Nhevedzano:Sei Zvidimbu Zvekudhonza Zvichikundikana | Chinyorwa 3
Mazwi akakosha:Hunhu hwe HSS drill bit, huremu hwe drill bit, kuomarara kwe drill bit, HSS density, drill bit inspection, maitiro ekuongorora drill bit
Vamwe vatengi vanoyera zvidhinha zvekuboorera pavanenge vachiongorora sampuro dzemutengesi mutsva. Kana chidimbu chacho chikanyanya kurema, simbi yacho inova nani — kana kuti ndizvo zvinoita kuti pfungwa yacho ishande.
Ipfungwa inonzwisisika. Kurema kunoita sechiratidzo chechinhu chaicho. Asi kana zvasvika kuma HSS drill bits, huremu chimwe chezviratidzo zvisingavimbike zvemhando yepamusoro. Mune zvimwe zviitiko, drill bit inorema chiratidzo chechigadzirwa chemhando yepasi.
Heino chikonzero.
HSS Density Haichinje Zvikuru Pakati Pemagiredhi
High Speed Steel imhuri chaiyo yesimbi dzezvishandiso zvinotsanangurwa nezvinhu zvayo zvekubatanidza — tungsten, molybdenum, chromium, vanadium, uye mumhando dze cobalt, cobalt. Zvinhu izvi zvinowedzerwa muzvikamu zvidiki kuti zvidzore kuomarara, kuramba kupfeka, uye kuomarara kutsvuku.
Kuwanda kweHSS mumagiredhi akafanana — M2, M35, M42 — kuri pakati pe8.1 kusvika 8.3 g/cm³. M2 neM35 zvakasiyana muhuwandu hwecobalt (0% vs. inenge 5%), asi huwandu hwecobalt (inenge 8.9 g/cm³) hwakafanana zvakakwana nesimbi yesimbi iyo inosanganisa 5% yayo mu alloy inoshandura huwandu hwese nepasi pe0.1 g/cm³. Musiyano iwoyo hauonekwe nemaoko uye haunyanyi kukosha kunyangwe pachikero chekunyatsojeka.
Mukutaura kunoshanda: haugone kushandisa huremu kusiyanisa M2 neM35, kana HSS yakajairwa kubva kuHSS yemhando yecobalt.
Saka Sei Mamwe Madhiri Ekuchera Achinzwa Kurema?
Kana zvibooreso zviviri zvehukuru hwakafanana zvichiratidzika zvakasiyana zvakanyanya muhuremu, tsananguro yacho inowanzova yejometri - kwete yezvinhu.
Huremu hwechidhinha cheboore hunoenderana nehuwandu hwezvinhu zvirimo. Pahurefu nedhayamita yakatarwa, chinhu chikuru chinoenderana nekuti simbi yakawanda sei yakabviswa panguva yekukuya. Firimu - kudzika nehupamhi hwemigero yakachekwa mumuviri - zvinodzora izvi zvakananga. Firimu dzakadzika uye dzakafara dzinobvisa zvinhu zvakawanda. Firimu dzisina kudzika dzinosiya zvakawanda.
Mugadziri anogona kugadzira chidimbu chinorema chekuboorera nekukuya nyere dzisina kudzika. Chidimbu chinochengeta zvinhu zvakawanda zvepakati, saka chinorema zvakanyanya. Asi nyere dzisina kudzika dzine mhedzisiro: kubviswa kwemachipisi kunoderera, kuderedza kukweshana kunowedzera, uye kupisa kunowedzera nekukurumidza panzvimbo yekucheka. Muzvinhu zvakaoma kana pakudya kwepamusoro, izvi zvinotungamira mukusakara nekukurumidza uye njodzi yakakura yekukundikana nguva isati yakwana.
Izvi zvinoreva kuti bhora rinorema harisi iro riri nani pakuboorera. Rinogona kungova iro kona yakachekwa muchimiro chejometri - uye mutengi ari kukanganisa chiratidzo chacho sechiratidzo chemhando yepamusoro.
Zvinonyatsoratidza Kurema
Huremu hunoratidza huwandu hwesimbi yasara. Huwandu hunodzorwa nekukuya. Hunhu hwekukuya chisarudzo chekugadzira.
