Kwinkqubo yokusika i-CNC, kukho izizathu ezininzi zeempazamo.Impazamo ebangelwa yi-radial runout yesixhobo yenye yezinto ezibalulekileyo, ezichaphazela ngokuthe ngqo imilo kunye nomgangatho onokuthi ufikeleleke phantsi kweemeko ezifanelekileyo.Ekusikeni, kuchaphazela ukuchaneka, uburhabaxa, ukungalingani kokunxitywa kwesixhobo kunye neempawu zezixhobo zamazinyo amaninzi.Inkulu i-radial runout yesixhobo, ngakumbi ukungazinzi kwesimo somatshini wesixhobo, kwaye sichaphazela ngakumbi imveliso.
Iimbangela zeRadial Runout
Iimpazamo zokuvelisa kunye nokubambelela kwisixhobo kunye namacandelo e-spindle kubangela ukukhukuliseka kunye nokuchaneka phakathi kwe-axis yesixhobo kunye ne-axis yokujikeleza efanelekileyo ye-spindle, kunye neteknoloji ethile yokucwangcisa kunye nesixhobo, esinokubangela ukuphuma kwe-radial yesixhobo somatshini wokugaya i-CNC ngexesha. ukuqhubekeka.
1. Impembelelo ye-radial runout ye-spindle
Izizathu eziphambili zempazamo ye-radial runout ye-spindle yi-coaxiality, ukuthwala kwayo, ukubambisana phakathi kweebheringi, ukuphambuka kwe-spindle, njl.Ezi zinto zenziwe kwinkqubo yokuvelisa kunye nokudibanisa isixhobo somatshini, kwaye kunzima kumqhubi wesixhobo somatshini ukuphepha impembelelo yabo.
2. Umahluko wokungahambelani phakathi kweziko lesixhobo kunye neziko lokujikeleza kwe-spindle
Xa isixhobo sifakwe kwi-spindle, ukuba umbindi wesixhobo awuhambelani naloo nto, isixhobo siya kubangela ukuba i-radial runout.Izinto ezithile ezichaphazelayo zezi: ukufaneleka kwesixhobo kunye ne-chuck, indlela yokulayisha isixhobo kunye nomgangatho wesixhobo ngokwaso.
3. Impembelelo yeteknoloji ethile yokucubungula
Yintoni ebangele ukuphuma kweradial yiamandla.I-radial cutting force yimveliso ye-radial yamandla okusika ngokupheleleyo.Iya kubangela ukuba i-workpiece igobe kwaye iguqule kwaye ivelise ukungcangcazela kwinkqubo.Ibangelwa ikakhulu zizinto ezifana nesixa sokusika, isixhobo kunye nesixhobo somsebenzi, indlela yokuthambisa, isixhobo se-engile yejometri kunye nendlela yokucubungula.
Iindlela zokunciphisa iRadial Runout
Njengoko kukhankanyiwe kwingongoma yesithathu.Ukunciphisa i-radial cutting force ngumgaqo obalulekileyo wokunciphisa.Ezi ndlela zilandelayo zingasetyenziselwa ukunciphisa
1. Sebenzisa isixhobo sokusika esibukhali
Khetha i-engile yesixhobo esikhulu ukwenza isixhobo sibukhali ukunciphisa amandla okusika kunye nokungcangcazela.Khetha i-angle yokucoca enkulu yesixhobo sokunciphisa ukungqubana phakathi kwendawo ephambili yokucoca isixhobo kunye ne-elastic recovery layer of the transition surface of the workpiece, ngaloo ndlela unciphisa ukungcangcazela.Nangona kunjalo, i-rake angle kunye ne-angle yokucoca isixhobo ayinakunyulwa kakhulu, ngaphandle koko amandla kunye nommandla wokutshatyalaliswa kobushushu besixhobo awanelanga.Ngoko ke, kuyimfuneko ukukhetha ii-angles ze-rake ezahlukeneyo kunye nee-angles zokucoca isixhobo ngokwemeko ethile.I-machining rough inokuba yincinci, kodwa ekugqityweni komatshini, ngokuqwalasela ukunciphisa i-radial runout yesixhobo, kufuneka ibe mkhulu ukwenza isixhobo sibukhali.
