Nyaya: Nei Zvidimbu zveDrill Zvichikundikana | Chinyorwa 5
Mazwi akakosha: HSS drill bit quality, drill bit weight, drill bit hardness, HSS density, drill bit inspection, maitirwo ekuongorora drill bits
Vatengi vazhinji vanoongorora kunaka kwedhiringi vanobvunza mubvunzo unoita seuri nyore: "Kuoma kwacho chii?"
Hausi mubvunzo usina kururama. Kuomarara chimwe chezviratidzo zvakakosha zvemhando yeHSS drill bit. Asi "kuomarara kunogara kuri nani" kusanzwisisana kwakajairika - uye kusanzwisisana kunogona kuita kuti vatengi vasarudze chigadzirwa chisiri icho.
Zvinotaurwa Nekuoma Chaizvo
Kuomarara, kunowanzo kuyerwa pachikero cheRockwell C (HRC), kunoratidza kuti mupendero wekucheka unoramba sei kuchinja mushure mekupisa. Kune ma HSS drill bits, nhamba iyi yakabatana zvakananga nekuti mupendero wacho unoramba wakapinza here uye unoramba kupera panguva yekucheka.
Kurapa nekupisa ndiko kunosarudza kuomarara. Simbi imwecheteyo isina kugadzirwa - M2 kana M35, semuenzaniso - inogona kuguma nekuomarara kwakasiyana zvichienderana nekuti inobatwa sei nekupisa. Ndosaka giredhi resimbi roga risingakwanise kukuudza mhando chaiyo ye drill bit yapera. Zvinhu ndizvo zvinotangira. Kurapa nekupisa ndiro danho rinoshandura kugona ikoko kuita kushanda chaiko.
Chikonzero nei kuoma kwakanyanya kusiri nani nguva dzose
Heino chikamu chinopesana nepfungwa iyi: kusundira kuoma kwakanyanya kunogona kuita kuti drill bit ikundikane zviri nyore.
Kuenzanisa kuri nyore kunobatsira kutsanangura chikonzero nei. Chirabha chinorabha chakapfava — chinokanganisika kana chamanikidzwa uye hachigoni kuchengetedza chimiro chacho. Ndiro yeceramic yakaoma — asi haina kusimba, saka simba rimwe chete rekukanda rinogona kuipwanya ipapo ipapo. HSS drill bit inofanira kugara pakati pezvinhu zviviri izvi: yakaoma zvakakwana kuti irambe kupera, asi yakasimba zvakakwana kuti itore kuvhunduka uye kudedera kwemamiriro ekucheka chaiwo pasina kutsemuka kana yasangana nenzvimbo yakaoma muchinhu chacho.
Ndosaka chinangwa chekurapa kupisa chisiri "chakaoma sezvinobvira." Chinangwa chaicho ndechekuwana chiyero chakakodzera chekuomarara uye kusimba kwesimbi iyoyo uye kushandiswa kwayo. Chidimbu chekuboorera chine huwandu hwekuomarara hwakanyanya asi kusimba kusina kukwana chinogona kukundikana nekukurumidza mukushanda kupfuura chine kuomarara kwakaderera uye kusimba kwakakodzera - uye chinowanzo kundikana nekutsemuka kana kupwanyika, kwete nekusakara zvishoma nezvishoma.
Nei Hukukutu Huri Range, Kwete Nhamba Imwe Chete
Vatengi vanowanzoda nhamba imwe chete chaiyo yekuomarara — semuenzaniso "HRC 65." Muchokwadi, kuomarara kunogara kuri nhanho, kwete kukosha kumwe chete kwakagadzika.
Izvi zvinodaro nekuti kurapwa nekupisa kunochinja maitiro echisikigo. Kunyangwe mukati memutoro wechoto wakafanana uye muhuwandu hwakafanana hwekugadzira, kuomarara kunosiyana zvishoma kubva pachidimbu kuenda pachidimbu. Izvi zvakajairika muindasitiri yese - hazvisi zvefekitori imwe chete. Kana mutengesi akakutaurira nhamba imwe chete chaiyo uye achiti chidimbu chimwe nechimwe chinoenderana nacho chaizvo, chirevo ichocho chinofanira kubvunzwa.
