Ibyuma bitagira umwanda biza muburyo busanzwe.Ni ngombwa kumenya icyo ibyo birangiriraho aribyo n'impamvu ari ngombwa. Udushya tugezweho mu ikoranabuhanga ryangiza rishobora kugabanya inzira zogutanga ibyifuzo byifuzwa, harimo nubushakashatsi bwashakishijwe.
Ibyuma bitagira umuyonga birashobora kugorana gukorana, ariko ibicuruzwa byarangiye bitanga kimwe mubyiza kandi bigatuma imirimo yose iba iyihesha agaciro.Biremewe muri rusange ko gukoresha grit nziza muburyo bukurikirana umusenyi bishobora kuvanaho ibishushanyo byashize hanyuma bikanoza kurangiza, ariko hariho intambwe nyinshi muri rusange ugomba kumenya mugihe ukoresheje grit nyinshi zikurikirana kugirango ugere kubyo wifuza.

Inganda zidasanzwe zo muri Amerika y'Amajyaruguru (SSINA) zisobanura ibipimo nganda n'aho ibicuruzwa bikoresha imibare itandukanye.
No 1 birakorwa. Ubu buryo bwo kuvura bukozwe no kuzunguruka (gushyushya) ibyuma bitagira umwanda byashyutswe mbere yo kuzunguruka. Birasabwa kurangiza bike cyane, niyo mpamvu bifatwa nkibikomeye. Ibicuruzwa bisanzwe bifite nimero ya 1 ni ibyuma bishyushya ikirere, udusanduku twa annealing, utubati twinshi, ibice bitandukanye byitanura, hamwe na gaz turbine, twavuga bike.
No 2B iruzuye. Ubu buso bwerurutse, buzengurutse ubukonje bumeze nkindorerwamo yibicu kandi ntibisaba ko habaho intambwe yo kurangiza.Ibice bifite 2B birangiza birimo ibipapuro rusange, ibikoresho byinganda zikora imiti, ibikoresho, uruganda rukora impapuro nibikoresho byo gukoresha amazi.
Na none mu cyiciro cya 2 ni 2D irangiza.Iyi nsozero ni imwe, ya feza ya matte yijimye kumyenda yoroheje, ubunini bwayo bwaragabanutse nuburyo bukonje bwo gukonjesha ntoya kuko akenshi bikoreshwa no kurangiza uruganda. Gutoragura cyangwa kumanura birasabwa nyuma yo kuvura ubushyuhe kugirango ukureho chromium. Iyo gutoranya bishobora kuba intambwe yanyuma yo gutunganya nkuko bisabwa irangi ryiza.
Igipolonye No 3 kirangwa nimirongo migufi, igereranije cyane, iringaniza imirongo ya polishinge.Biboneka mugukonjesha imashini hamwe no gukuramo buhoro buhoro cyangwa kunyuza ibiceri binyuze mumuzingo udasanzwe ukanda ibishushanyo hejuru, bigereranya isura yimyenda yubukorikori.Ni iherezo ryerekana neza.
Kumashanyarazi ya mashini, grit ya 50 cyangwa 80 isanzwe ikoreshwa muburyo bwambere, naho grit 100 cyangwa 120 isanzwe ikoreshwa kuri polish ya nyuma. Ubusugire bwubutaka busanzwe bufite impuzandengo yikigereranyo (Ra) ya microinches 40 cyangwa munsi yayo.Niba uwabikoze akenera gusudira fusion cyangwa ibindi birangira, umurongo wa polishinge uba usanzwe ari muremure kuruta ibyo uruganda rukora ibikoresho, ibikoresho byo mu gikoni, ibikoresho bikoreshwa mubikoresho byo mu gikoni, ibikoresho bikoreshwa mubikoresho byo mu gikoni, ibikoresho bikoreshwa mubikoni.
No 4 kurangiza nibisanzwe kandi bikoreshwa mubikoresho byinganda ninganda zibiribwa.Isura yayo irangwa nimirongo migufi iringaniye isennye irambuye iringaniye hamwe nuburebure bwa coil.Bibonwa no gukanika imashini irangiza No 3 hamwe no gukuramo buhoro buhoro. Ukurikije ibisabwa kubisabwa, kurangiza kwanyuma birashobora kuba ahantu hose hagati ya 120 na 320 grit.
