Izingcezu zamathuluzi ze-High-Speed Steel (HSS) ziyingxenye ebalulekile emhlabeni womshini wokunemba. Lawa mathuluzi okusika aklanyelwe ukumelana namazinga okushisa aphezulu futhi alondoloze ubulukhuni bawo, awenze alungele uhla olubanzi lwezinhlelo zokusebenza zemishini. Kulesi sihloko, sizohlola izici zamabhithi amathuluzi e-HSS, izinhlelo zokusebenza, kanye nezinzuzo abazinikeza ochwepheshe bemishini nabakhiqizi.
Izingcezu zamathuluzi e-HSS zenziwe ngohlobo olukhethekile lwensimbi oluqukethe amazinga aphezulu ekhabhoni, i-tungsten, i-chromium, i-vanadium, nezinye izakhi ze-alloying. Lokhu kwakheka okuyingqayizivele kunikeza ithuluzi le-HSS izingcezu zamathuluzi obunzima obungavamile, ukumelana nokuguga, kanye nekhono lokugcina umkhawulo wawo wokusika emazingeni okushisa aphezulu. Ngenxa yalokho, izingcezu zamathuluzi e-HSS ziyakwazi ukwenza izinto ezihlukahlukene, okuhlanganisa insimbi, insimbi engagqwali, insimbi ewuketshezi, nezinsimbi ezingenayo insimbi.
Enye yezinzuzo ezibalulekile zamabhithi amathuluzi e-HSS amandla azo okugcina umkhawulo wawo wokusika ngesivinini esikhulu kanye nokuphakelayo. Lokhu kubenza bafaneleke kahle ekusebenzeni kwemishini yesivinini esikhulu, lapho ithuluzi lokusika lingaphansi kokushisa okukhulu nokungqubuzana. Ukumelana nokushisa kwamabhithi amathuluzi e-HSS kuzivumela ukuthi zisebenze ngesivinini esikhulu sokusika ngaphandle kokuphazamisa ukusebenza kwazo, okuholela ekukhiqizeni okuthuthukisiwe nokusebenza kahle ezinqubweni zomshini.
Ngaphezu kokumelana nokushisa kwazo, izingcezu zamathuluzi e-HSS nazo zibonisa ukumelana nokugqokwa okuhle kakhulu, okwelula impilo yazo yamathuluzi futhi kunciphisa imvamisa yoshintsho lwamathuluzi. Lokhu kunenzuzo ikakhulukazi ezindaweni zokukhiqiza zevolumu ephezulu, lapho ukunciphisa isikhathi sokuphumula kanye nezindleko zokushintshwa kwamathuluzi kubalulekile. Ukuqina kwezingcezu zamathuluzi e-HSS kuwenza abe yinketho engabizi kakhulu kubakhiqizi abafuna ukuthuthukisa imisebenzi yabo yokwenza imishini.
Ngaphezu kwalokho, amabhithi amathuluzi e-HSS aziwa ngokuguquguquka kwawo kanye nekhono lokukhiqiza amaphrofayili ahlukahlukene wokusika. Kungakhathaliseki ukuthi iyajika, ibheke, iyabhora, noma iyalutha, izingcezu zamathuluzi e-HSS zingase zisekelwe kumajiyometri ahlukahlukene ukuze kuhlangatshezwane nezidingo ezithile zomshini. Lokhu kuvumelana nezimo kuvumela ochwepheshe bemishini ukuthi bathole imisebenzi yemishini enembile neyinkimbinkimbi kalula, okwenza izingcezu zamathuluzi e-HSS zibe yimpahla ebalulekile embonini yokukhiqiza.
Ukusetshenziswa kwezingcezu zamathuluzi e-HSS kuhlukene, kusukela ekusetshenzisweni kwemishini yenjongo evamile kuye emisebenzini ekhethekile ezimbonini ezifana nokukhiqiza izimoto, i-aerospace, kanye nemishini yezokwelapha. Emsebenzini wensimbi, izingcezu zamathuluzi e-HSS zivame ukusetshenziswa kumalebula, emishinini yokugaya, namathuluzi okubhoboza ukuze kukhiqizwe izingxenye ezinokubekezelelana okuqinile kanye nokuqedwa okungaphezulu. Ikhono labo lokuphatha izinhlobonhlobo zezinto kanye nezinqubo zokuwenza kubenza babaluleke kakhulu ekukhiqizeni izingxenye ezinembayo nezingxenye.
Uma kuziwa ekukhetheni izingcezu zamathuluzi e-HSS, ochwepheshe bemishini banezinketho eziningi abangakhetha kuzo, okuhlanganisa amabanga ahlukene, okokumboza, namajiyometri. Ukukhethwa kwebhithi elifanele lethuluzi le-HSS kuncike ezintweni ezifana nokokusebenza okwenziwa ngomshini, ukusebenza kokusika, kanye nokuqedwa kwendawo oyithandayo. Ama-machinists angakwazi futhi ukwenza ngokwezifiso izingcezu zamathuluzi e-HSS ukuze avumelane nezidingo zabo zokwenza imishini, noma ngabe ukudala amaphrofayili okusika ngokwezifiso noma ukuthuthukisa ijometri yamathuluzi ukuze kusebenze okuthuthukisiwe.
Sengiphetha, izingcezu zamathuluzi e-HSS zidlala indima ebalulekile ekwenzeni imishini enembile, enikeza ukumelana nokushisa okukhethekile, ukumelana nokugqokwa, kanye nokwenza izinto ezihlukahlukene. Ikhono labo lokumelana nesivinini sokusika nokuphakelayo, okuhambisana nokuqina nekhono lokukhiqiza amaphrofayili amaningi okusika, kuwenza abe yithuluzi elibaluleke kakhulu lochwepheshe bemishini nabakhiqizi. Njengoba isidingo sezingxenye ezinemba okuphezulu siqhubeka sikhula, izingcezu zamathuluzi e-HSS zizohlala ziyinsika yemboni yemishini, eqhuba ukuqanjwa kabusha kanye nokwenza kahle ezinqubweni zokukhiqiza.
