ʻO ka Cermet Revolution: He Luʻu hohonu i loko o ka 355mm 66T Metal Cutting Saw Blade

E ʻae mai iaʻu e pena i kahi kiʻi āu i ʻike maopopo loa ai. ʻO ka pau ʻana o kahi lā lōʻihi ma ka hale kūʻai. Ke kani nei kou mau pepeiao, ua uhi ka lepo i nā mea a pau (me loko o kou mau puka ihu), a ʻala ka ea me he metala puhi lā. Hoʻokahi hola wale nō ʻoe e ʻoki ai i ke kila no kahi papahana, a i kēia manawa ua loaʻa iā ʻoe kahi hola hou o ka wili a me ka wehe ʻana i mua ou no ka mea, ʻo kēlā me kēia ʻoki ʻoki ʻia he ʻano wela a weluwelu. No nā makahiki, ʻo ia wale nō ke kumukūʻai o ka hana ʻoihana. ʻO ka ua ʻana o nā ʻulaʻula mai kahi ʻoki abrasive ʻike ʻia ʻo ka hula ua a ka mea hana hao. Ua ʻae wale mākou. A laila, hoʻāʻo wau i kahi355mm 66T cermet ike makama kahi ʻoki anu kūpono, a e haʻi aku au iā ʻoe, he hōʻike ia. Ua like ia me ke kuai ana i ka hamare a me ke kui no ka scalpel laser. Ua loli loa ka pāʻani.

1. ʻO ka Gritty Reality: No ke aha mākou e pono ai e wehe i nā disc abrasive

No nā makahiki he nui, ʻo ia mau disc abrasive ʻeleʻele ka mea e hele ai. Akā, e hana ʻino kākou: he ala weliweli lākou e ʻoki metala. ʻAʻole lākouʻoki; ʻōniʻoniʻoni lākou i nā mea me ka hakakā. He kaʻina hana ʻino, a ʻo nā hopena ʻaoʻao nā mea a mākou i hakakā ai no ka lōʻihi loa.

1.1. ʻO kaʻu moeʻuhane abrasive disc (He huakaʻi wikiwiki i lalo i ke ala hoʻomanaʻo)

Hoʻomanaʻo wau i hoʻokahi hana kikoʻī: kahi kuʻi kuʻuna me 50 balusters kila kūpaʻa. ʻO ka waena ia o Iulai, ua wela ka hale kūʻai, a ua hoʻopaʻa ʻia au i ke kaulahao abrasive. ʻO kēlā me kēia ʻoki hoʻokahi he pilikia:

• ʻO ka hōʻike ahi:ʻO kahi huelo moa kupaianaha, akā weliweli, o nā huna ahi wela keʻokeʻo i loaʻa iaʻu ke nānā mau i nā lole ʻā. ʻO ia ka moeʻuhane ʻino loa a ka mākaʻi ahi.
• Aia ka wela:E uwa nui ana ka mea hana a ʻālohilohi maoli. ʻAʻole hiki iā ʻoe ke hoʻopā iā ia no ʻelima mau minuke me ka loaʻa ʻole o kahi kuni ʻino.
• ʻO ka Burr-den o ka hana:ʻO kēlā me kēia. hoʻokahi. ʻOki. Ua waiho ʻia kahi ʻōpala nui a ʻoi ʻoi aʻe e pono e ʻoki ʻia. ʻO kaʻu hana ʻokiʻoki 1 hola i lilo i 3 mau hola ʻoki-a-wili marathon.
• ʻO ka lāʻau hōʻemi:Hoʻomaka ka diski ma 14 iniha, akā ma hope o hoʻokahi kakini ʻoki ʻia, ua ʻike ʻia ka liʻiliʻi, e wili ana me kaʻu ʻoki hohonu a me nā hoʻonohonoho jig. Manaʻo wau ua hele au i ʻehā disc ma kēlā hana wale nō. ʻAʻole maikaʻi, pipiʻi, a pōʻino wale.

