Kuyerekeza Kusiyana Pakati pa Opanga Ma Saw Blade M'mayiko Osiyanasiyana

Mu gawo lopanga zinthu molondola, tsamba lozungulira la macheka amafakitale nthawi zambiri limaonedwa ngati chinthu chogwiritsidwa ntchito. Komabe, kuchokera ku lingaliro la uinjiniya, ndi chida chophatikizana chomwe chimaphatikizana ndi zitsulo, geometry, ndi makina okakamiza ziyenera kukumana.

Kwa akatswiri ogula zinthu ndi ogulitsa mafakitale, kumvetsetsa momwe zinthu padziko lonse lapansi zimagwirira ntchito popanga masamba a mphero sikutanthauza kukhulupirika kwa kampani; koma kumvetsetsa momwe zinthu zilili.ukadaulo wa m'chigawoMayiko osiyanasiyana—ndipo makamaka magulu osiyanasiyana a mafakitale m'maiko amenewo—apanga malingaliro osiyanasiyana opanga zinthu kutengera zinthu zawo zakomweko, mbiri ya mafakitale, ndi zofuna za ogwiritsa ntchito.

Lipotili likufotokoza za momwe zinthu padziko lonse lapansi zimagwirira ntchito popanga masamba a macheka, likusanthula kugawika kwa madera m'chigawo cha China, ndikuwunikanso udindo wa gulu la mafakitale ku Sichuan.

I. Magawo Okhazikika Padziko Lonse: Mafilosofi Atatu Osiyana

Msika wapamwamba kwambiri wakhala ukulamulidwa ndi madera atatu, ndipo madera onsewa akupereka nzeru zaukadaulo kumakampaniwa.

1. Germany: Ogwirizanitsa Machitidwe (Kukhazikika)Kupanga zinthu ku Germany (komwe kumaimiridwa ndi miyezo yamakampani monga Leitz kapena Leuco) sikuona tsamba la macheka ngati chida chokhachokha, koma ngati gawo la makina akuluakulu opangira.

• Kuyang'ana Kwambiri pa Uinjiniya:Chofunika kwambiri ndikukhazikikaKupyolera mu kuthwa konsekonse. Masamba a ku Germany amagogomezera ubwino wa thupi lachitsulo (mbale). Kudzera mu njira zamakono zotenthetsera ndi kupyapyala, amaonetsetsa kuti tsambalo limasunga kulekerera kwake kokhwima ngakhale litakonzedwanso.

• Khalidwe Lofunika:Kudalirika kwambiri pakupanga zinthu zokha komwe nthawi yopuma ndiyo yokwera mtengo kwambiri.

2. Italy: Akatswiri Ogwiritsa Ntchito Mapulogalamu (Kapangidwe)Opanga mipando aku Italy (monga Freud kapena Stark) achita bwino kwambiri popanga zinthu zinazake, chifukwa cha makampani akuluakulu a mipando ndi matabwa.

• Kuyang'ana Kwambiri pa Uinjiniya:Italy ikutsogolera muukadaulo wokutira(kuchepetsa kukangana ndi kusonkhana kwa utomoni) komanso mapangidwe oletsa kugwedezeka. Iwo adayambitsa ntchito yopangira "sandwich" brazing (siliva-mkuwa-siliva) kuti apewe kutayika kwa nsonga panthawi yodula mitengo yolimba.

• Khalidwe Lofunika:Kuchita bwino kwambiri pantchito yokonza matabwa ndi zitsulo zopanda chitsulo (aluminium), kuyang'ana kwambiri pa ubwino wa kumaliza.

3. Japan: Akatswiri Osamalitsa Zinthu Mwanzeru (Sayansi ya Zinthu)Kusowa kwa zinthu kunapangitsa kuti mainjiniya aku Japan (makampani monga Kanefusa kapena Tenryu) agwire bwino ntchito.

• Kuyang'ana Kwambiri pa Uinjiniya:Japan ikulamuliraKerf woondaukadaulo (kuchepetsa zinyalala) ndiCermet(ceramic-metal) metallurgy. Ukadaulo wawo wolimbitsa mphamvu ndi wapadera, zomwe zimathandiza kuti mbale zopyapyala zizungulire bwino popanda kugwedezeka.

• Khalidwe Lofunika:Kulondola kosayerekezeka pakudula zitsulo (Masawulo Ozizira) ndi zipangizo zamagetsi, ngakhale kuti nthawi zambiri kumafuna makina olondola kwambiri kuti agwire ntchito bwino.

II. Malo a ku China: Kuchokera pa Kuchuluka mpaka Kugawikana

China yadutsa gawo lokhala kampani yopereka "zida zotsika mtengo." Makampani opanga macheka aku China omwe alipo pano amatanthauzidwa ndiukadaulo wapamwamba kwambiriOpanga agawidwa m'madera enaake, ndipo madera onsewa amadalira mtundu wina wa ukadaulo wodulira.

Kuti munthu ayende bwino mu unyolo wogulitsa katundu waku China, ayenera kumvetsetsa "Mapu a Mafakitale" awa:

• Gulu la Hebei (Tangshan):Chigawochi ndi malo ofunikira kwambiri pamakampani. Chimadziwika kwambiri ndiKudula ZitsuloMafakitale pano amayang'ana kwambiri pa High-Speed ​​Steel (HSS) ndi macheka ozizira olemera a mapaipi achitsulo ndi mipiringidzo yolimba. Ukadaulo pano ndi wolimba, umayang'ana kwambiri kukana kutentha ndi kukhazikika kwa kapangidwe ka zitsulo zachitsulo.

