Description
また、飛散した研削材によってワークWが損傷しないようにキャッチャ22の内径を大きくすると、キャッチャ22が大型化し、キャッチャ22がワークWの下面に衝突して、ワークWが損傷してしまうおそれがある。
本発明に係るアブレイシブウォータージェット加工装置は、ワークを所望の形状に切削加工する際、アブレイシブが混入された超高圧水を噴射するアブレイシブノズルアッセンブリと、前記アブレイシブノズルアッセンブリから噴射された前記超高圧水を回収するキャッチャーカップと、前記キャッチャーカップと前記ワークとの間隔を一定に保つように、前記アブレイシブノズルアッセンブリと前記キャッチャーカップとの間隔を調整する間隔調整機構と、を備えている。
また、アブレイシブの含まれた超高圧水が取りこぼしなく回収されることとなるので、超高圧水の回収率を高めることができ、飛散したアブレイシブによるワークの損傷を防止することができるとともに、作業者の労働環境を改善することができる。
さらに、キャッチャーカップがワークに対してより近い位置に(最適な位置に)配置されることになるので、切削加工中の音を低減させることができ、作業者の労働環境を改善することができる。すなわち、特許文献1等に開示された従来のものでは、切削加工中の音(騒音)が100db程度となっていたため、近隣にいる作業者は耳栓等の着用が必要であったが、本発明に係るアブレイシブウォータージェット加工装置では、耳栓等の着用が不要となり、会話ができる程度の音に改善された。
さらにまた、キャッチャーカップ12がワークWに対してより近い位置に(最適な位置に)配置されて、キャッチャーカップ12の小型化(小径化)が図られることになるので、ワークWとの干渉回避性能を向上させることができ、従来よりも狭隘な箇所にアクセスして切削加工を行うことができる。
さらにまた、高価な耐摩耗材料からなるキャッチャーカップ12の小型化(小径化)が図られることにより、コストダウンを図ることができる。
これにより、間隔調整機構、アブレイシブノズルアッセンブリ、キャッチャーカップを移動させる機構(構成)を最も簡略化することができ、設備費や保守点検費等の費用を低減させることができる。
