Xa kufikwa ekugayeni umphezulu wesinyithi, iseramikhi, okanye iplastiki, kukho izinto ezimbalwa ekufuneka uzikhumbule. Okokuqala, qiniseka ukuba usebenzisa isixhobo esifanelekileyo kulo msebenzi, nokuba yiblade yedayimani okanye ivili legrit. Kuya kufuneka uqwalasele nobungakanani bobushushu obusetyenziswa kwindawo yokusebenza, njengoko ukugaya nge-ceramic inokubangela iziphumo zokubola.
Iintlobo ezimbini eziphambili ze-abrasives ezisetyenziselwa ukugaya nokugqiba ukusetyenziswa zezendalo kunye nezenziwe ngokwenziwa. Umahluko ophambili phakathi kwezi zimbini yimvelaphi ye-abrasives. I-abrasives yendalo idla ngokwenziwa ngeeminerali ezifumaneka kwindalo. Ngelixa i-abrasives yokwenziwa yenziwe ngeekhemikhali zangaphambili.
Kukho iintlobo ezininzi ze-abrasives ezenziwe ngokwenziwa. Zahlukile ngokubhekiselele kumgangatho kunye nobunzima. Ezinye zilungele ngakumbi iintlobo ezithile zemisebenzi yokugaya okanye yokugqiba. I-Silicon carbide, okanye i-SiC, sisixhobo esidumileyo se-abrasives esenziwe ngokwenziwa. Nangona siguga ngokukhawuleza, esi sixhobo sihlala ixesha elide kwaye sibukhali kune-aluminium oxide.
Iibrasive zeseramikhi zihlala zenziwe ngomxube weeminerali zendalo nezenziwe ngumntu. Zingakhiwa zibe zizixhobo zokusika, amavili okugaya, kunye nezinye izixhobo emva kokuba zicutshungulwe kwaye zenziwe ngendlela ethile. iibhola zokusila ceramic sele ifumaneka kwimarike.
Iimpawu zomphezulu kunye nokusebenza kokuzilola ngokwazo kweentlobo ezimbini zamavili okusila edayimani ane-microtextured brazed end grinding kuthelekiswa kolu phononongo. Iskimu se-TG-G sisusa ii-microgrooves kuphela, ngelixa iskimu se-TG-GH sisusa ii-microgrooves kunye nee-microholes. Zombini iiskimu zinobume obufanayo bomphezulu, kodwa i-TG-GH isebenza ngcono ngokubhekiselele ekuziloleni ngokwazo.
Kusetyenziswa i-laser eshukumayo, ii-microtextures zaqala zasuswa kwiinkozo zedayimani. Oku kwalandelwa kukuqiniswa ngobuchule ukuze kwenziwe amavili okusila. La mavili aqhotsiweyo emva koko afakwa kwisibambi sezixhobo aze asetyenziswe ngomatshini ngesantya sokutya se-100 mm/s.
I-monocrystal diamond (111) plane yi-cleavage plane yedayimani ezirhabaxa. I-cleavage plane yi-abrasive grain void okanye indawo engenanto. I-cleavage plane idla ngokuhambelana necala lokusika, kodwa kukho izinto ezimbalwa ezahlukileyo. Olunye uhlobo lwemveliso olufumaneka kwimarike yi- ibhola yokugaya ye-alumina ceramic.
Injongo yolu phononongo yayikukuthelekisa iimpawu zomphezulu weendlela ze-TG-G kunye ne-TG-GH. Zininzi izinto ezinegalelo kulo mahluko. Umahluko kuburhabaxa bomphezulu, umzekelo, ubalwe.
Ngokweziphumo, indlela ye-TG-GH ivelise uburhabaxa obuncinci kunye nomahluko omncinci phakathi kwe-peak-to-peak kumandla okusika. Ngaphezu koko, ixabiso le-S eliveliswe yindlela ye-TG-GH laliphantsi. Kwakhona kwaphumela kwiindawo ezithambileyo. Ngaphezu koko, indlela ye-TG-GH ivelise imiphetho emininzi, nto leyo enciphise amandla okusika.
