摘要： A tapered cutting edge portion and a continuous raise portion from the tapered cutting edge portion are ground in an edge portion of a straight grinding raw material so that an eccentricity is not generated. In a method for grinding a treatment device, one end portion of a tapered grinding raw material is inserted between a grinding surface of a grindstone and a pressing surface of a press block, and finishing surfaces opposite each other while having a predetermined dimension, shape, and angle are ground so that a direction in which abrasive grains of the grindstone run corresponds to a direction of a shaft center. At this point, before the finishing surfaces are ground in the predetermined dimension, shape, and angle which are previously set corresponding to an objective reamer, pre-grinding is performed while a necessary finishing margin with respect to at least one of the surfaces, and then finishing grinding is performed to the other surface.

摘要： A dental diamond bar comprising a grinding section which has diamond abrasive grains electrodeposited on an outer peripheral surface of a forward end portion of a bar body. A paint-applied section has a colored paint applied to an outer peripheral surface of a part of the bar body. The paint-applied section is located adjacent a rearward edge of the grinding section. In a method of manufacturing the diamond bar, the colored paint is applied to the bar body to form the paint-applied section. Masking liquid is applied to the bar body to form a masking section. The masking section has a forward edge which is located between forward and rearward edges of the paint-applied section. The masking section extends from the paint-applied section toward a rearward end of the bar body. The masking section is removed after formation of the grinding section.

摘要： A dental root canal cutting tool is formed by mounting a wire rod (3) onto a chuck-head (5). The chuck-head (5) variably rotates and advances the wire rod (3) into a guide (6) having a guide hole (7). A whetstone (9) is disposed proximate the outlet of the guide hole (7) for grinding the wire rod (3) with a taper-like shape. A space exists between the cutting edge of the whetstone (9) and the axial center of the guide hole, which varies in response to the advance of the wire rod.

摘要： An apparatus for the manufacture of a root canal reamer and a method of manufacture of the same. An apparatus for twisting reamer material has a triangular or rectangular cross-sectional opening, a chuck portion holding root part of taper-like reamer material and vice composed of a plurality of vice-claws capable of pressing side faces of reamer material while rotating. The distance between vice-claws and chuck is variable. The vice-claws adjacent to said vice are arranged alternately and are able to be moved back and forth in accordance with thickness of reamer material. The inside opening of vice varies corresponding to the sectional taper of the reamer material. The present invention also discloses a method of manufacturing a reamer which has an enlarged rake angle and a smaller relief angle than conventional reamers. This is accomplished by an inside opening dimension of the vice being a little larger than the sectional figure of the reamer material. When twisted, the twisting force is exerted adjacent to the angular edge of the face regarded as a relief face when the reamer material is twisted, and an angular portion of the edge of the reamer is squashed.
