Kusintha kwa Cermet: Kulowera Kwambiri mu 355mm 66T Metal Cutting Saw Blade

Ndiroleni ndikufotokozereni chithunzi chomwe mukuchidziwa bwino kwambiri. Ndi kutha kwa tsiku lalitali mu shopu. Makutu anu akulira, pali fumbi labwino, lonyezimira lomwe likukuta chilichonse (kuphatikiza mkati mwa mphuno zanu), ndipo mpweya umanunkhiza ngati chitsulo chowotchedwa. Mwangothera ola limodzi mukudula zitsulo za polojekiti, ndipo tsopano muli ndi ola lina lakugaya ndi kugwetsa patsogolo panu chifukwa m'mphepete mwamtundu uliwonse ndi nyansi yotentha. Kwa zaka zambiri, zimenezo zinali chabe mtengo wochitira bizinesi. Kunyezimira kwa ntchentche za chop chop kunali kuvina kwamvula kwa wosula zitsulo. Ife tangovomereza izo. Kenako, ndinayesa a355mm 66T cermet saw tsambapa macheka oyenera odulidwa, ndipo ndiroleni ine ndikuuzeni inu, ilo linali vumbulutso. Zinali ngati kugulitsa nyundo ndi tchiseli ndi chowolera laser. Masewera anali atasinthiratu.

1. The Gritty Reality: Chifukwa Chake Tiyenera Kusiya Abrasive Discs

Kwa zaka zambiri, ma disc otsika mtengo, a bulauni anali opitako. Koma tiyeni tikhale owona mtima mwankhanza: iwo ndi njira yowopsya yodula zitsulo. Iwo saterokudula; akupera zinthu mwachiwawa ndi kupsinja. Ndi njira yankhanza, ndipo zotsatira zake ndi zinthu zomwe takhala tikulimbana nazo kwa nthawi yayitali kwambiri.

1.1. My Abrasive Disc Nightmare (A Quick Trip Down Memory Lane)

Ndikukumbukira ntchito ina yapadera: njanji yokhazikika yokhala ndi zitsulo zopindika 50. Panali pakati pa mwezi wa July, sitoloyo inali ikusefukira, ndipo ndinamangidwa ndi macheka abrasive. Kudula kulikonse kunali kovutirapo:

• Chiwonetsero cha Moto:Mchira wa tambala wochititsa chidwi, koma wochititsa mantha, wakunyezimira koyera komwe kanandichititsa kuyang'anitsitsa nsanza zofuka. Ndilo loto loyipa kwambiri la ozimitsa moto.
• Kutentha Kwayaka:Chogwiritsira ntchito chimayamba kukuwa kwambiri moti chimawala kwambiri. Simungathe kuchigwira kwa mphindi zisanu osapsa ndi moto woyipa.
• Ufulu wa ntchito:Aliyense. Wokwatiwa. Dulani. Anasiya chiboliboli chachikulu, chakuthwa ngati lumo chomwe chinayenera kudulidwa. Ntchito yanga yodulira ya ola limodzi inasanduka mpikisano wa maola atatu wodula ndi kupera.
• The Shrinking Blade:Chimbalecho chinayambira pa mainchesi 14, koma nditadulidwa kangapo, chinali chocheperako, ndikumangirira ndikudula kwanga ndi ma jig setups. Ndikuganiza kuti ndinadutsa ma disks anayi pa ntchitoyo ndekha. Zinali zosathandiza, zodula, komanso zomvetsa chisoni.

1.2. Lowani Chilombo Chozizira: Tsamba la Cermet 355mm 66T

Tsopano jambulani chithunzi ichi: Tsamba lomwe lili ndi mano 66 opangidwa molondola kwambiri, lililonse lokhala ndi nsonga yotalikirapo, likuzungulira mwakachetechete, komanso liŵiro lolamulirika. Sizikupera; umameta chitsulo ngati mpeni wotentha mu batala. Chotsatira chake ndi “kuzizira”—mwachangu, mwaukhondo mochititsa kaso, wopanda pafupifupi zopsereza kapena kutentha. Izi si bwino abrasive chimbale; ndi nzeru yosiyana kotheratu ya kudula. Ma cermet grade aukadaulo, monga omwe ali ndi malangizo opangidwa ku Japan, amatha kupitilira chimbale cha abrasive pofika 20-to-1. Zimasintha kayendedwe ka ntchito, chitetezo chanu, ndi mtundu wa ntchito yanu.

2.2. Kuwerengera Mano: Chifukwa chiyani 66T ndi Malo Otsekemera a Zitsulo

The66T ndiimayimira 66 mano. Iyi si nambala yachisawawa. Ndilo gawo la Goldilocks podula zitsulo zofatsa. Tsamba lomwe lili ndi mano ochepa, aukali kwambiri (titi, 48T) limatha kutulutsa zinthu mwachangu koma limatha kutha movutikira ndikugwira ntchito yopyapyala. Tsamba lomwe lili ndi mano ochulukirapo (monga 80T+) limapereka kumaliza kokongola koma limadula pang'onopang'ono ndipo limatha kutsekedwa ndi tchipisi. Mano 66 ndiye kunyengerera kwabwino, kupereka mwachangu, kudula koyera komwe kuli kokonzeka kuwotcherera pa macheka. Jiometry ya dzino ndiyonso yofunika kwambiri—ambiri amagwiritsa ntchito Modified Triple Chip Grind (M-TCG) kapena yofananira, yopangidwa kuti azidula zitsulo zoyera bwino ndikuwongolera chip kuchokera mu kerf.

