Kusankha zinthu za chisel

Pankhani yosankha zinthu zopangira chisel, ndikofunikira kuganizira zamtundu ndi mawonekedwe azinthu zomwe zilipo. Pankhani ya 40Cr, 42CrMo, 46A, ndi 48A, chilichonse chili ndi mikhalidwe yakeyake yomwe imapangitsa kuti ikhale yoyenera kugwiritsa ntchito zosiyanasiyana. Nayi kalozera wamomwe mungasankhire zinthu zoyenera pa chisel chanu:

40Cr: Chitsulo chamtunduwu chimadziwika chifukwa champhamvu komanso kulimba kwake. Amagwiritsidwa ntchito kwambiri popanga tchipisi chomwe chimafuna kulimba komanso kukana kuti chisawonongeke. Ngati mukufuna chisel cha ntchito zolemetsa monga zitsulo kapena zomanga, 40Cr ikhoza kukhala chisankho choyenera chifukwa cha makina ake abwino kwambiri.

42CrMo: Chitsulo cha alloy ichi chimadziwika ndi mphamvu zake zambiri, kuuma bwino, komanso kukana kwambiri kuvala ndi kuyabwa. Zipangizo zopangidwa kuchokera ku 42CrMo ndizoyenera kugwiritsa ntchito zomwe zimafuna kukana kwambiri komanso kupirira katundu wolemetsa. Izi nthawi zambiri zimasankhidwa ngati tchipisi chomwe chimagwiritsidwa ntchito pomanga, migodi, ndi mafakitale ena ovuta.

46A: 46A chitsulo ndi carbon structural chitsulo chodziwika bwino weldability ndi machinability. Zovala zopangidwa kuchokera ku 46A ndizoyenera kugwiritsidwa ntchito pazifukwa wamba pomwe mphamvu ndi magwiridwe antchito zimafunikira. Ngati mukufuna chisel chosunthika chomwe chitha kupangidwa mosavuta ndikusinthidwa, 46A ikhoza kukhala njira yabwino.

48A: Chitsulo chamtunduwu chimadziwika chifukwa cha kuchuluka kwa kaboni, chomwe chimapereka kuuma kwambiri komanso kukana kuvala. Zovala zopangidwa kuchokera ku 48A ndizoyenera kugwiritsa ntchito zomwe zimafunikira m'mbali zakuthwa komanso magwiridwe antchito okhalitsa. Ngati mukufuna chisel kuti mugwire ntchito yolondola monga matabwa kapena zojambulajambula, 48A ikhoza kukhala chisankho choyenera.
