Ungakugwema kanjani ukushiswa kokusika ama-workpieces?

I-disc yokusika yenziwe nge-resin njenge-binder, yengezwe nge-glass fiber mesh, futhi ihlanganiswe nezinto ezihlukahlukene.Ukusebenza kwayo kokusika kubaluleke kakhulu kobunzima bokusika izinto ezifana nensimbi yengxubevange nensimbi engagqwali.Izindlela zokusika ezomile nezimanzi zenza ukunemba kokusika kuzinze.Ngesikhathi esifanayo, ukukhethwa kwezinto zokusika nobulukhuni kuthuthukisa ukusika ukusebenza kahle futhi kunciphisa izindleko zokukhiqiza.Kodwa ngesikhathi sokusika, kungase kube nezingozi zokushiswa kwama-workpieces.

Singakugwema kanjani ukushisa ngesikhathi sokusika, okungathinta ukusebenza kahle kokusika kuphansi kakhulu?

1, Ukukhethwa kobulukhuni

Uma ubulukhuni buphezulu kakhulu, isakhiwo se-metallographic sezinto ezibonakalayo sizoshiswa, futhi i-microstructure yezinto ezibonakalayo ayikwazi ukuhlolwa ngokunembile, okuholela kumaphutha;Uma ubulukhuni buphansi kakhulu, kuzoholela ekusebenzeni kahle kokusika futhi kuchithe i-blade yokusika.Ukuze uvimbele ukushiswa nokucijile ngesikhathi sokusika, ukuqina kwempahla kuphela okudingeka kuhlolwe kanye nokusetshenziswa okufanele kwesipholile.

2. Ukukhethwa kwezinto zokusetshenziswa

Impahla ekhethwayo i-aluminium oxide, kanti i-silicon carbide ikhethwa ngokusika izinto ezingezona i-ferrous nezingezona ezensimbi.Ngenxa yokuthi impahla ye-aluminium oxide esetshenziselwa ukusika izinto zensimbi ayisebenzi ngamakhemikhali nezingxenye zamakhemikhali ensimbi, kunenzuzo ekusikeni.Izinsimbi ezingezona ezensimbi nezingezona i-ferrous zinomsebenzi wamakhemikhali ophansi, kuyilapho izinto ze-silicon carbide zinomsebenzi wamakhemikhali ophansi uma kuqhathaniswa ne-alumina, ukusebenza kangcono kokusika, ukusha okuncane, nokuguga okuncane.

3, Ukukhethwa kwembudumbudu

Ukukhetha usayizi wezinhlayiyana omaphakathi kunenzuzo ekusikeni.Uma ubukhali budingeka, usayizi wokusanhlamvu oqinile ungakhethwa;Uma ukusika kudinga ukunemba okuphezulu, i-abrasive enosayizi wezinhlayiyana ezicolekile kufanele kukhethwe.
