He aha ka ʻoki maloʻo no ka metala?

Ke Hoʻomaopopo nei i nā ʻIli Metala Pōʻai

E like me ka inoa e hōʻike nei, hoʻohana ka ʻoki hao poepoe i nā pahi ʻokiʻoki e like me ke disk e ʻoki ai i nā mea. He kūpono kēia ʻano ʻoki no ka ʻoki ʻana i ka metala no ka mea ʻo kona hoʻolālā e hiki ai iā ia ke hāʻawi mau i nā ʻoki pololei. Eia kekahi, ʻo ka neʻe poepoe o ka pahi e hana i kahi hana ʻoki mau, e hiki ai iā ia ke ʻoki i nā metala ferrous a me nā metala non-ferrous. ʻO ka ʻoki maloʻo kahi ʻano o ka ʻoki ʻana i ka metala me ka hoʻohana ʻole ʻana i kahi wai coolant. Ma kahi o ka hoʻohana ʻana i kahi wai e hōʻemi i ka wela a me ka friction, hilinaʻi ka ʻoki maloʻo i nā pahi i hana ʻia a i ʻole i uhi ʻia i loko, kahi mea e hiki ke kū i ka wela a me ka friction a ka metala e hana ai. ʻO ka maʻamau, hoʻohana ʻia nā pahi daimana no ka ʻoki maloʻo ma muli o ko lākou paʻakikī a me ke kūpaʻa.

ʻO nā pahi ʻoki poepoe i hoʻohana ʻia no kekahi ʻoki metala e hoʻopuka i ka nui o ka wela i ka wā e ʻoki ai i ke kila poepoe, ka alumini a me nā mea kūikawā ʻē aʻe; akā i kekahi manawa pono e mālama i ka ʻāpana hana i ʻoki ʻia a me ka pahi ʻoki i hoʻomaʻalili ʻia. I kēia hihia, ʻo kahi pahi ʻoki poepoe kūikawā o ka pahi mea e hoʻopau ai i ka ʻoki ʻana, ʻo ia ka pahi anu.

ʻO ka mea huna i ka hiki o ka ʻoki anu ke mālama i ka mea hana a me ka lau ʻoki i kahi anuanu ʻo ia ke poʻo ʻoki kūikawā: he poʻo ʻoki cermet.

Mālama nā poʻo ʻokiʻoki Cermet i nā ʻano o nā keramika e like me ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa oxidation a me ke kūpaʻa kemika, a he paʻakikī metala maikaʻi a me ka plasticity. Loaʻa iā Cermet nā pono o ka metala a me ka keramika. He haʻahaʻa kona density, paʻakikī kiʻekiʻe, kūpaʻa ʻaʻahu a me ka conductivity thermal maikaʻi. ʻAʻole ia e palupalu ma muli o ka hoʻomaʻalili koke ʻana a i ʻole ka hoʻomehana ʻana. I ka wā e ʻoki ai, e alakaʻi nā serrations o ke poʻo ʻokiʻoki keramika i ka wela i nā ʻāpana, no laila e mālama ana i ka pahi ʻoki a me nā mea ʻokiʻoki i anuanu.

Nā Pōmaikaʻi o ka ʻoki anu

Hiki ke hoʻohana ʻia nā ʻoki anu no ka ʻoki ʻana i nā ʻano like ʻole, me nā koʻokoʻo, nā paipu, a me nā extrusions. Hana maikaʻi nā ʻoki anu poepoe i hoʻopaʻa ʻia no nā holo hana a me nā papahana hana hou kahi e koʻikoʻi ai ke ahonui a me ka hoʻopau ʻana. Hāʻawi kēia mau mīkini i ka wikiwiki o ka pahi a me nā helu hānai hiki ke hoʻololi ʻia no ka hana wikiwiki a me nā ʻoki pololei ʻole me ka ʻole o ka burr. Hiki i nā ʻoki anu ke hana i ka hapa nui o nā mea hao a me nā mea ʻole-ferrous. ʻO nā pono hou aʻe e pili ana i ka hana burr liʻiliʻi, ka liʻiliʻi o nā huna ahi, ka liʻiliʻi o ka discoloration a me ka ʻole o ka lepo.

