I have seen an exploded diagram of this arm assembly, but I don't recall where at the moment. I'll keep this in mind and pass it along if I find anything. Hmm, I think here: http://www.wallacecompany.com/machine_shop//Shizuoka/atc_manual/bandit_changer-0064.png http://www.wallacecompany.com/machine_shop//Shizuoka/atc_manual/bandit_changer-0065.png http://www.wallacecompany.com/machine_shop//Shizuoka/atc_manual/bandit_changer-0066.png http://www.wallacecompany.com/machine_shop//Shizuoka/atc_manual/ The arm slides in a vertical tube with a spiral slot that rotates the arm to or from the tool box or to the spindle as the arm slides up and down. The arm operates at fairly low pressure, so no one gets hurt if body parts get in the way, which is nice. The wrist has a bevel gear which is driven by a bevel gear on the vertical inner shaft which is fixed. When the arm rotates, wrist rotates as well. I tend to think I would make a more robot like arm if I were making one from scratch. The current arm has to remove the old tool from the spindle and put it away before getting the new tool, then load it. Some changers have the new tool ready before making a change. With LinuxCNC on-board there is plenty of control resource available. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
