Iyo drill bit imhando yemidziyo inodyiwa yekuchera magadzirirwo, uye kushandiswa kweiyo drill bit mukugadzira mold yakanyanya kuwanda; yakanaka drill bit inokanganisawo mutengo wekugadzirisa we mold. Saka ndeapi marudzi akajairika eku drill bits mukugadzira mold yedu? ?
Chekutanga pane zvese, iyo yakakamurwa zvinoenderana neiyo dhiri dhiri, iyo inowanzo kupatsanurwa kuva:
High-speed steel drills (inowanzo shandiswa kune zvinyoro zvinyoro uye kuchera kwakashata)
Cobalt-ine drill bits (inowanzo shandiswa kugadzirwa kwegomba rakaomarara sesimbi isina tsvina uye titanium alloys)
Tungsten simbi / tungsten carbide drills (yepamusoro-kumhanya, yakakwirira-kuoma, yakakwirira-chaiyo gomba kugadzirisa)
Zvinoenderana neiyo drill bit system, kazhinji:
Straight shank twist drills (inonyanya kuzivikanwa rudzi rwekuchera)
Micro-diameter drills (special drills for small diameters, blade dhayamita inowanzova pakati pe 0.3-3mm)
Step drill (yakakodzera nhanho imwe kuumba maburi-matanho akawanda, kuvandudza kushanda zvakanaka uye kuderedza mari yekugadzirisa)
Zvinoenderana neinotonhora nzira, yakakamurwa kuita:
Kudhirowa kwakananga kunotonhora (kudururwa kwekunze kwezvinotonhorera, zviboorero zvakajairika zvinowanzo dhiraivha zvinotonhora)
Internal cooling drill (iyo drill ine 1-2 kutonhora kuburikidza nemakomba, uye inotonhorera inopfuura nemumakomba ekutonhodza, iyo inoderedza zvikuru kupisa kwechibhorani uye workpiece, yakakodzera kune yakakwirira-yakaoma zvinhu uye kupedza)
