Microsystem technology has become one of the fastest growing industries in the world, and there is a large demand for industries that need to manufacture small, high-precision parts, such as bio-medical equipment, optics, and microelectronics, including mobile communications and computer components. . Parts requiring micro-system machining have an accuracy of 5 mm or less and a surface quality of 0.2 mm or less, and the hardness of the parts is also 45 HRC or higher.

Micro-milling is a new processing technology for machining small parts and high-precision parts. Using very small tools (less than 0.1mm in diameter) and achieving very small surface tolerances and high quality surface accuracy, part deformation, increased complexity, the need to machine small features with high precision, and the use of micron-scale Special tools. For example, a workpiece with a diameter of 0.1 mm meets the above requirements in order to obtain a curved surface with high precision. The micro-milling technology needs to achieve the following support: a small-diameter cutter of 100 mm or less; a profile ratio (L/D) of 10 or a high speed of up to 100 Tool; 150000r/min or higher spindle speed; 0.1mm or less machining tolerance; ability to correct geometry.
