A hole 1 for fitting a jewel on a surface-treated pedestal 1
Step D of forming 2 by drilling is performed by automatically performing a drilling process on the surface of the pedestal 1 at a position between the adjacent convex grains 11 using a CNC drill machine. The shape of the bottom of the drill head is adapted to the shape of the bottom of the jewel 3 to be fitted, so that the surface of the pedestal 1 has a jewel fitting hole which is the same as the shape of the bottom of the jewel 3 to be fitted, as shown in FIG. 12 are formed.

In the step E of fitting the jewel 3 into the hole 12, as shown in FIG. 6, the jewel 3 is sequentially fitted and placed in the jewel fitting hole 12 on the surface of the pedestal 1, and the pedestal 1 is placed on a CNC machine. After being fixed on the worktable, the press bar 4 is pushed downward as shown in FIG. As shown in FIG. 7, the bottom of the press bar 4 is in the shape of a cone, and the inclination of the cone is equal to the oblique inclination of the outer edge of the top surface of the jewel 3. Therefore, when the press bar 4 is pushed downward, as shown in FIG. 8, the convex grains 11 on the etched pattern surface of the pedestal 1 are pushed and bent to the oblique surface side of the outer edge of the upper surface of the jewel 3, Is securely fixed in the jewel fitting hole 12.

In the step F of treating the entire surface of the pedestal 1 into which the jewel 3 has been fitted, the stainless steel pedestal 1 and the jewel 3 fitted and fixed therein are subjected to a surface polishing treatment with a polishing machine.

In the step G of completing the product, the jewel 3 is securely positioned in the above-described steps, and the jewel base 1 and other parts are combined to form a wristwatch band and a wristwatch side.
Belt head, eyeglass rim, brooch, ring collet,
Complete products such as pendants.

The above is an ideal embodiment of the present invention, and the present invention is not limited to the above embodiment, and any improvements and modifications in the same spirit as the present invention are covered by the present invention. Is included.

[0015]

According to the first aspect of the present invention, there is provided a process of manufacturing a solid pedestal made of stainless steel, and forming a pattern on the surface of the solid pedestal by performing electrical discharge machining on the solid pedestal and etching the solid pedestal. A step of performing a surface treatment on the pedestal on which the pattern is formed, a step of forming a hole for fitting a jewel in the surface-treated pedestal, a step of fitting the jewel in the hole, and a step of fitting the jewel in the hole. Surface treatment of the entire pedestal, and a step to complete the product,
The solid pedestal is made of stainless steel and is made of a strong material, which solves the difficulty of manual engraving and improves the unnaturalness of machine molding, thus making it easy and attractive It is possible to produce a finished product with a certain quality.
