Description
また、本発明に係る研削盤は、上記の砥石車と、前記レーザ光を照射し、当該レーザ光により前記砥石車を加工する砥石車修正装置と、を備える。
研削盤10の構成について、図1を参照して説明する。研削盤10の例として、円筒状の工作物Wを回転しながら、砥石車16により研削する円筒研削盤とする。研削盤10は、ベッド11と、主軸台12と、心押台13と、トラバーステーブル14と、砥石台15と、砥石車16と、砥石車修正装置17とを備える。
砥石車16の詳細な構成について、図2を参照して説明する。砥石車16は、複数の砥粒21と、複数の砥粒21を結合する結合剤22と、砥粒21及び結合剤22の間に形成される空隙23とを備える。砥粒21は、例えば、CBNやダイヤモンドである。
本実施形態においては、砥石車修正装置17は、レーザ光により砥石車16のツルーイング及びドレッシングを行う。レーザ光により対象物の加工が行われるためには、レーザ光が対象物に吸収されることが必要となる。そこで、レーザ光が吸収される度合いを表すレーザ光の吸光度Aλと上述した材料の消光係数κとの関係について説明する。
レーザ光のエネルギー密度と、砥粒21及び結合剤22の加工深さとの関係について、図3を参照して説明する。砥粒21は、CBNとする。結合剤22は、ガラス質ボンド材を主成分とし、式(7)にて示す範囲の濃度CADDの添加剤TiCを含む。比較例として、添加剤TiCを含まないガラス質ボンド材である結合剤22を挙げる。
次に、レーザ光によって砥石車16に対してツルーイングを行う場合について図4を参照して説明する。ツルーイングは、砥石車16を構成する砥粒21及び結合剤22を加工することで、砥石車16の表面を成形する。さらに、本実施形態においては、ツルーイングは、ドレッシングを同時に行うことができる。つまり、ツルーイングは、砥粒21及び結合剤22の表面の成形を行いつつ、砥粒21を結合剤22から突出させることができる。
次に、レーザ光によって砥石車16に対してドレッシングを行う場合について図5を参照して説明する。ここでいうドレッシングは、砥石車16を構成する砥粒21を加工せずに、結合剤22のみを加工することで、砥石車16の表面の目立てを行う。
上記実施形態における砥石車16は、複数の砥粒21と複数の砥粒21を結合する結合剤22とを備える。結合剤22は、所定の周波数帯の波長において、砥粒21の消光係数κより高い消光係数κを有する添加剤を含み、結合剤22は、所定の周波数帯の波長のレーザ光により加工される。
上記実施形態においては、本発明の砥石車は、工作物Wを研削する砥石車16の他に、砥石車16に対してツルーイング及びドレッシングを行うツルア(ドレッサとも称す)を含む意味である。つまり、ツルア(又はドレッサ)を、レーザ光によってツルーイング及びドレッシングするようにしてもよい。また、結合剤22における添加剤は、消光係数κが上述した条件を満たすものであれば、TiCの他の材料を用いることもできる。
