Niki HSS Twist Drill Bit?
HSS twist drill ni ubwoko bwibikoresho byo gucukura bikozwe mubyuma byihuta bikoreshwa mugutunganya ibyuma.HSS nicyuma kidasanzwe kivanze gifite imbaraga zo kurwanya abrasion, guhagarara neza kwubushyuhe, hamwe no gukata ibintu, bigatuma biba byiza mubikorwa byo gukora ibyuma nko gucukura.Imyitozo igoretse (izwi kandi nka auger cyangwa spiral flute drill) ni imyitozo ifite imyironge ihanamye ituma gukata ibyuma bisohoka mu mwobo wihuse, kugabanya ubukana nubushyuhe mugihe cyo gucukura no kunoza imikorere.Igishushanyo mbonera cya HSS cyimyitozo ituma gikwiranye nibikoresho byinshi byuma bitandukanye, birimo ibyuma, aluminium, umuringa na alloys, nibindi ndetse no gutunganya ubwoko bwibiti.
Ibiranga Umuvuduko Wihuse Wibyuma Byimyitozo
1. Kurwanya Abrasion Kurwanya: Ibikoresho byihuta byihuta byerekana imbaraga zo kurwanya abrasion, bigatuma impande zo gutema ziguma zikarishye mugihe kirekire.
2. Ubushyuhe bukabije: Ibyuma byihuta birashobora gukorera ahantu h’ubushyuhe bwo hejuru nta gutakaza gukomeye cyangwa guhinduka.
3. Igikorwa cyiza cyo Gutema Cyiza: Igishushanyo mbonera cyimyitozo ngororamubiri kigira uruhare mukugabanya ibyuma neza mugihe bigabanya kwirundanya kwa chip.
4. Imashini yizewe yizewe: Imyitozo yihuta yihuta yimyitozo isanzwe itanga umwobo wo murwego rwohejuru wacukuwe ufite ibipimo bifatika hamwe nubuso bworoshye.
Ubwoko bwa HSS Twakoresheje Kumyitozo Ya Twist
Ibyiciro byingenzi bya HSS dukoresha ni: M42, M35, M2, 4341, 4241.
Hariho itandukaniro hagati yabo, cyane cyane bijyanye nimiterere yabyo, ubukana, ubushyuhe bwumuriro hamwe nibisabwa.Hasi hari itandukaniro nyamukuru hagati yaya manota ya HSS:
1. M42 HSS:
M42 irimo 7% -8% cobalt (Co), 8% molybdenum (Mo) nibindi bivangwa.Ibi biratanga uburyo bwiza bwo kurwanya abrasion hamwe nubushyuhe bwumuriro.M42 mubusanzwe ifite ubukana buhanitse, kandi ubukana bwayo ni 67.5-70 (HRC) bushobora kugerwaho nubuhanga bwo kuvura ubushyuhe.
2. M35 HSS:
M35 irimo 4.5% -5% cobalt kandi ifite kandi imbaraga zo kurwanya abrasion hamwe nubushyuhe bwumuriro.M35 iragoye gato kurenza HSS isanzwe kandi mubisanzwe ikomeza ubukana bwa betweeb 64.5 na 67.59 (HRC).M35 ibereye gukata ibikoresho bifatanye nkibyuma bidafite ingese.
3. M2 HSS:
M2 irimo urwego rwo hejuru rwa tungsten (W) na molybdenum (Mo) kandi ifite ibyiza byo gukata.Ubukomere bwa M2 mubusanzwe buri hagati ya 63.5-67 (HRC), kandi burakwiriye gutunganya ibyuma bikenera ibisabwa cyane.
4. 4341 HSS:
4341 HSS nicyuma cyihuta gifite ibyuma byo hasi cyane ugereranije na m2.Ubukomezi bugumaho hejuru ya 63 HRC kandi burakwiriye kubikorwa rusange byicyuma.
5. 4241 HSS:
4241 HSS nayo ni amavuta make ya HSS irimo ibintu bike bivanga.Ubukomezi bugumaho muri 59-63 HRC kandi mubisanzwe bikoreshwa mubyuma rusange bikora no gucukura.
Guhitamo icyiciro gikwiye cya HSS biterwa nibisabwa byihariye hamwe nubwoko bwibikoresho bigomba gutunganywa.Gukomera, kurwanya abrasion hamwe nubushyuhe bwumuriro nibintu byingenzi muguhitamo.
