Zachikhalidwe zathu za 450x71njanji zofukulaamagwiritsidwa ntchito ndi makina oyenda pansi pa galimoto omwe amapangidwira kuti azigwira ntchito pa njanji za rabara. Njira za rabara zachikhalidwe sizikhudzana ndi chitsulo cha ma roller a zidazo pamene zikugwira ntchito. Kusakhudzana ndi chipangizocho kumabweretsa chitonthozo chowonjezereka kwa wogwiritsa ntchito. Ubwino wina wa njira za rabara zachikhalidwe ndi wakuti kukhudzana ndi zida zolemera kumachitika kokha pamene njira za rabara zachikhalidwe zikugwirizanitsa kuti roller isasokonezeke.

Zathunjanji zazing'ono zokumbiraAmapangidwa kuchokera ku zinthu zapadera za rabara zomwe sizimadulidwa kapena kung'ambika. Ma track athu ali ndi maulalo achitsulo chokha omwe adapangidwa ndi malangizo enieni kuti agwirizane ndi makina anu ndikuwonetsetsa kuti zida zikugwira ntchito bwino. Ma inserts achitsulo amadonthezedwa ndipo amaviikidwa mu guluu wapadera womangirira. Mukaviika ma inserts achitsulo m'malo mowapaka ndi guluu, pamakhala mgwirizano wolimba komanso wokhazikika mkati mwake; Izi zimatsimikizira kuti njanjiyo ndi yolimba kwambiri.

Momwe mungatsimikizire kukula kwa njira ya rabara yosinthira

Kawirikawiri, njanjiyo imakhala ndi sitampu yokhala ndi chidziwitso cha kukula kwake mkati. Ngati simukupeza chizindikiro cha kukula kwake, mutha kupeza chiyerekezo chake nokha potsatira muyezo wamakampani ndikutsatira njira zomwe zatchulidwa pansipa:

Yesani mtunda, womwe ndi mtunda wa pakati pa ma drive lugs, mu mamilimita.

Yesani m'lifupi mwake mu mamilimita.

Werengani chiwerengero chonse cha maulalo, omwe amadziwikanso kuti mano kapena ma drive lugs, mu makina anu.
Fomula yodziwika bwino yoyezera kukula kwa mafakitale ndi iyi:

Kukula kwa Njira ya Rabara = Pitch (mm) x Ufupi (mm) x Chiwerengero cha Maulalo