Ubusanzwe Ubuso busanzwe ni Ra 25 µin.kandi munsi.Iyi ndunduro ikoreshwa cyane mubikoresho bya resitora nigikoni, ububiko, ibikoresho byo gutunganya ibiryo ndetse n’ibikoresho by’amata.Nkuko hamwe na Finish No 3, niba uyikoresha akeneye guhuza gusudira cyangwa gukora ibindi bintu byarangiye, umurongo uva mubusanzwe usanga ari muremure kurenza umurongo wibicuruzwa bisizwe nuwabikoze cyangwa ibizunguzungu.
Igipolonye No 3 kirangwa nimirongo migufi, igereranije cyane, iringaniza imirongo ya polishinge.Biboneka mugukonjesha imashini hamwe no gukuramo buhoro buhoro cyangwa kunyuza ibiceri binyuze mumuzingo udasanzwe ukanda ibishushanyo hejuru, bigereranya isura yimyenda yubukorikori.Ni iherezo ryerekana neza.
Kurangiza No 7 biragaragaza cyane kandi bifite isura isa nindorerwamo. Yakozwe kuri 320 grit kandi isize No 7 kurangiza irashobora kuboneka kenshi mumutwe winkingi, imitako ishushanya hamwe nimbaho.
Habayeho iterambere ryibanze muri abrasives zikoreshwa kugirango ibyo bisozo birangire, bifasha ababikora gukora ibice byinshi mumutekano, byihuse kandi bidahenze.Imyunyu ngugu mishya, fibre ikomeye hamwe na sisitemu ya resin antifouling ifasha muburyo bwo kurangiza.
Ibi bivanaho bitanga kugabanuka byihuse, kuramba, no kugabanya umubare wintambwe zikenewe kugirango akazi gakorwe.Urugero, flap hamwe na microcracks mubice bya ceramic byongerera ubuzima ubuzima bwihuse kandi bitanga kurangiza bihoraho.
Byongeye kandi, tekinoroji isa noguteranya abrasives ifite uduce duhuza kugirango tugabanye vuba kandi dutange kurangiza neza.Bisaba intambwe nkeya hamwe nububiko buke bwo gukora akazi, kandi ababikora benshi babona imikorere myiza no kuzigama amafaranga.

Ababikora barasabwa kuzuza inguni na radiyo yibice byicyuma.Kuvanga bigoye gushobora gusudira no gushinga uduce, bifite inzira yintambwe eshanu zisaba uruziga rusya, ipadiri ya kare ya grits nyinshi, hamwe nuruziga rumwe.
Ubwa mbere, abakoresha bakoresha uruziga rwo gusya kugirango bakore ibishushanyo byimbitse kuri ibyo bikoresho byuma bidafite ingese.Ibiziga byo gusya muri rusange birakomeye kandi ntibibabarira, bigashyira umukoresha mubi mu ntangiriro. Intambwe yo gusya yatwaraga igihe kandi iracyasiga ibishushanyo byagombaga gukurwaho nintambwe eshatu ziyongera kurangiza intambwe zingana zingana.
Muguhindura uruziga rwo gusya kuruziga rwa ceramic lobe, uwayikoresheje yashoboye kurangiza gusya mu ntambwe yambere. Komeza urukurikirane rwa grit nkurwego rwa kabiri, uwasimbuye yasimbuye amakarito ya kare akoresheje uruziga rwa flap, atezimbere igihe arangiza.
Kuraho 80-grit kare ya padi no kuyisimbuza mandel idakozwe hamwe nuduce duto twa agglomerated ikurikirwa na 220-grit idafite ubudodo bwa mandel ituma uyikoresha akora sheen yifuza kandi arangije muri rusange kandi bikuraho ibikenewe intambwe yanyuma niyo nzira yambere (koresha uruziga rw'ubumwe kugirango ufunge intambwe).
Bitewe no kunoza ibiziga bya flapper hamwe nikoranabuhanga rudoda, umubare wintambwe wagabanutse uva kuri batanu ujya kuri bane, bigabanya igihe cyo kurangiza ku kigero cya 40%, bizigama imirimo nigiciro cyibicuruzwa.
Habayeho iterambere ryibanze muri abrasives zikoreshwa kugirango ibyo bisozo birangire, bifasha ababikora gukora ibice byinshi mumutekano, byihuse kandi bihendutse.
WELDER, yahoze ari Welding Pratique uyumunsi, yerekana abantu nyabo bakora ibicuruzwa dukoresha kandi dukorana burimunsi.Iki kinyamakuru kimaze imyaka isaga 20 gikorera umuryango wo gusudira muri Amerika ya ruguru.
