Izinsimbi Ezisheshayo (HSS)

(Insimbi yejubane eliphezulu (HSS)), isetshenziswa ngokuyinhloko njengento yokusika (yamathuluzi okusika) futhi iyinsimbi yensimbi enengxubevange ephezulu.I-HSS iphinde isetshenziselwe amathuluzi okukhiqiza ngoba ilungele kakhulu ukugaya (okuvumela futhi ukugaywa kabusha kwamathuluzi abuthuntu, isibonelo).

Uma kuqhathaniswa nezinsimbi zokusebenza ezibandayo, isivinini sokusika izikhathi ezintathu kuya kwezine phezulu futhi ngaleyo ndlela amazinga okushisa aphezulu okusebenza angafinyelelwa.Lokhu kungenxa yokwelashwa kokushisa lapho insimbi idonswa khona ngaphezu kuka-1,200 °C bese ipholiswa.

I-HSS ithola ubulukhuni bayo esakhiweni sayo esiyisisekelo, esihlanganisa ikakhulukazi insimbi nekhabhoni.Ngaphezu kwalokho, izithasiselo ze-alloying ezingaphezu kuka-5 % ziqukethwe, okwenza i-HSS ibe yinsimbi ene-alloy ephezulu.

Izinzuzo ze-HSS ngokujwayelekile

Izinga lokushisa lohlelo lokusebenza lingaphezu kuka-600°C

·Isivinini sokusika esiphezulu

·Amandla aphezulu (amandla aphukayo aphezulu)

·Ukugaya okuhle ngesikhathi sokukhiqiza

·Ukuphindeka okuhle kwamathuluzi abuthuntu

·Intengo ephansi uma kuqhathaniswa

Ukuphakama kokuqukethwe kwe-cobalt, insimbi yethuluzi iba lukhuni.Okuqukethwe kwe-cobalt kukhulisa ukumelana nobulukhuni obushisayo futhi ungakwazi ukusika kangcono izinto okunzima ukuzisika.I-M35 iqukethe, i-cobalt engu-4.8 - 5 % ne-M42, i-7.8 - 8 % ye-cobalt.Ngokukhula kokuqina, nokho, ukuqina kuncipha.

Izinhlelo zokusebenza

Insimbi enesivinini esikhulu, enamadigri ayo ahlukene obulukhuni nezingubo zokumboza, ifanele ukusetshenziswa okuhlukahlukene.

Iyiphi insimbi enesivinini esikhulu oyidingayo ohlelweni lwakho lokusebenza incike enqubweni yakho yokusika, noma ngabe uyabhola, uyalutha noma uyacwila.

Isiphetho nesifinyezo

Ama-drill enziwe nge-alloyed high speed steel (HSS).Ngaleli thuluzi lensimbi, amazinga okushisa afinyelela ku-600 °C angafinyelelwa, okungenzeka uma kusikwa isb. insimbi noma izinsimbi.

Njengoba ubulukhuni bezinto ezibonakalayo bukhula, ungasebenzisa insimbi yesivinini esiphezulu ngokuqukethwe okuphezulu kwe-cobalt (5% noma ngaphezulu).Ukuthi okuqukethwe kwe-cobalt kufanele kube phezulu kangakanani kuncike kuhlelo lwakho lokusebenza.Isibonelo, uma ufuna ukubhola insimbi engagqwali, ngokuvamile usebenzisa i-twist drill ye-M35 engafakwanga.Kwezinye izimo insimbi yensimbi ye-HSS ene-TiAlN coating yanele.

Manje ungakhetha insimbi efanele yohlelo lwakho lokusebenza.