Ruzivo rwechokwadi uye rwakavimbika rwekuomarara runofanira kuratidzwa sehuwandu, ruchitsigirwa nekuyera chaiko — kwete nhamba inodzokororwa kubva mundangariro. Munguva pfupi yapfuura takavandudza maitiro edu ekurapa kupisa, uye huwandu hwedu hwekuomarara hwakayerwa parizvino hunenge HRC 64–67 yeM2 uye HRC 65–69 yeM35 cobalt. Aya ndiwo marudzi anoratidza shanduko yakajairika yebatch-to-batch, kwete vimbiso yekuti chidimbu chimwe nechimwe chinowira panhamba imwe chaiyo.
Chii Chinoitika Kana Kuoma Kwacho Kwakaderera Kana Kusina Kuenzana
Kana kurapwa kwekupisa kusina kudzorwa zvakanaka, migumisiro yakajairika inosanganisira:
• Kuomarara kusina kukwana: mucheto wekucheka unopfava nguva isati yakwana panguva yekucheka, kupera kwechinhu kunokurumidza, uye nguva yekushanda kwezvishandiso inopfupika.
• Kuomarara kusina kuenzana: mamwe mapoinzi ari pachikamu chimwe chete chekuboorera akapfava kana kuti akaoma kupfuura mamwe, zvichikonzera kusakara kusina kuenzana — kana kugadzira nzvimbo dzekuisa pfungwa pachinhu apo kuomarara kunochinja kamwe kamwe, izvo zvinowanzova nzvimbo yekutanga yekupwanya.
• Kusiyana kwakanyanya kwehuwandu hwezvinhu: kunyangwe kuomarara kwakajairika kuchigamuchirwa, kusiyana kukuru mukati mehuwandu hwezvinhu kunoreva kuti vatengi vanowana ruzivo rwekuti "huwandu uhwu hwakashanda zvakanaka, hunotevera hahuna kushanda zvakanaka." Kusawirirana kwakadaro kunowanzova kwakaoma kugadzirisa mukuronga kugadzirwa kupfuura huwandu humwe chete husingakwaniswe.
Hapana chimwe chezvizvi chinoonekwa kubva kunze. Ruvara, kupenya kweganda, uye kunzwa hazvikuudze chokwadi nezvehukukutu chaihwo - musimboti mumwe chete watakakurukura munyaya yedu yapfuura wekuti nei huremu husingakwanise kuziva hunhu hweHSS. Kutonga nekuona uye kubata hakusi kutsiva kuyerwa.
Maitiro Avanogona Kuratidza Vatengi Kuoma Kwezvinhu
Kuomarara ndeimwe yezviratidzo zvishoma zvemhando zvinogona kuyerwa zvakananga pane kutongwa neruzivo rwega. Tinokurudzira vatengi:
• Bvunza mutengesi nezvemhando yekuoma kwesimbi inoshandiswa kugadzira mabhora ekuboorera.
• Pakuodha zvinhu zvakakosha, kumbira mutengesi kuti aedze kuomarara panzvimbo yacho achishandisa Rockwell hardness tester panguva yekugadzira, kana kushandisa Rockwell tester yako kuti uone masampuli ari kuuya - iyi inzira inoshanda yekusimbisa iri pedyo nemakambani mazhinji.
• Usanyanya kutarisisa nhamba yekuoma kwayo chete, asi kana nhamba iyoyo inoratidzwa senzvimbo yakayerwa ine data chairo riri shure kwayo, pane kuti ionekwe senhamba yakatorwa kubva mundangariro.
Nezvenyaya iyi
Chikonzero nei Drill Bits Isingashande inyaya yehunyanzvi yakanyorwa nechikwata chedu chekugadzira. Chinyorwa chimwe nechimwe chinotarisa pane chimwe chinhu chaicho mukushanda kwedrill bit - kubva pazvinhu zvisina kugadzirwa kusvika pakurongedza. Chinangwa chiri nyore: kubatsira vatengi kunzwisisa zvavari kutenga chaizvo, uye mibvunzo yekubvunza.
