ʻO ka Cermet Revolution: He Luʻu Hohonu i loko o ka Blade ʻokiʻoki metala 355mm 66T

E ʻae mai iaʻu e pena iā ʻoe i kahi kiʻi āu i ʻike maikaʻi ai. ʻO ka hopena kēia o kahi lā lōʻihi ma ka hale kūʻai. Ke kani nei kou mau pepeiao, aia kahi lepo maikaʻi a ʻōpala e uhi ana i nā mea āpau (me loko o kou mau ihu), a ke ʻala nei ka ea e like me ka metala i puhi ʻia. Ua hoʻolilo wale ʻoe i hoʻokahi hola e ʻoki ana i ke kila no kahi papahana, a i kēia manawa he hola hou kāu o ka wili ʻana a me ka wehe ʻana i nā ʻōpala i mua ou no ka mea he wela a ʻōpala kēlā me kēia ʻaoʻao ʻoki. No nā makahiki, ʻo ia wale nō ke kumukūʻai o ka hana ʻoihana. ʻO ka ua o nā huna ahi mai kahi ʻoki ʻoki abrasive ka hula ua a ka mea hana hao. Ua ʻae wale mākou. A laila, ua hoʻāʻo wau i kahiʻO ka pahi ʻoki cermet 355mm 66Tma kahi ʻoki anu kūpono, a e ʻae mai iaʻu e haʻi aku iā ʻoe, he mea hōʻike ia. Ua like ia me ke kūʻai ʻana i ka hāmare a me ke kālai no kahi scalpel laser. Ua loli loa ka pāʻani.

1. ʻO ka ʻoiaʻiʻo Gritty: No ke aha e pono ai mākou e hoʻolei i nā discs Abrasive

No nā makahiki he ʻumi, ʻo kēlā mau disc abrasive ʻeleʻele makepono ke kumu kūʻai. Akā e ʻoiaʻiʻo kākou: he ala weliweli lākou e ʻoki ai i ka metala. ʻAʻole lākouʻoki; wili ikaika lākou i nā mea ma o ka friction. He hana ikaika ia, a ʻo nā hopena ʻaoʻao he mau mea a mākou i hakakā ai no ka manawa lōʻihi loa.

1.1. Kaʻu Moeʻuhane ʻino o ka Disc Abrasive (He Huakaʻi Wikiwiki ma ke Ala Hoʻomanaʻo)

Hoʻomanaʻo wau i hoʻokahi hana kikoʻī: he pale hana maʻamau me 50 mau pale kila kū pololei. ʻO ka waena ia o Iulai, ua wela loa ka hale kūʻai, a ua hoʻopaʻa ʻia au i ke kaulahao i ka ʻoki ʻoki. He hoʻāʻo nui kēlā me kēia ʻoki:

• ʻO ka Hōʻikeʻike Ahi:He huelo moa kupaianaha, akā weliweli, o nā huna ahi wela keʻokeʻo i hoʻoikaika mau iaʻu e nānā i nā ʻōpala e ʻā ana. He moeʻuhane ʻino loa ia no ka luna ahi.
• Ke Wela Nei:E wela loa ana ka mea hana a e ʻālohilohi maoli i ka uliuli. ʻAʻole hiki iā ʻoe ke hoʻopā aku no ʻelima mau minuke me ka loaʻa ʻole o kahi kuni ʻino.
• ʻO ka Burr-den o ka Hana:Kēlā me kēia. Hoʻokahi. ʻOki. Ua waiho i kahi ʻū nui a ʻoi loa e pono ai ke wili ʻia. Ua lilo kaʻu hana ʻoki 1 hola i marathon ʻoki-a-wili 3 hola.
• ʻO ka Pahi Hoʻēmi:Ua hoʻomaka ka diski ma 14 ʻīniha, akā ma hope o nā ʻoki he ʻumikūmālua, ua ʻike ʻia ka liʻiliʻi, e kūlike ana me ka hohonu o kaʻu ʻoki a me nā hoʻonohonoho jig. Manaʻo wau ua hana au i ʻehā mau diski ma ia hana wale nō. He hana ʻole ia, he pipiʻi, a he mea ʻino wale nō.

