Indlela yokunciphisa ukuphuma kwesixhobo kwiCNCukugalela?
Impazamo ebangelwa ukukhutshwa kwe-radial yesixhobo ichaphazela ngokuthe ngqo ubuncinci bokubunjwa kwempazamo kunye nokuchaneka kwemilo yejometri yomgangatho owenziwe ngomatshini onokuthi uphunyezwe ngesixhobo somatshini phantsi kweemeko ezifanelekileyo zokucubungula. Inkulu i-radial runout yesixhobo, kokukhona ukungazinzi kwemeko yokucubungula isixhobo, kwaye kuchaphazela ngakumbi umphumo wokucubungula.
▌ Izinto ezibangela ukuphuma kweradial
1. Impembelelo ye-radial runout ye-spindle ngokwayo
Ezona zizathu ziphambili zempazamo yokubaleka kweradial ye-spindle yimpazamo ye-coaxiality yejenali nganye yokusonta, iimpazamo ezahlukeneyo zokuthwala ngokwayo, impazamo ye-coaxiality phakathi kweebheringi, ukuphambukiswa kokuphotha, njl. njl., kunye nefuthe labo ekuchanekeni kokujikeleza kweradial i-spindle iyahluka kunye nendlela yokucubungula.
2. Impembelelo yokungahambelani phakathi kweziko lesixhobo kunye neziko lokujikeleza kwe-spindle
Xa isixhobo sifakwe kwi-spindle, ukuba umbindi wesixhobo kunye neziko lokujikeleza le-spindle alihambelani, ukuphuma kwe-radial kwesixhobo kuya kwenzeka ngokuqinisekileyo.
Imiba ethile enempembelelo yile: ukuhambelana kwesixhobo kunye ne-chuck, ingaba indlela yokulayisha isixhobo ichanekile, kunye nomgangatho wesixhobo ngokwaso.
3. Impembelelo yeteknoloji ethile yokucubungula
Ukukhutshwa kwe-radial kwesixhobo ngexesha lokucubungula ikakhulu ngenxa yokuba amandla okusika i-radial ayenza ibe mandundu ukuphuma kwe-radial. Amandla okusika i-radial yinxalenye ye-radial yamandla okusika ngokupheleleyo. Iza kubangela ukuba i-workpiece igobe kwaye iguqule kwaye ivelise ukungcangcazela ngexesha lokucubungula, kwaye iyona nto iphambili yamandla echaphazela umgangatho womsebenzi wokusebenza. Ichatshazelwa kakhulu zizinto ezifana nesixa sokusika, isixhobo kunye nezinto zokusebenza, ijometri yesixhobo, indlela yokuthambisa kunye nendlela yokucubungula.
▌ Iindlela zokunciphisa ukuphuma kweradial
Ukukhutshwa kwe-radial kwesixhobo ngexesha lokucubungula ikakhulu ngenxa yokuba amandla okusika i-radial ayenza ibe mandundu ukuphuma kwe-radial. Ngoko ke, ukunciphisa amandla okusika i-radial ngumgaqo obalulekileyo wokunciphisa ukuphuma kwe-radial. Ezi ndlela zilandelayo zingasetyenziswa ukunciphisa ukuphuma kweradial:
1. Sebenzisa izixhobo ezibukhali
Khetha i-engile yesixhobo esikhudlwana ukwenza isixhobo sibukhali ukunciphisa amandla okusika kunye nokungcangcazela.
Khetha i-engile enkulu ngasemva yesixhobo ukunciphisa ukruthakruthwano phakathi kobuso obungasemva besixhobo kunye ne-elastic recovery layer of the transition surface of the workpiece, ngaloo ndlela unciphisa ukungcangcazela. Nangona kunjalo, i-angle ye-rake kunye ne-angle engasemva yesixhobo ayinakunyulwa ibe nkulu kakhulu, kungenjalo iya kukhokelela kumandla angonelanga kunye nendawo yokuchitha ubushushu yesixhobo.
Inokuba yincinci ngexesha lokucubungula, kodwa ekusebenzeni kakuhle, ukuze kuncitshiswe ukuphuma kwe-radial yesixhobo, kufuneka ibe nkulu ukwenza isixhobo sibukhali.
