That is the beauty of the universal dividing head, you do not need high number plates, it is done by differential indexing, where the spindle is geared to rotate the index plate. That is how prime numbers are divided, such as 127 for metric transposing gears.
I don't undersand how a universal dividing head works apparently. My rotary table is 90 to 1 and the universal dividing head is usually a 40 to 1 ratio.
How does this differential indexing work? How can it make large division numbers with a small numbered hole plate?
