ʻAʻole nā papa koʻikoʻi ma luna o nā wāwae kila wale nō nā papa hana Granite no ke kūʻai aku - ʻo ia ke kumu leo o ka hana metala pololei. Ua nānā mākou i nā hale kūʻai ma ʻAmelika ʻĀkau a me ʻEulopa e hoʻololi i nā noho kila me nā papa hana granite-a i loko o 90 mau lā, ua lele ka hua mua o kā lākou ʻāpana i ka awelika o 12%. No ke aha mai? No ka mea, ʻoi aku ka nui o ka paʻa wela ma mua o ka paʻa i ka wā e paʻa ana ʻoe i ka ± 0.005″ i ka hoʻomanawanui ʻana ma nā bracket i hoʻopaʻa ʻia a i ʻole nā panel chassis i ʻoki ʻia.
No ke aha ka Granite—ʻAʻole ke kila a i ʻole ka hao hoʻolei—lanakila ma ka hana ʻana i ka honua maoli
Manaʻo ka hapa nui o nā ʻenekinia "kaumaha" ʻo ia hoʻi ke kila mānoanoa. Akā ʻo ke kaumaha wale nō ʻaʻole e hoʻōki i ka haʻalulu. ʻO 3-5 × kiʻekiʻe ka lakene damping o Granite ma mua o ka hao a me 10 × kiʻekiʻe ma mua o ke kila kila. I loko o kā mākou hale hana hoʻāʻo, ua hōʻike ʻia kahi bracket CNC-punched i kau ʻia ma kahi pākaukau granite ʻeleʻele he 68% ka liʻiliʻi o ka harmonic resonance ma 120 Hz ma mua o ka hoʻonohonoho like ma kahi kumu kila welded 2″. ʻO ia ka unuhi pololei ʻana i nā kihi ʻoki maʻemaʻe, nā wahi lua e hiki ke hana hou ʻia, a me nā pōʻai hana hou.
Kū'ē pū ka Granite i ka neʻe wela. ʻIke ʻia kahi hale kūʻai hana maʻamau i ka loli ʻana o ka wela o ka papahele o ± 8°C i kēlā me kēia lā. Hoʻonui/ʻaelike nā noho kila ma 12 µm/m·°C; 0.5–0.8 µm/m·°C wale nō ka neʻe ʻana o ka granite. Ma luna o ka ʻili he 2-mika, he 0.24 mm ka hoʻololi ʻana i ke kila me ka 0.02 mm i loko o ka granite-hiki ke hoʻolei aku i kahi noiʻi CMM a i ʻole ke kuhi hewa ʻana i kahi make kulou.
ʻAʻole mākou manaʻo i ka granite no nā ʻāpana hāʻule nui-e like me nā hale hana forging a i ʻole nā papa kaomi hydraulic. Akā no ka nānā ʻana, ka hui ʻana, jigging, a me ka hana hoʻonohonoho pololei? ʻAʻole hiki ke kūkākūkā. A ʻae—ua mālama ʻo ia i ka hoʻohana ʻana i nā metala maʻamau. Ua ola kā mākou papa hoʻāʻo he 1,200 kaʻina o ke kauo ʻana i nā ʻili kila anuanu 12-gauge ma luna o kona ʻili me ka ʻole micro-scratches a i ʻole ka ʻoki ʻoki ʻana.
ʻO nā mea e pono ai ka poʻe kūʻai aku—ʻaʻole ka mea i hoʻohiki ʻia e nā brochures
Hūnā pinepine nā papa inoa "nā papa hana granite no ke kūʻai aku" i nā kikoʻī koʻikoʻi. Eia ka mea e hoʻokaʻawale ai i nā papa hana hana mai nā paona pepa makamae:
Pili nā papa: ʻO ka pōhakuʻeleʻeleʻeleʻeleʻo ASTM C615 Grade A a iʻole B (e laʻa, Absolute Black, Baltic Brown) e hāʻawi i ka likeʻole a me ka porosity haʻahaʻa. ʻO nā "granite lookalikes" ma lalo o nā haʻawe kiko hoʻomau. Ka hoʻomanawanui palahalaha: ʻAʻole e ʻae i kekahi mea ʻoi aku ka liʻiliʻi ma mua o ±0.002″ ma luna o 1 mika—a i ʻole ±0.008″ ma luna o 4 mika. ʻO nā mea ʻē aʻe e kono ana i ka hoʻokaʻawale ʻana i ka ʻāpana i ka wā o ka hoʻopaʻa ʻana. Ke kau pono ʻana: Pono nā wāwae e kī pololei i loko o ka pōhaku—ʻaʻole i loko o nā mea hoʻokomo epoxy. Ua ʻike mākou i ʻekolu mau papa i hāʻule i loko o 18 mau mahina no ka mea ua hoʻohana nā mea hana i nā ʻōnaehana heleuma adhesive-wale nō. Hoʻopau ʻili: 60–80 grit honed ʻoi aku ka maikaʻi. Hōʻike ka poni aniani i ka mālamalama akā hūnā i nā kaha hoʻolālā; ʻO ka paʻa paʻa loa e hoʻopaʻa ʻia a ʻoi aku ka wikiwiki. Nīnau kekahi poʻe kūʻai: "Hiki iaʻu ke wili iā ia?" ʻAʻole - ʻaʻole hiki iā ʻoe. Nā māwae Granite ma luna o 300°C. Akā ʻo ʻoe hiki e hoʻopaʻa paʻa i nā puʻu uʻi, nā ʻili lepo, a me nā kumu magnetic. E mālama wale i nā kumu wela ma kahi o 150 mm.
