Then, the grindstone shape measuring jig S is placed on a predetermined position of the table 21 of the grinder, and the grindstone shape measuring jig S is magnetically attached to the table 21 by an electromagnetic chuck built in the table 21. Then, the upper edge portion of the sample 10 set in the jig S for measuring the shape of the grindstone is ground by the grindstone 20 of the grinding machine formed (dressing) in a predetermined shape and size. After that, the grindstone shape measuring jig S is removed from the table 21 using the removing tool 15, and the grindstone shape measuring jig S is set on the optical measuring machine to measure the ground portion of the sample 10. As a result, the shape and size of the grindstone 20 of the grinder can be known.
【００１４】[0014]
従って、請求項１記載の砥石形状測定用治具Ｓは、研削盤のテーブル２１の上 に載置されるベース部２の左右両側部分に試片取付用立設部３を夫々設け、この 試片取付用立設部３夫々の所定位置に、ベース部２底面に対して直交する鉛直面 ４ａと、ベース部２底面に対して平行となる水平面４ｂとを備えた所定深さの取 付溝４を夫々凹設してなる治具本体１を構成し、この治具本体１の取付溝４の鉛 直面４ａに向って固定ネジ５の先端部分が進退自在となるように、固定ネジ５を 試片取付用立設部３に螺着し、この固定ネジ５によって適宜合成樹脂製の矩形板 状試片１０の両端部分が試片取付用立設部３の取付溝４に固定せしめられるよう 構成して、治具本体１にセットされた試片１０の上端縁部分を研削盤の砥石２０ によって研削できるよう構成したので、適宜合成樹脂製の試片１０を砥石２０に よって研削するだけで、砥石２０の消耗を早めること無く、研削盤の砥石２０の 形状、寸法を正確に測定できるようになる。更に、試片１０の砥石形状測定用治 具Ｓへのセットが熟練を要することなく簡単に、迅速に、且つ正確に行えるよう になり、取扱いが容易な砥石形状測定用治具Ｓとなる。そして、試片１０を砥石 形状測定用治具Ｓにセットしたままの状態で、光学式測定機にこれをセットでき るようになり、試片１０の研削部分を正確に測定することができるようになる。 しかも、砥石形状測定用治具Ｓ自体の構成が簡素で、耐久性に富み、比較的小型 コンパクトに構成でき、その製造も簡単で、量産に適し、安価に提供でき、研削 盤の砥石２０が所望形状、寸法に正確に形成されたかどうかを測定するのに最適 な砥石形状測定用治具Ｓとなる。 Therefore, the jig S for measuring the shape of the grindstone according to claim 1 is provided with the test piece attachment standing portions 3 on both left and right sides of the base portion 2 placed on the table 21 of the grinder.
