Ciidda-qarxinta waa shaqo u adeegsata hawo isku-duuban oo ah awood si ay ugu riixdo nabarrada dusha sare ee qalabka shaqada si loogu habeeyo. Kani waa waxa loo yaqaan ciid-qarxinta, taas oo ah waxa aynu inta badan ugu yeedhno qarxinta rasaasta. Maxaa yeelay, waagii hore ee rasaastu qaraxday, ciiddu waxay ahayd nabarrada keliya ee la isticmaali karo, sidaas awgeed qarxinta xabbaddu waxa loo yaqaannaa ciidda qarxinta wakhtigaas iyo muddo dheer ka dib. Bacaad-qarxinta waxay ka dhigi kartaa in dusha la nadiifiyo la helo nadaafadda loo baahan yahay iyo qallafsanaanta qaarkood, waxayna wanaajisaa ku-dhejinta dahaarka ee dusha sare. Si kasta oo dahaarka u fiican yahay, laguma dhejin karo dusha sare ee shaqada iyada oo aan la helin daaweyn dusha sare ah oo dheer. Ujeedada daaweynta dusha sare waa in la nadiifiyo dusha sare oo soo saaro qallafsanaanta loo baahan yahay si loo "quful" dahaarka dusha sare. Ka dib markii dusha sare ee workpiece sandblasted lagu dahaadhay daahan warshad-waxqabadka wanaagsan, nolosha adeegga ee daahan waa 3.5 jeer ka dheer nolosha adeegga ee daahan tayada la mid ah dusha lagu daweeyey by habab kale. Faa'iidada kale ee ciid-qarxinta (qarax rasaas ah) waa in qallafsanaanta dusha sare loo sii go'aamin karo iyadoo loo eegayo shuruudaha waxaana lagu gaari karaa inta lagu jiro habka nadiifinta.
Qaboobintu waa, tusaale ahaan, hannaan uu adhalada dhalada la isku qurxiyonoqda mid siman oo noqda matte. Iftiinku wuxuu iftiimiyaa dusha sare si uu u sameeyo milicsi fidsan. Dhaxan kiimikaad, muraayadda si farsamaysan ayaa loo fuliyaa ama gacanta lagu fuliyaa iyadoo leh emery, ciid silica, budada rummaanka iyo abrasives kale si ay u sameeyaan dusha sare oo qallafsan, ama galaaska iyo walxaha kale waxaa lagu daweyn karaa xal hydrofluoric acid si loo sameeyo galaas barafaysan.
Dhaxan iyo ciid-qarxinta labaduba waxa loo isticmaalaa in lagu daboolo oogada muraayadda, si uu iftiinku si siman u faafo ka dib marka uu dhex maro nalka. Way ku adag tahay isticmaalayaasha caadiga ah inay kala saaraan labadan tignoolajiyada. Kuwa soo socdaa waxay sharxayaan hababka wax-soo-saarka ee labadan tignoolajiyada iyo sida loo aqoonsado.
1. Habka dhaxan
Qaboojinta waxaa loola jeedaa in galaaska lagu dhex geliyo dareere aysiidh ah oo diyaarsan (ama codsanaya koollada aashitada ah), daxallinta dusha dhalada oo leh asiidh xooggan, iyo hydrogen fluoride ammonia ee ku jirta xalalka aashitada xooggan waxay keentaa in dusha sare ee muraayadda ay sameeyaan crystals. Sidaa darteed, haddii habka barafku si fiican loo sameeyo, dusha sare ee muraayadda barafku waa mid aad u siman, iyo kiristaalo firidhsan ayaa soo saara saameyn xun. Haddii dusha sare uu aad u qallafsan yahay, tani waxay muujinaysaa in aysiidhku si ba'an u baabi'inayso muraayadda, ama qaar iyaga ka mid ah ayaa weli haysan wax crystals. Tilmaamaha habkani waa muuqaalka muraayadaha dhalaalaya ee dusha muraayadda ee lagu sameeyay xaalado halis ah. Sababta ugu weyn ayaa ah in hydrogen fluoride ammonia ay ku dhowdahay in la isticmaalo. Si loo gaaro gobolkan, warshado badan ayaa sameeyay isku dayo iyo daraasado badan, laakiin ma aysan awoodin inay ka gudbaan dhibaatadan.
2. Farsamada ciid-qarxinta
Waxay isticmaashaa qaybaha ciidda ee uu soo saaray qoriga buufinta xawaare sare leh si ay ugu dhufato dusha muraayadda si ay u sameeyaan dusha sare ee aan sinnayn, si ay u gaadho saamaynta iftiinka kala firdhiya, iyo samaynta dareemo huur ah marka iftiinku dhex maro. Dusha sare ee alaabta dhalada ah ee ay soo saarto habka ciiddu waa mid qallafsan. Sababtoo ah dusha sare ee muraayadda ayaa waxyeello gaartay, waxay u egtahay muraayad cad marka loo eego sawir-qaadista muraayadda hufan ee asalka ah.
Labada hab gebi ahaanba way kala duwan yihiin. Muraayadaha barafaysan ayaa ka qaalisan galaaska ciidaysan, saamayntuna waxay inta badan ku xidhan tahay baahida isticmaaleyaasha. Qaar ka mid ah muraayadaha gaarka ah kuma habboona dhaxan. Marka la eego raadinta sharafta leh, matte waa in la doortaa. Geedi socodka ciidda qarxinta waxaa lagu samayn karaa warshado guud, laakiin habka ciiddu ma fududa in si fiican loo sameeyo.
