    摘要: A circular steel blank (10) having a central opening (12) is first press formed into a frusto-conical shape and then subjected to a heat treating process to provide the unfinished spring with the requisite shape and hardness. The spring is then mounted in the electrical discharge machining (EDM) apparatus to remove material on one side using a first electrode. The spring is then electrically discharge machined on a second side with a second electrode. In this manner a Belleville spring with an exact machining tolerance can be manufactured.