2.3. Zosakaniza Zamatsenga: Cermet (CERamic + METal)

Uwu ndiye msuzi wachinsinsi.Cermetndi chinthu chophatikizika chomwe chimaphatikiza kukana kutentha kwa ceramic ndi kulimba kwachitsulo. Izi ndizosiyana kwambiri ndi masamba wamba a Tungsten Carbide Tipped (TCT).

Kudzipeza Kwawekha: Kuwonongeka kwa TCT.Nthawi ina ndinagula tsamba la TCT lapamwamba kwambiri chifukwa cha ntchito yofulumira kudula mbale zazitsulo za 1/4. Ndinaganiza kuti, "Izi ndi zabwino kuposa abrasives!" Zinali ... kwa mabala a 20. Kenaka ntchito inatsikira pamtunda. Kutentha kwakukulu komwe kunapangidwa pamene kudula zitsulo kunachititsa kuti nsonga za carbide zivutike ndi kutenthedwa kwa kutentha, micro-fracturing pa dzanja lina, kuseka ndi kutentha. Makhalidwe ake a ceramic amatanthawuza kuti amasunga kuuma kwake pa kutentha komwe carbide imayamba kusweka.

2.4. The Nitty-Gritty: Bore, Kerf, ndi RPM

• Kukula kwa Bore:Pafupifupi konsekonse25.4mm (1 inchi). Uwu ndiye malo okhazikika pa macheka ozizira 14-inch. Yang'anani macheka anu, koma ndi kubetcha kotetezeka.
• Kerf:Uwu ndiye m'lifupi mwake, wocheperako2.4 mm. Kerf yopapatiza imatanthawuza kuti mukupanga nthunzi pang'ono, zomwe zimatanthawuza kudulidwa mwachangu, kuchulukirachulukira pagalimoto, komanso kutaya pang'ono. Ndi koyera dzuwa.
• Zambiri RPM: ZOFUNIKA KWAMBIRI.Masambawa amapangidwira macheka othamanga kwambiri, othamanga kwambiri, othamanga kwambiri1600 rpm. Mukayika tsamba ili pa macheka othamanga kwambiri (3,500+ RPM), mukupanga bomba. Mphamvu yapakati imadutsa malire a momwe tsambalo limapangidwira, zomwe zimapangitsa kuti mano aziuluka kapena kusweka. Musati muchite izo. Nthawi zonse.

3. Chiwonetsero: Cermet vs. Old Guard

Tiyeni tiyike pambali ndi kukambirana zomwe zimachitika pamene tsamba lakumana ndi zitsulo. Kusiyana kwake ndi usiku ndi usana.

3.1. Sayansi ya "Cold Cut" Yafotokozedwa

Ndiye n'chifukwa chiyani zitsulo zili bwino? Zonse ndi kupanga chip. Dongosolo la abrasive disc limasintha mphamvu ya mota yanu kukhala mikangano ndi kutentha, komwe kumalowa muzogwirira ntchito. Dzino la cermet ndi chida cha micro-makina. Amameta bwino chitsulo. Fiziki ya izi imasamutsa pafupifupi mphamvu zonse zotenthamu chip, yomwe kenako imatulutsidwa kutali ndi kudula. Chovala chogwirira ntchito ndi tsamba zimakhala zozizira kwambiri. Simatsenga, ndi uinjiniya wanzeru-mtundu wa sayansi yazinthu zomwe mabungwe monga American Welding Society (AWS) amayamikira, chifukwa zimatsimikizira kuti zitsulo zoyambira sizisinthidwa ndi kutentha pamalo owotcherera.

4. Kuchokera ku Chiphunzitso mpaka Kuchita: Dziko lenileni Limapambana

Ubwino womwe uli patsamba laling'ono ndi wabwino, koma chofunikira ndi momwe zimasinthira ntchito yanu. Apa ndi pomwe mphira umakumana ndi msewu.

4.1. Ubwino Wosayerekezeka: Mapeto a Deburring

Uwu ndiye phindu lomwe mumamva nthawi yomweyo. Chodulidwacho ndi choyera kwambiri chikuwoneka ngati chinachokera pamakina ogaya. Izi zikutanthauza kuti mutha kupita molunjika kuchokera ku macheka kupita ku tebulo lowotcherera. Zimachotsa gawo lathunthu, losweka mtima pakupanga kwanu. Ntchito zanu zimachitika mwachangu, ndipo malonda anu omaliza amawoneka ngati akatswiri.

