1. Waa in fiiro gaar ah loo yeesho rakibaadda walxaha rinji ee khadka wax soo saarka.Qorshayso xargaha iyo habka loo dhejiyo shayga wax-soo-saarka daahan iyada oo loo marayo tijaabinta hore si loo hubiyo in workpiece uu ku jiro booska ugu fiican inta lagu jiro habka wax-soo-saarka.Diyaarada ugu wayn ee shayga lagu dahaadhayso waa in uu ahaadaa mid toosan,diyaaradaha kalena waa in ay soo bandhigaan xagal 10° ilaa 40° ah oo jiifa, si rinjiga soo hadhay uu si habsami ah ugu soo baxo dusha rinjiga ah.

2. Marka rinjiyeynta, si looga hortago in dareeruhu ku faafo goobta shaqada loogana ilaaliyo in boodhka lagu qaso haanta rinjiga waa in la ilaaliyaa.

3. Ka dib marka walxaha waaweyn la geliyo oo la daboolo, waa inay sugaan dareeraha si buuxda u uumi baxay ka hor inta aan loo dirin qolka qalajinta.

4. Habka rinjiyeynta, fiiro gaar ah u yeelashada rinjiga rinjiga.Viscosity waa in la tijaabiyaa 1-2 jeer halkii shaqo.Haddii viscosity-ku kordho 10%, waxaa lagama maarmaan ah in lagu daro dareeraha wakhtiga.Marka lagu daro dareeraha, hawlgalka dahaadhka dhuuban waa in la joojiyaa.Ka dib marka si isku mid ah loo qaso, hubi viscosity marka hore, ka dibna sii wad qaliinka.

5. Dhumucda filimka rinjiga ayaa go'aamiya xawaaraha horumarinta shayga ee khadka wax soo saarka daahan iyo viscosity ee xalka rinjiga.Ka dib markii la xakameeyo viscosity ee xalka rinjiga, xariiqda wax soo saarka daahan waa in la go'aamiyaa xawaaraha ku habboon ee hore ee xawaaraha ugu badan ee filimka rinjiga ah ee ku saabsan 30um, iyo marka loo eego qalab kala duwan, tijaabooyin.Heerkan, shayga lagu dahaadhay ayaa si siman u horumaray.Heerka horu-marintu waa dhakhso, filimka rinjiguna waa khafiif;heerka horudhacu waa mid gaabis ah, filimka rinjiguna waa dhumuc weyn oo aan sinnayn.

6. Inta lagu jiro hawlgalka daahan dhuuban, mararka qaarkood waxaa laga yaabaa in kala duwanaansho ee dhumucda filimka rinjiga la dahaarka ah iyo qaybta hoose, gaar ahaan ururinta qaro on cidhifka hoose ee shayga dahaarka ah.Si loo hagaajiyo qurxinta dahaarka, marka la isku dhejiyo qaybo yaryar, farsamooyinka buraashka ayaa loo baahan yahay in la isticmaalo si looga saaro dhibcaha rinjiga haray, ama xoogga centrifugal ama qalabka soo jiidashada korantada ayaa loo isticmaali karaa in laga saaro dhibcaha rinjiga.

7. Markaad dhexdaadinayso qaybaha alwaaxyada, fiiro gaar ah u yeelo wakhtiga aan aad u dheerayn si aad uga fogaato dhuuqida alwaaxa rinji aad u badan, taasoo keentay qallajin tartiib ah iyo qashinka.

8. Kobcinta qalabka hawo-siinta si looga fogaado waxyeelada uumiga dareeraha ah;fiiro gaar ah u yeelo habaynta tallaabooyinka ka hortagga dabka oo si joogto ah u hubi khadka wax soo saarka daahan.
