The present paper presents the capabilities that thin wire EDM can achieve specially when the process is combined with other micromachining processes like micromilling or micro-EDM. The most important advantage of using thin wires is the capability to manufacture components with smaller dimensions, thinner slots and smaller radii. Some application examples are shown in which the relevance of the process for the production of high precision tooling for micro-injection moulding or micropunching. The process limitations are also exposed in order to better-define the current processing limitations.
