Flat to round with Sb Indexer

[edwardmc]

I'm trying to cut a flat file that is y3.5 x18.75 what I'm geting on the round cut is y1.625 x18.75 by the manual you devide 229.18316 by stock dia. which is 1.25 or a UV of 183.34652 my standerd UV is 183.347. I'm using a pr96 . Any one got a idea.

I should have said I have a prt96. I'm gessing the UV is not right. anyone know which way the UV should change to get more steps. I'm gessing again but I think I need to get twice the steps I now geting

Try using 400 for the unit value then zero the y axis, make a mark on the faceplate or chuck, and make a y move to 3.6. If the indexer makes a full revolution, the unit value is correct.

thanks!! I was thinking that 400 was right as that is the UV for the indexer in normal round cuting.

Thanks!! It worked like a charm. The figures in the manual must be for a file the is larger then the circumference of the stock.
This fourm is the best help a person could have.
