Kana vatengi vakatibvunza nezve HSS drill bits, mumwe wemibvunzo inowanzo bvunzwa ndewekuti: "Musiyano uripo pakati peM42, M35, M2 ndeupi — uye ko 4341?
Mubvunzo wakanaka. Zvese izvi zvinhu zvesimbi zvinomhanya zvakanyanya (HSS), uye pamusoro, zvinotaridzika zvakafanana. Asi mhando yaunosarudza ine chekuita nekuti bhora rako rinogara kwenguva yakareba sei, kuti rinoita sei kana richipisa, uye kana rakanyatsokodzera chinhu chauri kucheka.
Heino tsananguro iri nyore.
Chii chinonzi HSS, uye Nei Giredhi Richikosha?
HSS inomiririra High-Speed Steel — chiumbwa chesimbi chinoshandiswa pakucheka simbi nekumhanya kwakanyanya pasina kurasikirwa nekuoma kwayo. Kusiyana nesimbi yekabhoni, HSS inoramba iine mucheto wayo wepamusoro kunyangwe painopisa panguva yekuboora.
Asi hazvisi zvese zveHSS zvakafanana. Chiyero — M42, M35, M2, 4341, nezvimwe — zvinoreva chimiro chealloy chaiyo. Kusiyana kudiki muzvinhu zvakaita setungsten, molybdenum, vanadium, uye cobalt kunotungamira kune kusiyana kukuru mukushanda.
Cherechedza: M42 inoshandisa nzira yakasiyana neM35 — inoshandisa molybdenum yakawanda panzvimbo petungsten inorema, izvo zvinoita kuti iite seyakaomesesa uye ine mutengo wakaderera we alloy.
HRC yakakwirira zvinoreva kuti haipfeki zvakanaka — asiwo kuti isanyanya kusimba. M42 ndiyo yakaoma, asi inoda kugadziriswa kwakasimba uye kwakasimba kuti isatsvedze. 4341 ndiyo yakapfava uye yakaoma, izvo zvinoita kuti ikwanise kushandiswa zvakanyanya.
M42 — Giredhi Repamusoro-soro reMagadzirirwo Akaoma
M42 ndiyo iri pamusoro peHSS hierarchy. Iine 8% cobalt uye molybdenum yakawanda (HS2-9-1-8, inozivikanwawo seHSSCo8, SKH59, P2M9K8, kana S500), yakagadzirirwa zvinhu zvinokurumidza kusakadza HSS drill yakajairika.
Tiri kutaura nezve nickel alloys, titanium, simbi dzakaomarara, superalloys dzisingapisi — zvinhu zvinoshandiswa nendege, dziviriro, uye kugadzirwa kwepamusoro. M42 inobata izvi nekuti inogona kutsungirira tembiricha dzinopfuura 680°C uku ichiramba iine mucheto wakanaka uye wakapinza.
Chinhu chakanaka ndechekuti M42 haina kusimba kupfuura magiredhi ari pasi payo. Inoshanda zvakanaka kana yakagara yakasimba uye ichidzorwa uko kudedera kushoma. Inodhurawo zvakanyanya - asi kana ikashandiswa nemazvo, kugara kwenguva refu kwemudziyo kunoratidza kuti haina mhosva.
M35 — Paunenge Uchichera Zvinhu Zvakasimba
M35 inowedzera 5% cobalt kuM2 base (ndosaka zita rayo rekuti HSSCo5 kana HS6-5-2-5). Kuwanda kwe cobalt uku kunoita kuti drill isapise kupisa zvakanyanya — kusvika pa630–650°C — uye kunoita kuti kuomarara kusvike pa63–66 HRC.
Kune vanopa zvinhu kumaindasitiri akadai semotokari, HVAC, kana kugadzira zvinhu zvidiki — uko kwakajairika kugadzira simbi isingatsvedzeri — M35 imhando yepamusoro-soro kupfuura M2. Yakaoma, haiparare, uye inoita kuti zvishandiso zvigare kwenguva refu mumamiriro ezvinhu akaomarara pasina kunetseka kwekuputsika kweM42.
Funga nezveM35 senzvimbo yakanaka: iri nani pane HSS yakajairwa, asi ichiri kushanda uye yakavimbika munzvimbo dzakasiyana-siyana dzemaworkshop.
M2 — Muyero Unoshanda kuMabasa Mazhinji
M2 ndiyo HSS grade inoshandiswa zvakanyanya pasi rose. Zita rayo rakazara ndiHS6-5-2 (inozivikanwawo seSKH51 kana P6M5), izvo zvinoratidza chimiro chayo: 6% tungsten, 5% molybdenum, 2% vanadium — isina cobalt.
Ndiyo inoshandiswa zvakanyanya pakuboorera simbi dzakasiyana-siyana — simbi isina kusimba, aruminiyamu, mhangura, simbi yakakandwa, nezvimwewo. Maboorera eM2 anogayiwa zvakakwana, akafanana, uye anodhura zvishoma. Kune akawanda maworkshop nenzvimbo dzekugadzira, M2 ndiyo chaiyo yaunoda.
Kana mutengi asina kutaura kuti api giredhi, M2 ndiyo inenge nguva dzose yaari kuwana — uye kune akawanda maapplication, izvozvo zvakanaka chose.
4341 — Sarudzo Yakasimba uye Inoshandiswa Pakuchinja-chinja
4341 (yakanyorwawo seW4Mo3Cr4VSi) imhando yeHSS ye tungsten-molybdenum iri pasi peM2 mukushanda kwayo, asi inopa kusimba kwakanaka uye kuramba kukanganiswa. Inonyanya kufarirwa mumisika uko kushandiswa kwemari kuri iko kunonyanya kukosheswa.
Kana tichienzanisa neM2, 4341 ine kuomarara kwakaderera uye kupisa kwakaderera — zvichireva kuti haigone kumira zvakanaka kana tembiricha yakakwira. Asi pakuboora simbi dzakapfava kana mukushandiswa uko mabhora anowanzo tsiviwa pane kugadziriswa, inoita basa racho nenzira yakavimbika uye isingadhuri.
4341 isarudzo yakajairika yemaseti edhirivhari akaputirwa anotengeswa kuburikidza nezvitoro uye nzira dzehardware, uko mutengo unonyanya kukosha kupfuura kushanda kwepamusoro. Haisi chishandiso chakanakisa chezvishandiso zvakasimba - asi pabasa remazuva ese remazuva ese, rinowana nzvimbo yaro.
Maitiro Ekusarudza: Tsanangudzo Yekukurumidza
Zvatinopa paJiacheng Tools
KuJiacheng Tools, tinogadzira madhiri emhando dzese ina — M42, M35, M2, uye 4341. Zvese zviripo sezvigadzirwa zveOEM/zvakavanzika, uye tinoshanda nevanotengesa pasi rese kuti tienzanise mhando chaiyo yemusika wavo chaiwo.
Kana musina chokwadi chekuti ndechipi chibodzwa chakakodzera vatengi venyu, timu yedu inofara kukupai mazano zvichibva pane zvamashandisa. Kazhinji, hurukuro iri nyore pamusoro pezvinhu zviri kushandiswa nevatengi venyu inogona kuita mutsauko mukuru mukushanda kwechigadzirwa - uye mukudzokororwa kweodha.
