I would like to get more information on the tool changer on this lathe. http://cgi.ebay.com/1982-TOS-Engine-Lathe_W0QQitemZ180221313534
I am thinking a Sherline class changer of this type might be a good thing. I am trying to figure out generally how they work. Does anyone have links to this or similar changers? I can see using a planetary gear and electric motor to rotate the head. Then using pins or a notched plate to lock it. One of the details that bothers me is, can I use ball bearings as part of the turret locating system during machining, or will the tool and table locking forces wear divots in the races? The Hardinge turret floats during a tool change, then parks on a notched plate, but doing this electrically instead of pneumatically would be a challenge. The changer above, I believe doesn't float. Plus I wounder if it can be located at intermediate positions or only lock in one of eight positions. Thanks for any help. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
