Drill Bits: Izvo Zvikamu Zvikuru zveChigadzirwa Chemhando

Drill bits maturusi akakosha kune akasiyana siyana maindasitiri, kubva pakuvaka kusvika kune matanda. Ivo vanouya muhukuru hwakasiyana uye zviwanikwa, asi pane akati wandei akakosha maficha anotsanangura yemhando yekudhirowa.

Chekutanga, zvinhu zveiyo drill bit yakakosha. High-speed steel (HSS) ndiyo inonyanya kushandiswa, sezvo yakasimba uye inogona kushandiswa kune zvakasiyana-siyana zvekuchera zvibodzwa. Cobalt simbi uye carbide-tipped drill bits zvakare yakakurumbira nekuda kwekugara kwayo uye kusapisa kupisa.

Chechipiri, dhizaini yedhiri yekubooresa yakakosha. Chimiro uye kona yetipi inogona kukanganisa kumhanya kwekuchera uye kurongeka. Iro rakapinza, rakanongedza muromo wakanakira kuchera kuburikidza nemidziyo yakapfava, nepo chidimbu-chakapfava chiri nani kune zvinhu zvakaomarara. Iko kona yetipi inogonawo kusiyana, ine makona akapinza achipa kukurumidza kuchera kumhanya asi kushoma kurongeka.

Chechitatu, shank ye drill bit inofanira kuva yakasimba uye inopindirana nemudziyo wekuchera. Mamwe madhiri ane shanks ane hexagonal, ayo anopa kusimba kwakasimba uye anodzivirira kutsvedza panguva yekuchera. Mamwe ane shanks dzakatenderedza, ayo akajairika uye anoshanda nemazvo kune akawanda ekuchera zvikumbiro.

Pakupedzisira, ukuru hwechibhorani hwakakosha. Inofanira kufanana nehukuru hwegomba rinodiwa purojekiti. Mabhiti ekudhira anouya muhukuru hwakasiyana, kubva kudiki diki kugadzira zvishongo kusvika kune mahombe ekuvaka.

Pamusoro pezvinhu zvakakosha izvi, pane zvimwe zvinofanirwa kutariswa pakusarudza chibooreso, serudzi rwechibooreso chiri kushandiswa uye rudzi rwezvinhu zviri kucherwa. Mamwe madhiri akagadzirirwa kuti ashandiswe nezvimwe zvinhu, zvakaita semasonry kana simbi.

Pakazere, chibooreso chemhando yepamusoro chinofanirwa kugadzirwa kubva kumidziyo yakasimba, iine yakanyatso dhizainiwa zano uye shank, uye ive saizi chaiyo yechinangwa chekuchera chikumbiro. Nezvimiro izvi mupfungwa, nyanzvi uye hobbyists zvakafanana vanogona kusarudza iyo chaiyo drill bit yemapurojekiti avo uye kuwana yakanakisa mhedzisiro.
