Nigute ushobora guhitamo iburyo bwihuta bwibyuma bito: ibintu bifatika byibintu byiza

Nka gikoresho cyingirakamaro mubikorwa byo gukora inganda no gutunganya neza, ubwiza bwibikoresho byihuta byihuta (HSS Drill Bits) bigira ingaruka kuburyo butaziguye kumurimo, gutunganya neza nubuzima bwibikoresho. Nyamara, mubintu byinshi byihuta byuma byuma bito ku isoko, uburyo bwo guhitamo ibikoresho byiza nubuziranenge ni ikibazo buri muguzi nuwabikoze agomba guhura nabyo. Iyi ngingo iragaragaza ibintu biranga ibintu byihuta byuma byuma byihuta, ibintu bigira ingaruka nziza, nuburyo bwo guhitamo neza ukurikije ibyo ukeneye.

Ibikoresho bigize ibyuma byihuta byuma bits
Ibyuma byihuta byimyitozo isanzwe ikozwe mubyuma byihuta (HSS). Ibi byuma bivanze bifite ubukana bwinshi, birwanya kwambara cyane hamwe nubushyuhe buhebuje, bityo birashobora gukomeza gukora neza mugihe cyo gukora byihuse. Amavuta avanze yibikoresho byihuta byimyitozo ya bits ni urufunguzo rwo kumenya ubuziranenge n'imikorere.

Ibikoresho bisanzwe byihuta byibyuma birimo:

M2 ibyuma byihuta
M2 nibikoresho bisanzwe byihuta cyane byuma, bikwiranye nuburyo butandukanye bwo gucukura. Ubusanzwe irimo molybdenum, tungsten hamwe na cobalt nkeya, ifite kwihanganira kwambara no gukomera, kandi ikwiriye gucukura ibyuma bisanzwe nka aluminium, umuringa, nicyuma.

M35 Icyuma cyihuta
M35 ifite ubukana bwinshi nubushyuhe bwo hejuru kurenza M2, kandi irakwiriye cyane cyane mubisabwa bisaba gutunganya ibyuma bikomeye (nkibyuma bitagira umwanda nicyuma kivanze). Ibirungo byinshi bya cobalt biri muri M35 (hafi 5%) bitezimbere cyane ubushyuhe bwabyo kandi byongera ubuzima bwa serivisi.

M42 Icyuma cyihuta
M42 ishimangira cyane kwambara cyane no kurwanya ubushyuhe bwo hejuru, kandi ikoreshwa cyane mugucukura ibyuma bikomeye hamwe na alloys. Ibirimo bya cobalt biri hejuru ya 8%, bishobora kwihanganira ubushyuhe bwo hejuru bwo kugabanuka.

Ibintu bigira ingaruka kumiterere yimyitozo yihuta
Muguhitamo imyitozo yihuta yicyuma, ni ngombwa kumva ibintu bigira ingaruka nziza. Hano hari amahame yingenzi yubuziranenge:

Kuvanga ibihimbano hamwe nibikorwa
Ibikoresho bivangwa nubushyuhe bwo gutunganya ibyuma byihuta byimyitozo niyo shingiro ryo kumenya imikorere yabyo. Kurugero, ibintu bitandukanye hamwe nuburyo bwo kuvura ibikoresho bya M2, M35 na M42 bizagira ingaruka ku buryo butaziguye ubukana, ubukana no kwambara birwanya imyitozo. Imyitozo yo mu rwego rwohejuru isanzwe ikorwa nubushyuhe bukabije kugirango habeho ituze ryubushyuhe bwinshi no kuzunguruka byihuse.

Uburyo bwiza kandi bwo gukora
Imyitozo ihanitse cyane irashobora kwemeza neza no kurangiza neza gucukura. Mugihe uhisemo, hagomba kwitabwaho cyane kubuvuzi bwa biti bito, nko gusya neza, igishushanyo mbonera cya helix, imiterere ya point point, nibindi, bigena ituze hamwe nubwiza bwimyanda mugihe cyo gutema.

Ikoreshwa rya tekinoroji
Mu myaka yashize, ikoreshwa rya tekinoroji yo gutwikira ryatanze amahirwe menshi yo kunoza imikorere yimyanda yihuta. Ipitingi isanzwe irimo titanium (TiN), titanium nitride (TiAlN), nibindi. Iyi myenda irashobora kunoza neza ubukana, kwambara no kurwanya ruswa ya biti ya myitozo, ikongerera igihe cyumurimo wa biti, kandi irashobora gukora mubushyuhe bwinshi.

