Ni gute wahitamo igikoresho cyo gucukura?

Uyu munsi, ndabagezaho uburyo bwo guhitamo igikoresho cyo gucukura hakoreshejwe ibintu bitatu by'ibanze byaagace ko gucukura, aribyo: ibikoresho, irangi n'imiterere y'ubuso.

Uburyo bwo guhitamo ibikoresho by'imashini yo gucukura

Ibikoresho bishobora kugabanywamo ubwoko butatu: icyuma cyihuta cyane, icyuma cyihuta kirimo kobalti na karubide ikomeye.

Icyuma cyihuta cyane (HSS):

Icyuma cyihuta cyane ni cyo gikoreshwa cyane kandi gihendutse mu gukata. Igice cy'icyuma cyihuta cyane gishobora gukoreshwa atari ku mashini zikoresha amashanyarazi gusa, ahubwo no mu bidukikije bifite umutekano mwiza nko mu mashini zicukura. Indi mpamvu ituma icyuma cyihuta cyane kiramba ni uko igikoresho gikozwe mu byuma byihuta cyane gishobora gusya kenshi. Bitewe n'igiciro cyacyo gito, ntigikoreshwa gusa mu gusya mo uduce duto, ahubwo kinakoreshwa cyane mu gucura ibikoresho.

Ibyuma bikoresha umuvuduko mwinshi bya Cobalt (HSSCO):

Icyuma cyihuta cyane kirimo Cobalt gifite ubukana bwiza n'ubukana butukura kurusha icyuma cyihuta cyane, kandi kwiyongera k'ubukana nabyo byongera ubushobozi bwacyo bwo kudashira, ariko icyarimwe bigabanya ubukana bwacyo. Kimwe n'icyuma cyihuta cyane: gishobora gukoreshwa mu kunoza umubare w'inshuro hakoreshejwe uburyo bwo gusya.

 

Karubide (CARBIDE):

Karubide ikoze muri sima ni ibikoresho bikozwe mu cyuma. Muri byo, karubide ya tungsten ikoreshwa nk'umusemburo, naho bimwe mu bikoresho by'ibindi bikoresho bikoreshwa nk'icyuma gifata ibintu kugira ngo gikoreshwe mu buryo butandukanye nko gukanda bushyushye bwa isostatic. Ugereranyije n'icyuma cyihuta mu bijyanye n'ubukomere, ubukomere butukura, kudashira, nibindi, hari iterambere rikomeye, ariko ikiguzi cy'ibikoresho bya karubide ikoze muri sima nacyo gihenze cyane kuruta icyuma cyihuta. Karubide ifite ibyiza byinshi kuruta ibikoresho byakoreshejwe mbere mu bijyanye n'igihe cy'ibikoresho n'umuvuduko wo kubitunganya. Mu gusya ibikoresho kenshi, hakenewe ibikoresho by'umwuga byo gusya.

Uburyo bwo guhitamo irangi ryo gucukura

Irangi rishobora gushyirwa mu byiciro bitanu bikurikira hakurikijwe uburyo rikoreshwa.

Bidapfutse:

Imbugita zidapfundikiye ni zo zihendutse kandi zikoreshwa mu gukora ibikoresho byoroshye nka aluminiyumu n'icyuma cyoroshye.

Igipfundikizo cya okiside y'umukara:

Irangi rya okiside rishobora gutanga amavuta meza kurusha ibikoresho bidapfundikiye, kandi rinarushaho kuba ryiza mu bijyanye no kugabanya ubushyuhe no kwirinda umuyaga, kandi rishobora kongera igihe cyo gukora ku kigero kirenga 50%.

Igipfukisho cya titanium nitride:

Titanium nitride ni yo ikoreshwa cyane mu gusiga kandi ntikwiriye gukoreshwa mu gutunganya ibikoresho bifite ubukana bwinshi n'ubushyuhe bwinshi.

Igipfukisho cya titanium carbonitride:

Karubonitiride ya Titanium ikomoka kuri nitride ya titanium kandi ifite ubushyuhe bwinshi n'ubudasaza, akenshi ibara ry'umuhengeri cyangwa iry'ubururu. Ikoreshwa mu gukora ibikoresho by'icyuma mu imashini ya Haas.

Igipfundikizo cya Titanium cya Aluminium Nitride:

Nitride ya titanium ya aluminiyumu irwanya ubushyuhe bwinshi kurusha irangi ryose ryavuzwe haruguru, bityo ishobora gukoreshwa ahantu hacukurwa cyane. Urugero, gutunganya superalloys. Irakwiriye kandi gutunganya ibyuma n'ibyuma bitarangirika, ariko bitewe n'ibintu birimo aluminium, habaho ingaruka za shimi mu gutunganya aluminium, bityo irinde gutunganya ibikoresho birimo aluminium.

Imiterere y'ibice by'imashini

Ibiranga imiterere y'ijiometri bishobora kugabanywamo ibice bitatu bikurikira:

Uburebure

Igipimo cy'uburebure n'umurambararo cyitwa double diameter, kandi uko double diameter iba nto, niko double dimeter iba nziza kurushaho. Guhitamo drill ifite uburebure bw'inkombe kugira ngo ikureho chips gusa n'uburebure bugufi bwo kunyonga bishobora kunoza hardness mu gihe cyo gukora drill, bityo bikongera igihe cyo kuyikoresha. Uburebure buke bw'icyuma bushobora kwangiza drill.

Inguni y'isonga ry'umutobe

Inguni yo gucukura ya 118° ishobora kuba ikunze gukoreshwa cyane mu gukora imashini kandi ikunze gukoreshwa ku byuma byoroshye nk'icyuma cyoroshye na aluminiyumu. Imiterere y'iyi nguni akenshi ntabwo ari ukwiyinjiza hagati, bivuze ko ari ngombwa kubanza gucukura umwobo wo hagati. Inguni yo gucukura ya 135° ubusanzwe igira imikorere yo kwiyinjiza hagati. Kubera ko nta mpamvu yo gucukura umwobo wo hagati, ibi bizatuma bidakenewe gucukura umwobo wo hagati ukwawo, bityo bikagabanya igihe kinini.

Inguni ya Helix

Inguni ya helix ya 30° ni amahitamo meza ku bikoresho byinshi. Ariko ku bidukikije bisaba ko habaho uburyo bwiza bwo gukuraho ibyuma binini n'inkombe ikomeye, hashobora gutoranywa icyuma gito gifite inguni ntoya ya helix. Ku bikoresho bigoye gukoresha nk'icyuma kidashonga, igishushanyo gifite inguni nini ya helix gishobora gutoranywa kugira ngo cyohereze imbaraga.