Hiki i ke kaʻina hana ʻoki anu ke hana i ka throughput kiʻekiʻe ma nā metala nui a kaumaha - i kekahi mau kūlana, ʻoiai e like me ka paʻa o ka ±0.005” (0.127 mm) tolerance. Hiki ke hoʻohana ʻia nā ʻoki anu no ka ʻoki ʻana i nā metala ferrous a me nā metala non-ferrous, a no nā ʻoki pololei a me ke kihi. No ka laʻana, hiki i nā papa kila maʻamau ke ʻoki anu, a hiki ke ʻoki koke me ka ʻole o ka hoʻoulu ʻana i ka wela a me ka friction.

Kekahi mau hemahema i nā ʻoki anu

Eia nō naʻe, ʻaʻole kūpono ka ʻoki anu no nā lōʻihi ma lalo o 0.125” (3.175 mm). Eia kekahi, hiki i ke ʻano hana ke hana i nā burr kaumaha. ʻO ke kikoʻī, he pilikia ia kahi e loaʻa ai iā ʻoe nā OD ma lalo o 0.125” (3.175 mm) a ma nā ID liʻiliʻi loa, kahi e pani ʻia ai ka paipu e ka burr i hana ʻia e ka ʻoki anu.

ʻO kekahi hemahema o nā ʻoki anu, ʻo ia ka paʻakikī e hoʻopōʻino ai i nā lau ʻoki a hiki ke hoʻokuʻi ʻia. ʻO kēlā me kēia nui o ka haʻalulu - no ka laʻana, mai ka hoʻopaʻa pono ʻole ʻana o ka ʻāpana a i ʻole ka nui o ka hānai hewa - hiki ke hōʻino maʻalahi i nā niho ʻoki. Eia kekahi, ʻo nā ʻoki anu ka mea maʻamau e hoʻolilo i ka pohō nui o kerf, kahi e unuhi ʻia ai i ka nalowale o ka hana a me nā kumukūʻai kiʻekiʻe.
ʻOiai hiki ke hoʻohana ʻia ka ʻoki anu e ʻoki ai i ka hapa nui o nā metala ferrous a me nā mea ʻole ferrous, ʻaʻole ia e ʻōlelo ʻia no nā metala paʻakikī loa - ʻoi aku hoʻi, ʻo ia hoʻi nā mea paʻakikī ma mua o ka ʻoki ponoʻī. A ʻoiai hiki i nā ʻoki anu ke hana i ka ʻoki pūʻolo, hiki iā ia ke hana pēlā me nā ʻāpana liʻiliʻi loa a pono ke hoʻopili kūikawā.

Nā Pahi Paʻakikī no ka ʻoki wikiwiki

Hoʻohana ka ʻoki anu i kahi pahi poepoe e wehe i nā mea i ka wā e hoʻoili ana i ka wela i hana ʻia i nā ʻāpana i hana ʻia e ka pahi ʻoki. Hoʻohana ka ʻoki anu i kahi pahi kila wikiwiki paʻa (HSS) a i ʻole ka pahi tungsten carbide-tipped (TCT) e hoʻohuli ana i nā RPM haʻahaʻa.
ʻAʻole like me ka inoa, ʻaʻole hoʻohana pinepine ʻia nā pahi HSS i nā wikiwiki kiʻekiʻe loa. Akā, ʻo ko lākou ʻano nui ka paʻakikī, ka mea e hāʻawi iā lākou i ke kūpaʻa kiʻekiʻe i ka wela a me ke komo ʻana. ʻOi aku ke kumukūʻai o nā pahi TCT akā paʻakikī loa hoʻi a hiki ke hana i nā mahana kiʻekiʻe aʻe ma mua o HSS. ʻAe kēia i nā pahi ʻoki TCT e hana ma nā wikiwiki wikiwiki aʻe ma mua o nā pahi HSS, e hōʻemi nui ana i ka manawa ʻoki.

ʻO ka ʻoki wikiwiki ʻana me ka ʻole o ka hoʻoulu ʻana i ka wela nui a me ka friction, kūʻē nā pahi mīkini ʻoki anu i ka ʻaʻahu mua e hiki ke hoʻopilikia i ka hoʻopau ʻana o nā ʻāpana ʻoki. Eia kekahi, hiki ke hoʻokala hou ʻia nā ʻano pahi ʻelua a hiki ke hoʻohana ʻia i nā manawa he nui ma mua o ka hoʻolei ʻia ʻana. ʻO kēia ola lōʻihi o ka pahi e kōkua i ka hana ʻana i ka ʻoki anu i mea kūpono no ka ʻoki wikiwiki a me nā hoʻopau kiʻekiʻe.

