Description
technical field [0001] The invention relates to the technical field of precision machining, and more specifically, to a microhole machining device and a microhole machining method. Background technique [0002] In recent years, with the development of complex and miniaturized product shapes, moldless jet printing has become more and more widely used in modern ultra-precision machining, and is constantly moving towards higher jetting frequency, higher viscosity of applicable fluid and jetting liquid The direction of the drop volume is smaller. Jet printing is a non-contact printing process, and the precision of the molded body is controlled by the diameter of the nozzle, generally 25-75um. [0003] At present, micro-holes such as nozzles with small apertures are mainly processed by micro-cutting, electrolysis, electric spark, laser, ultrasonic and other methods. However, it is difficult to manufacture the drill bit required in the micro-cutting method, and the diameter of t...
