Yintoni i-HSS Twist Drill Bit?
I-HSS twist drill luhlobo lwesixhobo sokugrumba esenziwe ngentsimbi ekhawulezayo esetyenziselwa ukucubungula isinyithi. I-HSS yintsimbi ekhethekileyo ye-alloy enokumelana nokukrala okugqwesileyo, uzinzo lobushushu, kunye neempawu zokusika, okwenza ukuba ilungele imisebenzi yesinyithi efana nokugrumba. I-twist drill (ekwaziwa ngokuba yi-auger okanye i-spiral flute drill) yi-drill ene-helical flutes evumela iitships zokusika ukuba ziphume emngxunyeni wokugrumba ngokukhawuleza, zinciphisa ukungqubana kunye nobushushu ngexesha lokugrumba kwaye ziphucula ukusebenza kakuhle kokugrumba. Uyilo lwee-HSS twist drills luzenza zilungele uluhlu olubanzi lwezixhobo zesinyithi ezahlukeneyo, kubandakanya isinyithi, i-aluminium, ithusi kunye nee-alloys, njl.njl. kunye nomatshini wohlobo lomthi.
Iimpawu ze-High-Speed Steel Twist Drills
1. Ukumelana Nokukrala Okuphezulu: Izixhobo zentsimbi ezikhawulezayo zibonisa ukumelana nokukrala okugqwesileyo, okuvumela imiphetho yokusika ukuba ihlale ibukhali ixesha elide.
2. Uzinzo oluphezulu lobushushu: Intsimbi ekhawulezayo inokusebenza kwiindawo ezinobushushu obuphezulu ngaphandle kokulahlekelwa bubunzima okanye ukuguquguquka okukhulu.
3. Ukusebenza Okugqwesileyo Kokusika: Uyilo lwe-spiral groove lwee-twist drills lunegalelo ekusikeni isinyithi ngempumelelo ngelixa kunciphisa ukuqokelelana kwee-chip.
4. Umgangatho Woomatshini Othembekileyo: Iidrili zentsimbi ezijijekileyo ngesantya esiphezulu zihlala zibonelela ngemingxunya ejijekileyo esemgangathweni ophezulu enobukhulu obuchanekileyo kunye neendawo ezigudileyo.
Iintlobo ze-HSS esizisebenzisileyo kwiidrill zethu ze-Twist
Amanqanaba aphambili e-HSS esiwasebenzisayo ngala: M42, M35, M2, 4341, 4241.
Kukho umahluko phakathi kwazo, ikakhulu ngenxa yokwakheka kwazo ngamakhemikhali, ubulukhuni, uzinzo lobushushu kunye neendawo ezisetyenziswa kuzo. Nazi umahluko ophambili phakathi kwezi gredi ze-HSS:
1. I-M42 HSS:
I-M42 ine-7%-8% ye-cobalt (Co), i-8% ye-molybdenum (Mo) kunye nezinye ii-alloys. Oku kuyinika ukumelana okungcono kokurhawuzelelwa kunye nokuzinza kobushushu. I-M42 idla ngokuba nobunzima obuphezulu, kwaye ubunzima bayo be-rockwell yi-67.5-70 (HRC) obunokufezekiswa ngeendlela zonyango lobushushu.
2. I-M35 HSS:
I-M35 iqulethe i-4.5%-5% ye-cobalt kwaye ikwanokumelana okukhulu nokurhawuzelelwa kunye nokuqina kobushushu. I-M35 inzima kancinci kune-HSS eqhelekileyo kwaye ihlala igcina ubunzima obuphakathi kwe-64.5 kunye ne-67.59 (HRC). I-M35 ifanelekile ukusika izinto ezinamathelayo ezifana nentsimbi engagqwaliyo.
3. I-M2 HSS:
I-M2 inamanqanaba aphezulu e-tungsten (W) kunye ne-molybdenum (Mo) kwaye ineempawu ezilungileyo zokusika. Ubunzima be-M2 buhlala buphakathi kwe-63.5-67 (HRC), kwaye ifanelekile ekusetyenzisweni kweentsimbi ezifuna iimfuno eziphezulu.
4. 4341 HSS:
I-4341 HSS yintsimbi ekhawulezayo enomxholo we-alloy ophantsi kancinci xa kuthelekiswa ne-m2. Ubunzima buhlala bugcinwa bungaphezulu kwe-63 HRC kwaye bufanelekile kwimisebenzi yokusebenza yesinyithi ngokubanzi.
5. 4241 HSS:
I-4241 HSS ikwayi-HSS ene-alloy ephantsi equlethe izinto ezincinci zokudibanisa. Ubunzima buhlala buhlala malunga ne-59-63 HRC kwaye buhlala busetyenziswa ekusebenzeni nasekubholeni isinyithi ngokubanzi.
Ukukhetha uhlobo olufanelekileyo lwe-HSS kuxhomekeke kwiimfuno zakho ezithile zokusetyenziswa kunye nohlobo lwezinto eziza kucutshungulwa. Ukuqina, ukumelana nokukrweleka kunye nokuzinza kobushushu zezona zinto zibalulekileyo ekukhetheni.