Nā hewa maʻamau e pale aku ai i ka wā e ʻoki maloʻo ai i ka metala

I kou hoʻohana ʻana i ka pahi ʻoi aku ka paʻakikī ma mua o ka metala, hiki i ka ʻoki maloʻo ke paʻakikī i kāu mau mea hana. I mea e pale aku ai i nā pohō a i ʻole nā ​​​​pōʻino i ka wā e ʻoki ana i ka metala, eia kekahi mau hewa maʻamau e makaʻala ai:

Ka Māmā o ka Pahi Kūpono ʻole: Ke ʻoki maloʻo nei ʻoe i ka metala, he mea nui e hoʻolohe i ka wikiwiki o ka pahi. Inā wikiwiki loa kāu pahi, hiki iā ia ke kūlou a pelu paha ka metala a haki i kāu pahi. Ma ka ʻaoʻao ʻē aʻe, inā e neʻe mālie loa ana, e hōʻiliʻili ka wela i loko o kāu ʻoki a hiki ke hōʻino iā ia.

Ke Kāpili Kūpono ʻole: E hōʻoia e kāpili pono i kekahi mea hao āu e ʻoki nei. He mea weliweli ka hoʻoneʻe ʻana i nā mea a hiki ke hōʻeha nui.

I ka hoʻohana ʻana i kekahi mīkini ʻoki anu, he mea nui e koho i ke kiʻekiʻe niho kūpono no ka mea e ʻoki ʻia ana.

ʻO ke koho ʻana i ke kiʻekiʻe niho kūpono no kāu pahi ʻoki anu e pili ana i:

* Ka paʻakikī o ka mea

* Ka nui o ka ʻāpana

* Mānoanoa o ka paia

Pono nā ʻāpana paʻa i nā pahi me kahi pitch niho coarse, ʻoiai ʻo nā paipu paia lahilahi a i ʻole nā ​​​​​​ʻano me nā ʻāpana keʻa liʻiliʻi e pono ai nā pahi me kahi pitch maikaʻi. Inā he nui nā niho i loko o ka mea i ka manawa hoʻokahi, ʻo ka hopena he haehae ma mua o ka wehe ʻana i nā ʻāpana. ʻO kēia ke alakaʻi i ka hoʻonui nui ʻana o ke koʻikoʻi shearing.

Ma ka ʻaoʻao ʻē aʻe, i ka wā e ʻoki ai i nā paia kaumaha a i ʻole nā ​​mea paʻa me ka hoʻohana ʻana i kahi pitch niho lahilahi loa, e wili nā ʻāpana i loko o ka ʻōpū. ʻOiai he mau ʻōpū liʻiliʻi ko nā pitch niho lahilahi, e ʻoi aku ka nui o nā ʻāpana i hōʻiliʻili ʻia ma mua o ka hiki o nā ʻōpū a kaomi i nā paia o nā ʻāpana hana e hopena ai i ka paʻa ʻana o nā ʻāpana a me ka paʻa ʻana. E hoʻomaka ka pahi ʻoki anu e hana me he mea lā ʻaʻole ia e ʻoki ana, akā no ka mea ʻaʻole hiki iā ia ke nahu me nā ʻōpū i paʻa. Inā ʻoe e koi i ka pahi ma o, e ʻike ʻoe i ka ʻoki maikaʻi ʻole a me ke kaumaha shearing koʻikoʻi, ka mea i hiki ke alakaʻi i ka haki ʻana o kāu pahi ʻoki anu.

E ʻoluʻolu e hoʻomaopopo ʻoiai he mea nui loa ke koho ʻana i ka pitch niho kūpono no kāu noi, ʻaʻole ia wale nō ke kumu e hoʻoholo ai i ka pahi ʻoki anu maikaʻi loa no kāu noi. E like me nā mea hana ʻē aʻe, ʻo ka pono a me ke ola o ka ʻoki anu e hilinaʻi nui ʻia i ka maikaʻi o nā ʻāpana koʻikoʻi e like me ka pahi. Kūʻai aku ʻo HERO i nā pahi ʻoki anu maikaʻi loa no ka mea hoʻohana mākou i nā mīkini akamai i hana ʻia e Kelemania e hana i kā mākou huahana. E kōkua kā mākou mau pahi iā ʻoe e ʻoki i ka metala no nā papahana he nui ʻole. E hauʻoli mākou e kōkua ma ke kelepona!
