I agree that there is some information that is similar across all types of changers. But routers generally have a tool rack, which the spindle moves to, to do the tool change. Whereas with knee mills you usually move the tool to the spindle. Plus, it's less desirable to use up work space on the table for a rack. The type of tool holders, the nature of the chips, and cost, I believe, will also have a big effect on the design. We certainly could use more tool changer information on the wiki. I need to try to do better, and I look forward to seeing how your projects progress. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
