Manufacturing on an EDM equipped with our high-speed rotating and indexing spindles is an efficient alternative to hard turning or superfinishing for rotationally symmetric parts. Even smallest parts (pins, needles etc.) in stainless steel, hard metal or even conductive ceramics, which cannot be made by conventional processes like turning, grinding etc. can be manufactured efficiently.

Besides high speed rotation, the application of rotating and indexing spindles allows precise indexing and simultaneous machining (controlled via machine control). Thus finest rotationally symmetric structures and precise surfaces and contours can be machined.
