Maanta, waxaan ku siin doonaa sharaxaad kooban oo ku saabsan qaabka iyo isticmaalka muraayadda muraayadda mashiinka nadiifinta, anigoo rajeynaya inaan caawiyo isticmaalayaasha isticmaala mashiinka nadiifinta.
Guud ahaan, shaashadda gariirta mashiinka nadiifinta (sidoo kale loo yaqaan mashiinka baarista, kala-soocida aasaasiga ah) waxay isticmaashaa xaashi galvanized feeray.Marka loo eego ujeedada qalabka wax lagu farsameeyo, waxaa jira 2-6 lakab oo qaab dhismeed ah, kaas oo loo isticmaali karo in laga saaro wasakhda waaweyn iyo wasakhda yaryar oo loo kala saaro iyada oo loo eegayo xajmiga dibadda ee miraha ama hadhuudhka.
Shaashada feerka ee sida caadiga ah loo isticmaalo waxaa ka mid ah godadka wareegsan iyo godadka dhaadheer.Si loo hubiyo ka faa'iidaysiga wax ku oolka ah ee goobta shaashadda, waxaa jira qabanqaabooyin kala duwan.Daloollada badan ee isla shaashada, ayaa sare u kaca xajinta iyo isticmaalka, laakiin ma aha mid dhamaystiran.Cufnaanta godadka feerka waxay sidoo kale ku xiran tahay dhumucda iyo xoogga shaashadda.
Shaashadda wareegga wareegga, taas oo inta badan xaddidaysa ballaca dalagyada;Shaashadda daloolka dheer ayaa inta badan xaddidaysa dhumucda dalagga.Fadlan eeg cabbirrada saddex-geesoodka ah ee dalagyada hoose si ay kaaga caawiyaan inaad fahamto dhererka, ballaca iyo dhumucda dalagga.
Qaar ka mid ah dalagyada (sida miraha gabbaldayaha, bariiska, iwm.) ayaa laga yaabaa inay u baahdaan in la baaro iyadoo loo eegayo dhererkooda, laakiin nadiifiyaha godka ayaa loo isticmaalaa, taas oo ah nooc kale oo qalab ah, markaa anigu halkan faahfaahin kama geli doono.Warqadani waxay inta badan ka hadlaysaa sida kuwa nadiifka ah u nadiifiyaan dalagga iyadoo loo eegayo ballaca iyo dhumucdooda.
Qaadashada baarista abuur sarreen ah tusaale ahaan, guud ahaan marka la hadlo, shaashad gariir leh qaab dhismeed saddex lakab ah ayaa la qaatay, oo leh dalool wareegsan oo ah 5.6mm lakabka koowaad, dalool dheer oo 3.8mm ah lakabka labaad iyo dalool dheer of 2.0-2.4mm ee lakabka saddexaad.(Qiimaha kor ku xusan, daloolka wareegsan wuxuu tilmaamayaa dhexroorka, godka dheerna wuxuu tilmaamayaa ballaca godka shaandhada).Waraaqaha shaandhada koowaad iyo labaad waxaa loo isticmaalaa in laga saaro wasakhda waaweyn ee sarreenka, isla mar ahaantaana, waxaa lagama maarmaan ah in la hubiyo in sarreenku uu si habsami leh ugu dhici karo xaashida shaandhada saddexaad.Doorka lakabka saddexaad ee shaandhada ayaa ah in la hubiyo in sarreenku aanu sii dhici karin, iyo qaar ka mid ah wasakhda yaryar waxay sii wadi karaan inay si habsami leh u dhacaan.
Dheefta shaandhada godka dheer waxay ka sarraysaa tan shaandhada daloolka wareegta ah, sida samaynta digirta, taas oo sidoo kale ah 11.0mm dalool dheer iyo qaybo shaandho wareeg ah.Maaddooyinka ka soo daatay shaandho dalool dheer ayaa iska cad inay ka badan yihiin jeexjeexyada shaandhada godka wareegsan, iyo ulaha qaarkood ayaa inta badan ku soo dhici kara qaybo shaandho dheer, halka laga saari karo shaandho wareegsan oo dalool ah.Sidaa darteed, alaabooyinka intooda badan, waxaan caadi ahaan dooraneynaa inaan isticmaalno shaashadda godka dheer ee shaashadda hoose, taas oo u oggolaan karta qaar ka mid ah ulaha yaryar inay hoos u dhacaan, halka muraayadda sare ay inta badan doorato godadka wareegsan si looga hortago ulaha waaweyn inay ku dhacaan shaashadda soo socota ee miraha ama hadhuudh.
Saxnaanta daloolka shaandhada waa mid aad muhiim u ah, taas oo si toos ah u go'aamisa nadiifinta baarista abuurka iyo isku mid ahaanshaha darajada, iyo saxnimadeeda inta badan waxay gaartaa heerka 0.1 mm.Qaar ka mid ah dalagyada lacagta caddaanka ah ama miraha yaryar, waxay u baahan yihiin inay noqdaan kuwo sax ah ilaa heerka 0.01 mm.