Nā Kūʻai Kūlohelohe ʻOiaʻiʻo—ʻAʻohe Lapaʻa Sugarcoating
ʻAʻole kilokilo ka Granite. Loaʻa iā ia nā palena - a ʻo ka ʻike ʻana iā lākou e pale i nā kuhi hewa.
ʻO ka mua: ke kaumaha hoʻouna. ʻO kahi papa maʻamau 2400 × 1200 × 76 mm ke kaumaha ~1,450 kg. Ke koi nei ia i nā pahu hoʻouka i hoʻoikaika ʻia, nā pahu pallet i helu ʻia no 2,000 kg, a ma kahi o ʻehā mau limahana i aʻo ʻia no ka wehe ʻana. Ua ʻike mākou i ka mea kūʻai aku e hoʻāʻo e hāpai i kekahi me ka forklift—ʻoki ʻia ʻelua mau ʻili a nahā ka pōhaku ma kahi laina māwae maoli.
ʻElua: manawa hoʻokomo. ʻAʻole like ka pae ʻana i ka granite e like me ka hoʻopaʻa ʻana i ke kila. Pono ʻoe e hoʻololi i nā wāwae pae, kahi pae mīkini i hōʻoia ʻia, a me 2-4 mau hola ka liʻiliʻi-ʻoiai me ka papahele ʻiʻo. ʻO ke kākoʻo kūponoʻole ke kumu o ka haʻihaʻi kaumaha i ka manawa.
ʻO ke kolu: kumukūʻai. ʻAe, ʻoi aku ka nui o nā pākaukau granite ma mua o 2.3x ma mua o nā mea kila kila kaumaha. Akā, hōʻike kā mākou mea kūʻai aku i ka uku i loko o 14-18 mau mahina ma o ka hōʻemi ʻana i ka ʻōpala, ʻoi aku ka wikiwiki o ka ʻatikala mua, a me ka haʻahaʻa haʻahaʻa metrology recalibration frequency. Hoʻokahi mea kūʻai kaʻa Tier-1 i ʻoki i kā lākou hōʻoia hōʻoia CMM mai kēlā me kēia pule a i kēlā me kēia hapaha ma hope o ka hoʻololi ʻana.
Pehea e wehewehe ai—me ka ʻole e puhi ʻia
Mai kauoha i "ka papaʻaina granite." E kauoha i kēia:
Mea waiwai: ASTM C615 Grade A ʻeleʻele granite, quarried ma India a Palakila (hōʻoia ma ka mill palapala) Anana: Loaʻa pololei × laula × mānoanoa, me ka hoʻomanawanui ±0.5 mm Palahalaha: Hoʻopaʻa ʻia no ASME B89.3.7, hōʻike ʻia ma ke ʻano he ʻokoʻa kiʻekiʻe ma luna o ka ʻili piha Ke kau ʻana: ʻEhā mau mea hoʻokomo milo M16, 40 mm hohonu, i waena 100 mm mai kēlā me kēia kihi Hoʻopau: 70-grit i honi ʻia, ua maʻalahi nā ʻaoʻao i ka radius 1.5 mm Palapala: Hōʻike hoʻohālikelike, palapala hōʻoia waiwai, a me ka pepa nānā nui Hoʻokumu ʻo Botou Haijun Metal Products Co., Ltd. i nā papa hana pōhaku pōhaku maʻamau i kēia mau kikoʻī kikoʻī—ʻaʻole ma ke ʻano he mea hoʻohui, akā ma ke ʻano he subsystem i hana ʻia. Hoʻohui mākou iā lākou me kā mākou mau paʻa paʻa i hoʻopaʻa pololei ʻia, nā wāwae pae kila kila, a me nā pale kaʻawale anti-vibration. Hoʻouna ʻia kēlā me kēia papaʻaina me ka ʻikepili QC hiki ke ʻike ʻia—ʻaʻole kahi sticker wale nō.
Hua'ōlelo Hope: Hoʻomaka ka pololei ma lalo o ka wāwae
ʻAʻole hana ka papa hana i nā ʻāpana. Akā ʻo ka ʻili i hoʻomalu maikaʻi ʻole ʻia e hōʻoia i ka loli. Hāʻawi nā papa hana Granite no ke kūʻai aku i ka ROI hiki ke ʻike ʻia kahi hiki ke hoʻihoʻi, ka paʻa wela, a me ka palahalaha lōʻihi e wehewehe i ka kūleʻa-ʻaʻole i ka ikaika wale nō. Inā ʻoi aku ka paʻa o kāu kaʻina hana ma mua o ± 0.010″, ʻaʻole ʻae i ke kamaʻilio i hoʻoulu ʻia i ka haʻalulu, a i ʻole koi i nā makahiki he ʻumi o ka lawelawe ʻana me ka hoʻoponopono hou ʻole, ʻaʻole koho ka granite. ʻO ia ke kumu.
E kipa i ka haijunmetals.com e noi i kahi pepa kikoʻī dimensional, e nānā i nā noiʻi hihia maoli mai nā mīkini mahiʻai a me nā mea hana hale, a i ʻole e hoʻonohonoho i kahi loiloi DFM manuahi no kāu papahana hoʻohui papa hana.
