Hoʻohana ka mīkini shearing hydraulic i kahi ʻōnaehana hoʻokele hydraulic i hoʻohui ʻia, maʻalahi ke hana, holo mālie, hiki ke hoʻololi ʻia ke kihi shearing, a hiki ke hoʻololi ʻia ke āpau o ka lau, i hiki ke pale maikaʻi ʻia ka shearing deformation o ka metala, a me ka parallelism. hiki ke hōʻoia i ka ʻoki ʻana, ʻoki ʻoki i nā papa metala me ka precision kiʻekiʻe. Ua hoʻolako ʻia me ka anana hope kiʻekiʻe, he kūlana kiʻekiʻe kiʻekiʻe, hiki ke koho ʻia ke kiʻekiʻe kiʻekiʻe o ka pōleʻa pōlele a me ke alakaʻi laina, e hōʻoia i ka hana ʻana me ka hana kiʻekiʻe.
