Cov khoom siv ntawm rab riam yog T12A high-carbon tool steel, thiab hardness tom qab quenching yog RC60 ~ 65. Rau lub hom phiaj ntawm kev txuag, nruab nrab carbon steel yuav siv tau raws li riam lub cev, thiab ib feem ntawm high carbon steel cutter taub hau yuav welded nyob rau hauv pem hauv ntej.
Tseem muaj cov scrapers ua los ntawm high-speed steel, hom riam thib ob no muaj kev hnav zoo, tab sis lub sharpening yog qhov nyuaj dua, thiab riam ntug tsis yooj yim rau zom, yog li nws tsis tshua siv dav.
Qee qhov xwm txheej, vim muaj kev txwv cov khoom siv, pov tseg cov hniav ntawm lub tshuab sawing, los yog nyias disc milling inserts tuaj yeem siv los ua lub taub hau txiav, welded rau ntawm lub cutter lub cev los ua cov cutters thib ob. Nws tseem tuaj yeem ua rau scrapers los ntawm cov ntaub ntawv qub. Cov ntaub ntawv muaj cov hniav thiab ua rau tawg thaum lub sij hawm forging txheej txheem. Yog li ntawd, cov ntaub ntawv yuav tsum tau smoothed ua ntej forging los tiv thaiv cov kab nrib pleb. Los yog ncaj qha annealed nrog cov ntaub ntawv, npaj los yog sharpened rau qhov xav tau loj. Forging scrapers los ntawm cov ntaub ntawv npaj tau yuav tsum tau ceev faj tsis txhob tsim cov kab nrib pleb, thiab cov scrapers tawg tsis tuaj yeem siv.
