I was wondering if anyone can give me some advice on a difficult fixturing problem I have run into.
We are turning a casting that is generally football shaped on the OD. The current solution is to chuck an adapter of sorts with a pocket milled out of the face. We are manually bolting each part to this adapter which is VERY time consuming. The pocket takes care of the rotational forces and the bolts hold the piece flat against the chuck.
The job probably will not support replacing the three jaw chuck with anything more elaborate, a 4 jaw or magnetic, although I think either of these may offer some interesting possibilities.
We really need to increase production, and any ideas would be greatly appreciated.