Ngokwezi ziphumo, ivili lokugaya le-TG-GH elinee-microgrooves kunye nee-microholes lidlula ivili lokugaya le-TG-G elinee-microgrooves. Ngaphezu koko, i-TG-GH iphumelele ngaphezu kwe-TG ngokuzilola ngokwayo. Nangona kunjalo, ezinye iinkozo zedayimani kwi-TG-G zibonise ukuqhekeka okukhulu. Olunye uhlobo lwemveliso olufumaneka kwimarike yi-
Iiseramikhi zineempawu ezininzi, kodwa kukho iingxaki eziqhelekileyo ekufuneka ziqwalaselwe xa kusenziwa ezi zinto. Okokuqala, inkqubo yokuvelisa ngokwayo inokuba nzima. Okwesibini, ezi zinto zinokuba nzima ukuzisebenzisa ngomatshini. Okwesithathu, ezi zinto zinokutsha, nto leyo ebeka umngcipheko wokhuseleko. Ngenxa yoko, ukhuseleko lomntu lubalulekile. Iiseramikhi, ngethamsanqa, zinokufumaneka kumashishini amaninzi.
Izixhobo zoomatshini bokusika i-ceramic zahlulwe zibe ziindidi ezimbini. Izixhobo zoomatshini ezikhawulezayo ezifana i-ball mill yeeseramikhi zibandakanyiwe kudidi lokuqala. Zingasika izinto ezinobunzima obuphezulu be-HRC65. Nangona kunjalo, ezi zixhobo zinokumelana okuncinci kwempembelelo.
Uhlobo lwesibini lwesixhobo seso senzelwe ngokukodwa ukwenza imisebenzi yokusila. Ezi zixhobo zinokusila zize zisike uluhlu olubanzi lwezinto, kwaye zinokugcina uzinzo lweekhemikhali kwiindawo ezinobushushu obuphezulu.
Iziko lokuvelisa laseTencan lisasazeke kumgama weemitha zesikwere ezingama-20,000 kwaye iziko lalo lophando nophuhliso liziimitha zesikwere ezingama-2,000. Oku kuthetha ukuba iTencan inokuhlangabezana nazo zonke iimfuno zabathengi. ITencan liqabane loogqirha abangama-20 kwaye inikwe amalungelo obunikazi angaphezu kwama-30.
Umsebenzi ophambili wale nkampani zizixhobo zokwenza ipowder, iteknoloji yepowder eyaziwa ngokuba zizixhobo zepowder. Iimveliso zethu eziphambili ngoku ziquka zonke iintlobo zee-ballmills zelabhoratri kunye noomatshini bokutyumza nokugaya, izixhobo zokuxuba nokuhlola, kunye nezinye izixhobo zelabhoratri ezifana neebhokisi zeglavu, izixhobo zesayensi, kunye nezinye izixhobo.
Le nkampani iqinisekiswe yi-ISO9001, CE, SGS kunye nezinye iziqinisekiso. Ikwanazo neepatenti ezingaphezu kwama-40 ezikhuselweyo ngamalungelo obunikazi obuzimeleyo. Urhulumente uyenze "ishishini lobuchwepheshe obuphezulu ngaphakathi kwiPhondo laseHunan".
Abathengi abaphambili baquka amaziko ophando, iiyunivesithi kunye neenkampani ezisekelwe kubuchwepheshe. Bakhonza abathengi abangaphezu kwama-20,000 kwihlabathi liphela kwaye bathumela kumazwe angaphezu kwama-60.
Ukusila iidayimani yindlela yokugqiba yobuchwepheshe obuphezulu yokuphucula umgangatho womphezulu kunye nokuqinisa ukunyamezelana kobukhulu kwiiseramikhi zobugcisa. Oku kwenziwa ngevili lesinyithi elicinezelwe ngokubandayo elineziqwenga zedayimani ezidityanisiweyo.
Ukusila kudla ngokwenziwa ngesantya esicothayo se-micron enye ngephasi nganye. Ngenxa yoko, iimpawu zoomatshini zezinto ziyagcinwa. Ngenxa yoko, umphezulu ugqitywa ngokukhawuleza. Ukugqitywa komphezulu, kwelinye icala, kuyaguga kwaye kunokuchaphazeleka kukutshintsha kwamandla okusila. Ukuchonga iindlela zokususa izinto ezisebenzayo, kufuneka uhlalutyo olucwangcisiweyo lweeparameter zobugcisa.
Uphando lokuqala lomonakalo womphezulu lubonise ukuba imida yeenkozo yayisengozini yokonakala. Ngaphezu koko, kwaphawulwa ukuba izinto ezisetyenzisiweyo zinobuthathaka ekuveliseni ubushushu. Olunye uhlobo lwemveliso ekhoyo kwimarike yi
