What is Micro Machining?
Micro machining refers to the precision manufacturing process that employs small CNC machines specifically designed to operate at a micro level. This technique utilizes tools such as micro mills, lathes, and electrical discharge machines (EDMs) to produce small parts with exceptional accuracy, achieving features as small as 1 μm.
Controlled by Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) software, micro CNC machines translate 3D designs into precise cutting, milling, and shaping instructions for various materials, including metals, plastics, ceramics, and silicon.
