Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brazing tip used for a specific processing purpose in the process of repairing a brazing pattern such as a brazing denture or a brazing crown in a dental technique. TECHNICAL FIELD The present invention relates to a metal tip forming attachment that is detachably attached to a machining tip.

2. Description of the Related Art Conventionally, for example, a plurality of knife-shaped concave portions are formed as a concave portion forming tip for forming a molten concave portion for implanting artificial teeth in a wax bank (horseshoe-shaped brazing material) and absorbing excess molten solder. A blade having a structure in which the blade protrudes in a comb shape from the trunk portion is proposed, and after implanting artificial teeth in the molten concave portion formed with this, when performing wax filling and morphological modification as finishing formation, It is usual to use a separate finishing chip dedicated to those finishing processes.

However, in the method in which different finishing chips are separately used for finish formation as described above, not only is the equipment costly, but when a new finishing chip is used, the entire finishing chip is heated again. It must be wasted, and that time is wasted. Furthermore, in the above-mentioned finish forming, it is often the case that extra molten wax is generated and it is desired to remove it, but in such a case, conventionally, the tip for scooping or sucking the molten wax is heated again to remove the molten wax. Although the method of dealing with it is adopted, all of them have troubles that are troublesome.
