Twion City EDM Micro hole

Twin City EDM's microhole popping and burning.

Twin City EDM and Manufacturing's micro hole EDM services are used to produce small holes ranging from .002" to .125" in any conductive material including traditional metals such as stainless steel, tool steel, and titanium as well as more exotic materials including Inconel, Nitinol, gold, molybdenum, and conductive ceramics. The company’s CNC controlled 5-axis EDM is equipped with a robotic arm, automatic tool changers, and bath capability. Twin City EDM & Manufacturing can produce precision hole patterns in pieces up to 24" x 25.5" x 12" with an accuracy of ±.00002" and repeatability of ±.00005".

This precision micro hole popping process is typically used in the manufacturing of hypodermic needles and surgical tubing. At Twin City EDM & Manufacturing, the facility is ISO 9001:2008 certified, and compliant with ISO 13485:2003, to meet the medical device quality management system regulations and standards. In addition to the medical industry, we have experience serving the aerospace and defense industries, and comply with all applicable ASTM and Mil-Spec standards.
