This app can be used to find the index plate for a dividing head in the process of manufacturing gear wheels. It also calculate the number of holes that you should put in the manufacturing process. Currently it shows all the suitable index plates in the range of 1 to 100 holes. This is very easy to use and very user friendly. You just have to put the gear head full rounds for one rotation ( it is either 40 or 60 in most occasions) and the number of teethes. Looking forward to have your comments in order to make this app a better one in the future.
