I-Welong Supply Chain, iyakwazi ukwenza iivili ze-BOHLER S390 ezinobunzima 65 ~ 69HRC kwizixhobo zokomba. I-BOHLER 5390 MICROCLEAN iveliswa ngeendlela ze-powder-metallurgy Ukwahlula-kwahlulwa kunye nomgubo wesinyithi olinganayo ubunyulu obuphezulu kunye negranulation eyaneleyo icutshungulwa kwi-homogeneous kunye nokwahlulwa-free high speed steels eziphantse zibe yipropathi ye-isotropic kwinkqubo yosasazo eyenzeka kuxinzelelo oluphezulu kunye namaqondo obushushu.
BOHLER S390 amavili kunokuba lukhuni. 1150 10 1230°((2102 ukuya ku-2246°F)
I-oyile, ibhafu yetyuwa (500- 550 ° C (932 -1022 ° F), umoya, igesi. Uluhlu oluphezulu lobushushu kwiindawo zemilo elula, esezantsi kwiindawo zemilo eyinkimbinkimbi. . Ixesha lokufunxa emva kokufudumeza icandelo lonke le-workpiece imizuzwana engama-80 ubuncinane iyafuneka ekunyibilikiseni i-carbides eyaneleyo imizuzwana eyi-150 ukunqanda ukonakala ngokuntywila.
Kwinkqubo endaweni yokufunxa ixesha ixesha lokuvezwa ukusuka ekubekeni i-workpiece kwi-saith bath emva kokufudumeza kwangaphambili kude kube ngokususa (kubandakanywa nezigaba zokufudumeza kwiqondo lokushisa elichaziweyo kunye nokufudumeza kwiqondo lobushushu kulo lonke icandelo) lisetyenziswa. Ukuqina kwevacuum kunokwenzeka. Ixesha kwi-vacuum vacuum lixhomekeke kubukhulu obufanelekileyo bokusebenza kunye neeparamitha zesithando somlilo
Emva koko, amavili e-BOHLER S390 anokuba shushu. Ukufudumeza okucothayo kubushushu obupholileyo ngoko nangoko emva kokuqina / ixesha kwiziko: iyure e-1 kwi-20mm nganye yobukhulu be-workpiece, kodwa ingabi ngaphantsi kweeyure ezi-2 / ukupholisa komoya (ubuncinane bexesha lokubamba: iyure enye). I-1st tempering kunye ne-2nd ukucaphuka kubunzima obunqwenelekayo bokusebenza. Ubushushu besithathu bokunciphisa uxinzelelo, 30 ~ 50 ° C (86 ~ 122 ° F) ngaphantsi kobushushu bobushushu obuphezulu. Ubunzima obufumanekayo emva kokufudumala i-65 - 69 HRC.
Ngokuphathelele inkqubo yemveliso BOHLER S390 amavili: machining (chamfering) + iprofayili izinyo machining + unyango ubushushu. Nika ingqalelo ekhethekileyo ukushiya ubuncinci besibonelelo se-0.50mm kwelinye icala le-diameter yangaphandle ngexesha lokujika ukusika ucingo kumatshini weprofayili yezinyo.
Ukuba unazo naziphi na iimfuno okanye umbuzo malunga neForgings yeCones ye-drill Bit, nceda uzive ukhululekile ukuqhagamshelana nathi.
