DEVICE AND METHOD FOR IMPROVING WORK SURFACE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a device and a method for improving the surface finish and completeness of a work. <P>SOLUTION: The method and the device improve the surface finish and/or surface completeness of the work molded or shaped by a tool 12 to increase the surface hardness of the work in molding or shaping the work 22. Additionally, the method and the device increase the surface hardness of the work in molding or shaping the work by the tool and to mold or shape the work and to manufacture a completed part or a product from the work. It is possible to jet an expansion jet of an extremely-low temperature material to the surface of the work and the tool from a nozzle in a part of forms, and the extremely low temperature material is at least partly separated into a condensed phase and a steam part in a downstream of the nozzle. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