1.2. E komo i ka holoholona ʻoki anuanu: ʻo ka 355mm 66T Cermet Blade

I kēia manawa, e noʻonoʻo i kēia: ʻO kahi pahi me 66 mau niho i hana ʻia me ka pololei, ua hoʻopaʻa ʻia kēlā me kēia me kahi mea makahiki, e wili ana me ka mālie a me ka wikiwiki. ʻAʻole ia e wili; ʻako ʻo ia i ke kila e like me ka pahi wela ma ka pata. ʻO ka hopena he "ʻoki anu" - wikiwiki, hoʻomaʻemaʻe maikaʻi ʻole, ʻaneʻane ʻaʻohe ʻā a me ka wela. ʻAʻole kēia he disc abrasive ʻoi aku ka maikaʻi; he manao okoa loa no ka oki ana. ʻO nā lau cermet kūlana kiʻekiʻe ʻoihana, e like me nā ʻōlelo aʻoaʻo i hana ʻia e Iapana, hiki ke lōʻihi ma mua o ka disc abrasive ma 20-a-1. Hoʻololi ia i kāu kaʻina hana, kou palekana, a me ka maikaʻi o kāu hana.

2. Hoʻololi i ka Pepa Spec: He aha ke ʻano o "355mm 66T Cermet".

ʻO ka inoa ma ka lau ʻaʻole wale ke kālepa fluff; he papahana. E wehewehe mākou i ke ʻano o kēia mau helu a me nā huaʻōlelo iā ʻoe ma ka hale kūʻai.

2.1. Ka Anawaena o ka Blade: 355mm (Ka 14-inch Standard)

355mmʻo ia ka metric like me 14 iniha. ʻO kēia ka maʻamau o ka ʻoihana no nā ʻoki metala 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 maikaʻi loa no kekahi mea mai ka paipu kūhā 4x4 chunky a i ka paipu pā mānoanoa.

2.2. Ka helu o nā niho: No ke aha ʻo 66T ka wahi momona no ke kila

ʻO ka66The 66 niho. ʻAʻole kēia he helu maʻamau. ʻO ia ka ʻāpana Goldilocks no ka ʻoki ʻana i ke kila māmā. ʻO ka maka me ka liʻiliʻi a ʻoi aku ka ikaika o nā niho ('ōlelo ʻia, 48T) hiki ke hoʻopuka wikiwiki i ka mea akā hiki ke waiho i kahi hopena ʻoi aku ka ʻino a hopu ʻia ma kahi ʻāpana lahilahi. ʻO ka lau me ka nui o nā niho (e like me 80T+) hāʻawi i kahi hoʻopau nani akā ʻoki mālie a hiki ke hoʻopaʻa ʻia me nā ʻāpana. ʻO 66 niho ka ʻae kūpono loa, e hāʻawi ana i kahi ʻoki wikiwiki a maʻemaʻe i mākaukau e wili pololei mai ka ʻili. He kī nui hoʻi ka geometry niho—nui ka poʻe e hoʻohana ana i Modified Triple Chip Grind (M-TCG) a i ʻole like, i hoʻolālā ʻia e ʻokiʻoki i ka metala ferrous maʻemaʻe a alakaʻi i ka chip i waho o ke kerf.

2.3. ʻO ka mea kilokilo: Cermet (CERamic + METal)

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

ʻIke Pilikino: The TCT Meltdown.Ua kūʻai au i ka lau TCT maikaʻi no ka hana wikiwiki e ʻoki ana i nā papa kila he 1/4 ". Ua manaʻo wau, "Ua ʻoi aku ka maikaʻi o kēia ma mua o nā abrasives!" ʻO ia ... ma kahi o 20 mau ʻoki. 'o ia ho'i e ho'omau i kona 'o'ole'a ma kahi e ho'omaka ai ka carbide e haki i lalo.

2.4. ʻO ka Nitty-Gritty: Bore, Kerf, a me RPM

• Ka nui o ka lua:Aneane puni honua25.4mm (1 iniha). ʻO kēia ka puʻupuʻu maʻamau ma nā ʻili anu 14-inihi. E nānā i kāu ʻike, akā he pili palekana.
• Kerf:ʻO kēia ka laulā ʻokiʻoki, maʻamau he lohi2.4mm. ʻO ke kerf haiki ʻo ia hoʻi ke hoʻoheheʻe nei ʻoe i nā mea liʻiliʻi, ʻo ia hoʻi ka ʻoki wikiwiki ʻana, ka liʻiliʻi o ke koʻikoʻi ma ke kaʻa, a me ka liʻiliʻi o ka ʻōpala. He kūpono maikaʻi.
• RPM kiʻekiʻe: NUI LOA.Hoʻolālā ʻia kēia mau lau no ka haʻahaʻa haʻahaʻa, kiʻekiʻe-torque saws, me ka wikiwiki kiʻekiʻe a puni1600 RPM. Inā ʻoe e kau i kēia pahi ma kahi ʻike abrasive kiʻekiʻe (3,500+ RPM), ke hana nei ʻoe i pōkā. E ʻoi aku ka ikaika centrifugal ma mua o nā palena hoʻolālā o ka maka, e lele ana paha nā niho a nahā paha ka maka. Mai hana. Mau loa.