• Gulu la Jiangsu (Danyang):Iyi ndi malo ofunikira padziko lonse lapansiZovala zowala kwambiriDanyang ndiye mtsogoleri pamsika wa masamba a diamondi opangidwa ndi sintered omwe amagwiritsidwa ntchito popanga (konkriti, granite, phula). Kupanga kuno kumachitika pogwiritsa ntchito mphamvu ya voliyumu, pogwiritsa ntchito uvuni zazikulu zoyatsira sintering.

• Gulu la East China (Hangzhou/Shanghai):Dera lino lili ndi opanga ma carbide saw blades osiyanasiyana, omwe amapereka chithandizo ku misika yonse yamatabwa ndi DIY, makamaka pa liwiro la unyolo wogulira ndi mitundu yosiyanasiyana ya zinthu.

III. Gulu la Sichuan: Malo Ogwirira Ntchito Zamatabwa Oyenera Kwambiri & PCD

Kusamukira kumtunda kupita ku Southwest China, makamaka kudera la Chengdu-Sichuan, DNA ya kupanga zinthu imasintha kwambiri.

Sichuan ndi kwawo kwaChengdu Tool Research Institute, bungwe lotsogola kwambiri la dziko lonse lofufuza zida zodulira. Kuphatikiza apo, derali ndi limodzi mwa malo akuluakulu opangira mipando ya mapanelo ku China. Kuphatikiza kumeneku kwa kafukufuku wamaphunziro ndi ogwiritsa ntchito ambiri akumaloko kwapanga gulu loyang'ana kwambiri paKukonza Matabwa MoyenerandiZipangizo Zapamwamba.

Kusiyana kwa Sichuan:Mosiyana ndi chuma cholemera cha Tangshan kapena chomwe Danyang amamanga, opanga zinthu ku Sichuan amaika patsogolo zinthu izi:

1. Ma Geometri Ovuta:Motsogozedwa ndi mabungwe ofufuza, mafakitale pano amaika patsogolo kwambiri mawonekedwe a mano (makona a zingwe, ma angles ochepetsera) kuti athetse mavuto enaake odulira.

2. PCD (Daimondi ya Polycrystalline):Popeza mipando yamakono imagwiritsa ntchito zinthu zokwawa (monga bolodi la tinthu tating'onoting'ono ndi MDF), Sichuan yakhala malo ofunikira kwambiri opangira zida za PCD. Mafakitale amenewa amagwiritsa ntchito Electrical Discharge Machining (EDM) m'malo mopera mwachizolowezi, zomwe zimathandiza kukonza zinthu zolimba kwambiri.

IV. Phunziro la Nkhani: Koocut (Sichuan)

Mkati mwa chilengedwe chapadera cha Sichuan ichi,KoocutChimaimira luso la kupanga zinthu m'derali.

Monga wopanga wokhazikika mu chikhalidwe chaukadaulo cha Sichuan, Koocut akuwonetsa momwe mafakitale aku China akukwera mtengo mwa kuyang'ana kwambiri pa zipangizo zovuta kupanga makina m'malo modula zinthu wamba.

Madera Enaake Oyenera Kuchita Bwino:

• Mayankho a Fiber Cement Board:Kudula simenti ya ulusi ndi kovuta kwambiri chifukwa cha kuchuluka kwake kokhala ndi zinthu zambiri zokwawa, zomwe zimawononga m'mbali mwa carbide mwachangu. Pogwiritsa ntchito luso la dera lino mu Polycrystalline Diamond (PCD), Koocut imapanga masamba apadera a PCD omwe adapangidwira makamaka mafakitale omanga ndi ophimba. Masamba awa amapereka nthawi yayitali yogwirira ntchito poyerekeza ndi masamba achikhalidwe a TCT, zomwe zimathandiza kuthetsa mavuto akuluakulu pantchito yomanga.

• Macheka Ozizira a Chitsulo Odulidwa Mouma:Ngakhale mafakitale ambiri aku China amapanga masamba achitsulo wamba, kugwiritsa ntchito "Dry Cut" kumafuna mulingo wapamwamba wochotsa kutentha ndi kukhazikika kwa nsonga. Koocut imagwiritsa ntchito ma Cermet tips apamwamba komanso njira zapadera zolimbitsa thupi—ukadaulo womwe nthawi zambiri umagwirizana ndi kupanga kwa Japan—kuti ipange masamba ouma odulidwa omwe amatha kudula chitsulo popanda zoziziritsira madzi. Izi zimafuna kuwongolera mwamphamvu "kuthamanga" kwa tsamba kuti lipewe kusweka kwa nsonga panthawi yogwira ntchito mwachangu komanso yotentha kwambiri.

Chidule cha Kugula

Msika wapadziko lonse wa masamba a macheka si chisankho chapadera pakati pa mitundu ya "High Quality/High Cost" ya ku Western ndi njira zina zaku Asia za "Low Quality/Low Cost".

Msika wasanduka kukhala mndandanda wa akatswiri apadera. Pa ntchito zomwe zimafuna kukhazikika kwa dongosolo, Germany ikadali muyezo. Pazolondola kwambiri, Japan ikutsogolera. Komabe, pa ntchito zapadera, zogwiritsidwa ntchito kwambiri mongasimenti ya ulusi or kudula zitsulo zouma, magulu apadera mkati mwa China—makamakaChigawo cha Sichuanakuimiridwa ndi opanga ngatiKoocut—kupereka kukhwima kwaukadaulo komwe kumatsutsana ndi miyezo yapadziko lonse lapansi, kupereka njira ina yabwino yogwirira ntchito bwino m'mafakitale.