1.2. E komo i ka holoholona ʻoki anu: ʻO ka pahi Cermet 355mm 66T

I kēia manawa, e noʻonoʻo i kēia: He pahi me 66 mau niho i hana ʻia me ka pololei, kēlā me kēia me kahi mea o ka wā lewa, e milo ana i ka wikiwiki mālie a kāohi ʻia. ʻAʻole ia e wili; ʻoki ia i ke kila e like me ka pahi wela i loko o ka pata. ʻO ka hopena he "ʻoki anu" - wikiwiki, maʻemaʻe kupaianaha, me ka aneane ʻole o nā huna ahi a wela paha. ʻAʻole kēia he disc abrasive ʻoi aku ka maikaʻi; he ʻano ʻokoʻa loa ia o ka ʻoki ʻana. ʻO nā pahi cermet ʻoihana, e like me nā mea me nā wēlau i hana ʻia e Iapana, hiki ke ola ma mua o kahi disc abrasive ma 20-a-1. Hoʻololi ia i kāu kahe hana, kou palekana, a me ke ʻano o kāu hana.

2. Wehewehe ʻana i ka Pepa Kikoʻī: He aha ka manaʻo maoli o "355mm 66T Cermet"

ʻAʻole wale ka inoa ma ka pahi he mea hoʻolaha lapuwale; he palapala hoʻolālā ia. E wehewehe kākou i ke ʻano o kēia mau helu a me nā huaʻōlelo iā ʻoe ma ka hale kūʻai.

2.1. Anawaena o ka Pahi: 355mm (ʻO ke Kūlana 14-'īniha)

355mmʻo ia wale nō ka metric like o 14 ʻīniha. ʻO kēia ke kūlana ʻoihana no nā ʻoki hao piha piha, ʻo ia hoʻi, ua hoʻolālā ʻia e kūpono i nā mīkini āu e hoʻohana ai, e like me ka Evolution S355CPS a i ʻole Makita LC1440. Hāʻawi kēia nui iā ʻoe i kahi mana ʻoki kupaianaha no nā mea āpau mai ka paipu huinaha 4x4 chunky a i ka paipu paia mānoanoa.

2.2. Helu Niho: No ke aha ʻo 66T ka wahi kūpono no ke kila

ʻO ka66TʻO ke kū nei no 66 mau niho. ʻAʻole kēia he helu kaulele. ʻO ia ka ʻāpana Goldilocks no ka ʻoki ʻana i ke kila palupalu. ʻO ka pahi me nā niho ʻoi aku ka liʻiliʻi a ʻoi aku ka ikaika (e ʻōlelo, 48T) e hopu wikiwiki i ka mea akā hiki ke waiho i kahi ʻoi aku ka paʻakikī a paʻa i ka waihona lahilahi. ʻO ka pahi me nā niho he nui (e like me 80T+) e hāʻawi i kahi ʻano nani akā ʻoki lohi a hiki ke paʻa me nā ʻāpana. ʻO 66 mau niho ka ʻaelike kūpono, e hāʻawi ana i kahi ʻoki wikiwiki a maʻemaʻe e mākaukau e hoʻopili pololei mai ka ʻoki. He mea nui nō hoʻi ke ʻano o ka niho—hoʻohana ka poʻe he nui i ka Modified Triple Chip Grind (M-TCG) a i ʻole nā ​​mea like, i hoʻolālā ʻia e ʻoki maʻemaʻe i ka metala ferrous a alakaʻi i ka ʻāpana mai ke kerf.

2.3. Ka Mea Hana Kilokilo: Cermet (CERamic + METal)

ʻO kēia ka mea ʻala huna.ʻO Cermethe mea i hui pū ʻia e hoʻohui i ke kūpaʻa wela o ka seramika me ka paʻakikī o ka metala. He ʻokoʻa koʻikoʻi kēia mai nā pahi Tungsten Carbide Tipped (TCT) maʻamau.