4.2. Kuchita bwino kwa Workshop pa Steroids

Kuthamanga sikungokhudza kudula mwachangu; ndi pafupi nthawi yochepa. Ganizirani izi: m'malo mosiya kusintha chimbale chowonongeka cha abrasive 30-40 mabala aliwonse, mukhoza kugwira ntchito kwa masiku kapena masabata pa tsamba limodzi la cermet. Ndiko kupanga ndalama zambiri komanso kumachepetsa nthawi yocheza ndi zida zanu.

4.3. Kutsutsa Nzeru Wamba: Njira ya "Variable Pressure".

Nawa malangizo otsutsana ndi njere. Mabuku ambiri amati, "Ikani mosasunthika, ngakhale kukakamiza." Ndipo pazinthu zokhuthala, zofananira, ndizabwino. Koma ndapeza kuti iyi ndi njira yabwino kwambiri yotchinjiriza mano pamabala ovuta kwambiri.
Yankho Langa la Contrarian:Mukamadula chinthu chokhala ndi mawonekedwe osinthika, ngati ngodya yachitsulo, muyenera kuteronthengakupsyinjika. Pamene mukudula mwendo wowonda wowonda, mumagwiritsa ntchito mphamvu yopepuka. Pamene tsambalo limagwira mwendo wopingasa wokhuthala, mumagwiritsa ntchito mphamvu zambiri. Ndiye, pamene mukutuluka mdulidwewo, mumapepukanso. Izi zimalepheretsa mano kuti asagwedezeke m'mphepete mwachitsulo, chomwe ndi chifukwa # 1 chomwe chimachititsa kuti musachedwe kapena kuphwanyidwa. Zimatengera pang'ono kumva, koma zidzawonjezera moyo wa tsamba lanu. Ndikhulupirire.

5. Molunjika kuchokera Pansi Pansipa: Mafunso Anu Akuyankhidwa (Q&A)

Ndimafunsidwa nthawi zonse, ndiye tiyeni tifufuze.

Q: Kodi ndingatani, sindingagwiritse ntchito izi pa macheka anga akale a abrasive chop?

A: Ayi ndithu. Ndikunenanso: tsamba la cermet pa 3,500 RPM abrasive saw ndi kulephera koopsa komwe kukuyembekezera kuchitika. Liwiro la macheka ndi lokwera kwambiri, ndipo ilibe torque ndi mphamvu yotchingira yofunika. Mufunika macheka odulidwa othamanga kwambiri, othamanga kwambiri. Palibe kuchotserapo.

Q: Mtengo woyambawo ndi wokwera. Kodi m'pofunikadi?

A: Ndi kugwedezeka kwa zomata, ndikumvetsa. Koma chitani masamu. Tinene kuti tsamba labwino la cermet ndi $150 ndipo chimbale cha abrasive ndi $5. Ngati tsamba la cermet limakupatsani mabala 800, mtengo wanu wodula ndi pafupifupi masenti 19. Ngati abrasive disc imakupatsani mabala 25 abwino, mtengo wake podula ndi masenti 20. Ndipo izi sizimatengera mtengo wa nthawi yanu yosungidwa pakupera ndi kusintha kwa tsamba. Tsamba la cermet limadzilipira lokha, nthawi.

Q: Nanga bwanji kukonzanso?

A: Ndizotheka, koma pezani katswiri. Cermet imafuna mawilo apadera okupera ndi ukatswiri. Utumiki wonola wanthawi zonse womwe umapanga matabwa ukhoza kuwononga. Kwa ine, pokhapokha nditakhala ndi shopu yayikulu yopangira zinthu, mtengo wake komanso zovuta zakukonzanso nthawi zambiri sizoyenera kuyerekeza ndi moyo wautali wa tsambalo.

Q: Kodi cholakwika chachikulu ndi chiyani chomwe ogwiritsa ntchito atsopano amapanga?

Yankho: Zinthu ziwiri: Kukakamiza kudula m'malo molola kulemera kwa macheka ndi kuthwa kwa tsamba kuti zigwire ntchitoyo, osati kumangirira chogwiriracho mosamala. Chitsulo chogwedezeka ndi loto lopweteka kwambiri.

6. Kutsiliza: Lekani Kugaya, Yambani Kudula

Tsamba la cermet la 355mm 66T, lophatikizidwa ndi macheka olondola, silili chida chabe. Ndiko kukweza kofunikira pakupanga zitsulo zonse. Zimayimira kudzipereka kuzinthu zabwino, zogwira mtima, ndi malo otetezeka ogwira ntchito. Masiku ovomereza zaukali, zosokoneza, ndi zosalongosoka za kudula kwa abrasive atha.

Kupanga kusinthaku kumafuna ndalama zoyambira, koma kubweza-panthawi yopulumutsidwa, ntchito yopulumutsidwa, zida zosungidwa, komanso chisangalalo chodulira bwino-ndichosawerengeka. Ndi chimodzi mwazinthu zanzeru zomwe wosula zitsulo wamakono angapange. Chifukwa chake dzichitireni zabwino: gwiritsitsani chopukusira, yambitsani ukadaulo woyenera, ndikupeza zomwe zimamveka ngati kugwira ntchito mwanzeru, osati movutikira. Simudzayang'ana konse mmbuyo.
