HSS Twist Drill Bit ke Eng?
HSS twist drill ke mofuta oa sesebelisoa sa ho phunya se entsoeng ka tšepe ea lebelo le phahameng e sebelisetsoang ho lokisa tšepe. HSS ke tšepe e khethehileng ea alloy e nang le khanyetso e ntle ea abrasion, botsitso ba mocheso, le thepa ea ho seha, e etsang hore e be e loketseng bakeng sa mesebetsi ea tšepe e kang ho cheka. Twist drill (eo hape e tsejoang e le auger kapa spiral flute drill) ke mochini o nang le lekolilo la helical le lumellang li-cuttings hore li tsoe ka lesoba la ho phunya kapele, ho fokotsa likhohlano le mocheso nakong ea ho cheka le ho ntlafatsa bokhoni ba ho cheka. Moqapi oa li-drill tsa HSS twist o li etsa hore li tšoanelehe bakeng sa mefuta e mengata e fapaneng ea lisebelisoa tsa tšepe, ho akarelletsa le tšepe, aluminium, koporo le li-alloys, joalo-joalo hammoho le machining a mofuta oa lehong.
Litšobotsi Tsa Lits'oants'o Tsa Litšepe Tsa Lebelo Le Leholo
1. High Abrasion Resistance: Lisebelisoa tsa tšepe tse phahameng ka lebelo le phahameng li bonts'a khanyetso e ntle ea abrasion, e lumellang likarolo tsa ho itšeha hore li lule li le bohale ka nako e telele.
2. Botsitso bo Phahameng ba Mocheso: Tšepe e phahameng ka potlako e ka sebetsa libakeng tse phahameng tsa mocheso ntle le tahlehelo e kholo ea ho thatafala kapa ho senyeha.
3. Ts'ebetso e Ntle e Ntle ea ho Seha: Moralo oa spiral groove oa li-drill tse sothang o kenya letsoho ho seha tšepe ka katleho ha o ntse o fokotsa ho bokellana ha chip.
4. Boleng bo Tšepahalang ba Machining: Lisebelisoa tsa tšepe tse sothang ka lebelo le phahameng hangata li fana ka likoti tse phuntsoeng tsa boleng bo holimo tse nang le litekanyo tse nepahetseng le libaka tse boreleli.
Mefuta ea HSS eo re e Sebelisang Bakeng sa Lits'oants'o Tsa Rona tsa Twist
Limaraka tse kholo tsa HSS tseo re li sebelisang ke: M42, M35, M2, 4341, 4241.
Ho na le phapang pakeng tsa bona, haholo-holo e amanang le lik'hemik'hale tsa bona, boima, botsitso ba mocheso le libaka tsa kopo. Ka tlase ke liphapang tse kholo lipakeng tsa limaraka tsena tsa HSS:
1. M42 HSS:
M42 e na le 7% -8% cobalt (Co), 8% molybdenum(Mo) le lisebelisoa tse ling. Sena se e fa khanyetso e ntle ea abrasion le botsitso ba mocheso. M42 hangata e na le boima bo phahameng, 'me boima ba eona ba rockwell ke 67.5-70(HRC) e ka finyelloang ka mekhoa ea phekolo ea mocheso.
2. M35 HSS:
M35 e na le 4.5% -5% cobalt hape e na le khanyetso e kholo ea abrasion le botsitso ba mocheso. M35 e thata hanyenyane ho feta HSS e tloaelehileng 'me hangata e boloka boima ba betweeb 64.5 le 67.59(HRC). M35 e loketse ho seha lisebelisoa tse khomarelang tse kang tšepe e sa hloekang.
3. M2 HSS:
M2 e na le maemo a phahameng a tungsten (W) le molybdenum (Mo) mme e na le thepa e ntle ea ho itšeha. Ho thatafala ha M2 hangata ho ka har'a 63.5-67 (HRC), 'me e loketse ho etsoa ha litšepe tse hlokang litlhoko tse phahameng.
4. 4341 HSS:
4341 HSS ke tšepe e lebelo le holimo e nang le alloy content hanyenyane ho latela m2. Hangata boima bo bolokiloe ka holimo ho 63 HRC 'me bo loketse mesebetsi e tloaelehileng ea tšepe.
5. 4241 HSS:
4241 HSS hape ke motsoako o tlase oa HSS o nang le likarolo tse nyane tsa alloying. Ho thatafala ka kakaretso ho bolokoa ho pota 59-63 HRC 'me hangata e sebelisetsoa ho sebetsa le ho cheka tšepe ka kakaretso.
Ho khetha kereiti e nepahetseng ea HSS ho ipapisitse le litlhoko tsa hau tse ikhethileng tsa kopo le mofuta oa thepa e lokelang ho sebetsoa. Ho thatafala, ho hanyetsa abrasion le botsitso ba mocheso ke lintlha tse ka sehloohong tsa khetho.
