Ukusebenza emva kokuqina kwetyala lokungeniswa

1. Ukuqina komphezulu: Ukuqina komphezulu wezixhobo zokusebenza eziphantsi kokucinywa kobushushu obuphezulu naphakathi buhlala buziiyunithi ezi-2 ukuya kwezi-3 (HRC) ngaphezulu kunokucima okuqhelekileyo.

2. Ukumelana nokunxiba: Ukumelana nokunxiba kwesixhobo sokusebenza emva kokucinywa kwamatyeli aphezulu kuphezulu kunokucima okuqhelekileyo. Oku kungenxa yeziphumo ezidityanisiweyo zeenkozo ezintle zemartensite kumaleko oqina, ukusasazeka kwe-carbide ephezulu, ubunzima obuphezulu, kunye noxinzelelo oluphezulu loxinzelelo kumphezulu.

3. Amandla okudinwa: ukucima umphezulu ophakamileyo kunye nophakathi kuphucula kakhulu amandla okudinwa kwaye kunciphisa uvakalelo lwenotshi. Kuba workpieces of the material efanayo, ubunzulu umaleko lukhuni ngaphakathi kuluhlu oluthile, kwaye amandla ukudinwa kwandisa ngokunyuka ubunzulu umaleko lukhuni, kodwa xa ubunzulu umaleko lukhuni kakhulu, umaleko womphezulu. luxinzelelo olucinezelayo, ngoko ukwanda kobunzulu bomaleko obunzima kunciphisa amandla okudinwa kwaye kwenza i-workpiece. Ubuqhophololo buyanda. Ubunzulu bomaleko owenziwe lukhuni ngokubanzi δ = (10 ~ 20)% D. ifaneleke ngakumbi, apho i-D. iyidayamitha esebenzayo yesixhobo sokusebenza.