2. Sebenzisa izixhobo ezomeleleyo
Okokuqala, ububanzi bebha yesixhobo bunokwandiswa. Ngaphantsi kwamandla afanayo okusika i-radial, i-diameter ye-bar tool inyuka nge-20%, kwaye ukuphuma kwe-radial kwesixhobo kunokunciphisa ngama-50%.
Okwesibini, ubude bokwandiswa kwesixhobo bunokuncitshiswa. Ubukhulu bobude besixhobo, ngakumbi ukuguqulwa kwesixhobo ngexesha lokucubungula. Isixhobo sihlala sitshintshile ngexesha lokucubungula, kwaye ukuphuma kwe-radial kwesixhobo kuya kutshintsha ngokuqhubekayo, okubangelwa indawo engalinganiyo ye-workpiece. Ngokufanayo, ukuba ubude bokwandiswa kwesixhobo buncitshiswe nge-20%, ukuphuma kwe-radial kwesixhobo kuya kuncitshiswa nge-50%.
3. Umda wangaphambili wokusika isixhobo kufuneka ube lula
Ngexesha lokucutshungulwa, umphetho ogudileyo wokusika unokunciphisa ukungqubana kweetshiphusi kwisixhobo, kwaye unokunciphisa amandla okusika kwisixhobo, ngaloo ndlela unciphisa ukuphuma kweradial kwesixhobo.
4. Coca i-spindle taper kunye ne-chuck
I-spindle taper kunye ne-chuck kufuneka icoceke, kwaye akufuneki kubekho uthuli kunye nobutyobo obuveliswa ngexesha lokusetyenzwa kwe-workpiece.
Xa ukhetha isixhobo sokulungisa, zama ukusebenzisa isixhobo esinobude obufutshane bokwandisa. Xa usika, amandla kufuneka abe nengqiqo kwaye afane, angabi mkhulu kakhulu okanye amancinci.
5. Ukukhetha okunengqiqo kobunzulu bokusika
Ukuba ubunzulu bokusika buncinci kakhulu, i-machining iya kutyibilika, eya kubangela ukuba isixhobo sitshintshe ngokuqhubekayo i-radial runout ngexesha lomatshini, okwenza umphezulu womatshini ube rhabaxa. Xa ubunzulu bokusika bukhulu kakhulu, amandla okusika aya kwanda ngokufanelekileyo, okubangela ukuguqulwa kwesixhobo esikhulu. Ukwandisa ukuphuma kwe-radial yesixhobo ngexesha lomatshini kuya kwenza ukuba umphezulu womatshini ube rhabaxa.
6. Sebenzisa i-reverse milling ngexesha lokugqiba
Ngexesha lokusila phambili, indawo yesithuba phakathi kwesikrufu sokukhokela kunye notshintsho lwe-nut, oluya kubangela ukondla okungalinganiyo kwe-worktable, okubangela impembelelo kunye nokungcangcazela, okuchaphazela ubomi besixhobo somatshini kunye nesixhobo kunye noburhabaxa bomphezulu womatshini womsebenzi.
Xa usebenzisa i-reverse milling, ubukhulu bokusika buguquka ukusuka kwincinci ukuya enkulu, umthwalo wesixhobo uphinde utshintshe ukusuka kwincinci ukuya enkulu, kwaye isixhobo sizinzile ngakumbi ngexesha lokucoca. Qaphela ukuba oku kusetyenziswa kuphela ngexesha lokugqiba. Kumatshini orhabaxa, ukugaya phambili kusafanele kusetyenziswe kuba ukugaya phambili kunemveliso ephezulu kwaye ubomi besixhobo bunokuqinisekiswa.
7. Ukusetyenziswa ngokufanelekileyo kolwelo lokusika
Ukusetyenziswa ngokufanelekileyo kwe-cut fluid Isisombululo se-Aqueous kunye nokupholisa njengoko umsebenzi oyintloko unempembelelo encinci kumandla okusika. Ioli yokusika, eyona nto isebenzayo njenge-lubricant, inokunciphisa kakhulu amandla okusika.
Ukuziqhelanisa kuye kwafakazela ukuba nje ukuba ukuveliswa kunye nokuchaneka kwendibano yecandelo ngalinye lesixhobo somatshini kuqinisekisiwe kwaye iinkqubo ezifanelekileyo kunye nezixhobo zikhethiweyo, impembelelo ye-radial runout yesixhobo ekuchanekeni kwe-machining ye-workpiece ingancitshiswa.
