Ingamba zo kwirinda kuvunika vis zo kwicukura
Kuvunika kw'ipfundo ryavunitse, umurizo wavunitse, inkoni yavunitse, bikunze kubaho muri screw ya martensitic carbon steel, screw ya martensitic carbon steel ikoresha ubushyuhe bwinshi bwo hejuru bwa carbonitriding face igera kuri ≥560HV, hamwe n'ubwinjiriro bukomeye, ariko nanone byongera ububobere bw'iscrew. Iyo screw ya self-drilled mu gihe cy'umutwaro ukabije, torque ikabije, gutigita byoroshye bibaho. Iyo screw ya self-drilled ivunitse, ntabwo bigira ingaruka gusa ku iterambere ry'inyubako, ntabwo ari nziza, ahubwo bizana ingaruka nyinshi ku mutekano. Hari ibintu bikurikira cyane cyane kugira ngo hirindwe ko screw ya drilled ivunitse:
1: Hitamo ibicuruzwa bikwiye
a: Mbere yo gukoresha, banza wemeze niba imiterere y'ibicuruzwa ishobora kuzuza ibisabwa mu ikoreshwa ryabyo.
b: Guhitamo neza ingano n'uburebure bya vis
C: Ni byiza gukoresha igice cy'amenyo cyangwa amenyo abiri mu bidukikije bihuza
2: Koresha inomero
A: Koresha vis 4-6 kuri metero kare
B: Umubare w'igisenge n'isahani nini bigomba kongerwa uko bikwiye
C: Agace k'umuyaga ni kanini, komeza ingano ikwiye
3: Uburyo bwiza bwo gukoresha
A: Kanda ku ruhande rugororotse ku murongo w'umugozi, ntugahindukire
B: Mu gikorwa cyo gukaza, imbaraga zigomba kuba zingana, kandi imbaraga zo gukaza ntizigomba kurenza imbaraga z'umutekano
C: 12#, 14# ibikoresho bigena imiterere, umuvuduko w'imashini zikoresha amashanyarazi 1000-1800 revolution ntabwo ishobora kuba yihuta cyane
4: Igipimo cy'ingufu (hasi y'amakuru akoreshwa gusa):Nm
