Nā huinahā Granite a me nā poloka V: Pehea e koho ai i nā mea hana ana pololei kūpono

I ka loiloi ʻana i nā mea hana ana granite pololei, aia ka pono nui i ka mea ponoʻī. ʻO ka granite kiʻekiʻe, e like me ka pōhaku Jinan Green i kaulana i ka ʻoihana, hāʻawi i kahi coefficient haʻahaʻa o ka hoʻonui wela a palekana loa i ka popo a me ka pala. ʻAʻole e like me ke kila a i ʻole ka hao i hoʻolei ʻia, ʻaʻole e wili ka granite i ka hala ʻana o ka manawa a ʻaʻole ia he magnetic, e hōʻoiaʻiʻo ana e mau ana kāu mau ana me ka nānā ʻole i nā loli o ke kaiapuni a i ʻole ke alo o nā kahua magnetic. ʻO kēia kūpaʻa kūlohelohe e lilo ia i koho kūpono no ka mālama ʻana i nā kūlana ISO i loko o kahi keʻena hoʻokolohua calibration.

ʻO kekahi o nā hoʻoholo koʻikoʻi loa i ke kaʻina hana kūʻai ʻana, ʻo ia ke koho ʻana i ka māka pololei kūpono. Hoʻokaʻawale pinepine ʻia nā huinahā Granite a me nā poloka V i nā māka e like me ka Māka 0, Māka 00, a me ka Māka 000 no ka pololei kiʻekiʻe loa. No ka nānā ʻana i ka hale hana maʻamau, ua lawa pinepine ka Māka 0, e hāʻawi ana i kahi kumu paʻa no ka nānā ʻana i ka perpendicularity a me ka flatness. Eia nō naʻe, no nā keʻena hoʻokolohua metrology kiʻekiʻe kahi i ana ʻia ai nā ʻae ʻia ma nā microns, he mea nui ka Māka 00 a i ʻole ka Māka 000. Hāʻawi kēia mau māka kiʻekiʻe i nā ʻae ʻia ʻana o ka flatness a me ka perpendicularity, e lawelawe ana ma ke ʻano he kuhikuhi nui no ka calibrating i nā mea hana ʻē aʻe. ʻO ke koho ʻana i ka pololei o ka huinahā granite kūpono e hōʻoiaʻiʻo ana e mau ana ka pololei a hiki ke hahai ʻia kāu ʻikepili nānā.

ʻO ka maʻalahi o nā mea hana granite e hiki ai iā lākou ke lawelawe i nā hana like ʻole ma ka papa hana a me ka lab. He mea nui nā poloka Granite V no ka nānā ʻana i nā ʻāpana cylindrical. I ka nānā ʻana i ka poepoe, ka concentricity, a i ʻole ka holo ʻana o kahi ʻau, hāʻawi kahi poloka granite V i kahi cradle paʻa, ʻaʻole e kahakaha e kākoʻo pono ana i ka workpiece, e ʻae ana i ka heluhelu ʻana i ka dial indicator pololei.

I ka ʻaoʻao ʻē aʻe, ʻo ka huinahā granite ka mea hana paʻa no ka hōʻoia ʻana i ka perpendicularity. Inā ʻoe e hoʻonohonoho ana i ke spindle o ka mīkini CNC a i ʻole e nānā ana i ka squareness o kahi hale mīkini, ʻo ke ʻano paʻa, ʻākau-kihi o kahi huinahā granite e hāʻawi i kahi ʻike maka a me ka paʻi koke. Ma muli o ka hoʻopaʻa ʻia ʻana o ka pōhaku i kahi hoʻopau aniani, hiki iā ia ke hana i nā ʻano nānā "light gap" i hiki ʻole me nā mea hana metala ʻoi aku ka paʻakikī.

No ka hoʻonui ʻana i ka pono a me ka pololei, ke paipai nei mākou i kahi hoʻolālā kūʻai hui pū ʻana. Ma mua o ke kūʻai ʻana i nā mea pākahi, pono nā keʻena maikaʻi e noʻonoʻo i kahi hoʻonohonoho like o nā mea hana granite. Hiki i kahi suite piha ke hoʻokomo i kahi papa ʻili granite ma ke ʻano he kumu, i hui pū ʻia me nā poloka V kūpono no ka hana cylindrical a me kahi square granite precision no ke kaulike kū. ʻO ka hoʻohana ʻana i nā mea hana mai ka pūʻulu mea like e hōʻoiaʻiʻo i ka hana wela like a me nā ʻano lawelawe.
