Umatshini wokucima amaza aphezulu iimfuno zobulukhuni

Izinto eziphambili zobunzima bomatshini wokucima i-high-frequency: umxholo we-martensite kunye nomxholo wekhabhoni kwisakhiwo. Isizathu sobunzima obuphezulu bokucima inokuba kukuba ukucima kwiqondo lokushisa eliphezulu kwenza isakhiwo se-martensite esinqabileyo. Ngaphantsi kweemeko eziqhelekileyo, xa ukuqina komatshini wokucima umbane ophezulu, ukunciphisa ubushushu bokucima i-high-frequency quenching, ushiye ixesha elithile phambi kwesithando somlilo, kunye nokucima okusemgangathweni kulungile. Ezi zinokutshintsha ubulukhuni be-workpiece emva kokucima ngokuhambelana nobushushu bokucima. Ubunzima bentsimbi emva kokucima ubukhulu becala bunqunywe ngumxholo we-martensite kwintsimbi. Ifuthe eliphambili lobushushu bobunzima be-martensite ngumxholo wekhabhoni kwi-martensite.

Ukuba ubunzima bokucima umatshini wokucima i-high-frequency quenching ephezulu, ubunzima bunokunciphisa ngokunyusa ubushushu bokufudumala. Ngapha koko, kwintsimbi ecinyiweyo kunye nepholileyo efana ne-40Cr, okukhona ukuqina kokucima, kokukhona kuphezulu iipropathi zoomatshini emva kobushushu. Ubunzima obuphezulu bokucima akufuneki ukuba buncitshiswe ngokulungelelanisa iiparamitha zenkqubo yokucima kunye neemeko zokupholisa. Emva kokucima, inokusombulula ngokukhetha iqondo lokushisa elifanelekileyo.

Isizathu esona sizathu sobunzima obuphezulu emva kokucima kumatshini wokucima i-high-frequency quenching kukuba ubushushu bokucima buphezulu, kwaye izinga lokupholisa likhawuleza kakhulu. Kuphela ngokunciphisa ngokufanelekileyo ubushushu bokucima okanye ukwandisa indawo yokupholisa yokucima kunokuphuculwa. Kwizinto ezivuthiweyo, inkqubo yayo yonyango lobushushu yinkqubo evuthiweyo kwaye izinzile. Iqondo eliphezulu lokucima umatshini wokucima ubushushu, ixesha lokucima, ubushushu bokufudumala, ixesha lokufudumala, indlela yokucima kufuneka ibe yindlela emiselweyo.
