Hana ʻia no ke ahonui: Pehea e hōʻoia ai ka emi ʻana o ka wai i ke kūpaʻa o nā kahua granite kikoʻī

ʻO ka pono no ke kūpaʻa o ka dimensional i ke ana pololei kiʻekiʻe he mea paʻa loa ia. ʻOiai ua mahalo nui ʻia ka granite no kona kūpaʻa wela a me ka damping haʻalulu, aia kahi nīnau maʻamau mai nā ʻenekinia i nā aniau haʻahaʻa: Pehea ka hopena o ka makū i kahi kahua granite pololei?

He hopohopo kūpono ia, no ka mea, ʻo nā mea āpau i hoʻohana ʻia ma ke ʻano he mokulele kuhikuhi no nā micrometer a i ʻole CMM e pono e kū i ka mana o ke kaiapuni. ʻO ka pane pōkole: ma muli o ka mea i koho pono ʻia a me ka hana ʻana, kūpaʻa loa ka granite kiʻekiʻe i nā hopena makū.

Ke Kūlana o ka Hoʻopili Wai Haʻahaʻa i ka Metrology

ʻO ka Granite, ma ke ʻano he pōhaku kūlohelohe, loaʻa iā ia kekahi pae o ka porosity. Eia nō naʻe, ʻo nā ʻano kikoʻī o ka granite ʻeleʻele i hoʻohana ʻia e ZHHIMG no nā noi metrology ua koho pololei ʻia no ko lākou ʻano paʻa a maikaʻi hoʻi, kahi e alakaʻi maoli ai i ka liʻiliʻi o ka omo ʻana o ka wai.

ʻO ka granite maʻamau o ke ʻano metrology maʻamau e hōʻike pinepine ana i ka helu omo wai ma lalo o 0.13% (ʻoi aku ka haʻahaʻa o nā ʻano premium, kokoke pinepine i ka 0.07% a i ʻole ka emi mai). He mea koʻikoʻi kēia ʻano no ka mālama ʻana i ka pololei i ka wā lōʻihi:

• Ka Hoʻēmi ʻana i ka Hoʻonui Hygroscopic: ʻOiai hiki i kekahi mau mea ke pehu a ʻūlū nui paha i ko lākou omo ʻana a hoʻokuʻu paha i ka makū (hoʻonui hygroscopic), ʻo ka porosity haʻahaʻa loa o ka granite precision e kaupalena nui i kēia hopena. ʻO ka nui o ka wai i omo ʻia e ka pōhaku he mea liʻiliʻi ia, e pale ana i kekahi loli nui o ka dimensional e hiki ke hoʻopilikia i ka palahalaha o ka mokulele kuhikuhi.
• Palekana Mai ka ʻUlu: ʻO kahi pono kūpono paha ka pale e hāʻawi ai i kāu mau mea hana waiwai. Inā he porosity kiʻekiʻe ka papa ʻili, e mālama ia i ka makū kokoke i ka ʻili. Hiki i kēia makū ke hana i ka pala a me ka ʻūlū ma nā ana hao, nā mea pono, a me nā ʻāpana i kau ʻia ma luna o ka granite, e alakaʻi ana i ka ʻaʻahu mua a me nā ana haumia. ʻO ka porosity haʻahaʻa o kā mākou Black Granite Components e hōʻemi i kēia pilikia, e kākoʻo ana i kahi kaiapuni ʻole-pala.

Ka Haumākū vs. Ka Pololei: Ke Hoʻomaopopo nei i ka Hoʻoweliweli Maoli

ʻOiai ke kūʻē nei ka granite i ka deformation dimensional mai ka haumākū o ka lewa, pono mākou e wehewehe i ka ʻokoʻa ma waena o ke kūpaʻa o ka mea a me ka kaohi ʻana i ke kaiapuni i loko o kahi lab precision:

Ma ke ʻano he poʻe loea i nā Paepae Ultra-Precision, ke paipai nei mākou i nā mea kūʻai aku e mālama i kahi kaiapuni i kāohi ʻia e ka makū, ʻoi aku ka maikaʻi ma waena o 50% a me 60% Relative Humidity (RH). ʻAʻole pili kēia kaohi i ka pale ʻana i ka papa granite akā ʻoi aku ka pili i ka palekana ʻana i ka ʻōnaehana metrology holoʻokoʻa (CMMs, gauges, optics) a me ka hōʻoia ʻana i ke kūpaʻa wela o ka ea ponoʻī.

Ka Hōʻoia o ZHHIMG no ke Kūpaʻa Mau Loa

ʻO ka granite a mākou e koho ai—kaulana no kona mānoanoa kiʻekiʻe a me ka palaoa maikaʻi—hāʻawi i kahi kahua paʻa e kūʻē i nā loli wela a me ka makū. ʻO kā mākou kūpaʻa i ka hoʻohana ʻana i ka granite me ke kaumaha kikoʻī kiʻekiʻe e hōʻoiaʻiʻo ana e loaʻa iā ʻoe kahi papa nānā paʻa a kūpaʻa i ka palaho e mālama i kona pālahalaha mua a me kona kūpaʻa no nā makahiki he ʻumi, e koi ana i ka hoʻoponopono hou ʻoihana maʻamau ma muli o ke komo ʻana, ʻaʻole ka hoʻololi ʻana o ke kaiapuni.

Ke hoʻopukapuka kālā ʻoe i kahi kahua ZHHIMG Precision Granite, ke hoʻopukapuka kālā nei ʻoe i kahi kahua i hana ʻia no nā paʻakikī o kekahi ʻano ana hoʻomanawanui kiʻekiʻe.
