Xadhiga silsiladda waa shey si caadi ah loo isticmaalo qalabka wax soo saarka wax soo saarka warshadaha, in kasta oo ay aad u badan tahay, laakiin waxay door muhiim ah ka ciyaartaa hawlgalka caadiga ah ee nidaamka wax soo saarka oo dhan. Wax soo saarka dhabta ah, guuldaradii silsiladda si silsiladda ayaa inta badan loo muujiyaa inuu yahay qaybta ugu weyn ee silsiladda silsiladda, oo ay ka kooban tahay 3 qaybood: silsilad silsilad ah, silsilad silsilad ah iyo giraan silsilad ah. Sidaa darteed, faa iidooyinka iyo faa'iido darrooyinka qayb kasta oo ka mid ah gudbinta silsiladda Gudbinta silsiladaha waxay door muhiim ah ka ciyaaraan howlgalka caadiga ah ee loo yaqaan 'compoyar'. Marka loo eego tan, warqaddani waxay inta badan diiradda saareysaa falanqaynta sababaha silsilada silsiladda oo fashilmay, si loo yareeyo qiimaha xagajinta silsiladda, yaree qiimaha dayactirka iyo hagaajinta waxtarka wax soo saarka.

1, noocyada fashilka

Noocyada khaldan ee silsiladda silsiladda leh waxay leeyihiin muujinta soosocda: burburka saxanka, silsiladda mashiinka mashiinka mashiinka mashiinka ah ee ka soo baxa, isku xidhka silsiladda giraanta, burburka silsiladda.

2, Falanqaynta Sababta

Inta badan waxyeelada silsiladda saxanka waa xijaabka xad-dhaafka ah iyo foosha xujinta, mararka qaarkood ifafaale dillaaca. Sababaha ugu waaweyn waa:
① saxanka hoose ee mashiinka mashiinka mashiinka saxanka loo yaqaan 'plate plate' si lama filaan ah loo dhigay ama ka badan xagasha foosha ee uu u baahan yahay qaabeynta;
② Wadajirnimada ee saxanka salka hoose ee mashiinka saxanka silsiladda ma fiicna, ama qayb ahaan waa la ciqaabay;
③ Burooyinka waaweyn ee agabyada la gudbiyey waa la tuuray ama lagu hayo hawlgal ahaan, si silsiladdu ay si xoog leh u saareyso si weyn u saameeya saameynta weyn ee si dhakhso leh;
④ Marka masaafada u dhaxaysa taarikada silsiladaha deriska ah ay ka badan tahay shuruudaha xasaasiga ah, saxanka silsiladda ayaa waxyeello u geysan doonta howlgalka xad-dhaafka muddada-dheer.