ʻIke Pilikino: Ka TCT Meltdown.Ua kūʻai au i kekahi manawa i kahi pahi TCT kiʻekiʻe no ka hana wikiwiki e ʻoki ana i nā ʻumi o nā papa kila 1/4". Ua manaʻo wau, "ʻOi aku ka maikaʻi o kēia ma mua o nā mea abrasives!" ʻO ia... no kahi o 20 mau ʻoki. A laila hāʻule ka hana mai kahi pali. ʻO ka wela nui i hana ʻia i ka wā e ʻoki ana i ke kila ua hoʻopilikia i nā wēlau carbide i ka haʻalulu wela, micro-fracturing a me ka palalulu ʻana i ka lihi. ʻO Cermet, ma ka ʻaoʻao ʻē aʻe, ʻakaʻaka wale i kēlā wela. ʻO kona mau waiwai seramika ke ʻano o ia mea e mālama i kona paʻakikī i nā mahana kahi e hoʻomaka ai ka carbide e haki. ʻO ia ke kumu e ola ai ka pahi cermet ma mua o ka pahi TCT i nā manawa he nui i kahi noi ʻoki kila. Ua kūkulu ʻia no ka hana ʻino.

2.4. ʻO ke kikoʻī: Bore, Kerf, a me RPM

• Ka nui o ka lua:Kokoke i nā wahi āpau25.4mm (1 ʻīniha)ʻO kēia ke arbor maʻamau ma nā ʻoki anu 14-'īniha. E nānā i kāu ʻoki, akā he koho palekana ia.
• Kerf:ʻO kēia ka laulā o ka ʻoki, he lahilahi maʻamau2.4mmʻO ke kerf haiki ke ʻano o ka hoʻomake ʻana i nā mea liʻiliʻi, ʻo ia hoʻi ka ʻoki wikiwiki ʻana, ka emi ʻana o ke kaumaha ma ka motika, a me ka liʻiliʻi o ka hoʻonele ʻana. He pono maoli nō ia.
• RPM kiʻekiʻe loa: HE MEA KOʻIKOʻI LOA.Ua hoʻolālā ʻia kēia mau pahi no nā ʻoki wikiwiki haʻahaʻa, kiʻekiʻe-torque, me ka wikiwiki max a puni1600 RPMInā ʻoe e kau i kēia pahi ma luna o kahi ʻoki ʻoki wikiwiki (3,500+ RPM), ke hana nei ʻoe i kahi pōkā. E ʻoi aku ka ikaika centrifugal ma mua o nā palena hoʻolālā o ka pahi, e hoʻokuke ana paha i nā niho a haki paha ka pahi. Mai hana pēlā. ʻAʻole loa.

3. Ka Hōʻikeʻike: Cermet vs. The Old Guard

E waiho kākou i nā kikoʻī a kamaʻilio e pili ana i ka mea e hana ʻia ke hui ka pahi me ka metala. ʻO ka ʻokoʻa ka pō a me ke ao.

3.1. Ua wehewehe ʻia ka ʻepekema o kahi "ʻoki anu"

No ke aha i anuanu ai ka metala? Pili ia i ka hoʻokumu ʻana o nā ʻāpana. Hoʻololi kahi diski abrasive i ka ikehu o kāu motika i ka friction a me ka wela, kahi e komo ai i loko o ka workpiece. He mea hana micro-mīkini ka niho cermet. Hoʻomaʻemaʻe ia i kahi ʻāpana metala. Hoʻoili ka physics o kēia hana i ka ikehu wela āpau.i loko o ka ʻāpana, a laila e kipaku ʻia aku mai ka ʻoki. Noho anuanu loa ka ʻāpana hana a me ka pahi. ʻAʻole ia he hana kilokilo, he ʻenekinia akamai wale nō—ke ʻano ʻepekema mea e mahalo nui ʻia e nā ʻoihana e like me ka American Welding Society (AWS), no ka mea, e hōʻoiaʻiʻo ana ʻaʻole i hoʻololi ʻia nā waiwai o ka metala kumu e ka wela ma ka ʻāpana weld.