Shushanya bito
Ibyuma byujuje ubuziranenge byihuta byuma bitsindagira akenshi bifite ibishushanyo mbonera, cyane cyane muburyo bwa helix, kuyobora inguni no guca imiterere. Igishushanyo gishyize mu gaciro kirashobora kwemeza ituze, kugabanya imikorere no gucukura neza mugihe cyo gucukura ibikoresho bitandukanye.

Nigute ushobora guhitamo ibyuma byihuta byihuta bito bito
Guhitamo ibyuma byihuta byihuta bito ntabwo bishingiye kubiciro gusa, ahubwo inita kubikorwa bikenewe. Ibikurikira nibintu byinshi byingenzi muguhitamo:

Ubwoko bwibikoresho
Ibikoresho bitandukanye bifite ibisabwa bitandukanye kubitobora. Kubyuma byoroshye (nka aluminium na muringa), imyitozo ya M2 yihuta yihuta irashobora guhaza ibikenewe. Kubikoresho byuma bikomeye (nkibyuma bidafite ingese nicyuma kivanze), birasabwa guhitamo imyitozo ya M35 cyangwa M42 yihuta cyane, ishobora gutanga ubushyuhe bwinshi kandi ikarwanya kwambara.

Gucukura diameter n'uburebure
Ingano nuburebure bwimyitozo bizagira ingaruka kubisobanuro byimyitozo. Mubisanzwe, umwobo munini wa diameter usaba imyitozo yo mu rwego rwo hejuru kugirango ukomeze gukata neza. Byongeye kandi, ubujyakuzimu buzagira ingaruka no ku miterere yimiterere yimyitozo, nkimyitozo ndende, imyitozo yoroheje, nibindi.

Ibidukikije bikora hamwe nuburyo bwo guca ibintu
Kumuvuduko mwinshi, umutwaro mwinshi cyangwa ibidukikije byo hejuru, ni ngombwa cyane guhitamo imyitozo ya HSS hamwe nubushyuhe bwo hejuru hamwe no kwihanganira kwambara. Imyitozo ikozweho irakwiriye cyane cyane kugabanya umuvuduko mwinshi hamwe nubushyuhe bwo hejuru, bushobora kongera ubuzima bwa serivisi.

Ingengo yimari no guhitamo ibirango
Itandukaniro ryibiciro byimyitozo yihuta yihuta kumasoko ni nini. Nigute ushobora kubona uburinganire hagati yimikorere nigiciro ni ikintu cyingenzi muguhitamo. Guhitamo ikirango gifite izina ryiza birashobora kwemeza ubuziranenge na nyuma yo kugurisha ibicuruzwa. Ibirangantego bizwi mubisanzwe bitanga ubuziranenge bwiza hamwe nubufasha bwuzuye bwa tekiniki.

Kubungabunga no gufata neza ibyuma byihuta byimyitozo
Ibyuma byujuje ubuziranenge byihuta byimyitozo isanzwe ifite igihe kirekire cyo gukora, ariko mugihe cyo kuyikoresha, kuyifata neza no kuyifata neza nayo ishobora kongera igihe cyakazi:

Isuku isanzwe: Komeza imyitozo isukuye kandi ukureho ibyuma byakozwe mugihe cyo gucukura kugirango wirinde kugira ingaruka nziza.

Gukonjesha mu buryo bushyize mu gaciro: Ukoresheje gukata amazi cyangwa gukonjesha, cyane cyane mugutunganya ibikoresho bifite imbaraga nyinshi, birashobora gukumira neza ubushyuhe no kongera ubuzima bwimyitozo.

Reba imyenda: Buri gihe ugenzure inkombe nubuso bwimyitozo ya bito, hanyuma ukarishe cyangwa usimbuze imyanda yangiritse mugihe.

Incamake
Ibyuma byihuta byibyuma byahindutse igikoresho cyingirakamaro mubikorwa byinganda kubera imikorere myiza kandi ikoreshwa cyane. Mugusobanukirwa ibintu bifatika, ibipimo byubuziranenge, nuburyo bwo guhitamo bikwiye ukurikije akazi, abakoresha barashobora kunoza neza gucukura no gutunganya neza. Haba mugutunganya ibyuma, kubaka cyangwa gukora neza, guhitamo neza ibyuma byihuta byihuta bito nurufunguzo rwo kuzamura ireme ryakazi no kugabanya ibiciro.
