Munyika yekushanda kwesimbi mumaindasitiri, simbi isingatsvi inozivikanwa nekuoma kwayo kwakanyanya. Ungave uchishanda ne304, 316, kana 400-series alloys dzakagadzirwa, zvinhu izvi zvinogadzira dambudziko guru kune zvishandiso zvekucheka zvakajairwa: kupisa kwakanyanya, kuri munzvimbo imwe chete.

KuJiacheng Tools, timu yedu yehunyanzvi inowanzo tsanangura kuti sei mabhiti esimbi anomhanyisa kumhanya (HSS) achikundikana nguva isati yakwana pakuchera simbi isingatsvi. Mhinduro iri muhunhu hwekupisa hwechinhu ichi, uye mhinduro yakavimbika ndeyekushandisa mabhiti ekuboorera eCobalt (HSS-Co).

Sainzi yekupisa musimbi isina ngura

Simbi isina ngura ine thermal conductivity yakaderera. Paunoboora mukati mayo, kupisa kunokonzerwa nekucheka hakuperi nepabasa kana kubuda nemachipisi. Pane kudaro, kupisa kunoramba kwakabatana chaizvo panosangana drill bit nesimbi.

Zvidimbu zveHSS zvakajairika zvinowanzotanga kupfava uye kurasikirwa nemucheto wazvo wakapinza kana tembiricha yasvika pa500°C. Sezvo chidimbu chacho chisisina kusimba, chinotanga kukwesha pane kucheka, izvo zvinogadzira kukweshana kwakanyanya uye kupisa. Izvi zvinokurumidza kukonzera kuti "tip" itsve, drill bit iparare, uye workpiece ikuvara.

Chakavanzika che "Kuoma Kwakatsvuka"

Zvidimbu zvekuboorera zveCobalt—kunyanya izvo zvakagadzirwa neM35 (5% Cobalt) kana M42 (8% Cobalt) alloys—zvakagadzirwa kuti zvibudirire munzvimbo idzi dzinopisa zvakanyanya.

Chinhu chakakosha zvikuru paCobalt ndechekuti "Red Hardness." Uku ndiko kugona kwechinhu chekucheka kuchengetedza chimiro chayo chakasimba uye mucheto wakapinza kunyangwe chishandiso chacho chichipenya zvakanyanya (kusvika 600°C - 700°C). Kunyange hazvo simbi yakajairwa ichinyorovesa (kupfava) padanho iri, Cobalt alloys dzinoramba dzakasimba uye dzichiramba dzichicheka zvakanaka.

M35 vs M42: Ndeipi Yaunoda?

Kuti usarudze chishandiso chakakodzera purojekiti yako, zvinobatsira kunzwisisa magiredhi maviri makuru anoshandiswa mukugadzira zvinhu zvehunyanzvi:

●M35 (5% Cobalt): Iyi ndiyo "yakazara" yesimbi isingatsvi. Inopa chiyero chakanaka chekudzivirira kupisa uye kusimba, zvichiita kuti isanyanya kuputsika kupfuura cobalt grades yakakwira. Ndiyo sarudzo inosarudzwa pamabasa mazhinji ekugadzirisa nekugadzira maindasitiri.

●M42 (8% Cobalt): Yakagadzirirwa zvinhu zvakanyanyisa zvakaita seTitanium kana Inconel. Kunyange zvazvo ine kuoma kukuru kwetsvuku, haina kusimba kupfuura M35. Inoda michina yakasimba uye yakanyatsogadzirwa kuti isatsemuke kana yamanikidzwa nedivi.

Cobalt Inobatsira Sei Chaizvo? (Kubatsira kweMicroscopic)

Ungashamisika kuti: kuwedzera chikamu chidiki cheCobalt (5% kana 8%) kunoita sei mutsauko mukuru mukushanda? Chakavanzika chiri mumaumbirwo eatomu esimbi yechishandiso.

1. Kukwidza Tembiricha Inonyanya Kupisa

MuHSS yakajairwa, kuomarara kunobva kumakabhoyidhi akaomarara. Zvisinei, kana kupisa kuchipfuura 500°C, makabhoyidhi aya anotanga kunyungudika kana "kuoma," zvichiita kuti simbi irasikirwe nehasha dzayo uye ive yakapfava. Cobalt inoshanda se "stabilizer." Inokwidza tembiricha iyo simbi inotanga kupfava, ichiva nechokwadi chekuti mucheto wepamberi unoramba wakasimba kunyangwe kana paine kushushikana kwakanyanya kwekupisa.