4. Mai ke Kumumanaʻo a i ka Hana: Nā Lanakila o ke Ao Maoli

He maikaʻi nā pono ma kahi pepa kikoʻī, akā ʻo ka mea nui pehea e hoʻololi ai i kāu hana. Eia kahi e hui ai ka laholio me ke alanui.

4.1. ʻAno Kūlike ʻole: Ka Hopena o ka Deburring

ʻO kēia ka pōmaikaʻi āu e ʻike koke ai. Ua maʻemaʻe loa ka ʻoki a me he mea lā ua puka mai ia mai kahi mīkini wili. ʻO ia hoʻi, hiki iā ʻoe ke hele pololei mai ka ʻoki a i ka papa wili. Hoʻopau ia i kahi ʻanuʻu holoʻokoʻa e hoʻoluhi ana i ka ʻuhane mai kāu kaʻina hana. Hoʻopau wikiwiki ʻia kāu mau papahana, a ʻoi aku ka ʻoihana o kāu huahana hope loa.

4.2. Ka pono o ka hana ma nā Steroids

ʻAʻole wale ka wikiwiki e pili ana i nā ʻoki wikiwiki; e pili ana i ka emi ʻana o ka manawa hoʻomaha. E noʻonoʻo e pili ana i ia mea: ma kahi o ka hoʻōki ʻana e hoʻololi i kahi disc abrasive i pau i kēlā me kēia 30-40 ʻoki, hiki iā ʻoe ke hana no nā lā a i ʻole nā ​​pule ma kahi pahi cermet hoʻokahi. ʻO ia ka manawa hou aku e loaʻa kālā ai a me ka manawa liʻiliʻi e hoʻoponopono ai i kāu mau mea hana.

4.3. Hoʻokūkū i ka Naʻauao Maʻamau: Ke ʻAno Hana "Pāomi Hoʻololi"

Eia kahi ʻōlelo aʻoaʻo e kūʻē i ke ʻano. ʻŌlelo ka hapa nui o nā manual, "E kau i ke kaomi paʻa a like." A no ka mea mānoanoa a like, ua maikaʻi kēlā. Akā ua ʻike au he ala maikaʻi loa ia e ʻoki ai i nā niho ma nā ʻoki paʻakikī.
Kaʻu Hoʻonā Kū'ē:I ke ʻoki ʻana i kahi mea me kahi ʻano loli, e like me ka hao kihi, pono ʻoehulu manuke kaomi. Ke ʻoki ʻoe i ka wāwae kū pololei lahilahi, hoʻohana ʻoe i ke kaomi māmā. Ke hoʻopili ka pahi i ka wāwae ākea mānoanoa, hoʻopili ʻoe i ka ikaika hou aku. A laila, ke puka ʻoe i waho o ka ʻoki, hoʻomālamalama hou ʻoe. Pale kēia i nā niho mai ke kuʻi ʻana i loko o ka mea ma kahi lihi i kākoʻo ʻole ʻia, ʻo ia ke kumu #1 o ka palalulu mua ʻana a i ʻole ka chipping. Pono ia i kahi manaʻo iki, akā e pāpālua ia i ke ola o kāu pahi. E hilinaʻi mai iaʻu.

5. Pololei mai ka Papa Hale Kūʻai: Ua Pane ʻia kāu mau Nīnau (Q&A)

Ua nīnau pinepine ʻia mai iaʻu kēia mau mea, no laila e hoʻomālamalama kākou i ka ʻino.

Q: Hiki iaʻu ke hoʻohana maoli ʻole i kēia ma kaʻu ʻoki ʻoki abrasive kahiko?

