Yintoni i-HSS Twist Drill Bit?
I-HSS twist drill luhlobo lwesixhobo sokomba esenziwe nge-High-speed steel esetyenziselwa ukusetyenzwa kwesinyithi. I-HSS yintsimbi ekhethekileyo yealloyi enokumelana ne-abrasion egqwesileyo, ukuzinza kwe-thermal, kunye neempawu zokusika, iyenza ilungele imisebenzi yesinyithi efana nokugrumba. I-twist drill (ekwabizwa ngokuba yi-auger okanye i-spiral flute drill) sisixhobo esinefluti ene-helical evumela iitshiphusi zokusika ukuba ziphume emngxunyeni wokubhoboza ngokukhawuleza, ukunciphisa ukukhuhlana kunye nobushushu ngexesha lokomba kunye nokuphucula ukusebenza kakuhle kokomba. Uyilo lwe-HSS twist drills lubenza balungele uluhlu olubanzi lwezixhobo zetsimbi ezahlukeneyo, kuquka intsimbi, i-aluminium, ubhedu kunye ne-alloys, njl njl.
Iimpawu zoKwenziwa kweeNsimbi zokujija iintsimbi ezikwisantya esiphezulu
1. Ukuchasana kwe-Abrasion High-Speed-Speed-Speed-Speed-Speed-Speed-Speed-Speed-high-speed-high-speed-high-speed resistant-abrasion resistance, evumela ukuba imida yokusika ihlale ibukhali ixesha elide.
2. Ukuzinza kobushushu obuphezulu: Insimbi enesantya esiphezulu ingasebenza kwiindawo eziphakamileyo zokushisa ngaphandle kokulahlekelwa okukhulu kobunzima okanye ukuguqulwa.
3. Umsebenzi ogqwesileyo wokusika: Uyilo lwe-spiral groove lwe-twist drills lunegalelo ekusikeni kwesinyithi esisebenzayo ngelixa kuncitshiswa ukuqokelelwa kwe-chip.
4. Umgangatho woMatshini othembekileyo: I-speed-speed steel twist drills ngokuqhelekileyo ihambisa imingxuma egrunjiweyo ekumgangatho ophezulu enemilinganiselo echanekileyo kunye neendawo ezigudileyo.
Iintlobo ze-HSS eSizisebenzise kwii-Twist Drills zethu
Awona mabanga aphambili eHSS esiwasebenzisayo ngala: M42, M35, M2, 4341, 4241.
Kukho ukungafani phakathi kwabo, ngokukodwa kuhambelana nokubunjwa kweekhemikhali, ubunzima, ukuzinza kwe-thermal kunye neendawo zokusetyenziswa. Ngezantsi ngowona mahluko uphambili phakathi kwala mabanga e-HSS:
1. M42 HSS:
I-M42 iqulethe i-7% -8% cobalt (Co), i-8% molybdenum (Mo) kunye nezinye i-alloys. Oku kunika ukuxhathisa okungcono kwe-abrasion kunye nokuzinza kwe-thermal. I-M42 idla ngokuba nobunzima obuphezulu, kwaye ubulukhuni bayo be-rockwell yi-67.5-70(HRC) enokufumaneka ngobuchule bonyango lobushushu.
2. M35 HSS:
I-M35 iqulethe i-4.5% -5% ye-cobalt kwaye iphinde ibe nokuxhathisa okukhulu kwe-abrasion kunye nokuzinza kwe-thermal. I-M35 inzima kancinci kune-HSS eqhelekileyo kwaye ngokuqhelekileyo igcina ubulukhuni be-betweeb 64.5 kunye ne-67.59 (HRC). I-M35 ifanelekile ukusika izinto ezincangathi ezifana nentsimbi engenasici.
3. M2 HSS:
I-M2 iqulethe amanqanaba aphezulu e-tungsten (W) kunye ne-molybdenum (Mo) kwaye ineempawu ezintle zokusika. Ubunzima be-M2 buhlala kuluhlu lwe-63.5-67 (HRC), kwaye ifanelekile ukucwangciswa kweentsimbi ezifuna iimfuno eziphezulu.
4. 4341 HSS:
I-4341 HSS yintsimbi yesantya esiphezulu enomxholo ophantsi kancinane we-alloy xa kuthelekiswa ne-m2. Ukuqina kugcinwa ngokubanzi ngaphezulu kwe-63 HRC kwaye ifanelekile kwimisebenzi yesinyithi ngokubanzi.
5. 4241 HSS:
I-4241 HSS ikwayi-HSS ye-alloy ephantsi equlethe izinto ezincinci zokuhlanganisa. Ukuqina kugcinwa ngokubanzi malunga ne-59-63 HRC kwaye idla ngokusetyenziselwa ukusebenza kwesinyithi ngokubanzi kunye nokugrumba.
Ukukhetha ibakala elifanelekileyo le-HSS kuxhomekeke kwiimfuno zakho zesicelo kunye nohlobo lwemathiriyeli ekufuneka iqwalaselwe. Ubunzima, ukuxhatshazwa kwe-abrasion kunye nokuzinza kwe-thermal zizinto eziphambili ekukhethweni.
