes through a sealed angular contact bearing at the base of the hub. I made it this way to take the side load for when the ATC carousel fork goes in to grab the tool from the spindle. The ATC operates very smoothly with no play at all. I had a thrust breaing in the hub at first not thinking but quickly relised that the shaft in the hub did not have any side load protection. This would of caused a failure or weak down the road. I turned the hub to make it wider and turned the hub shaft down to fit the ID of the new sealed bearing. What A night and day difference it made, very solid. The hub fits throught the ATC carousel box so really the ATC carousel box is holding all the weight of the carousel. I dont have a DXF of the shaft with the new bearing dimensions but I will put up the old one. I will look for the bearing that I used from VXB bearing when I find the model number.

    Oh forgot to add, I had 150 of the plastic tool forks that grip the tool made so that I had extra for when they wear out. I think it cost me $52 total for that and they had them done quick. I used M6x1x30MM HEX BLK nylon bolts to hold the tool fork onto the carousel. I did so that if I were to have a crash it will shear the plastic bolt instead of trashing my machine. I found the bearing number I used for the hub shaft bearing. SKF 60072RS. To be clear the shaft DXF file is not dimensioned to show the new bearing. Some where I have the ATC box drawing that hold everything. I had a nema 34 motor with 5:1 planetary gear box in the ATC box at first but was way over kill so the box drawing shows the dimensions for a NEMA 34 not a NEMA 23. I made parts and modified as I went to get to the way it is now. I still need to make a door for the Carousel cover but I will do that after I have it all mounted and working.
