Iyo abaguzi batubajije ibijyanye n'uduce twa HSS drill, kimwe mu bibazo bikunze kugaragara ni iki: "Ni irihe tandukaniro riri hagati ya M42, M35, M2 — kandi se 4341 itandukaniye he?
Ni ikibazo cyumvikana. Byose ni ibikoresho by'icyuma cyihuta cyane (HSS), kandi hejuru, bisa hafi kimwe. Ariko urwego uhisemo rugira ingaruka ku gihe imashini yawe imara, uko ikora mu gihe cy'ubushyuhe, ndetse niba ikwiriye ibikoresho urimo gukata.
Dore isesengura ryoroheje.
HSS ni iki, kandi kuki amanota ari ingenzi?
HSS isobanura High-Speed Steel — icyuma gikozwe mu cyuma cyakorewe mu gukata icyuma ku muvuduko wo hejuru kidatakaza ubukana bwacyo. Bitandukanye n'icyuma cya karuboni, HSS igumana imbaraga zayo zo guca icyuma nubwo cyashyuha cyane mu gihe cyo gucukura.
Ariko si HSS zose zimeze kimwe. Ingano — M42, M35, M2, 4341, n'izindi — yerekeza ku miterere yihariye y'aloyi. Itandukaniro rito mu bintu nka tungsten, molybdenum, vanadium, na cobalt rituma habaho itandukaniro rikomeye mu mikorere.
Icyitonderwa: M42 ikoresha uburyo butandukanye na M35 — ikoresha molybdenum nyinshi cyane aho gukoresha tungsten iremereye, ibi bikaba bituma irushaho kugira ubushyuhe bukabije ku giciro gito cy’aloyi.
HRC yo hejuru bivuze ko idapfa kwangirika neza - ariko nanone ikaba yoroshye gato. M42 niyo ikomeye cyane, ariko ikeneye imiterere ihamye kandi ikomeye kugira ngo wirinde gucika. 4341 niyo yoroshye kandi ikomeye cyane, bituma irushaho kuba nziza mu mikoreshereze rusange.
M42 — Igipimo cyo hejuru cy'imikorere ku bikoresho bigoye
M42 iri ku isonga mu cyiciro cya HSS. Ifite 8% bya kobalti na molybdenum nyinshi cyane (HS2-9-1-8, izwi kandi nka HSSCo8, SKH59, P2M9K8, cyangwa S500), yagenewe ibikoresho byahita byangiza imashini isanzwe ya HSS.
Turimo kuvuga ku byuma bikozwe muri nikeli, titaniyumu, ibyuma bikomeye, superalloys zirinda ubushyuhe - ibikoresho indege, ubwugarizi, n'inganda zigezweho zishingiraho. M42 ibikora kuko ishobora kwihanganira ubushyuhe burenga dogere selisiyusi 680 mu gihe ikomeza gukora neza kandi neza.
Impinduka ni uko M42 irushaho kugorana kurusha imiterere iri munsi yayo. Ikora neza mu buryo bukomeye kandi bugenzurwa aho guhindagurika bigabanuka. Nanone ihenda cyane - ariko iyo uyikoresheje neza, igihe kirekire cyo kuyikoresha kirahagije.
M35 — Iyo Urimo Gucukura Ibikoresho Bikomeye
M35 yongeraho 5% bya cobalt ku gishingo cya M2 (niyo mpamvu izina rindi HSSCo5 cyangwa HS6-5-2-5). Iyo cobalt yongera ubushyuhe bw'imashini - kugeza kuri 630–650°C - kandi igatuma ubukana bugera kuri 63–66 HRC.
Ku bacuruzi batanga ibikoresho mu nganda nka za automotive, HVAC, cyangwa ibikoresho byoroheje — aho ibyuma bitagira umugese bikunze gukoreshwa — M35 ni ivugururwa ry’ikoranabuhanga ugereranyije na M2. Irakomeye, ntishaje cyane, kandi itanga igihe kirekire cy’ibikoresho mu bihe bigoye cyane nta kibazo cya M42 cyo kwangirika.
Tekereza kuri M35 nk'ahantu heza: ni nziza kurusha HSS isanzwe, ariko ikaba ikiri ingirakamaro kandi yizewe mu buryo butandukanye bw'aho bakorera.
M2 — Igipimo Gikora ku Mirimo Itari Minshi
M2 ni yo ngano ya HSS ikoreshwa cyane ku isi. Izina ryayo ryuzuye ni HS6-5-2 (izwi kandi nka SKH51 cyangwa P6M5), igaragaza imiterere yayo: 6% tungsten, 5% molybdenum, 2% vanadium - nta cobalt.
Ni ibikoresho bisanzwe byo gucukura mu buryo rusange mu byuma bitandukanye — icyuma cyoroshye, aluminiyumu, umuringa, icyuma gishongeshejwe, n'ibindi. Imashini za M2 ziraseye neza, zirahoraho, kandi zirahendutse. Ku bidukikije byinshi bisanzwe byo gukoreramo no gukora, M2 ni yo ukeneye.
Iyo umuguzi atavuze amanota, M2 ni yo ahabwa hafi ya yose — kandi ku bikorwa byinshi, ibyo ni byiza cyane.
4341 — Uburyo bukomeye kandi bukoreshwa mu buryo butandukanye bwo kwinjira ku rwego rwo hejuru
4341 (yanditswe kandi nka W4Mo3Cr4VSi) ni ubwoko bwa HSS bwa tungsten-molybdenum buri munsi ya M2 mu mikorere, ariko butanga imbaraga n'ubudahangarwa bwiza. Bukunzwe cyane cyane mu masoko aho gukoresha neza ikiguzi ari byo by'ingenzi.
Ugereranyije na M2, 4341 ifite ubukana buke kandi ubukana bukabije bugabanuka - bivuze ko itabasha kwihanganira ubushyuhe bwinshi. Ariko ku gucukura ibyuma byoroshye cyangwa mu bikorwa aho imashini zikunze gusimburwa aho gukomeza gukoreshwa, ikora akazi neza kandi mu buryo bwizewe.
4341 ni amahitamo asanzwe ku bikoresho byo gucukura bipakiye bigurishwa mu maduka no mu bikoresho, aho igiciro cy'ibikoresho ari cyo cy'ingenzi kuruta imikorere myiza cyane. Si cyo gikoresho cyiza cyane ku bikoresho bikomeye — ariko ku kazi koroheje ka buri munsi, ni cyo gihabwa umwanya wacyo.
Uburyo bwo guhitamo: Incamake y'incamake
Ibyo dutanga muri Jiacheng Tools
Muri Jiacheng Tools, dukora uduce two gucukura two mu byiciro bine — M42, M35, M2, na 4341. Byose biboneka nk'ibicuruzwa bya OEM/private label, kandi dukorana n'abakwirakwiza ibicuruzwa ku isi yose kugira ngo duhuze amanota akwiye n'isoko ryabo.
Niba utazi neza amanota akwiriye abaguzi bawe, itsinda ryacu ryishimiye kukugira inama hashingiwe ku ikoreshwa rya nyuma. Akenshi, ikiganiro cyoroshye ku bikoresho abakiriya bawe barimo gukora gishobora kugira icyo gihindura mu mikorere y'ibicuruzwa - no mu mabwiriza asubirwamo.
