Abstract

PURPOSE:To machine a fine hole in tubular body in an accurate manner, by insetting a metal wire in the metal tubular body and filling a ceramic body, while applying electro-discharge machining to the metal wire in the metal tube being plastically machined in advance. CONSTITUTION:A stainless-steel wire 2 of SuS304 is inset in a sheel metal tube 1 composed of stainless steel, while alumina powder 3 is filled up in this tube 1. Then, the tube 1 of an outer diameter ranging from 10mm. to 20mm. or so is reduced to 2mm. or so by means of plastic machining. At this time, a diameter of the metal wire 2 is 0.3mm.. With the electro-discharge machining applied to the metal wire 2 via an electrode (unillustrated herein), high temperature treatment and impact are added to the metal wire, thus a fine hole is machined so accurate a degree.

Description

【発明の詳細な説明】 本発明はセラミックに微細孔を加工する方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming micropores in ceramic.

従来からセラミックは非金属であるが故に孔加工を放電

しかし最近時放電加工も微細放電加工では極めて微小量

施することができる。However, in modern electric discharge machining, ultra-precision machining can be carried out because micro discharge machining allows machining using an extremely small amount of electric discharge.

It is the material. 6 is alumina powder. This is 1 of the outer diameter
The material is filled into a stainless steel tube with a diameter of about 0 mm to 20 mm, and is then processed through plastic processing using dies, lawns, etc., and the area is successively reduced to an outer diameter of 2 mm, with an inner core wire of 05 mm.
From millimeters to minute diameters, the outer diameter of 1 is about 0.1 mm in 0.5 mm. Furthermore, if bH processing is performed to an appropriate iE, one with an outer diameter of 02 mm can be obtained, and the core wire at that time is o, os mi! It is ranked J. Figure pIS2 is a cross-sectional diagram of Figure 1. FIG. 6 is a partial view of the two core metal wires being subjected to electrical discharge machining. 4 uses a tungsten electrode with a minute diameter, which is an electrode for electrical discharge machining. In this way, the core wire part is subjected to electrical discharge machining, which is extremely small, but it is exposed to high temperatures and shocks, making it possible to process not only the core wire part but also the ceramic part that covers it. I can do it.
