FIXING METHOD OF DRESSING TOOL AND DRESSING TOOL

To provide a dressing tool which prevents a pushing part of a pushing mechanism (pendulum-type cramp) provided on a spinner table from piercing the dressing tool not to be pierced by the pushing part.SOLUTION: A dressing tool is retained by a spinner table of a spinner unit including a plurality of pushing mechanisms which is respectively arranged on outer peripheral parts of the spinner table, has support bodies containing pushing parts, and rotation shafts penetrating through the support bodies and where the support bodies rotate upon rotation of the spinner table to displace the pushing part to the inner side. Therein, a base plate and a dressing member arranged on one side surface of the base plate are provided, a plurality of clearance grooves which penetrate the base plate vertically and arrive at the outer periphery of the base plate are formed on an outer peripheral part of the base plate, and the plurality of clearance grooves are provided on the outer peripheral part of the base plate in such an arrangement that the pushing part can enter the clearance grooves when the spinner table is rotated in such a state that the base plate is retained by the spinner table.SELECTED DRAWING: Figure 3 【課題】スピンナテーブルに設けられた押さえ機構（振り子式クランプ）の押さえ部が突き刺さらないドレッシング工具に突き刺さることを防止する。【解決手段】スピンナテーブルの外周部にそれぞれ配設され、押さえ部を含む支持体と、該支持体に通された回転軸と、を有し、該スピンナテーブルの回転時に該支持体が回転し該押さえ部が内側に移動する複数の押さえ機構を備えるスピンナユニットの該スピンナテーブルに保持されるドレッシング工具であって、基板と、該基板の一方の面に配設されたドレッシング部材と、を有し、該基板の外周部には、該基板を上下に貫通し該基板の外周に達する複数の逃げ溝が形成されており、該スピンナテーブルに該基板が保持された状態で該スピンナテーブルが回転したとき該押さえ部が該逃げ溝に進入できる配置で複数の該逃げ溝が該基板の外周部に設けられている。【選択図】図３
