The Present Situation and Development of Small Holes Machining Technology

It is one of the concerns problems in machinery manufacturing industry of the small holes machining and people has been committed to improve the machining quality, efficiency of the small holes and reduce the machining cost, realized the machining of the small holes on the difficulty-to-machining material. There are some kinds of technology for the small holes machining. For the questions in the small holes machining, based on the up to date development of the small holes machining technology, the application and research current situation of the Mechanical Machining and the Non-traditional Machining such as Laser Machining, Electrochemical machining, Ultrasonic Machining, Electric Discharge Machining and so on in small holes are summarized. The development prospects of various complex machining methods for small deep hole machining in the future are also described in the paper. (paper)
