S\u0131radan mandrel:<\/p>\n
CNC boru b\u00fckme makinesi 6 veya 8 mm \u00e7ap\u0131nda bir boruyu b\u00fckt\u00fc\u011f\u00fcnde, k\u00fc\u00e7\u00fck \u00e7ap ve mandrelin nispeten b\u00fcy\u00fck destek kuvveti nedeniyle, mandrel ihmal edilebilir ve b\u00fckme par\u00e7as\u0131n\u0131n ovalli\u011finin \u00e7ap\u0131n 5% i\u00e7inde olmas\u0131 garanti edilir.

Boru ileri do\u011fru \u00e7ekildi\u011finde, mandrelin hareketi nedeniyle, borunun merkez hatt\u0131n\u0131n d\u0131\u015f\u0131ndaki malzeme te\u011fet noktada desteklenecek, gerilecek ve \u015feklini ve s\u00f6nmemesini sa\u011flamak i\u00e7in sertle\u015ftirilecektir.<\/p>\n
Mandrelin konumu b\u00fckme noktas\u0131nda olmal\u0131d\u0131r ve te\u011fet noktas\u0131n\u0131n konumu borunun ovalli\u011fini ve borunun geri tepmesini etkiler.<\/p>\n
Mandrel \u00e7ok ilerideyse, t\u00fcp\u00fcn merkez \u00e7izgisinin d\u0131\u015f\u0131ndaki malzeme kolayca gerilir ve incelir, uzunluk artar ve geri tepme k\u00fc\u00e7\u00fcl\u00fcr ve ovalite de k\u00fc\u00e7\u00fck olur, ancak bir kaz ba\u015f\u0131 fenomeni vard\u0131r; bazen dalgalanmalar e\u015flik eder.<\/p>\n
Mandrel \u00e7ok gerideyse, t\u00fcp\u00fcn merkez \u00e7izgisinin d\u0131\u015f\u0131ndaki malzeme yeterince gerilmez ve t\u00fcp \u00e7\u00f6ker, ovallik artar ve hatta i\u00e7 k\u0131s\u0131mda k\u0131r\u0131\u015f\u0131kl\u0131klar olu\u015fur.<\/p>\n

Mandrelin bir ilerleme miktar\u0131 olmal\u0131d\u0131r (te\u011fet noktas\u0131 \u00fczerinde). Bunu etkileyen bir\u00e7ok fakt\u00f6r vard\u0131r, \u00f6rne\u011fin: mandrelin \u00f6n R'sinin boyutu; b\u00fckme yar\u0131\u00e7ap\u0131n\u0131n boyutu; borunun i\u00e7 \u00e7ap\u0131 ile mandrel aras\u0131ndaki bo\u015fluk; vb.

Borunun i\u00e7 duvar\u0131n\u0131n \u00e7izilmesini \u00f6nlemek i\u00e7in, mandrel yeterli sertli\u011fe sahip olmal\u0131 ve dikkatlice \u00e7apak al\u0131nmal\u0131 ve cilalanmal\u0131d\u0131r; borunun i\u00e7 bo\u015flu\u011fu da dikkatlice temizlenmeli ve gerekirse \u0131slak kumlama yap\u0131lmal\u0131d\u0131r.<\/p>\n
