Hiki i nā mea wili ke hana i nā mea me ka paʻakikī kiʻekiʻe, e like me ke kila paʻakikī, ka paʻa paʻa, etc; Hiki iā ia ke hana i nā mea palupalu, e like me ke aniani a me ka granite. Hiki i ka mea wili ke wili me ka pololei kiʻekiʻe a me ka liʻiliʻi liʻiliʻi o ka ʻili, a hiki ke wili pū me ka hana kiʻekiʻe, e like me ka wili ikaika.
Ka Moolelo Hooulu wili
I nā makahiki 1830, i mea e hoʻololi ai i ka hana ʻana i nā ʻāpana paʻakikī e like me nā uaki, nā paikikala, nā mīkini humuhumu a me nā pū, ua kūkulu ʻo Beretania, Kelemānia a me ʻAmelika i nā mea wili me ka hoʻohana ʻana i nā huila abrasive maoli. Ua hana hou ʻia kēia mau mea wili ma ka hoʻohui ʻana i nā poʻo wili i nā mea mīkini e kū nei i kēlā manawa, e like me nā lathe a me nā mea hoʻolālā. He maʻalahi lākou i ke ʻano, haʻahaʻa i ka ʻoʻoleʻa, a maʻalahi hoʻi e hoʻoulu i ka haʻalulu i ka wā wili. Pono nā mea hana i nā mākau kiʻekiʻe e wili i nā mea hana pololei.
ʻO ka mīkini cylindrical universal i hana ʻia e Brown Sharp Company o ʻAmelika Hui Pū ʻIa, i hōʻike ʻia ma Paris Expo i ka makahiki 1876, ʻo ia ka mīkini mua me nā ʻano kumu o nā mea wili hou. Hoʻokomo ʻia kona ʻano mea hana poʻo a me ka huelo ma luna o ka pā hana pānaʻi. Hoʻomaikaʻi ka moena pahu pahu i ka rigidity o ka mīkini mea hana, a hoʻolako ʻia me lokowili anamea komo. I ka makahiki 1883, ua hana ka hui i ka mea wili honua me kahi poʻo wili i kau ʻia ma luna o ke kolamu a me kahi papa hana e neʻe ana i hope a i waho.
Ma kahi o 1900, ʻo ka hoʻomohala ʻana i nā abrasives artificial a me ka hoʻohana ʻana o ka hydraulic drive ua hoʻoikaika nui i ka hoʻomohala ʻana onā mīkini wili. Me ka ulu ʻana o ka ʻoihana hou, ʻoi aku ka ʻoihana kaʻa, ua puka mai nā ʻano mīkini wili like ʻole i kēlā me kēia. No ka laʻana, i ka hoʻomaka ʻana o ke kenekulia 20, ua hoʻomohala ʻia kahi mea wili i loko o ka honua, kahi wili crankshaft, kahi pahu camshaft a me kahi mīkini apo piston me ke kīʻaha hoʻoheheʻe electromagnetic i hoʻomohala ʻia e hana i ka poloka cylinder.
Ua ho'ohana 'ia ka mea ana 'akomi i ka mea wili ma 1908. Ma kahi o ka makahiki 1920, ua hana 'ia a ho'ohana 'ia ka mea wili waena, ka mea wili hope papalua, ka wili wili, ka mea wili ka'a alaka'i, ka mīkini honing a me ka mīkini ho'opau piha; I ka makahiki 1950, akiʻekiʻe-precision cylindrical grinderno ka mea, ua puka mai ke aniani wili; I ka pau ʻana o nā makahiki 1960, ʻike ʻia nā mīkini wili kiʻekiʻe me ka wili wili laina laina o 60 ~ 80m / s a me nā mīkini wili ʻili me ka hohonu o ka ʻokiʻoki nui a me ka wili ʻana i nā mea kolo; I ka makahiki 1970, ua hoʻohana nui ʻia ka mana kikohoʻe a me ka hoʻohana ʻana i nā microprocessors i nā mīkini wili.
