Asme Aircraft Extension HSS Drill Bit
Khoom Qhia
Lub dav hlau txuas ntxiv laum cov khoom muaj zog dua li cov khoom siv uas muaj grooves raws lawv qhov ntev.Rau drilling qhov nyob rau hauv tawv, siab tensile zog cov ntaub ntawv xws li stainless hlau, titanium thiab Inconel.Zoo tagnrho rau drilling aluminium thiab nruab nrab mus rau qis steel alloys.Dub oxide kho HSS txhim khu kev tiv thaiv tshav kub thiab txuas ntxiv lub neej ntawm cov cuab yeej, nrog cov txheej txheem oxide txheej txheej dua li cov oxide dub feem ntau siv los txheeb xyuas cov cuab yeej cobalt steel;kev ua tau zoo zoo ib yam li cov cuab yeej tsis muaj coated.Lub caij nplooj ntoos hlav-tempered shank tiv thaiv kev khoov mus tas li thaum drilled qhov tsis ncaj nraim.Round shanks tuaj yeem siv nrog ntau yam cuab yeej siv tshuab.
Ib qho kev xyaum nrog qhov sib cais ntawm 118- lossis 135 degrees txhais tau hais tias yuav tsum muaj lub zog qis dua rau hauv qhov chaw ua haujlwm, tiv thaiv kev xyaum los ntawm zawv zawg ntawm cov khoom siv, nws tus kheej-center thiab txo cov thrust xav tau rau drilling.Ntxiv rau qhov drilling steel, aluminium thiab stainless hlau, qhov laum no tseem tuaj yeem siv los laum ntoo, hlau, thiab lwm yam ntaub ntawv, vim nws yog tsim los ntawm high-speed steel.Tsis tas li ntawd, nws tseem tuaj yeem siv los laum ntau lwm cov ntaub ntawv los ntawm tes, uas ua rau nws yog ib qho ntawm cov cuab yeej siv tau zoo tshaj plaws.
