Status Quo and Prospet of Ultra-Precision Machining Technology in Japan

Abstract

In Japan, ultra-precision macining technology has grown with an expanded demand of high precision parts that are used for private industries such as OA instruments, optical fiber communication and semi-conductor manufacturing devices, And, the development process is different from in U. S. A Passing 20 years, the technology is now indispensable as supporter of these industries. The technology with the key word of "ultra-precision" is able to produce high value added and display originality over in future. This paper introduces ultra-precision machines and the components technology used.
