HSS Twist Drill Bit ni iki?
HSS twist drill ni ubwoko bw'igikoresho cyo gucukura gikozwe mu cyuma cyihuta gikoreshwa mu gutunganya ibyuma. HSS ni icyuma cyihariye gifite ubushobozi bwo kudashwanyagurika neza, kudahindagurika k'ubushyuhe, no gukata, bigatuma kiba cyiza cyane mu mirimo yo gukora ibyuma nko gucukura. Icukura ryijimye (rizwi kandi nka auger cyangwa spiral flute drill) ni icukura rifite ibyuma bya helical flute byemerera gukata ibice bisohoka mu mwobo w'icukura vuba, bigabanya gushya no gushyuha mu gihe cyo gucukura no kunoza imikorere yo gucukura. Imiterere y'icukura rya HSS twist drills ituma rikoreshwa mu bikoresho bitandukanye by'icyuma, harimo icyuma, aluminiyumu, umuringa n'ibindi, ndetse no mu gutunganya ubwoko bw'ibiti.
Ibiranga imashini zikora imashini zihindura ibyuma zihuta cyane
1. Ubudahangarwa ku bwinshi: Ibikoresho by'icyuma byihuta cyane bigaragaza ubudahangarwa bwiza, bigatuma impande zo gutema ziguma zityaye igihe kirekire.
2. Guhagarara neza mu bushyuhe: Icyuma cyihuta cyane gishobora gukora ahantu hari ubushyuhe bwinshi nta gutakaza uburemere cyangwa guhinduka gukomeye gukabije.
3. Umusaruro mwiza wo gukata: Imiterere y'imirongo izunguruka y'imashini zizunguruka igira uruhare mu gukata neza icyuma ariko ikagabanya kwirundanya kw'udupira.
4. Ubwiza bw'imashini bwizewe: Imashini zikora imashini zihuta cyane zitanga imyobo myiza cyane ifite ingano nyayo n'ubuso bworoshye.
Ubwoko bwa HSS twakoresheje mu kwimenyereza twizunguza
Ibyiciro by'ingenzi bya HSS dukoresha ni: M42, M35, M2, 4341, 4241.
Hari itandukaniro hagati yabyo, ahanini rijyanye n'imiterere yabyo ya shimi, ubukana bwabyo, ubushyuhe buhamye n'aho bikoreshwa. Dore itandukaniro ry'ingenzi riri hagati y'ibi byiciro bya HSS:
1. M42 HSS:
M42 irimo 7%-8% ya kobalti (Co), 8% ya molybdenum (Mo) n'izindi alloys. Ibi biyiha ubushobozi bwo kurwanya kwangirika no kudahinduka kw'ubushyuhe. M42 ubusanzwe ifite ubukana bwinshi, kandi ubukana bwayo bwa rockwell ni 67.5-70 (HRC) bushobora kugerwaho hakoreshejwe uburyo bwo kuvura ubushyuhe.
2. M35 HSS:
M35 irimo 4.5%-5% ya kobalti kandi ifite ubushobozi bwo kurwanya kwangirika no kudahinduka kw'ubushyuhe. M35 irakomeye gato kurusha HSS isanzwe kandi akenshi igumana ubukana bwa 64.5 na 67.59 (HRC). M35 ikwiriye gukatwa ibikoresho bifatana nk'icyuma kidashonga.
3. M2 HSS:
M2 irimo urugero rwo hejuru rwa tungsten (W) na molybdenum (Mo) kandi ifite ubushobozi bwo gukata neza. Ubukana bwa M2 busanzwe buri hagati ya 63.5-67 (HRC), kandi ikwiriye gukoreshwa mu gukora ibyuma bikeneye ibisabwa byinshi.
4. 4341 HSS:
4341 HSS ni icyuma cyihuta cyane gifite ingano ntoya y'icyuma ugereranyije na m2. Ubukana bwacyo muri rusange buguma hejuru ya HRC 63 kandi bukwiriye imirimo rusange y'icyuma.
5. 4241 HSS:
4241 HSS na yo ni HSS yo mu bwoko bwa alloy nke irimo ibintu bike byo gusya. Ubukana muri rusange bugumana hafi ya 59-63 HRC kandi bukunze gukoreshwa mu gukora no gucukura ibyuma muri rusange.
Guhitamo urwego rukwiye rwa HSS biterwa n'ibyo ukeneye mu ikoreshwa ryawe n'ubwoko bw'ibikoresho bigomba gutunganywa. Ubukomere, kudashwanyagurika no kudahindagurika kw'ubushyuhe ni byo bintu by'ingenzi mu guhitamo.
