Method of manufacturing an openable link of a track

A method of manufacturing a first connecting link and a second connecting link from an individual forging which can be juxtaposed along a predetermined profile to form an openable link for joining a chain of links into a closed loop to form a track, wherein the method comprises the steps of:

• providing the individual forging of said openable link;
• securing said forging in a cantilevered position on a work table, wherein said first connecting link is hangingly fastened by a hanging fastener to said work table;
• cutting said forging along said predetermined profile from one side to the other side of said forging by spark-erosion machining with a wire so that said first connecting link and said second connecting link are provided with juxtaposed, side by side cut surfaces, said first connecting link is formed and separated from said second connecting link leaving said second connecting link secured on said work table in a predetermined position;
• and
• cutting a second return cut along said cut surface of said second connecting link.

• moving said first connecting link away from said second connecting link by said hanging fastener;
• and
• cutting a second return cut along said cut surface of said second connecting link.
