Dab tsi yog Drill Bits haum rau Stainless Hlau Punching?
Oct 29, 2025| Thaum machining stainless hlau raj phaj, laum cov khoom feem ntau ua rau mob taub hau, yuav tsum tau ua kom ntse ntse thiab qee zaum ua rau scrapping. Dab tsi ntawm qhov laum me ntsis tuaj yeem zam cov teeb meem no?
Ua ntej, peb yuav tsum nkag siab txog kev ua cov yam ntxwv ntawm stainless hlau. Stainless hlau muaj zog plasticity thiab siab toughness, tab sis thaum lub sij hawm drilling, nws nto hardens ho, thiab txiav kub yog siab. Thaum drilling, twist xyaum yog nyob ib puag ncig los ntawm hardened nto ntawm stainless hlau, ua kom sov dissipation nyuaj thiab ua rau lub laum me ntsis yooj yim lo.
Yog li ntawd, rau stainless hlau drilling, lub laum me ntsis yuav tsum muaj siab hardness thiab zoo heev nto tiav. Lub kaum sab xis ntawm lub laum me ntsis yuav tsum loj dua li ntawm tus qauv xyaum (nruab nrab ntawm 130-135 degrees). Tsis tas li ntawd, yuav tsum tau ua kom txias txias, thiab tus nqi pub yuav tsum siab tshaj 0.15 hli kom txo qis hauv cov txheej txheem ua haujlwm. Thaum drilling stainless hlau, qhov ceev yuav tsum tau txo kom ntau li ntau tau kom txo tau qhov drilling kub, thaum siv emulsion coolant ua ke.
Feem ntau siv cov laum me me rau cov hlau tsis muaj steel drilling xws li: siab cobalt twist xyaum (M35 twist xyaum, M42 twist xyaum), nrog M42 siab cobalt twist xyaum muab cov nqi zoo dua. Xwb, hloov tau carbide-tipped laum khoom kuj siv tau, txawm tias lawv kim dua.
Coated twist xyaum yog twist xyaum uas muaj cov tshuaj lom neeg cobalt (Co). Lub hom phiaj ntawm kev ntxiv cobalt (Co) yog txhawm rau txhim kho qhov siab -kub tsis kam thiab hnav tsis kam ntawm kev sib tw twist, ua kom muaj kev vam meej drilling los ntawm stainless hlau nto. Coated twist xyaum tau muab faib ua ob hom: qis-cobalt thiab siab-cobalt, nrog rau cov khoom xws li M35 thiab M42. Piv rau cov kev xyaum sib tw zoo tib yam, coated twist xyaum yog nyuaj tab sis ntau nkig.
Qhov hloov tau carbide crown laum me ntsis yog lub cim tshiab ntawm cov cuab yeej drilling. Nws muaj ib lub cev xyaum steel thiab ib tug hloov ib tug carbide crown, ua tiav ib tug machining precision ntawm yim thiab ib nrab phaus. Txawm li cas los xij, txij li lub crown yog hloov tau, nws txo cov nqi machining thiab txhim kho cov khoom lag luam drilling. Qhov laum me me no tuaj yeem ua tiav lub qhov taub ntawm qhov sib ntxiv thiab nta nws tus kheej -centering functionality, ua rau siab machining raug rau lub qhov diameters.
