Nigute wahitamo drill?

Uyu munsi, nzasangira uburyo bwo guhitamo drill bit kugeza kuri bitatu byibanze byadrill bit, ni: ni: ni: Ibikoresho, gutwikira na geometrike.

Nigute wahitamo ibikoresho bya drill

Ibikoresho birashobora kugabanywa muburyo butatu: Ibyuma Byihuta, Cobalt-irimo steel yihuta yihuta na karbide ikomeye.

Ibyuma Byinshi (HSS):

Ibyuma Byihuta kuri ubu ni ibintu bikoreshwa cyane kandi bihendutse byo gukata ibikoresho. Icyuma gitugu cyihuta cyihuta ntigikoreshwa gusa kumaboko yamashanyarazi gusa, ariko nanone mubidukikije hamwe no guturika neza nkimashini zo gucukura. Indi mpamvu yo kuramba kwimiterere yihuta irashobora kuba nkigikoresho gikozwe mubyuma byihuse gishobora kuba ubutaka inshuro nyinshi. Bitewe nigiciro gito, ntabwo ikoreshwa gusa yo gusya muri drill bits, ariko nayo ikoreshwa cyane muguhindura ibikoresho.

Cobalt yihuta yihuta (HSSCO):

Codalt-irimo ibyuma byihuta bigira ubukana bwiza nuburuso butukura kuruta ibyuma byihuta, kandi ubwitonzi bugenda kandi buzamura ubukana no gutamba umwanya wabyo. Kimwe no kwihuta-kwihuta: birashobora gukoreshwa mugutezimbere inshuro nyinshi.

 

Carbide (Carbide):

CARITIDE CARBIDE nigikoresho gishingiye ku ibyuma. Muri bo, karbide ya Tungsten ikoreshwa nka matrix, hamwe nibikoresho bimwe byibindi bikoresho bikoreshwa mugihe bibunze ko byangijwe nuruhererekane rwibintu bitangaje nkibishyushye. Ugereranije n'ibyuma byihuta cyane mubijyanye no gukomera, gukomera gutukura, kwambara kurwanya, nibindi, ibiciro byibikoresho bya sima nabyo birahagije kuruta ibyuma byihuta. Carbide ifite ibyiza byinshi kuruta ibikoresho byabanjirije ibikoresho mubijyanye nubuzima bwibikoresho no gutunganya. Mu gusya inshuro nyinshi ibikoresho, ibikoresho byo gusya babigize umwuga birakenewe.

Nigute wahitamo imyitozo

Gutwara birashobora gushyirwa muburyo butandukanye muburyo butanu bukurikira ukurikije urugero rwibikoreshwa.

Ntiyamenyekanye:

Ibyuma byafunguye ni bihendutse kandi mubisanzwe bikoreshwa mugukoresha imashini ibikoresho byoroheje nka aluminiyumu alloys hamwe nubyuma bito.

IHURIRO RY'UMUKARA:

Ikirangantego cya Okiside irashobora gutanga amavuta meza kuruta ibikoresho byanduye, kandi nibyiza mubijyanye na okiside no kurwanya ubushyuhe, kandi birashobora kongera ubuzima bwa serivisi kurenza 50%.

Titanium Nitride yabereye:

Titanium Nitride nigikoresho gikunze kugaragara kandi ntabwo ikwiriye gutunganya ibikoresho byo gutunganya hamwe nubushyuhe bukabije.

Titanium Carbonitride:

Titanium Carbone yatunganijwe kuva Titanium Nitride kandi ifite ubushyuhe bwo hejuru kandi bwambara, mubisanzwe ibara ry'umuyugubwe cyangwa ubururu. Byakoreshejwe Kuri Machise Abakozi bakorerwa ibyuma mumahugurwa ya HaAs.

Aluminium Nitride Titanium indege:

Aluminum Titanium Nitride irwanya ubushyuhe bwo hejuru kuruta amatara yose yavuzwe haruguru, bityo irashobora gukoreshwa mubidukikije byo hejuru. Kurugero, gutunganya supellows. Birakwiriye kandi gutunganya ibyuma n'ibiti bidafite ishingiro, ariko kubera ibintu birimo aluminium, bizabaho iyo gutunganya aluminiyumu, bityo wirinde gutunganya ibikoresho birimo aluminium.

Drill bit geometrie

Ibiranga geometrike birashobora kugabanywamo ibice 3 bikurikira:

Uburebure

Ikigereranyo cyuburebure kuri diameter cyitwa kabiri diameter, kandi gito diameter inshuro ebyiri, ibyiza bikomeye. Guhitamo Imyitozo hamwe nuburebure bwuburebure bwo gukuraho Chip kandi uburebure buke burenze urugero burashobora kuzamura imitako mugihe cyo kuvura mugihe cyo gufata, bityo bikongera ubuzima bwa serivisi. Uburebure budahagije bushobora kwangiza imyitozo.

Gukora inguni

Inguni yimodoka ya 118 ° birashoboka ko ari rusange mumashini kandi akenshi ikoreshwa mubyuma byoroheje nkicyuma cyoroheje na aluminiyumu. Igishushanyo mbonera cyubusanzwe ntabwo ari ukurwanya, bivuze ko byanze bikunze kugirango ushire imbere umwobo ubanza. 135 ° Gukora inguni yinguzanyo mubisanzwe ifite imikorere yo kwikuramo. Kubera ko bidakenewe kwihitiramo umwobo wo hagati, ibi bizatuma bitari ngombwa ko yirukana umwobo utandukanya ukundi, bityo ukuze igihe kinini.

Helix Inguni

Umuriro wa Helix wa 30 ° ni amahitamo meza kubikoresho byinshi. Ariko kubidukikije bisaba kwimuka neza na chip yibye hamwe nigituba gikomeye, imyitozo ifite angle ntoya ya Helix irashobora gutoranywa. Kubikoresho bigoye-kuri-imashini nkicyuma kitagira ingano, igishushanyo mbonera cya Helix nini gishobora gutoranywa kohereza torque.
