Guhitamo iburyo bugoretse bito kumushinga wawe bikubiyemo gusobanukirwa ibintu bitatu byingenzi: ibintu, gutwikira, hamwe nibintu bya geometrike.Buri kimwe muri ibyo bintu kigira uruhare runini mu mikorere no kuramba kwa bito bito.Hano reba neza uburyo bwo gufata icyemezo kibimenyeshejwe.
Ibikoresho
1. Icyuma cyihuta cyane (HSS):
Icyuma cyihuta cyane (HSS) cyagize uruhare runini mugukata ibikoresho mugihe kirenga ibinyejana byinshi, bihabwa agaciro kubikoresha byinshi kandi bihendutse.Imyitozo ya HSS izwiho guhuza byinshi, ikora neza hamwe na myitozo yombi y'intoki hamwe na platifike ihamye nka kanda.Inyungu yingenzi ya HSS nubushobozi bwayo bwo kongera gukarishya, kuzamura kuramba kwimyitozo no kuyigira amahitamo meza kubikoresho bya lathe.Byongeye kandi, HSS ifite amanota atandukanye, buri kimwe gifite ibice bitandukanye byibanze kugirango bihuze ibikenewe byihariye.Ubu bwoko butandukanye mubyiciro byibyuma byongera guhuza na HSS, bigahinduka ibintu byinshi kandi byingenzi mubikorwa bitandukanye byo gutunganya.
2. Cobalt HSS (HSSE cyangwa HSSCO):
Ugereranije na HSS gakondo, Cobalt HSS yerekana gukomera no kwihanganira ubushyuhe.Uku kuzamura mumitungo biganisha ku kunoza cyane abrasion kurwanya, bigatuma imyitozo ya HSSE iramba kandi ikora neza.Kwinjiza cobalt muri HSSE ntabwo bigira uruhare mu kongera imbaraga zo kurwanya abrasion ahubwo binongera ubuzima bwayo muri rusange.Nkinshi nka HSS isanzwe, bits ya HSSE igumana inyungu zo kongera gukarishye, ibyo bikaba byongera ubuzima bwabo bukoreshwa.Kubaho kwa cobalt muri HSSE bituma ibi bits bikwiranye cyane cyane nimirimo isabwa cyane yo gucukura aho kuramba no kurwanya abrase ari ngombwa.
3. Carbide:
Carbide nicyuma cya matrix igizwe, cyane cyane ikozwe muri tungsten karbide hamwe na binders zitandukanye.Irenze cyane HSS mubukomere, kwihanganira ubushyuhe, no kurwanya abrasion.Mugihe bihenze cyane, ibikoresho bya karbide biruta mubuzima no gukora umuvuduko.Bakenera ibikoresho kabuhariwe kugirango bongere gukarisha.
Igipfukisho
Imyitozo ya biti iratandukanye cyane kandi ihitamo ukurikije porogaramu.Dore muri make incamake kubintu bimwe bisanzwe:
1. Bidatwikiriwe (Bright):
Nibara risanzwe kuri HSS drill bits.Nibyiza kubikoresho byoroshye nka aluminiyumu hamwe nicyuma gito cya karubone, ibikoresho bidafunze nibyo bihendutse cyane.
2. Igipfukisho cya Oxide yirabura:
Itanga amavuta meza hamwe nubushyuhe burenze ibikoresho bidafunze, kuzamura ubuzima hejuru ya 50%.
3. Igikoresho cya Titanium Nitride (TiN):
Imyitozo ya Titanium ikozwe neza ikora neza mubihe byinshi byo gusaba bitewe nibikorwa byihariye biranga.Ubwa mbere, Yongera ubukana no kurwanya abrasion ikoresheje igifuniko, ituma biti biguma bikarishye mugihe ucukura ibikoresho bikomeye, kandi bigatanga ubuzima burebure.Ibi bits bigabanya guterana ubushyuhe no kongera ubushyuhe, byongera uburyo bwo guca mugihe urinda bito ubushyuhe bwinshi.Ibikoresho bya Titanium birakwiriye gukoreshwa mubikoresho byinshi, nk'ibyuma bitagira umwanda, aluminium n'ibiti, bigatuma biba byiza mu buhanga no mu rugo.Mubyongeyeho, ibi bits byinjira mubikoresho byihuse kandi bisukuye, bitanga ubuso bwiza.Mugihe imyitozo ya titanium ishobora gutwara amafaranga arenze imyitozo isanzwe, imikorere yabo myiza hamwe nubuzima burebure bituma bagaruka neza kubushoramari kubisabwa bisaba kurwanya abrasion nyinshi no gukata neza.
4. Igikoresho cya Aluminium Titanium Nitride (AlTiN):
Ubwa mbere, AlTiN itwikiriye irwanya ubushyuhe bukabije, ibafasha kuba indashyikirwa mugukata byihuse no gutunganya amavuta yubushyuhe bwo hejuru.Icya kabiri, iyi shitingi itezimbere cyane kurwanya abrasion kandi ikagura ubuzima bwibikoresho, cyane cyane iyo ikora ibikoresho bikomeye nkibyuma bitagira umwanda, titanium alloys hamwe na nikel ishingiye kuri nikel.Byongeye kandi, igifuniko cya AlTiN kigabanya ubushyamirane hagati ya biti ya drill hamwe nakazi kakazi, kunoza imikorere yimashini no gufasha kugera kubutaka bworoshye.Ifite kandi imbaraga nziza zo kurwanya okiside hamwe n’imiti ihamye, ikabasha gukomeza imikorere mu bikorwa bibi.Muri rusange, imyitozo ya AlTiN ikozwe neza muburyo bwihuse bwo gukoresha imashini yihuta, kandi ikwiranye cyane no gukoresha ibikoresho bikomeye bitera ikibazo imyitozo isanzwe.
Ibiranga geometrike
1. Uburebure:
Ikigereranyo cy'uburebure na diameter kigira ingaruka zikomeye.Guhitamo imyitozo ifite uburebure bwimyironge ihagije yo kwimura chip hamwe na minisiteri ntoya irashobora kongera ubukana nubuzima bwibikoresho.Uburebure bwimyironge idahagije bushobora kwangiza bito.Hariho uburebure butandukanye bwo guhitamo ku isoko.Uburebure bumwe busanzwe ni Jobber, kunangira, DIN 340, DIN 338, nibindi.
2. Inguni y'imyitozo:
Inguni ya 118 ° isanzwe kubutare bworoshye nkicyuma gito cya karubone na aluminium.Mubisanzwe idafite ubushobozi bwo kwikenura, ikenera umwobo.Inguni ya 135 °, hamwe nimikorere yayo yo kwikenura, ikuraho igikenewe cyo gutandukanya umwobo, ikiza igihe gikomeye.
Mu gusoza, guhitamo iburyo bwimyitozo ya biti bikubiyemo kuringaniza ibisabwa mubikoresho birimo gucukurwa, igihe wifuza cyo kubaho no gukora bito, nibisabwa byihariye byumushinga wawe.Gusobanukirwa nibi bintu bizagufasha guhitamo imyitozo ngirakamaro kandi ikora neza kubyo ukeneye.
