Iintsimbi zesantya esiphezulu (HSS)

(Intsimbi yesantya esiphezulu (i-HSS)), isetyenziswe ngokuyinhloko njengento yokusika (izixhobo zokusika) kunye nesixhobo esiphezulu se-alloy.I-HSS ikwasetyenziselwa izixhobo zokuvelisa kuba ilunge kakhulu ekusileni (ekwavumela ukuphinda kugaywe izixhobo ezibuthuntu, umzekelo).

Xa kuthelekiswa neentsimbi zokusebenza ezibandayo, ukusika isantya esiphindwe kathathu ukuya kwezine phezulu kwaye ngaloo ndlela ubushushu obuphezulu besicelo bunokufezekiswa.Oku kungenxa yonyango lobushushu apho intsimbi ifakwa kwi-1,200 °C kwaye ipholiswe.

I-HSS ifumana ubulukhuni bayo kwisakhiwo sayo esisisiseko, esibandakanya ikakhulu intsimbi kunye nekhabhoni.Ukongeza, izongezo ze-alloying ezingaphezu kwe-5% ziqulathwe, okwenza i-HSS ibe yintsimbi ephezulu.

Izinto eziluncedo zeHSS ngokubanzi

·Ubushushu besicelo bungaphezu kwama-600°C

·Izantya zokusika eziphezulu

·Amandla aphezulu (amandla ophuka kakhulu)

·Ukugaya okulungileyo ngexesha lemveliso

·Ukugcinwa kakuhle kwezixhobo ezibuthuntu

·Ixabiso eliphantsi ngokwentelekiso

Ukuphakama komxholo we-cobalt, ukuqina kwensimbi yesixhobo.Umxholo we-cobalt wonyusa ukuxhathisa kobunzima obushushu kwaye unokwenza ngcono ukusika izinto ekunzima ukuzisika.I-M35 iqulethe, i-4.8 - 5 % ye-cobalt kunye ne-M42, i-7.8 - 8% ye-cobalt.Ngokunyuka kobunzima, nangona kunjalo, ubunzima buyancipha.

Usetyenziso

Isantya esiphezulu sentsimbi, kunye needigri zayo ezahlukeneyo zobunzima kunye neengubo, zifanelekile kwizicelo ezahlukeneyo.

Yeyiphi intsimbi yesantya esiphezulu oyidingayo kwisicelo sakho ixhomekeke kwinkqubo yakho yokusika, nokuba uyagrumba, uyadiza okanye uyantywila.

Isiphelo kunye nesishwankathelo

Iidrill zenziwe ngentsimbi edibeneyo enesantya esiphezulu (HSS).Ngesi sixhobo sensimbi, ubushushu bokusebenza obufikelela kwi-600 °C bunokufikelelwa, obunokuthi kwenzeke xa kusikwa umz. intsimbi okanye isinyithi.

Njengoko ubunzima bezinto ezibonakalayo bukhula, ungasebenzisa isantya esiphezulu sensimbi kunye nomxholo ophezulu we-cobalt (5% okanye ngaphezulu).Ukuphakama komxholo we-cobalt kufuneka kuxhomekeke kwisicelo sakho.Umzekelo, ukuba ufuna ukugrumba intsimbi engenasici, ngokuqhelekileyo usebenzisa i-M35 twist drill engafakwanga.Kwezinye iimeko isixhobo sentsimbi ye-HSS ene-TiAlN yokugquma yanele.

Ngoku unokukhetha intsimbi efanelekileyo kwisicelo sakho.
