Izinto eziluncedo kunye nokusetyenziswa kwamavili okugaya idayimani

Uninzi lwedayimani kwimizi-mveliso isetyenziselwa ukwenza izixhobo ezirhabaxa.Ubunzima bedayimane buphezulu kakhulu, amaxesha ama-2, amaxesha ama-3 kunye namaxesha ama-4 e-boron carbide, i-silicon carbide kunye ne-corundum ngokulandelanayo.Inokusila izinto zokusebenza ezinzima kakhulu kwaye ineenzuzo ezininzi.Ezinye zezicelo zayo kunye neendlela zokunxibaZ-NGONYAMAiya kukubonisa Funda ngakumbi.

Inzuzo

1. Ukusebenza okuphezulu kokusila: Xa kusila i-carbide enesamente, ukusebenza kwayo kakuhle kokugaya kuphindwe kaninzi kune-silicon carbide.Xa ukugaya i-high-speed tool tool kunye nokusebenza kakubi kokugaya, umyinge osebenzayo wanda ngamaxesha angaphezu kwama-5;

2. Ukumelana nokunxiba okuphezulu: Ukumelana nokunxiba kweivili lokusila isamenteiphezulu kakhulu, kwaye ukusetyenziswa kweengqungquthela ze-abrasive kuncinci kakhulu, ngakumbi xa ukugaya i-workpieces enzima kunye ne-brittle workpieces, iinzuzo zizona zibalaseleyo.Xa ugaya intsimbi eqinile ngevili lokusila idayimane, ukuxhathisa kwayo ukunxiba ngamaxesha angama-100-200 ama-abrasives ngokubanzi;xa ugaya i-alloys eqinile, yi-5,000-10,000 amaxesha e-abrasives jikelele;

3. Amandla amancinci okusila kunye nokushisa okuphantsi kokugaya: Ubunzima kunye nokuxhatshazwa kokugqoka kwee-diamond particles abrasive particles ziphezulu kakhulu, iinqununu ezinqabileyo zinokuhlala zibukhali ixesha elide, kwaye kulula ukunqumla kwi-workpiece.Xa kusila i-carbide ngevili lokusila ledayimani enereyini, amandla okusila yi-1/4 ukuya kwi-1/5 kuphela yamandla okusila wevili eliqhelekileyo lokusila.I-thermal conductivity ye-diamond iphezulu kakhulu, i-17.5 amaxesha e-silicon carbide, kunye nokushisa okusikiweyo kuhanjiswa ngokukhawuleza, ngoko ukushisa okusila kuphantsi.Umzekelo, sebenzisa ivili lokugaya i-silicon carbide ukugaya i-carbide enesamente, ubunzulu bokusika yi-0.02mm, ubushushu bokugaya buphezulu njenge-1000 ℃ ~ 1200 ℃, kunye nevili lokusila idayimane eline-resin bond lisetyenziselwa ukugaya.Phantsi kweemeko ezifanayo, indawo yokusila Ubushushu kuphela 400℃;

4. I-workpiece yokugaya inobungqina obuphezulu kunye nomgangatho ophezulu womgangatho: xa ugaya izixhobo ze-carbide kunye namavili okugaya idayimane, ubunzima bobuso be-blade kunye ne-blade buphantsi kakhulu kunoko kunye namavili okugaya i-silicon carbide.Ubukhali kakhulu, ukuqina kwe-blade kunokunyuswa ngamaxesha angama-1 ukuya kuma-3.I-workpiece ecutshungulwayo ngevili lokusila idayimani ngokubanzi inexabiso elirhabaxa lika-Ra 0.1~0.025μm, elinokuphuculwa ngamabakala angama-1 ~ 2 xa kuthelekiswa nokusila kwevili eliqhelekileyo lokusila.

Isicelo

Amavili okugaya idayimanezisetyenziswa ngokubanzi ukugaya izinto ezinobunzima obuphezulu kunye nezinto ezixabisekileyo ekunzima ukuzigaya ngamavili okusila aqhelekileyo kwaye zifuna umgangatho ophezulu.Izinto zokusebenza ezingezizo ezentsimbi ezifana nokugaya kunye nokusika i-carbide ene-cemented, i-ceramics, iglasi, i-agate, amatye anqabileyo, izinto ze-semiconductor, amatye nawo afanelekile kwi-alloys ye-titanium.

Indlela yokunxiba

Ngenxa yobunzima obuphezulu bedayimane kunye nokusebenza kakuhle kokusika, ivili lokugaya ngokubanzi akufuneki ukuba linxibe.Nangona kunjalo, emva kwexesha lokusetyenziswa, ii-chips zivaliwe, ukusebenza kuncitshisiwe, kwaye nokuba amandla okugaya makhulu, ubushushu bokugaya buyanda, kwaye isondo lokugaya liqhekekile.Emva kokuba ivili lokugaya livaliwe, kufuneka linqunywe.Xa unxiba, ivili lokusila idayimani linokulolwa ngesilicon carbide okanye i-corundum whetstone.Indlela yokuqhagamshelana ne-silicon carbide okanye i-oilstone ye-corundum enevili elijikelezayo lokusila idayimani.Ngethuba lenkqubo yokusila, ngenxa yobunzima obuphezulu bevili lokusila idayimane, i-silicon carbide okanye i-oilstone ye-corundum inomhlaba, kwaye i-silicon carbide okanye i-oilstone ye-corundum iyakususa idayimani.Iichips kwivili lokusila zibuyisela ukusebenza kokusika kwevili lokugaya.

Oku ngasentla kumxholo ochaphazelekayo malunga neenzuzo, izicelo kunye neendlela zokugqoka zamavili okugaya idayimane ekwabelwana nawe.Ndiyathemba ukuba ngalo mxholo ungentla, unokuba nokuqonda ngakumbi kunye nokuqonda amavili okusila idayimani.
