Ama-Burrs ayinkinga evamile ekucutshungulweni kwensimbi. Kungakhathalekile ukuthi kusetshenziswa yiphi impahla enembayo, ama-burrs azokwakheka emkhiqizweni wokugcina. Ziyizinsalela zensimbi ezeqile ezidalwe emaphethelweni ezinto ezicutshunguliwe ngenxa yokuguquguquka kwepulasitiki, ikakhulukazi ezintweni ezine-ductility noma eziqinile.
Izinhlobo eziyinhloko zama-burrs zihlanganisa ama-flash burrs, ama-burrs abukhali, nama-splashes. Lezi zinsalela zensimbi eziphumela ngaphandle azihlangabezani nezidingo zomklamo womkhiqizo. Njengamanje, ayikho indlela ephumelelayo yokuqeda ngokuphelele le nkinga ohlelweni lokukhiqiza. Ngakho-ke, onjiniyela kufanele bagxile ekukhipheni ama-burrs ezigabeni zakamuva ukuze baqinisekise ukuthi umkhiqizo uhlangabezana nezidingo zedizayini. Izindlela nemishini ehlukahlukene iyatholakala yokukhipha ama-burrs emikhiqizweni eyahlukene.
Ngokuvamile, izindlela zokususa ama-burrs zingahlukaniswa ngezigaba ezine:
1. Ibanga elimahhadla (ukuxhumana kanzima)
Lesi sigaba sihlanganisa ukusika, ukugaya, ukugcwalisa, nokukhuhla.
2. Ibanga elijwayelekile (othintana naye othambile)
Lesi sigaba sihlanganisa ukugaya amabhande, ukugoqa, ukugaya okunwebekayo, ukugaya amasondo, nokupholisha.
3. Ibanga lokunemba (oxhumana naye oguquguqukayo)
Lesi sigaba sihlanganisa ukuhlanza, ukucutshungulwa kwe-electrochemical, ukugaya i-electrolytic, kanye nokugingqa.
4. Ibanga lokunemba kakhulu (okunemba othintana naye)
Lesi sigaba sihlanganisa izindlela ezihlukahlukene zokususa, ezifana nokugeleza kwe-abrasive deburring, ukuchithwa kokugaya kazibuthe, i-electrolytic deburring, i-thermal deburring, ne-radium eminyene ene-ultrasonic deburring. Lezi zindlela zingafinyelela ukunemba kokucubungula okuyingxenye ephezulu.
Lapho ukhetha indlela yokukhipha, kubalulekile ukucabangela izici ezihlukahlukene, okuhlanganisa izakhiwo ezibonakalayo zezingxenye, ukwakheka kwazo, usayizi, nokunemba, futhi ukunaka ngokukhethekile izinguquko ezimahhadlahhadla, ukubekezelelana kobukhulu, ukuguquguquka, kanye nensalela. ukucindezeleka.
I-Electrolytic deburring indlela yamakhemikhali esetshenziswa ukususa ama-burrs ezingxenyeni zensimbi ngemva komshini, ukugaya, noma ukugxiviza. Ingakwazi futhi ukuzungeza noma ukucwilisa imiphetho ebukhali yezingxenye. NgesiNgisi, le ndlela ibizwa nge-ECD, okusho ukuthi i-Electrolytic Capacitive Discharge. Ngesikhathi senqubo, i-cathode yamathuluzi (evame ukwenziwa ngethusi) ibekwe eduze nengxenye eshisiwe ye-workpiece enegebe elivame u-0.3-1 mm phakathi kwabo. Ingxenye ye-conductive ye-cathode yethuluzi iqondaniswe nonqenqema lwe-burr, futhi ezinye izindawo zimbozwe ngesendlalelo sokuvikela ukugxilisa isenzo se-electrolytic ku-burr.