2. Kusimbisa Matrix

Cobalt inoramba iri mu "mhinduro yakasimba" yesimbi. Haigadzire ma carbides ayo; panzvimbo pezvo, inosimbisa chisungo pakati pezvimwe zvinhu zvakaita seTungsten, Molybdenum, neVanadium. Funga nezveCobalt se "glue" inobata chimiro chekristaro che drill bit pamwe chete kana kupisa kuchiedza kuibvisa.

3. Kufambiswa Kwemafuta Kwakawedzerwa Pamucheto Weti

Zvinoshamisa kuti, kunyange hazvo simbi isingapindi kupisa zvakanaka, Cobalt inobatsira kuti bhora rishande nesimba zviri nani. Izvi zvinoita kuti chishandiso chirambe chine huwandu hwakanyanya hwekuomarara kwekupisa, zvichireva kuti musiyano uripo pakati pekuomarara kwekupisa kwemukamuri nekuomarara kwekupisa kwakanyanya mudiki pane wesimbi yakajairwa.

Zvikonzero zvitatu nei Cobalt iri Sarudzo yeNyanzvi

●Kuramba Kuoma Kwebasa: "Simbi isina chinhu inooma" pakarepo. Kana chidhinha chikamira kana kukwesha, pamusoro pacho panonyanya kuoma kupinda. Zvidimbu zveCobalt zvinoramba zvakapinza semupendero unoruma chinhu nguva dzose, zvichidzivirira pamusoro kuti pasaoma.
●Hupenyu hweZvishandiso Zvepamusoro: Munzvimbo yekugadzira yakawanda, "mutengo" wechishandiso unosanganisira nguva inoshandiswa kuchichinja. Zvidimbu zveCobalt zvinogara kwenguva yakareba kupfuura HSS yakajairwa, zvichireva kuti shanduko shoma dzechishandiso uye nguva shoma yekusashanda kwemuchina.
●Kushanda Nesimba Kwechokwadi Kwemari: Kunyange hazvo Cobalt bit ichigona kudhura ne30% kupfuura standard bit, inogona kubhoora maburi akawanda esimbi isingatsvedzi ka5 kusvika ka10. Izvi zvinoita kuti mutengo wepaburi rega rega uve wakaderera, zvichichengetedza mari yebhizinesi rako kwenguva refu.

Mazano eNyanzvi eKuita Basa Rakanaka

Kuti uwedzere hupenyu hwekudzidzira kwako kweJiacheng Cobalt, tevera nhungamiro idzi dzehunyanzvi:
1.Dzvisa Speed (RPM): Zvidimbu zveCobalt zvinoshanda zvakanaka nekumhanya kwakaderera. Kumhanya kwakanyanya kunogadzira kupisa kusingakoshi uko kunyange Cobalt isingagone kutsungirira nekusingaperi.
2. Kudzvanywa Kwenguva Dzose: Usamborega chikamu "chichigara" mugomba. Shandisa kudzvanywa kwakasimba uye kwakasimba kuti uve nechokwadi chekuti mipendero yekucheka iri kubvisa simbi nguva dzose.
3. Shandisa Mafuta Emhando Yepamusoro: Kunyangwe Cobalt ichiramba kupisa, mafuta ekucheka ane sarufa kana chinhu chinotonhodza chemhando yepamusoro chinobvisa machipisi uye kuwedzera hupenyu hwechishandiso.

Mhedziso

Kune chero workshop kana fekitori inoshandisa simbi isingatsvi, maCobalt drill bits haasi emhando yepamusoro chete—anokosha. Nekudyara mari mu alloy chaiyo, unoita shuwa kuti purojekiti yega yega yakavimbika, yakarurama, uye inoshanda. KuJiacheng Tools, isu tine hunyanzvi mukupa mhinduro dzemhando yepamusoro dzeM35 neM42 dzinoita kuti midziyo yako yekugadzira irambe ichienderera mberi.