A: ʻAʻole loa. E ʻōlelo hou wau: he hemahema weliweli ka pahi cermet ma kahi ʻoki abrasive 3,500 RPM e kali ana e hana. He kiʻekiʻe loa ka wikiwiki o ka ʻoki, a nele ia i ka torque a me ka mana clamping e pono ai. Pono ʻoe i kahi ʻoki anu haʻahaʻa wikiwiki, kiʻekiʻe-torque. ʻAʻohe ʻokoʻa.

Q: Kiʻekiʻe loa kēlā kumukūʻai mua. He waiwai maoli anei ia?

A: He mea hoʻohoka ia no ka sticker, maopopo iaʻu. Akā e hana i ka makemakika. E ʻōlelo kākou he $150 ke kumukūʻai o kahi pahi cermet maikaʻi a he $5 ke kumukūʻai o kahi disc abrasive. Inā hāʻawi ka pahi cermet iā ʻoe i 800 mau ʻoki, ʻo kāu kumukūʻai no kēlā me kēia ʻoki he 19 keneta. Inā hāʻawi ka disc abrasive iā ʻoe i 25 mau ʻoki maikaʻi, ʻo kona kumukūʻai no kēlā me kēia ʻoki he 20 keneta. ʻAʻole ia e pili ana i ke kumukūʻai o kou manawa i mālama ʻia ma ka wili ʻana a me ka hoʻololi ʻana i ka pahi. Uku ka pahi cermet nona iho, manawa.

Q: Pehea e pili ana i ka hoʻokala hou ʻana?

A: Hiki nō, akā e ʻimi i kahi loea. Pono ʻo Cermet i nā huila wili kūikawā a me ka ʻike loea. ʻO kahi lawelawe wili lāʻau maʻamau e hana ana i nā pahi lāʻau e hoʻopau paha iā ia. Noʻu, ke ʻole wau e holo nei i kahi hale hana nui, ʻaʻole kūpono ke kumukūʻai a me ka pilikia o ka wili hou ʻana i ka hoʻohālikelike ʻia me ke ola lōʻihi o ka pahi i ka wā mua.

Q: He aha ka hewa nui a nā mea hoʻohana hou e hana ai?

A: ʻElua mau mea: Ke koi ʻana i ka ʻoki ma kahi o ka ʻae ʻana i ke kaumaha o ka ʻoki a me ka ʻoi o ka pahi e hana i ka hana, a ʻaʻole e hoʻopaʻa pono i ka mea hana. He moeʻuhane ʻino ka ʻāpana kila e nahā ana.

6. Hopena: Hoʻōki i ka wili ʻana, hoʻomaka i ka ʻoki ʻana

ʻO ka pahi cermet 355mm 66T, i hui pū ʻia me ka ʻoki ʻākau, ʻoi aku ia ma mua o kahi mea hana wale nō. He hoʻonui koʻikoʻi ia i kāu kaʻina hana metala holoʻokoʻa. Hōʻike ia i ka kūpaʻa i ka maikaʻi, ka pono, a me kahi ʻano hana palekana. Ua pau nā lā o ka ʻae ʻana i ke ʻano wela, haunaele, a me ke ʻano pololei ʻole o ka ʻoki ʻana i ka abrasive.

ʻO ka hana ʻana i ke kuapo e pono ai kahi hoʻopukapuka mua, akā ʻo ka hoʻihoʻi - i ka manawa i mālama ʻia, ka hana i mālama ʻia, nā mea i mālama ʻia, a me ka hauʻoli nui o ka ʻoki kūpono - ʻaʻole hiki ke ana ʻia. ʻO ia kekahi o nā hoʻomaikaʻi akamai loa e hiki i kahi mea hana hao hou ke hana. No laila e hana iā ʻoe iho i kahi lokomaikaʻi: e kau i ka wili abrasive, e hoʻopukapuka i ka ʻenehana kūpono, a e ʻike i ke ʻano o ka hana akamai, ʻaʻole paʻakikī. ʻAʻole ʻoe e nānā i hope.
