Umgubo we-corundum omhlophe uyandisa njani ubomi benkonzo yezixhobo?
Yintoni eyona nto ibuhlungu kakhulu kwindawo eyomileyoukusika nokusilakushishino? Asikuko ukunyuka kwamatyala ombane okanye ubunzima bomsebenzi, kodwa zizixhobo ezifa ngokukhawuleza! Amavili okugaya, amabhanti okugquma, amatye eoyile, iidiski zokugaya… aba bantu baphila baza “kuwohloka” kwiintsuku ezimbalwa, kwaye endaweni yazo bafake ezintsha kufana nokusika inyama. Ingakumbi xa kucutshungulwa ezo zinto ziqinileyo zamathambo—intsimbi engatyiwayo, ii-alloys ezinobushushu obuphezulu, kunye nentsimbi eqinileyo, izixhobo ziyaguga ngokukhawuleza kangangokuba ungathandabuzi ngobomi bakho.
Molo, zihlobo zakudala, namhlanje masithethe ngendlela le nto incinci ingabonakaliyo,umgubo omhlophe we-corundum, iye yaba yindlela yokuphelisa “ubomi” bezixhobo? Andibaxi. Ukuba uyisebenzisa kakuhle, ayiqhelekanga ukuphindaphinda ubomi bezixhobo, kwaye imali egciniweyo yonke yimali yokwenyani!
“I-Blunt? Ndiza kuyilungisa!”–Isincedisi somlingo “esizilolayo”
Khawucinge: umaleko weenkozo ezirhabaxa phezu komphezuluivili lokusilaibuthuntu, kwaye ukusebenza kwayo kuncipha. Ngeli xesha, ukuba isakhiwo sevili lokusila sisasazwa ngokulinganayo nge-corundum powder emhlophe ecolekileyo, bafana "neqela eligciniweyo" elicashileyo.
Xa i-binder inxitywe kakuhle phantsi kwesenzo samandla okusila kunye nobushushu bokungqubana, la masuntswana e-micro-powder anethuba "lokubonisa iintloko zawo" aze atshintshe loo masuntswana makhulu aqinileyo ukuze enze kwakhona umda obukhali wokusika!
Oku kunciphisa kakhulu isantya somphezulu wevili lokusila lonke "njengomhlaba othe tyaba", okuvumela ivili lokusila ukuba lihlale libukhali ixesha elithile, amandla okusila awaboli, kwaye ukusebenza kakuhle kokucubungula kuzinzile. Indawo yethu yokusebenzela igoba iqela leeshafti ze-alloy ezinamandla aphezulu, kusetyenziswa amavili okusila e-ceramic axutywe ne-W10 micro-powder. Xa kuthelekiswa namavili okusila aqhelekileyo, kuthatha phantse umsebenzi ongaphezulu kwama-30% ukusila ngaphambi kokuba kufuneke kunqunyulwe. Umphathi wonwabile kakhulu.
Isitshixo sokusebenzisa i-micro-powder ukwandisa ubomi siseku "faniseni" kunye "nokusebenzisa"
I-micro-powder yinto elungileyo, kodwa ayisiyonto yokuphelisa iingxaki, kwaye ayisiyonto ingasetyenziswa ngokuyifafaza ngokungacwangciswanga. Ukuba ufuna ukuba idlale impembelelo emangalisayo yokwandisa ubomi, kufuneka uqaphele oku kulandelayo:
Khetha "iqabane" elifanelekileyo (ukulinganisa ubungakanani bamasuntswana): Ubungakanani bamasuntswanaumgubo omncinci (Inombolo ye-W) kufuneka ihambelane nobukhulu besuntswana le-abrasive ephambili (amasuntswana arhabaxa)! Ukuba irhabaxa kakhulu, isiphumo sokuzalisa kunye nokulola siya kuba sibi; ukuba ilungile kakhulu, isenokusongwa ngokupheleleyo yi-binder kwaye "ifuthaniswe" kwaye ayizukusebenza. Umthetho ophambili: Kufanelekile ukuba ubungakanani besuntswana le-micro powder bube malunga ne-1/5 ukuya kwi-1/3 yobukhulu besuntswana le-abrasive ephambili. Umzekelo, ukuba usebenzisa amasuntswana arhabaxa angama-46#, kungcono ukufanisa i-W20-W14 micro powder.
Yiqonde kakuhle “idosi” (umlinganiselo wokongeza): Ingakanani i-micro powder ekufuneka uyifake? Isiphumo esincinci kakhulu asibonakali, kwaye okuninzi kakhulu kunokuba yingozi, okuchaphazela amandla e-binder okanye ukwenza ivili lokusila libe nzima kakhulu. Olu mlinganiselo luxhomekeke kuvavanyo namava, kwaye ngokubanzi luhlengahlengiswa ngaphakathi koluhlu lwe-10%-30% yobunzima obupheleleyo be-abrasive. Amavili okusila e-resin anokongezwa kwi-20%-30%, kwaye amavili okusila e-ceramic ngokubanzi anele yi-10%-20%. Musa ukuba nzima ngenxa yezinto ezinamandla!
Khetha "ibala lemfazwe" (izixhobo ezifanelekileyo):
Izinto zokuqhobosha ezidityanisiweyo (amavili okugaya, amatye eoyile, iintloko zokugaya): Le yindawo ephambili yokulwa yokwandisa ubomi be-micropowder! Ifanelekile ngokukodwa kumavili okugaya aneebhondi ze-resin kunye neebhondi ze-vitrified. Ifomula kunye nenkqubo yokuxuba zezona zinto zibalulekileyo ukuqinisekisa ukuba i-micropowder isasazeke ngokulinganayo.
Izinto zokugquma ezigqumayo (iibhanti zesanti, iphepha lokugquma): Xa usenza iibhanti zesanti kunye nephepha lokugquma, ukongeza inani elincinci le-micropowder (njenge-5%-15% ye-abrasive iyonke) kwiglu esisiseko kunye neglue engaphezulu kunokuphucula kakhulu amandla okubamba amasuntswana okugquma, kuthintele amasuntswana okugquma ukuba angawi ngaphambi kwexesha, kwaye kuncede nasekuthinteleni ukuvaleka. Isebenza kakhulu ekwenzeni iibhanti zokugquma ngokuchanekileyo.
Ulwelo/uncamathiselo lokusila nokupolisha: Sebenzisa ngokuthe ngqoumgubo omncinci we-corundum omhlopheukulungiselela ulwelo lokusila okanye intlama yokupolisha ukuze kugqitywe kakuhle. Amasuntswana amancinci kakhulu kunye nokuqina okuphezulu kwe-micropowder kunokufumana iindawo ezifanayo kakhulu nezingonakalisi kakhulu, kwaye isixhobo (iphedi yokupolisha/ivili) ngokwaso siyaguga kancinci kakhulu.
