Re: grinder question
A crank shaft is held in two indexing pot chucks, one at each end, so that it can be rotated about the axis of its offset pins. The two workheads must allign the ends of the crankshaft accurately and turn in unison.
Interlocks are provided to prevent traverse of the table while grinding, work rotation during wheel dressing, rotation of the work heads with the work unclamped and traverse of the table while workrest shoes are in place.
