Izinyathelo zokuphepha zokufakwa kwe izingxenye zokucubungula i-mica yobulili obuhlukile

1. Ngaphambi kokuhlanganisa, qiniseka ukuthi akukho lutho lwangaphandle ebusweni bomkhono we-shaft kanye nembobo yesihlalo, futhi ingaphezulu lembobo yesihlalo kufanele libe bushelelezi ngangokunokwenzeka ukuze ugweme imihuzuko ngesikhathi sokuhlanganiswa.

2. Amafutha okugcoba afanelekile angasetshenziswa endaweni yangaphandle yomkhono we-shaft ngesikhathi sokuhlanganiswa ukuze usize umkhono we-shaft ufakwe kalula, kodwa akulula ukuba ube mkhulu kakhulu ukuvimbela umkhono we-shaft ukuba ungawi ngesikhathi somthwalo osindayo noma. ukunyakaza okuvumelanayo.

3. Lapho uhlanganisa, i-mandrel kufanele icindezelwe kancane kancane, futhi inqatshelwe ukungqongqoza emkhonweni ukuze ugweme ukuguqulwa.

4. Ukuze wenze umhlangano ube lula futhi ukusika ngeke kulimaze isendlalelo esingagugi, ubuso bokuphela kwe-shaft kufanele bube bushelelezi futhi bushelelezi. Okubalulekile kwe-shaft kunconywa ukuthi kube indawo yensimbi ecinywe i-HRC45, ubulukhuni obungaphezulu bungu-Rz2-3, futhi indawo engaphezulu ingagqitshwa nge-chrome eqinile.