3. The Showdown: Cermet vs. The Old Guard

E waiho mākou i nā kikoʻī a kamaʻilio e pili ana i ka mea e hana ai ke hui ka maka i ka metala. ʻO ka ʻokoʻa ka pō a me ke ao.

3.1. Ua wehewehe ʻia ka ʻepekema o kahi "Cold Cut".

No laila, no ke aha i ʻoluʻolu ai ka metala? E pili ana i ka hoʻokumu ʻana i ka chip. Hoʻololi ka disiki abrasive i ka ikehu o kāu kaʻa i ʻāwili a me ka wela, a komo i loko o ka mea hana. ʻO ka niho cermet kahi mea hana micro-machine. ʻAhi maʻemaʻe ia i kahi ʻāpana metala. ʻO ka physics o kēia hana e hoʻoili kokoke i ka ikehu welai loko o ka chip, a laila e kipaku ʻia mai ka ʻoki. Noho maikaʻi ka mea hana a me ka lau. ʻAʻole ia he kilokilo, ʻoi aku ka naʻauao o ka ʻenekinia—ke ʻano ʻepekema waiwai a nā hui e like me ka American Welding Society (AWS) e mahalo ai, ʻoiai ʻo ia ka mea e hōʻoiaʻiʻo ʻaʻole hoʻololi ʻia nā waiwai o ka metala kumu e ka wela ma ka wahi weld.

4. Mai Ka Manaʻo a i ka Hoʻomaʻamaʻa: Lanakila ʻo Real-World

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

4.1. Ka maikaʻi ʻole: ʻO ka hopena o ka Deburring

ʻO kēia ka pōmaikaʻi āu e ʻike koke ai. Maʻemaʻe loa ka ʻoki ʻana me he mea lā ua puka mai ia mai ka mīkini wili. ʻO ia ke ʻano hiki iā ʻoe ke hele pololei mai ka ʻili a i ka papaʻaina wili. Hoʻopau ia i kahi ʻanuʻu holoʻokoʻa a me ka ʻuhane mai kāu kaʻina hana. ʻOi aku ka wikiwiki o kāu mau papahana, a ʻoi aku ka ʻoihana o kāu huahana hope.

4.2. Ka Hana Hana ma nā Steroid

ʻAʻole pili ka wikiwiki i nā ʻoki wikiwiki; ʻoi aku ka liʻiliʻi o ka manawa hoʻomaha. E noʻonoʻo: ma kahi o ka hoʻōki ʻana i ka hoʻololi ʻana i kahi disiki abrasive kahiko i kēlā me kēia ʻoki 30-40, hiki iā ʻoe ke hana no nā lā a i ʻole nā pule ma kahi pahi cermet hoʻokahi. ʻOi aku ka nui o ka manawa e loaʻa kālā a liʻiliʻi ka manawa e hoʻopili ai i kāu mau mea hana.

4.3. ʻO ka naʻauao maʻamau e hoʻoweliweli: ʻo ka ʻenehana "Variable Pressure".

