９ねシが表面粗さを劣化させるため問題となる。In conventional diamond cutting tools, the rake face, relief, and face are all polished to facilitate polishing in order to efficiently polish and sharpen. Therefore, as in the example shown in FIG. 1, when the rake face B and flank face A of the diamond chip 1 held by the shank 2 and presser foot 5 are polished in the direction of the polishing marks shown in the figure, Waviness will occur in the edge line C of the cutting edge. These polishing marks are unavoidable in the conventional polishing method in which the cutting tool is fixed and the polishing surface is rotated, and they occur in most diamond cutting tools. Therefore, minute ridges of about 0.01 to 004 μm are formed on the ridge line C. FIG. 2 shows an example of mirror cutting using the conventional cutting tool described above. In the figure, E is equivalent to the feed amount of the tool per revolution of the workpiece, and D is equivalent to the cutting edge C of the cutting tool. The surface roughness F inside this region D is the cutting edge C
It is equivalent to the undulation of If the required surface roughness of the machined surface is 01 to 03 μm/max, then the waviness of the cutting edge is a problem V? :, but if the finished surface roughness is about 001 μml<max, this problem arises because the 9 holes on the cutting edge deteriorate the surface roughness.
本発明の目的は、上記した従来技術の欠点をなくシ、切

減させたターイヤモンドバイトを提供するにある。An object of the present invention is to eliminate the drawbacks of the prior art described above and to provide a diamond cutting tool which reduces the influence of minute waviness of the cutting edge on the surface roughness of the finished surface.
本発明は、上記目的を達成するため、逃げ面を回転して

This product provides a diamond cutting tool made using a polishing method that grinds the rake face to form a cutting edge.By making the flank surface free of polishing marks, the surface roughness of the finished surface of the micro ridges is improved. The aim is to reduce the impact on
本発明の一実施例を図面を用いて説明する。 An embodiment of the present invention will be described with reference to the drawings.

ずに研磨する。FIG. 6 is a schematic side view of a polishing machine used for polishing the diamond cutting tool of this embodiment. In conventional diamond cutting tools, in order to attach the cutting edge 5, the cutting tool is pressed against the rotating polishing plate 9 and polished without feeding, resulting in ridges on the edge of the cutting edge as described above. In order to polish the diamond cutting tool according to the present invention, the feeding device 6 shown in FIG.
Attach the cutting tool 8 to the holder 7 installed above, and after polishing the flank face on the polishing plate 9 while reducing the feed rate so that no polishing marks remain, without applying the feed rate 9 so that the rake face can be sharpened. Grind.

ないことになる。The diamond cutting tool of this example finished by this polishing method is shown in FIG. As shown in FIG. 4, the flank face A has no polishing marks, so there are almost no ridges 9, and the rake face B has polishing marks because it is polished without feeding for cutting. As a result, the portion of the cutting edge C' has ridges in the plane of the rake face B, but has almost no undulations in the plane of the flank A. If there is no waviness within the flank Δ, there will be no effect on the surface roughness of the cut mirror surface.

以上のように、本実施例によれば、−刃あたシの切削鏡

効果は一層大きなものとなる。Note that the effects of the present invention will be even greater in a cutting tool whose crystal orientation is selected so that the direction of easy polishing of the rake face is parallel to the cutting edge ridge.
