Intsimbi enesantya esiphezulu, ekwabizwa ngokuba yiHSS, luhlobo lwentsimbi yesixhobo esetyenziswa kakhulu kushishino lokuvelisa ngenxa yeempawu zayo ezintle. Yimpahla ephezulu yokusebenza enokumelana nokushisa okuphezulu kunye nokusebenza kwe-high-speed machining, okwenza kube yinto efanelekileyo yokusika izixhobo, i-drill bits kunye nezinye izicelo zetsimbi.
Enye yeempawu eziphambili zentsimbi yesantya esiphezulu kukukwazi ukugcina ubunzima kunye nokukwazi ukusika nakwiqondo lokushisa eliphezulu. Oku kubangelwa ubukho bezinto ezidibeneyo ezifana ne-tungsten, i-molybdenum, i-chromium kunye ne-vanadium, eyenza i-carbides enzima kwi-matrix yensimbi. Ezi carbides zixhathisa kakhulu ukunxiba kunye nobushushu, zivumela isinyithi esinesantya esiphezulu ukuba sigcine umgca wokusika nokuba siphantsi kobushushu obugqithisileyo kunye nokukhuhlana ngexesha lomatshini.

Olunye uphawu olubalulekileyo lwentsimbi yesantya esiphezulu bukuqina kwayo okugqwesileyo kunye nokuqina. Ngokungafaniyo nezinye izixhobo zentsimbi, i-HSS iyakwazi ukumelana neempembelelo eziphezulu kunye nemithwalo yokothuka ngaphandle kokuqhekeka okanye ukwaphuka. Oku kuyenza ifanelekele izicelo zokusika ezinzima apho isixhobo sixhomekeke kwimikhosi ebalulekileyo ngexesha lokusebenza.
Ukongeza kwiipropathi zayo zemishini, i-high-speed steel nayo ine-machinability efanelekileyo, evumela ukuba kube nokusebenza ngokufanelekileyo kunye nokuchaneka kweenkqubo kunye nokwenza iinkqubo. Oku kwenza kube lula ukuba abavelisi bavelise uyilo lwezixhobo ezintsonkothileyo besebenzisa i-HSS, izixhobo ezivelisa izixhobo ezinokufezekisa ukunyamezelana okuqinileyo kunye nokugqitywa komphezulu ophezulu.
I-HSS yaziwa nangokuguquguquka kwayo, njengoko inokusetyenziselwa ukusetyenzwa kwezixhobo ezahlukeneyo, kubandakanya intsimbi yekhabhoni, intsimbi yealloyi, intsimbi engatyiwa, kunye neentsimbi ezingenayo i-ferrous. Oku kuyenza ibe lukhetho oludumileyo lwezixhobo zokusika eziziinjongo ngokubanzi ezifuna ukuphatha imisebenzi yomatshini eyahlukeneyo.

Ukongeza, i-HSS inokunyangwa ngokulula ubushushu ukufezekisa indibaniselwano efunekayo yokuqina, ukuqina kunye nokumelana nokunxiba, ukuvumela iipropathi zezinto eziphathekayo ukuba zilungelelaniswe kwiimfuno ezithile zesicelo. Le bhetyebhetye unyango ubushushu ivumela abavelisi ukuba balungise ukusebenza HSS izixhobo zokusika kwiimeko machining ezahlukeneyo kunye nezixhobo workpiece.
Kwiminyaka yakutshanje, ukuqhubela phambili kwi-teknoloji ye-high-speed steel kuye kwakhokelela ekuphuhlisweni kwamabakala amatsha ensimbi kunye neengoma ezinikezela amanqanaba aphezulu okusebenza. Ezi nkqubela zivumela izixhobo zokusika isinyithi esinesantya esiphezulu ukuba zisebenze ngesantya esiphezulu sokusika kunye namaqondo okushisa, ukwandisa imveliso kunye nokugcinwa kweendleko kubakhiqizi.
Ngaphandle kokuvela kwezinye izixhobo zesixhobo ezifana ne-carbide kunye nokufakwa kwe-ceramic, isinyithi esinesantya esiphezulu sihlala sithandwa kwizicelo ezininzi zesinyithi ngenxa yokudibanisa kwayo okulungileyo, ukusebenza kakuhle, kunye nokulula ukuyisebenzisa. Ikhono layo lokumelana namaqondo okushisa aphezulu, ukugcina umgca wokusika obukhali, kunye nokumelana nokugqoka kunye nefuthe kwenza kube yinto ethembekileyo kunye neyohlukeneyo yezinto ezahlukeneyo zokusika kunye nokusebenza ngomatshini.
Isishwankathelo, i-HSS yimathiriyeli exabisekileyo kwimveliso kunye nendibaniselwano ekhethekileyo yokuqina, ukuqina, ukuxhathisa ukunxiba kunye nokusebenza. Ukukwazi ukwenza kakuhle kwisantya esiphezulu kunye nokushisa okuphezulu kwenza kube yinto ebalulekileyo yokukhetha izixhobo zokusika kunye nezinye izicelo zesinyithi. Ngophando oluqhubekayo kunye neenzame zophuhliso, i-HSS ilindeleke ukuba iqhubeke nokuvela ukuze ihlangabezane neemfuno ezikhulayo zeenkqubo zanamhlanje zokwenza.
