Description
図1に示す粗形ハニカム構造体20(粗加工ハニカム構造体25)を研削して、ハニカム構造体30を得る研削加工において、直径が340mmの炭素鋼、ステンレス製のハブの円周部分の表面に、メタルボンド製のボンド材中に、その粒度が#100、集中度が100であるとともに、その表面にTiが8〜50μmの厚さで被覆されてなるダイヤモンド砥粒が分散、固定された砥石層が5mmの厚さで配設された、外径寸法が350mmのホイール研削部材を120m/sの周速で使用して加工を行った(表5参照)。
実施例1において、研削部材として、ダイヤモンド砥粒の集中度、粒度、砥石周速、ダイヤコーティングの有無を表1〜5に示すように変えたものを用いて、加工を行ったこと以外は実施例1と同様にした。
比較例6の仕様の研削部材を使用したときの、研削部材が使用不可能になるまでのハニカム構造体の加工量(加工可能量)を100として、実施例1〜7及び比較例1〜25で得られた研削部材の性能(研削可能量)を評価し、その結果を表6に示す。
