Mangani ekuputira pamusoro peHSS drill bit? uye ndechipi chiri nani?

High-speed steel (HSS) drill bits inowanzova neakasiyana machira epamusoro akagadzirirwa kuvandudza kushanda kwavo uye kusimba. Izvo zvinonyanya kuvharidzirwa pamusoro pepamusoro-yepamusoro-speed steel drill bits dzinosanganisira:

1. Black Oxide Coating: Uku kupfekedza kunopa dhigirii rekusagadzikana uye kunobatsira kuderedza kukwesha panguva yekuchera. Inobatsirawo kuchengetedza lubricant pachibhorani. Black oxide coated drill bits akakodzera kune yakajairika chinangwa kuchera mumidziyo yakaita sehuni, plastiki nesimbi.

2. Titanium Nitride (TiN) Coating: TiN coating inowedzera kupfeka kuramba uye inobatsira kuderedza kupokana, nekudaro ichiwedzera hupenyu hwematurusi uye nekuvandudza mashandiro mukuchera-tembiricha yekuchera maapplication. TiN coated drill bits akakodzera kuchera zvinhu zvakaoma sesimbi isina tsvina, iron iron, uye titanium.

3. Titanium carbonitride (TiCN) kupfeka: Kuenzaniswa neTiN coating, TiCN coating ine yakakwirira kupfeka kusagadzikana uye kupisa kupisa. Yakakodzera kudhiraivha mabrasives uye yakakwirira-tembiricha zvinhu kuvandudza maturusi ehupenyu uye kuita mukuda kudhirowa zvikumbiro.

4. Titanium aluminium nitride (TiAlN) yekuputira: TiAlN yekuputira ine yepamusoro yepamusoro yekupfeka kusagadzikana uye kupisa kupisa pakati pezvipfeko zviri pamusoro. Yakakodzera kuchera masimbi akaomeswa, alloys epamusoro-tembiricha uye zvimwe zvinhu zvinonetsa kuti uwedzere hupenyu hwematurusi uye kuvandudza mashandiro mumamiriro akaoma ekuchera.

Ndeipi coating iri nani inotsamira pane chaiyo yekuchera application uye zvinhu zviri kucherwa. Imwe neimwe yekuputira inopa yakasarudzika mabhenefiti uye yakagadzirirwa marudzi akasiyana ezvigadzirwa uye mamiriro ekuchera. Nechinangwa chekuchera mune zvakajairika, chibooreso cheblack oxide chinogona kukwana. Nekudaro, kune zvimwe zvinodikanwa zvikumbiro zvinosanganisira zvakaoma kana zvakanyanya-tembiricha zvinhu,TiN, TiCN kana TiAlN yakavharidzirwa mabheti ekubooresa anogona kuve akakodzera zvakanyanya nekuda kwekunatsiridza mapfekero uye nekupisa.
