Kugura imyitozo ngororamubiri bigufasha kuzigama amafaranga kandi—kubera ko ihora iza mu gasanduku runaka—bigufasha kubika no kumenya neza ibintu. Ariko, itandukaniro risa n'aho rito mu miterere n'ibikoresho rishobora kugira ingaruka zikomeye ku giciro no ku mikorere.
Twashyizeho ubuyobozi bworoshye bwo guhitamo seti y'ibice byo gucukura hamwe n'inama zimwe na zimwe. Ihitamo ryacu rikomeye, Seti y'ibice 29 bya IRWIN's Cobalt Steel Drill Bit, ishobora gukora akazi kose ko gucukura - cyane cyane ibyuma bikomeye, aho ibice bisanzwe byo gucukura byananirana.
Akazi k'imashini yo gucukura ni akoroshye, kandi nubwo imiterere y'ibanze y'umuyoboro itahindutse mu myaka amagana, imiterere y'umutwe wayo ishobora gutandukana kugira ngo igire ingaruka nziza mu bikoresho bitandukanye.
Ubwoko bukunze kugaragara cyane ni imashini zitobora cyangwa imashini zitobora, zikaba ari amahitamo meza yo gukora ahantu hose. Itandukaniro rito ni imashini itobora, yagenewe gukoreshwa n'ibiti kandi ifite umutwe muto kandi utyaye ubuza imashini kugenda (izwi kandi nko kugenda). Uduce tw'amabuye y'agaciro dukurikiza igishushanyo mbonera nk'imashini zitobora, ariko dufite umutwe mugari kandi ugororotse kugira ngo uhangane n'imbaraga zikomeye zikoreshwa.
Iyo imaze kurenza santimetero imwe y'umurambararo, imashini zihindura isura ziba zidakora. Imashini ubwayo yarushijeho kuba nini kandi ikomeye. Intambwe ikurikiraho ni imashini ihindura isura, iba iringaniye ifite imisumari ku mpande zombi n'agace k'icyuma hagati. Imashini zihindura isura n'uduti duto (Forstner) nazo zirakoreshwa (zitanga imyobo isukuye kurusha uduti duto, ariko zihenda cyane), utundi duto twitwa utumashini duto. Aho gucukura umwobo mu buryo busanzwe, izi mashini zica uruziga rw'ibikoresho. Inini ishobora gukata imyobo ya santimetero nyinshi z'umurambararo mu duti twa sima cyangwa ibiti bya cinder.
Uduce twinshi two gucukura dukozwe mu cyuma cyihuta cyane (HSS). Ntiduhenze, tworoshye gukora impande ziciritse, kandi turaramba cyane. Dushobora kunozwa mu buryo bubiri: guhindura imiterere y'icyuma cyangwa kugisiga ibindi bikoresho. Ibyuma bya Cobalt na chrome vanadium ni ingero z'ibya mbere. Bishobora gukomera cyane kandi bikarinda kwangirika, ariko birahenze cyane.
Irangi rihendutse kuko ari utwenda duto ku mubiri wa HSS. Tungsten carbide na oxide y'umukara birakunzwe cyane, kimwe na titanium na nitride ya titanium. Uduce two gucukura dupfundikiye twa diyama two gucukuramo ikirahure, keramike n'uduce tunini tw'amabuye y'agaciro.
Itsinda ry'ibikoresho by'ibanze bya HSS bingana na cumi na bibiri bigomba kuba bisanzwe mu bikoresho byo mu rugo. Niba wabivunnye, cyangwa niba ufite ibyo ukeneye byihariye birenze ubushobozi bwabyo, ushobora kugura ikindi gisimbura. Itsinda rito ry'ibikoresho by'amabuye ni ikindi kintu gisanzwe cyo gukora.
Uretse ibyo, ni umugani wa kera uvuga ko ufite ibikoresho bikwiye by'akazi. Kugerageza gukora imyitozo ngororamubiri idakwiye kugira ngo ukore akazi birababaza kandi bishobora kwangiza ibyo ukora. Ntabwo bihenze, bityo buri gihe birakwiye gushora imari mu bwoko bukwiye.
Ushobora kugura imashini zitobora zihendutse ku mafaranga make, rimwe na rimwe ukabyikorera ubwawe, nubwo akenshi zihita zigabanuka. Ntitwakugira inama yo gukoresha uduce duto tw’amabuye y’agaciro gake—akenshi, ntacyo bimaze. Hari ubwoko butandukanye bw’uduce duto tw’amabuye y’agaciro rusange tuboneka ku madolari 15 kugeza 35, harimo n’uduce duto twa SDS. Igiciro cya cobalt kiri hejuru, kandi uduce duto dushobora kugera ku madolari 100.
A. Ku bantu benshi, birashoboka ko atari byo. Ubusanzwe, biba bifite ubushyuhe bwa dogere 118, ibyo bikaba ari byiza cyane ku mbaho, ibikoresho byinshi bivanze, n'ibyuma byoroshye nka umuringa cyangwa aluminiyumu. Niba urimo gucukura ibikoresho bikomeye cyane nk'icyuma gishongeshejwe cyangwa icyuma kidashonga, inguni ya dogere 135 ni nziza.
A. Biragoye gukoresha n'intoki, ariko hari ubwoko butandukanye bw'ibikoresho byo gusya cyangwa ibikoresho bitandukanye byo gusya. Ibikoresho byo gusya karubide n'ibikoresho byo gusya titanium nitride (TiN) bisaba icyuma cyo gusya gishingiye kuri diyama.
Icyo dukunda: Amahitamo menshi y'ingano zisanzwe muri kaseti yoroshye gukurura. Kobalt irinda ubushyuhe no kwangirika kugira ngo ikoreshwe igihe kirekire. Inguni ya dogere 135 itanga uburyo bwo gukata icyuma neza. Inkweto za rubber zirinda agasanduku.
Icyo dukunda: Agaciro gakomeye, igihe cyose usobanukiwe n'imbogamizi z'ibice bya HSS. Itanga imyitozo n'ibinyabiziga ku mirimo myinshi yo mu rugo, muri gareji no mu busitani.
Icyo dukunda: Hari uduce dutanu gusa two gucukura, ariko dufite ingano y'imyobo 50. Gupfuka titanium kugira ngo birambe. Igishushanyo cyihariye, gifite ubuziranenge bwo hejuru. Uduce duto ku gice cy'inyuma dufasha gucukura gucika.
