How to use an EDGEFINDER?
What is the proper technique for using an edgefinder in a vertical milling
machine? For this example, I'm using one with a 0.200 inch diameter projection, thus 0.100 inch offset from true centerline. Prior to making contact, the 0.200 extension is off center, but a soon as contact with the work piece is made, it seems to be now rotating true (machine is running under power about 150 rpm). Ok, now set x or y graduated dial to zero. BUT, what happens if I advance the table, say another couple of thousands? How can I be sure that the first contact is correct if I can still move the work a tiny bit closer to the indicator without anything happening? Tool made in India (no instructions); Machinery's Handbook says nothing about edgefinders. HELP! |
