Excello Thread Grinder Servo Retrofit

The goal of this project was to completely eliminate the need for the machine to use the hydraulic motor for controlling the machine.  With using a Micrologix 1100 and Cmore EA9 HMI we were able to retrofit this machine to function with a servo motor running the table/head stock.  There is a linear scale used for positioning of the table.  Programmable speeds and positions for each step of the threading process.  The customer can select from 100 savable/editable jobs and only has to replace the tooling and gearing in the machine to achieve the proper thread pitch.  The most difficult part of this application was the constantly changing gear ratios from the servo motor to the movement of the table.  A routine was programmed into the PLC to calculate the gear ratios when a new job is ran for the first time.
