Micro Milling - EDM Department


Tighter Tolerances equal better finishes. Design it and we will mill it for you. We offer both precision and micro milling capabilities with tight tolerances of 2-3µm, even for micromachining. Working with our vast network of suppliers, we have access to any tool needed to meet your milling, micro milling or micro manufacturing needs. Constant development of new and improved machining techniques allows us to continuously offer our customers tighter tolerances and better finishes.