Eia kekahi ʻōlelo aʻo e kūʻē i ka ʻai. ʻO ka hapa nui o nā manuals e ʻōlelo, "E hoʻopili paʻa, ʻoiai ke kaomi." A no nā mea mānoanoa, ʻaʻahu like ʻole, maikaʻi kēlā. Akā ua ʻike au he ala maikaʻi loa ia e ʻoki ai i nā niho i nā ʻoki maʻalahi.
ʻO kaʻu hopena kū'ē:I ka ʻoki ʻana i kekahi mea me kahi ʻaoʻao hoʻololi, e like me ka hao kihi, pono ʻoehuluhuluke kaomi. I kou ʻoki ʻana i ka wāwae kūwaho lahilahi, hoʻohana ʻoe i ke kaomi māmā. Ke hoʻokomo ka maka i ka wāwae ākea mānoanoa, hoʻohana ʻoe i ka ikaika. A laila, i kou haʻalele ʻana i ka ʻoki, hoʻomāmā hou ʻoe. Mālama kēia i nā niho mai ka hili ʻana i loko o ka mea ma kahi ʻaoʻao i kākoʻo ʻole ʻia, ʻo ia ke kumu #1 o ka pōʻeleʻele a i ʻole ka ʻoki ʻana. He manaʻo liʻiliʻi ia, akā e pāpālua ia i ke ola o kāu pahi. Hilinaʻi iaʻu.

5. pololei mai ka papahele hale kūʻai: pane ʻia kāu mau nīnau (N&A)

Nīnau ʻia iaʻu i kēia mau manawa a pau, no laila e hoʻomaʻemaʻe kākou i ka lewa.

Nīnau: Hiki anei iaʻu ke hoʻohana i kēia ma kaʻu ʻike ʻoki abrasive kahiko?

A: ʻAʻole loa. E haʻi hou aku au: ʻo kahi pahi cermet ma kahi 3,500 RPM abrasive saw he pōʻino pōʻino e kali ana e hiki mai. He kiʻekiʻe ka wikiwiki o ka saw, a ʻaʻohe ona torque a me ka mana pipili e pono ai. Pono ʻoe i kahi ʻoki ʻoki anuanu haʻahaʻa i hoʻolaʻa ʻia. ʻAʻohe ʻokoʻa.

Nīnau: He kiʻekiʻe kēlā kumu kūʻai mua. He waiwai maoli anei ia?

A: ʻO ia ka haʻalulu sticker, loaʻa iaʻu. Akā, e hana i ka makemakika. E ʻōlelo kākou he $150 ka maka cermet maikaʻi a he $5 ka diski abrasive. Inā hāʻawi ka cermet blade iā ʻoe i 800 ʻoki, ʻo kāu kumu kūʻai no kēlā me kēia ʻoki ma kahi o 19 keneta. Inā hāʻawi ka diski abrasive iā ʻoe i 25 ʻoki maikaʻi, ʻo kāna kumu kūʻai-no ka ʻoki ʻia he 20 keneta. A ʻaʻole ia e pili i ke kumukūʻai o kou manawa i mālama ʻia ma ka wili a me ka hoʻololi ʻana i ka lau. Uku ka cermet blade nona iho, manawa.

Nīnau: Pehea e pili ana i ka reharpening?

A: Hiki nō, akā e ʻimi i kahi loea. Pono ʻo Cermet i nā huila wili a me ka loea. ʻO kahi lawelawe ʻoki ʻike maʻamau e hana i nā ʻili lāʻau e luku paha ia. Noʻu, inā ʻaʻole wau e holo ana i kahi hale kūʻai hana nui, ʻaʻole kūpono ke kumukūʻai a me ka pilikia o ka hoʻomaʻamaʻa hou ʻana i ka hoʻohālikelike ʻia me ka lōʻihi o ke ola mua o ka lau.

Nīnau: He aha ka hewa nui a nā mea hoʻohana hou?

A: ʻElua mau mea: ʻO ka hoʻoikaika ʻana i ka ʻoki ʻana ma mua o ka waiho ʻana i ke kaumaha o ka pahi a me ka ʻoi o ka maka e hana i ka hana, a ʻaʻole e hoʻopaʻa paʻa i ka mea hana. ʻO kahi ʻāpana kila he mea pōʻino niho.

6. Ka hopena: E hooki i ka wili, E hoʻomaka i ka ʻoki

ʻO ka 355mm 66T cermet blade, i hui pū ʻia me ka ʻili ʻākau, ʻoi aku ia ma mua o kahi mea hana. He hoʻomaikaʻi kumu ia i kāu kaʻina hana metala holoʻokoʻa. Hōʻike ia i kahi kūpaʻa i ka maikaʻi, ka maikaʻi, a me kahi wahi hana palekana. Ua pau nā lā o ka ʻae ʻana i ke ʻano ahi, palaka, a pololei ʻole o ka ʻoki abrasive.

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