Furthermore we take Easy Order of soft jaw which makes it possible to adjust length, width choosing from 250 kinds of basic shapes responding to customer requests, and we also take Full Order which makes it possible to correspond to specific shapes.

In May 2005, we acquired "ISO9001" certification by establishing a quality management system. Needless to say, accurate custom-made soft jaws produced in a superior technology and environment can maximize the functionality of the machine tool and contribute to improve performance.

We will continue to improve our skills on the basis of accumulated know-how and contribute to the world as a pioneer who excels at producing all forms of soft jaws by innovating advanced technology enthusiastically.
