Aluminum Bar & Rod — Papa pololei, pololei mai Mill

Hāʻawi mākou i ʻelua papa hoʻomanawanui maʻamau: h9 (ka huki pololei) a me ka h11 (extruded/standard). No ka laʻana, he 49.938-50.000 mm ka lōʻihi o ka 50 mm anawaena i ka h9 tolerance, aʻo ka h11 tolerance hiki ke 49.840-50.000 mm. Loaʻa ka pā ʻāina ʻole me ka hoʻomanawanui ʻoi aku ka paʻa (h6/h7) ma ke noi no nā noi koʻikoʻi. Hoʻopili nā ʻae āpau me ISO 286 a me ASTM B211.

Loaʻa i kā mākou pahu pahu anu i ka pololei i loko o 1 mm o ka mika o ka lōʻihi, kūpono ia no ka hapa nui o ka mīkini CNC a me nā noi hui pololei. Loaʻa maʻamau ka pahu extruded i 2-3 mm i kēlā me kēia mika. No nā noi e koi ana i ka pololei ʻoi aku ka maikaʻi (e laʻa, nā alakaʻi alakaʻi, linear motion), hāʻawi mākou i ka pahu pololei a hoʻomaha i ke kaumaha me ka hoʻomanawanui a hiki i ka 0.5 mm o ka mika ma ke noi.

ʻAe. Hoʻopaʻa mākou i nā lōʻihi maʻamau o 3000 mm a me 6000 mm a hāʻawi i ka lawelawe pololei ʻoki i ka lōʻihi. ʻO ka hoʻomanawanui ʻana he +/-1 mm no nā ʻoki maʻamau a me +/-0.5 mm no nā ʻoki pololei. Hoʻohana mākou i nā ʻili anu a me nā ʻili band ma muli o ke anawaena a me ka nui. Loaʻa nā lōʻihi maʻamau ma waena o 100 mm a me 6000 mm. E hōʻike wale i kāu mau lōʻihi i makemake ʻia me kāu kauoha, a e hoʻokomo mākou i ka ʻoki ʻana i ka uku nominal.

ʻO kā mākou MOQ maʻamau he 500 kg no ka alloy a me ke ʻano. No nā mea maʻamau i hoʻopaʻa ʻia e like me 6061-T6 pahu pōʻai, hiki iā mākou ke hoʻokomo i nā mea liʻiliʻi a hiki i 200 kg no nā kauoha hoʻokolokolo. ʻO nā nui maʻamau ʻole, nā ʻāpana kūikawā, a i ʻole nā ​​​​ʻae ʻana maʻamau e koi maʻamau i 1-2 tons. E hoʻokaʻaʻike mai iā mākou e kūkākūkā i kāu mau pono kikoʻī - hana mākou me ka nui prototype a me ka nui hana.

E koho 6061-T6 inā makemake ʻoe i ke kaulike o ka ikaika haʻahaʻa (310 MPa tensile), ke kūpaʻa corrosion maikaʻi, ka weldability maikaʻi loa, a me ke kumu kūʻai haʻahaʻa. ʻO ia ka koho maʻalahi loa no ka ʻenekinia maʻamau, nā noi hoʻolālā, a me nā papahana e koi ana i ka wili. E koho 7075-T6 ke koʻikoʻi ka ikaika kiʻekiʻe (572 MPa tensile) - nā ʻāpana aerospace, nā ʻāpana hana koʻikoʻi kiʻekiʻe, a me nā mea hana mold. Eia naʻe, 7075 maikaʻi ʻole ka weldability a me ka haʻahaʻa haʻahaʻa o ka corrosion, no laila ʻaʻole kūpono ia no nā hale kai a i ʻole nā ​​​​welded. Inā he kumu ke kumu kūʻai, 6061 nā kumukūʻai ma kahi o 30-40% emi iho ma mua o 7075.

ʻO nā mīkini alumini maikaʻi i nā wikiwiki kiʻekiʻe: hoʻohana i nā mea hana carbide me 2-3 flute end mill, spindle speeds o 10,000-20,000 RPM, a me nā helu hānai o 0.05-0.15 mm no ka niho. E hoʻohana i ka wai hoʻoluʻu a i ʻole ka noe e pale aku ai i ka lihi kūkulu ʻia. No 7075-T6, ʻoi aku ka maikaʻi o nā wikiwiki kiʻekiʻe me nā ʻoki māmā. No 6061-T6, ʻoi aku ka lohi iki o ka wikiwiki e pale i ka hoʻokumu ʻana i nā puʻupuʻu gummy. E hoʻohana mau i nā mea paahana ʻoi loa - ʻo nā mea hana ʻeleʻele ke kumu o ka burrs a me ka pau ʻana o ka ʻili. No ka wili lua hohonu, e hoʻohana i nā pōʻai peck e hōʻoia i ka haʻalele ʻana i ka chip.

No nā māka maʻamau a me nā nui (6061-T6 pahu puni i nā anawaena maʻamau), hiki iā mākou ke hoʻouna i loko o 5-10 mau lā ʻoihana ma hope o ka hōʻoia ʻana i ka uku. ʻO nā kauoha i hana ʻia maʻamau - nā ʻāpana maʻamau ʻole, nā ʻano kūikawā, a i ʻole nā ​​anawaena nui - pono maʻamau i nā lā ʻoihana 15-25. ʻO ka manawa o ka hoʻouna ʻana ma kahi o 15-35 mau lā ma ke kai e pili ana i ka huakaʻi. Loaʻa ka ukana ea no nā kauoha wikiwiki. Hāʻawi mākou i ka nānā ʻana i ka hoʻouna piha ʻana a hiki ke hoʻonohonoho i ka hoʻouna ʻana i kēlā me kēia puka ma o nā huaʻōlelo DDP a i ʻole DAP.
