Zida zachitsulo pamene mphamvu yakunja ikupitirira malire a zokolola zake, idzatulutsa mapindikidwe apulasitiki okhazikika, omwe ndi mfundo yaikulu yakupindika kwa chubu.Kupinda chubu, khoma lakunja chifukwa cha kutambasula ndi kupatulira kwake kwapakatikati chifukwa cha kukhuthala, chifukwa cha kutambasula ndi kuponderezana, ndi njira yopindika, gawo lozungulira la chubu lasintha, kusintha kozungulira kukhala kozungulira. njira ya ellipse.

Njira yopindika ya chubu imagawidwa m'mitundu iwiri ya kuzizira ndikupindika, kuzizira kumakhala kutentha ndi makina opindika pachigongono, kupindika kuyamwa gawo lopindika la chubu kumatenthedwa mpaka kutentha kwina, ndiyeno makina (makina opindika chitoliro) kapena pamanja chigongono.Chitsulo chozizira sichimawononga chikhalidwe choyambirira, sichimatulutsa kutentha kwa kutentha.Koma zigongono zozizira zimafunika kugwiritsa ntchito mphamvu zochulukirapo, ndipo kupsinjika komwe kumabwereranso ndikutsalira kumakhala ndi chiwonjezeko chachikulu, koma osati kupindika kopindika kwa mitu yaying'ono yakuthwa yakuzizira.Kupinda sikungayerekezedwe ndi kusinthasintha kozizira.

Kupinda ndi kuwotcherera molingana ndi dongosolo, njira yopindika imathanso kugawidwa kukhala "kupindika koyamba ndi kuwotcherera" ndi "pambuyo pa kupindika koyamba" munjira ziwiri zosiyana zopindika.Otchedwa "woyamba kupinda ndi kuwotcherera," zachokera magawo osiyanasiyana a chubu chitoliro kapena ndodo ngati mbali processing chithunzi anapereka, woyamba chubu kupinda.Ndiyeno mu SAMS kapena SAMS nsanja poika chubu flange kugwirizana Chalk, ntchito kuwotcherera.Kudziwa kutalika kwa molunjika chitoliro kudula Machining mbali monga kujambula kapena chitsanzo chubu ndodo, cholakwa poganizira chigongono, kudula kutalika kwa ndondomeko kuika malipiro ambiri.The "woyamba weld bend" zachokera kutalika kwa chubu kujambula mzere chitoliro kukula kompyuta linanena bungwe mtengo wa mbali chithunzi, wachibale ngodya flange wononga K, flange wononga ngodya ndi pulogalamu NC ndi mndandanda wa deta processing, ntchito palibe. malire pansi zinthu, choyamba pa nsanja kapena SAMS makina pabwino molunjika chitoliro flanges, kuwotcherera, ndiyeno kupinda ntchito.
