Choyamba, kwa nsalu zosiyanasiyana ndi zofunika nsalu kusankha lolinganacam chopindika. Chifukwa mlengi wa nsalu kalembedwe kufunafuna osiyana, kutsindika osiyana, koterocam ntchito pamwamba pamapindikira adzakhala osiyana.
Chifukwa cha singano kapena siker ndicam chizindikiro cha nthawi yayitali cha kukangana kothamanga kwambiri, mfundo za munthu aliyense nthawi imodzi ziyeneranso kupirira kukhudzidwa kwakukulu, koterocam Kusankhidwa kwa tikiti yadziko lonse Cr12MoV, zinthuzo ndizovuta kwambiri, kusinthika kwamoto, kusinthika kwamoto, kuuma kwamoto, mphamvu, kulimba ndizoyenera kwambiricamzofunika.cam Kuzimitsa kuuma nthawi zambiri kumakhala HRC63.5±1. cam kuuma kwambiri kapena kutsika kwambiri kudzakhala ndi zotsatira zoyipa.
cam curve pamwamba roughness ndizofunikira kwambiri, zimatsimikizira ngaticam ndi yabwino komanso yokhazikika.cam curve pamwamba roughness, ndi zida processing, zida, processing luso, kudula ndi zinthu zina zambiri za chisankho (opanga aliyensecam mtengo ndi wotsika kwambiri, nthawi zambiri mu ulalo uwu kuti mupange zolemba).cam ntchito yokhotakhota ndi roughness nthawi zambiri imatsimikiziridwa ngati Ra≤0.8m ku. ntchito pamwamba roughness si anachita bwino adzachititsa akupera singano chidendene, kugunda singano, pakona mpando Kutenthetsa ndi zochitika zina.
Komanso, komanso kulabadiracam dzenje udindo, keyway, mawonekedwe ndi pamapindikira wa udindo wachibale ndi kulondola, chidwi izi si zingabweretse mavuto.
