Muri iki gihe, hari ubwoko bwinshi bwibiti byo gukora ibiti kuburyo abakiriya benshi batazi ubwoko aribwo bakeneye.Iki gice kizaguha ibitekerezo bimwe.
Imyitozo ya Twist.: Imyitozo ya Twist ifite ibyuma bya silindrike hamwe ninama.
Ingano yimyitozo ngororamubiri myinshi nini nini nka shanki.Imirongo ibiri yimyironge (rimwe na rimwe bita imiyoboro ya chip) ikora ikoresheje bibiri bya gatatu by'uburebure bwayo, ikazunguruka ku nkombe nk'imirongo iri ku giti cyo kogosha.
Igiciro cyimyitozo ngororamubiri ihendutse kuruta ibindi bits, ariko umwobo wibice byakozwe ntabwo ari ukuri.Bikoreshwa inshuro nyinshi hamwe na myitozo yo hasi kugirango harebwe ukuri. Ukoresheje umubiri wibyuma, imyitozo ya twist ntishobora kwihanganira ubushyuhe bwinshi, bityo ntushobora kuyikoresha n'umuvuduko wo kuzunguruka.Imikorere yawe yo gutunganya nayo izagarukira.
Imyitozo ya Twist irakwiriye cyane kubikorera ku giti cyabo cyangwa abakoresha ibikoresho byabo ntibisubira inyuma.
Spade Bits.Ibi bits bisa nkizina ryabo risobanura: buri cyuma cyuma kirangirana nicyuma.Isuka iringaniye hamwe ningingo ityaye hagati.Iyi ngingo ikora nk'ubuyobozi bwo guhuza umwobo no kuyobora icyerekezo, ariko ibyinshi mubucukuzi bikorwa muburyo bwo gutema ibiti ku rutugu.
Bitewe nuburyo bworoshye bwibikoresho bya spade, ntabwo bifite ubushobozi bwiza bwo kwimura chip.Muri icyo gihe, kubera igishushanyo cyindege yo gukata, imikorere yo gukubita spade bito irakennye cyane.
Rero, kubwukuri, bits ya spade iruta imyitozo ya twist.Ariko imikorere yayo yo gutunganya igomba kuba mbi mumyitozo yose.
Imyitozo ya Twist irakwiriye cyane kubikorera ku giti cyabo bakoresha ibikoresho byamashanyarazi.
Imyitozo ya Brad Point: Kugirango uhuze ibikenewe byo gutunganywa byihuse, brad point drill bit yavumbuwe.Brad point drill bit ihuza ibyiza bya spade bit na twist drill.Hano hari umwitozo hagati nkuyobora, kandi hariho impande ebyiri zo gukata kumpande zombi kugirango tumenye diameter yumwobo.Kandi brad point drill bits nayo ifite imiyoboro izenguruka kugirango yongere ubushobozi bwo gucukura.Igishushanyo cya shank nacyo ni ukureba ko gishobora gukoreshwa neza kumashini za CNC.
Kandi twateje imbere kandi dutangiza ubwoko butandukanye bwa brad point drill bits kubakiriya bakoresha mubihe bitandukanye.ZY drill bits ikwiranye no gukora umuvuduko muke (1000-3000S / min).Imyitozo ya KJ-2 ikwiranye no gukora imashini yihuta (2000-4000S / min).Imyitozo ya KJ-1 ikwiranye no gukora umuvuduko mwinshi (3000-6000S / min).
Brad point drill bits nuguhitamo kwiza kubakiriya bafite imashini za CNC.
Imyitozo ya Countersink.Ibikoresho bikozwe byumwihariko bigurishwa bitobora umwobo wicyuma cyibiti.Imyitozo ya Countersink ifite imyirondoro ihuza imiterere yimigozi: Imyobo batobora taper gahoro gahoro ku burebure bwa screw, hanyuma ikaguka, ikemerera imitwe yimigozi gushyirwaho (countersunk) mukibiti.Birakwiriye gukora ibiti bya CNC; imashini.
Forstner Bits.Ubu bwenge bits burobora umwobo hamwe nuburinganire.Aho kugira isonga ihanamye ikurikirwa no gukata impande zose, biti ya Forstner iyobowe nuruziga.Imiyoboro iri mu myitozo ikuraho umwobo wa chipi n'umukungugu.Umwobo wavuyemo ufite epfo na ruguru iringaniye, yangijwe gusa na 1/32 cya santimetero hagati aho intangiriro yo gutangira imyitozo iherereye.
Forstner bits ihenze cyane, kandi ntabwo ikenewe kubikorwa byinshi.Nyamara, ni ngombwa kubandi, nko gushiraho impeta zigomba gusubizwa mu mwobo uzengurutswe unyuze hagati yinzu yumuryango..
