Kev khoov thiab kev tsim cov ntawv hlau yog nqa tawm ntawm lub tshuab dabtsi yog khoov. Muab lub workpiece tsim rau ntawm lub tshuab dabtsi yog khoov, siv lub lifting lever los nqa lub brake khau, xaub lub workpiece mus rau txoj hauj lwm tsim nyog, thiab tom qab ntawd txo tus brake khau rau txoj hauj lwm xav tau. Ntawm lub workpiece tsim, cov hlau yog khoov thiab tsim los ntawm kev siv lub zog rau lub zog khoov ntawm lub tshuab dabtsi yog khoov. Qhov tsawg kawg nkaus khoov vojvoog yog qhov ua haujlwm ntawm qhov ductility thiab thickness ntawm cov hlau tsim. Rau cov phaj aluminium, lub vojvoog dabtsi yog khoov ntawm cov hlau yog loj dua li lub thickness ntawm lub phaj. Thaum khoov, vim muaj qee qhov kev thim rov qab, lub kaum sab xis ntawm cov hlau yog khoov me ntsis loj dua qhov xav tau lub kaum sab xis. Kev khoov ntawm cov ntawv hlau yog ua nyob rau hauv kev cob qhia hlau.
Sheet hlau ua tsuas yog cov txheej txheem xws li khoov, riveting, thiab vuam cov ntaub ntawv hlau. Cov hauv qab no yog cov teeb meem thiab cov kev daws teeb meem uas tau ntsib hauv cov txheej txheem khoov thaum lub sij hawm ua cov ntawv hlau.
