Wire EDM utilizing micro diameter wire electrodes is the next leap forward in technology for ultra-precision machining and surface finish capability of micro-manufacturing operations that require Wire EDM. EDM Department Inc. drills holes as small as 30 microns (0.001″) in diameter to allow wire sizes ranging from 100 microns (0.004″) down to 20 micron (0.0008″) in diameter to be threaded through the workpiece. Micron level accuracy, improved overall part accuracy, surface finish, and metallurgical quality is achieved through the use of cutting edge EDM generator technologies and electrode materials. Surface finishes down to as low as 4Ra microinch without the need for polishing are now achievable using fine Wire EDM techniques.
Typical projects that are completed through the use of fine Wire EDM are for micro-manufacturing ultra-precision applications such as components for fiber optics, miniature and micro connectors, medical and surgical instruments, micro gears and micro plastic injection molding.
