The Automatic Cycle Operates as follows :

Rapid approach-coarse feed-fine feed-spark out and rapid return of wheel head and infeed retraction. The total amount of infeed and fine feed along with feed rate for course & fine feeds is also selectable. Interphasing with any type of in-process gauge is also available optionally. For long jobs, selection is available for terminating the grinding cycle at left/right end position of the table.
