1. Dhora simbi

Kuchera simbi kunowanzova demadrill bit, uye chibooreso chinowanzogadzirwa nesimbi yakakwirira-kumhanya.Kazhinji simbi zvinhu (alloy simbi, non-alloy simbi, cast iron, cast simbi, non-ferrous simbi), metalworking drill bits anoshandiswa pamwechete.

Zvisinei, chenjerera kuchera pamusoro pesimbi.Iyo yekumhanyisa haifanirwe kunge yakanyanya kukwirira, zviri nyore kupisa drill bit.Ikozvino kune mamwe magoridhe akaputirwa neasingawanzo simbi yakaoma mafirimu kunze, ayo akagadzirwa nesimbi yemidziyo nezvimwe zvinhu, izvo zvinoomeswa nekupisa kupisa.Iro remuromo rinogadzikwa pamakona akaenzana kumativi ese uye rakadzokororwa zvishoma kuti riite acute edge.Simbi, iron uye aluminium izvo zvisina kuomeswa nekupisa kurapwa.Pakati pazvo, aluminium iri nyore kunamatira kune chibooreso uye inoda kuzorwa nemvura ine sipo pakuchera.

2. Dhonza kongiri

Kuboora maburi pakongiri nematombo, shandisa chibooreso chine chibooreso chematombo, uye musoro wekucheka unowanzo gadzirwa necarbide.Mhuri dzemazuva ose dzinoshandisa chibooreso chemaoko 10mm pane kuchera pamadziro esimende.

3. Dhonza huni

Dhonza maburi muhuni nechibooreso chehuni.Iyo yehuni yekugadzira drill ine yakakura yekucheka vhoriyamu uye haidi yakakwira chishandiso kuoma.Chishandiso chacho chinowanzova simbi inomhanya kwazvo.Kune kapipi kadiki pakati pechibooreso, uye diagonal angles pamativi ese ari maviri akakura, kana kunyange asina kona.Inoshandiswa senzvimbo yakagadziriswa.Kutaura zvazviri, zvibooreso zvesimbi zvinogonawo kuchera huni.Nokuti huni hunopisa nyore nyore uye brittle chips haisi nyore kudhonza kunze, unofanira kunonoka uye kuchenesa machipisi nguva nenguva.

4. Dhonza tile negirazi

Tiledrill bitsanoshandiswa kuchera makomba pamatairi eceramic uye magirazi ane kuoma kwepamusoro.Iyo yekushandisa inogadzirwa ne tungsten-carbon alloy.Nekuti chishandiso chine kuomarara kwakanyanya uye kushomeka kwakashata, chinoda kushandiswa nekumhanya kwakaderera uye pasina kukanganisa.
