Imyitozo ya drill igabanijwemo amabara?Ni irihe tandukaniro riri hagati yabo?Nigute ushobora guhitamo?

Gucukura nuburyo busanzwe bwo gutunganya mubikorwa.Mugihe ugura bits, imyitozo ya drill iza mubikoresho bitandukanye n'amabara atandukanye.Nigute amabara atandukanye ya drill bits afasha?Ibara hari aho rihuriye nubwiza bwa drill?Ni ubuhe bwoko bwa drill bit nziza kuruta kugura?

Mbere ya byose, dukeneye kumvikanisha neza ko ubwiza bwimyitozo idashobora gucibwa gusa nibara ryayo.Nta sano itaziguye kandi byanze bikunze hagati yamabara nubuziranenge.Amabara atandukanye ya drits bits biterwa ahanini nubuhanga butandukanye bwo gutunganya.Byumvikane ko, dushobora gufata icyemezo gikaze dushingiye kumabara, ariko uyumunsi ubuziranenge bwimyitozo ngororamubiri nayo izatunganya amabara yabo kugirango tugere kumyitozo yo murwego rwohejuru.

None ni irihe tandukaniro riri hagati yimyitozo yamabara atandukanye?

Ubuziranenge bwo hejuru bwuzuye bwihuta bwibyuma bitsindagira akenshi biboneka mweru.Byumvikane ko imyitozo ya rot ya bito irashobora kandi kwera mugusya neza uruziga rwo hanze.Igituma bakora ubuziranenge ntabwo aribikoresho ubwabyo, ahubwo ni no kugenzura ubuziranenge mugihe cyo gusya.Birakomeye rwose kandi ntihazongera gutwikwa hejuru yigikoresho.Ibirabura ni Nitride drill bits.Nuburyo bwa chimique bushyira igikoresho cyarangiye muruvange rwa ammonia hamwe numwuka wamazi kandi bigakora uburyo bwo kubungabunga ubushyuhe kuri 540 ~ 560C ° kugirango bongere igihe cyigikoresho.Ibyinshi mu bikoresho byirabura byirabura kurubu ku isoko ni umukara gusa (kugirango uhishe ibicanwa cyangwa uruhu rwirabura hejuru yigikoresho), ariko ingaruka zikoreshwa ntizigeze zikorwa neza.

Hariho inzira 3 zo kubyara bits.Kuzunguruka umukara ni bibi cyane.Abazungu bafite impande zisobanutse kandi zisukuye.Kubera ko okiside yubushyuhe bwo hejuru idasabwa, imiterere yintete yicyuma ntizasenywa, irashobora gukoreshwa mugucukura ibihangano hamwe nuburemere buke buke.Imyitozo yumuhondo-umukara irimo cobalt, ni itegeko ritavuzwe mu nganda za biti.Diyama irimo Cobalt yabanje kwera, ariko nyuma ihinduka atom yumuhondo-umukara (bakunze kwita amber).Nibimwe mubyiza kurubu bizenguruka.M35 (Co 5%) ifite kandi ibara rya zahabu ryitwa titanium isize drill bit, igabanijwemo imitako ishushanya hamwe ninganda.Isahani yo gushushanya ntabwo ari nziza, irasa neza.Ingaruka zo gukwirakwiza amashanyarazi ni nziza cyane.Ubukomezi bushobora kugera kuri HRC78, burenze ubukana bwimyitozo ya cobalt (HRC54 °).

Nigute ushobora guhitamo bito

Ko ibara ritari igipimo cyo gusuzuma ubuziranenge bwa bito, nigute wahitamo bito?

Uhereye kubunararibonye, ​​mubisanzwe, ibice byera byera mubisanzwe byuzuye hasi byihuta byuma byuma kandi bigomba kugira ubuziranenge bwiza.Izahabu zifite nitride ya titanium kandi mubisanzwe nibyiza cyangwa bibi kandi birashobora gushuka abantu.Ubwiza bwirabura nabwo buratandukanye.Bamwe bakoresha ibyuma byujuje ubuziranenge ibyuma bya karubone, byoroshye guhuza no kubora, bityo bigomba gukara.

Hano haribimenyetso byerekana kwihanganira diameter kuri shank ya biti ya myitozo, mubisanzwe birasobanutse, kandi ubwiza bwa laser na electro-etching ntibukwiye kuba bubi cyane.Niba inyuguti zibumbabumbwe zifite impande zombi, byerekana ko imyitozo ya biti itujuje ubuziranenge, kubera ko umurongo wa convex yerekana inyuguti bizatera umwitozo bitobito neza kunanirwa kubahiriza ibisabwa.Impera yijambo ihujwe neza na silindrike yubuso bwakazi, kandi imyitozo ya bito hamwe nuruhande rusobanutse rwijambo ni ryiza.Ugomba gushakisha umwitozo bito hamwe no gukata neza kuruhande.Imyitozo yuzuye yubutaka ifite impande nziza zo gukata kandi zujuje ibisabwa hejuru ya helix, mugihe imyitozo idahwitse ifite isura mbi.
