Imiterere yibice bya superabrasive hamwe nibigize igifuniko bigira uruhare runini muburyo bwo gusya ibiziga kubikorwa bitandukanye.
Guhuza porogaramu ninziza nziza ya superabrasive irashobora kunguka mugutezimbere ubuziranenge bwumusaruro nigicuruzwa, gukora ubumenyi bwimbitse bwa grit, bond hamwe nuburinganire bukomeye kubakoresha urusyo.Ifoto tuyikesha Wanyu Abrasives.
Guhitamo neza kwiziga rikomeye cyane ni ngombwa muburyo bwo gusya neza.Uruziga rwiburyo rushobora guhindura ibice mu isaha, kugabanya ibikoresho, kongera imashini igihe, kuzamura ubwiza bwibicuruzwa no kugabanya ibiciro byo gukora.Ariko, kubona uruziga bisaba kwiga witonze imiterere yintete no gutwikira superabrasive, mubindi biranga.
Ibiziga bya supererabrasive bikora muburyo bwo gusya cyane kandi bigomba kuba bifite ibintu byinshi, harimo ubukana bwubushyuhe bwo hejuru, ubushyuhe bwinshi bwumuriro kugirango ukure ubushyuhe kumupaka, guhagarara neza, kwambara, kurwanya amavuta no kurwanya ihindagurika rya plastike.
Imikorere y'uruziga ruhebuje rushyirwaho mbere na mbere na substrate ihujwe, kimwe n'ibiranga ubuziranenge hamwe n'ubwiza bw'ingano zangiza ibiziga, yaba diyama cyangwa nitride ya cubic boron (CBN).Ibice bitandukanye hamwe nibitambaro bitanga imbaraga zitandukanye kandi birakwiriye kubikorwa bitandukanye.Kumenya ibice hamwe nibitambaro nibyiza mubikorwa byihariye birashobora kuzigama ababikora amafaranga mugihe.
Ukurikije gusaba cyangwa gusya, ingano nziza cyangwa ingano zihenze birashobora kuba amahitamo yubukungu cyane kumurimo.Mu buryo nk'ubwo, ibiziga bihenze cyane bya diyama cyangwa CBN ntibishobora kuba bibereye porogaramu runaka.Icyangombwa ntabwo ari igiciro, ahubwo ni imiterere yintete za superabrasive nubwoko bwimyenda ikoreshwa kumuziga.
Gukomera bivuga imyitwarire yintete zangiza ziterwa nubukanishi, ni ukuvuga ubushobozi bwayo bwo kurwanya gucika, gutemagura, no kumeneka.Ubupfura bivuga ubushobozi bwimbuto zo kumeneka no kwikarisha.
Ibinyampeke bikabije super abrasive bikunda kuba binini kandi bifata imiterere yabyo kuruta gukuramo ibikoresho.Uduce duto duto duto duto cyane, imiterere yimfuruka ikuraho ibintu byinshi hamwe na buri pass.Porogaramu zitandukanye zisaba ibinyampeke ahantu hatandukanye kumurongo uri hagati yuburyo bubiri.
Kubireba imiterere, hari ibyiciro bibiri bya polar: guhagarika no kuruhande.Kurenza uko byegeranye cyangwa bizengurutse ibice byangiza, ntigukata neza, ariko nuburyo bwiza bugumaho.Ibice byacitse birakomeye kandi birwanya imbaraga zo gukuramo mbere yo kumeneka.
Ibinyuranye, imiterere yinguni irakaze kandi nziza yinjira no gukuraho ibintu.Ariko, ingano zinguni zirasenywa nimbaraga nke.
Byaba byiza, hagomba kubaho agace karinganiza iyi miterere yombi, kayemerera gukomeza gukomera, ikemerera gusenyuka bisanzwe, ikagaragaza impande nshya, ityaye.Hatariho ubushobozi bwo gusenyuka, ibinyampeke bizacika intege kandi bikubite ku gihangano aho gukata, bitera kwiyongera kwingufu zo gusya hamwe nibibazo bikomeye kumuziga no kumurimo.
Gupfundikanya ni inzira yo gutwikisha ibinyampeke bya superabrasive hamwe nigice cyibikoresho byinyongera.Ubu buryo bwongera ingano nuburemere, bukoreshwa kenshi mugutezimbere imico nkimbaraga nigihe kirekire mugusya.
Imbaraga za matrix ihujwe kugirango ifate ingano zangiza zigena imikorere yuruziga.Inyungu nyamukuru yimyenda ni uko ishobora gutunganya ibice bya diyama cyangwa CBN kugirango irusheho kwizirika ku ruziga, yaba resin, vitreous, ibyuma, hybrid cyangwa ibindi.Kunoza imashini na chimique kugumana sisitemu yo guhuza byongera ubunyangamugayo.
Ikiguzi cyo kuzigama hamwe numusaruro mwinshi uzanwa no guhitamo uruziga rukwiye rushobora guhinduka inyungu zipiganwa mugihe amahugurwa akina amakarita yayo neza.
Nickel, umuringa na feza bitwikiriye cyane.Isahani ya Nickel irasanzwe muri resin ihujwe.Iyi myenda itezimbere ubuzima bwibiziga, kurangiza hejuru, gukwirakwiza ubushyuhe hamwe no gufatisha imashini guhuza ibice kugirango ibikorwa byinshi bigerweho.
Umuringa ni umuringa wo guhitamo gusya byumye bitewe nubushobozi bwumuringa bwo gutwara ubushyuhe kure y’urusyo no kunoza imikoreshereze y’imashini n’imiti muri sisitemu ihujwe.
Ifeza ya feza ihenze cyane ariko itanga ubushyuhe bwo hejuru bwubwoko butatu bwo gutwikira, hamwe no kugumana uduce duto hamwe nubundi buryo bwo kwisiga.Ifeza niyo yatoranijwe kurangiza iyo amavuta meza akoreshwa nka coolant.
Ingano yo gutwikira ku ngano yangiza irashobora kuva kuri 30% kugeza kuri 70% yuburemere bwuzuye bwingano.Ipitingi ku bice bya diyama mubisanzwe ni 50% kugeza kuri 56% kuburemere, mugihe uduce twa CBN dukunze gukoreshwa kuri 60% kuburemere.Superabrasives zifunitse zikunda kuba zihenze kuruta imiti idahwitse kubera imikorere yabo iteganijwe hamwe nintambwe yinyongera yinganda zisabwa kugirango zibibyaze umusaruro.
Ndetse na bike byahinduwe kuri abrasive mumashini yo gusya birashobora kuba umukino uhindura sisitemu yo gusya hamwe nibikorwa.Ikiguzi cyo kuzigama no kongera umusaruro muguhitamo uruziga rwiza rushobora guhinduka byoroshye kurushanwa mugihe amahugurwa akina amakarita yayo neza.
Ukoresheje tekinoroji yohejuru, ikora cyane murwego rwo gutunganya, tekinoroji ya SolidCAM iMachining irashobora kugabanya cyane ibihe byizunguruka no kongera ubuzima bwibikoresho ugereranije no gusya gakondo.
Imbaraga zigira uruhare mu gusya zirashobora kubarwa, bigatuma ibikoresho by'imibare byakoreshwa mu guhanura no kugenzura izo mbaraga.Inzira zifatika zo kubara izo mbaraga zigufasha guhindura ireme ryimirimo yo gusya.
