Peb Yam Tseem Ceeb ntawm Drill Bit Materials
Cov khoom siv ntawm lub laum me ntsis ncaj qha cuam tshuam rau kev ua haujlwm ntawm drilling thiab lifespan. Cov ntaub ntawv tseem ceeb tuaj yeem muab faib ua peb pawg:
High-Speed Steel (HSS): Tus nqi siab-kev ua tau zoo, haum rau kev siv hlau thiab ntoo, ua haujlwm kub zoo tab sis nruab nrab hardness.
Carbide: Tungsten carbide puag muab qhov zoo tshaj plaws hardness, haum rau cov ntaub ntawv nyuaj thiab nkig xws li cov vuas thiab pob zeb, tab sis kuj nkig.
Coated Materials: Ib txheej titanium los yog nitride yog siv rau cov khoom siv hauv paus, tuav lub zog thaum txhim kho qhov tawv tawv, haum rau precision machining.
Lub tswv yim rau xaiv txoj cai Drill Bit raws li cov khoom siv
Cov ntaub ntawv sib txawv xav tau cov khoom siv tho me ntsis:
Ntoo / Yas: Ib txwm siab - steel ceev yog txaus; xyuas kom lub txiav ntug kaum ntse ntse.
Hlau / cam khwb cia hlau: Siv cobalt - muaj siab - ceev steel los yog carbide, yuav tsum tau siab liab hardness.
Pob zeb / Pob zeb: Carbide laum cov khoom yog qhov tseem ceeb, nyiam dua nrog cov qauv txiav ntug.
Iav/Ceramics: Xaiv pob zeb diamond-coated los yog tungsten carbide tshwj xeeb laum khoom.
Tswv yim tswv yim rau Extending Lifespan
Kev siv kom raug tso cai rau kev xyaum ua haujlwm ntawm lawv qhov zoo tshaj plaws:
Tswj kom tsim nyog kev sib hloov ceev: 200-500 rpm rau hlau, thiab tshaj 1000 rpm rau ntoo.
Txias: Siv cov kua txiav thaum ua cov hlau los tiv thaiv kev kub siab - kub annealing.
Tsis tu ncua sharpening: Siv ib tug tshwj xeeb sharpening pob zeb los kho lub txiav ntug thiab rov ua hauj lwm txiav.
Sib cais cia: Khaws cov khoom sib txawv ntawm cov khoom sib txawv kom tsis txhob muaj kev puas tsuaj los ntawm kev sib tsoo.
