Muaj pes tsawg txheej txheej rau HSS laum ntsis? thiab qhov twg zoo dua?

High-speed steel (HSS) laum cov khoom feem ntau muaj cov txheej txheem sib txawv tsim los txhim kho lawv cov kev ua tau zoo thiab ua haujlwm ntev. Feem ntau cov txheej txheej txheej rau high-speed steel laum khoom suav nrog:

1. Dub Oxide Txheej: Cov txheej no muab cov qib ntawm corrosion kuj thiab pab txo kev sib txhuam thaum lub sij hawm drilling. Nws kuj tseem pab khaws cov roj nplua nyeem ntawm lub laum nto. Dub oxide coated laum khoom yog tsim rau lub hom phiaj dav dav hauv cov ntaub ntawv xws li ntoo, yas thiab hlau.

2. Titanium Nitride (TiN) Txheej: TiN txheej tsub kom hnav tsis kam thiab pab txo kev sib txhuam, yog li txuas ntxiv lub neej ntawm cov cuab yeej thiab txhim kho kev ua haujlwm hauv cov ntawv thov kub kub. TiN coated laum khoom yog tsim rau drilling cov ntaub ntawv nyuaj xws li stainless hlau, cam khwb cia hlau, thiab titanium.

3. Titanium carbonitride (TiCN) txheej: Piv nrog TiN txheej, TiCN txheej muaj ntau dua hnav tsis kam thiab kub tsis kam. Nws yog tsim rau drilling abrasives thiab high-temperature cov ntaub ntawv los txhim kho lub neej ntawm cov cuab yeej thiab kev ua tau zoo nyob rau hauv kev thov drilling daim ntaub ntawv.

4. Titanium aluminium nitride (TiAlN) txheej: TiAlN txheej muaj qib siab tshaj plaws ntawm kev hnav tsis kam thiab kub tsis kam ntawm cov txheej saum toj no. Nws yog tsim rau drilling hardened steels, high-temperature alloys thiab lwm yam nyuaj cov ntaub ntawv los mus cuag lub neej cuab tam thiab txhim kho kev ua tau zoo nyob rau hauv nyuaj drilling tej yam kev mob.

Qhov txheej twg zoo dua yog nyob ntawm daim ntawv thov tshwj xeeb drilling thiab cov khoom siv tho. Txhua txheej muaj qhov tshwj xeeb zoo thiab yog tsim los rau ntau hom ntaub ntawv thiab drilling tej yam kev mob. Rau lub hom phiaj dav dav drilling hauv cov ntaub ntawv sib xws, ib qho dub oxide coated laum me ntsis yuav txaus. Txawm li cas los xij, rau kev thov ntau ntxiv uas muaj cov ntaub ntawv nyuaj lossis cov khoom kub kub,TiN, TiCN los yog TiAlN coated laum cov khoom yuav tsim nyog dua vim lawv cov kev txhim kho hnav thiab kub ua hauj.