Mugadziri ane ruzivo anokwesha nyere zvichienderana ne geometry yakatarwa nekushandiswa - DIN 338 kana zviyero zvakafanana zvinotsanangura angle yehelix, kudzika kwenyere, uye point geometry nechikonzero. Zviyero izvi zvakagadziriswa mukati memakumi emakore ekushandiswa kwemaindasitiri kuti zvienzane nekubvisa chips, simba repamusoro, uye kushanda zvakanaka kwekuboora.
Chidimbu chekuboorera chinosiyana kubva pachimiro chemazuva ose kuti chiite sechinorema hachina kuvandudzika pakuenzana ikoko. Chakanganisa kuenzana kwacho.
Zviyero Zvinonyanya Kukosha
Kana huremu husiri chiratidzo chakavimbika, vatengi vanofanira kutarisa chii pavanenge vachiongorora mhando ye drill bit?
Zvinhu zvine zvazvinoreva ndeizvi:
•Kuoma.Mushure mekupisa, mupendero wekucheka kweM2 HSS drill bit yakagadzirwa zvakanaka unofanirwa kusvika paHRC 63–65. M35 cobalt inofanira kusvika paHRC 64–66. Hunhu hwekuomarara kunze kweaya maerekitironi hunoratidza matambudziko ekupisa - kungave kupisa kushoma, mwero wekudzimwa kwemvura usina kukwana, kana kudzora kupisa kwakashata. Kuomarara kunogona kuyerwa zvakananga neRockwell hardness tester.
•Kuumbwa kwezvinhu.Kuongororwa kweSpectrometer (OES — Optical Emission Spectrometry) ndiyo chete nzira yakavimbika yekuona kana drill bit ine zvinhu zve alloy zvakataurwa. Cobalt content, tungsten percentage, vanadium — hapana chimwe chezvizvi chinoonekwa kana chinorema. Zvinoda kuongororwa murabhoritari.
•Kururama kwejiyometri.Kona yekona, kona yehelix, flute symmetry, uye mamiriro emucheto wechisel zvese zvinokanganisa mashandiro ekucheka. Izvi zvinoyerwa nezvishandiso zvekuyera zve optical kana maprojekita eprofile.
•Kuenderana kweboka.Sampuro imwe chete inopfuura haina kukwana. Vatengi vemaindasitiri vanoda mashandiro anoenderana nekugadzirwa kwese. Kuoma, jiometri, uye kupenya kwechinhu pakati pemazana kana zviuru zvezvidimbu inyaya yemaitiro ekugadzira, kwete mubvunzo wekuongorora weyuniti imwe chete.
•Kupedzisa pamusoro.Hunhu hwekukuya hunoonekwa. Mavanga ekukuya asina kunaka, nzvimbo dzisina kuenzana dzeflute, kana mavanga anonzwika ekuchema pamucheto wekare zviratidzo zvematambudziko ekushanda. Chidimbu chekuboorera chakakuyiwa zvakanaka chinoratidza nzvimbo dzakachena, dzakatsetseka dzeflute dzine miganhu yakafanana.
Zvinorevei Izvi paSarudzo dzeKutsvaga Basa
Kana mutengesi achitumira sampuro, rambai nepfungwa yekuti dziongororwe nehuremu. Cheki ine musoro ndeyekukumbira chitupa chezvinhu, kuongorora jiometri pasi pekukwidziridzwa kana zvichibvira, uye - kune maodha akakosha - kukumbira data rekuyedza kuomarara kana kusimbiswa kwezvinhu zvakazvimiririra.
Kurema hakusi nzira yekupfupisa. Iruzha.
Hunhu hwe HSS drill bit hunoenderana nekugadzirwa kwayo kwesimbi, kurapwa kwayo nekupisa, uye mamiriro ayo evhu. Hapana chimwe chezvizvi chinoratidzwa pachikero.
Nezve Nyaya Ino
Chikonzero nei Drill Bits Isingashande inyaya yehunyanzvi inobva kuchikwata chedu chekugadzira zvinhu. Chinyorwa chimwe nechimwe chinotarisa pane chimwe chinhu chinoita kuti drill bit ishande zvakanaka — kubva pazvinhu zvisina kugadzirwa kusvika pakurongedza. Chinangwa chacho chiri nyore: kubatsira vatengi kunzwisisa zvavari kutenga chaizvo, uye mibvunzo ipi yakakodzera kubvunzwa.