2. Sebenzisa izixhobo ezinamandla zokusika
Kukho ikakhulu iindlela ezimbini zokunyusa amandla esixhobo sokusika.Enye kukwandisa ububanzi bomntu.Ngaphantsi kwamandla afanayo okusika i-radial, ububanzi bomnini wesixhobo bunyuka nge-20%, kwaye ukuphuma kwe-radial kwesixhobo kungancitshiswa ngama-50%.Okwesibini kukunciphisa ubude obude besixhobo sokusika.Ubude obude besixhobo, ngakumbi ukuguqulwa kwesixhobo ngexesha lokucubungula.Xa ukucutshungulwa kukutshintsha rhoqo, kuya kuqhubeka nokutshintsha, okukhokelela ekuveliseni i-workpiece erhabaxa.Ngokufanayo, ubude bokwandiswa kwesixhobo buncitshiswa nge-20%, buya kuncitshiswa nge-50%.
3. Iraki yobuso besixhobo kufuneka igudileyo
Ngexesha lokucutshungulwa, ubuso berake obugudileyo bunokunciphisa ukungqubana kokusikwa okuncinci kwisixhobo, kwaye kunokunciphisa amandla okusika kwisixhobo, ngaloo ndlela kuncitshiswe ukuphuma kweradial kwesixhobo.
4. Umngxuma we-spindle taper kunye nokucoca i-chuck
Umngxuma we-spindle taper kunye ne-chuck zicocekile, kwaye akufuneki kubekho uthuli kunye ne-debris eveliswa ekuqhubeni.Xa ukhetha isixhobo somatshini, zama ukusebenzisa isixhobo esinobude obufutshane bokwandisa ukulayisha, kwaye amandla kufuneka abe nengqiqo kwaye angabi nkulu kakhulu okanye amancinci.
5. Khetha ukubandakanyeka okufanelekileyo kwi-cut edge
Ukuba ukubandakanyeka komgca wokusika kuncinci kakhulu, i-phenomenon ye-machining slippage iya kwenzeka, eya kubangela ukuba utshintsho oluqhubekayo lwe-radial runout yesixhobo ngexesha lokucoca, okubangelwa ubuso obunzima.Ukuba ukubandakanyeka komgca wokusika kukhulu kakhulu, amandla esixhobo anyuka.Iya kubangela deformation enkulu isixhobo kunye nesiphumo njengoko ngasentla efanayo.
6. Sebenzisa ukungqusha ekugqibeni
Njengoko indawo umsantsa phakathi screw lead kunye nut utshintsho ngexesha lokusila phantsi, oko kuya kubangela feed engalinganiyo worktable, kubangele ukothuka kunye vibration, echaphazela ubomi umatshini kunye isixhobo kunye noburhabaxa umphezulu workpiece.Xa u-up-milling, ubukhulu bokusika kunye nomthwalo wesixhobo ubuye utshintshe ukusuka kwincinci ukuya enkulu, ukwenzela ukuba isixhobo sizinze ngakumbi ngexesha lokucubungula.Qaphela ukuba oku kusetyenziselwa ukugqiba kuphela, kwaye i-down milling isasetyenziswa xa i-roughing.Oku kungenxa yokuba imveliso ye-down milling iphezulu kwaye ubomi benkonzo yesixhobo bunokuqinisekiswa.
7. Ukusetyenziswa ngokufanelekileyo kolwelo lokusika
Ukusetyenziswa okunengqiqo kolwelo, ikakhulu isisombululo samanzi okupholisa, kunempembelelo encinci kumandla okusika.Ioli yokusika umsebenzi wayo oyintloko wokuthambisa unokunciphisa kakhulu amandla okusika.Ngenxa yesiphumo sayo sokuthambisa, inokunciphisa ingxabano phakathi kobuso beraki yesixhobo kunye netshiphu naphakathi kobuso beflanki kunye nomphezulu wenguqu wesixhobo sokusebenza, ngaloo ndlela inciphisa ukuphuma kweradial.Ukuziqhelanisa kuye kwabonisa ukuba ukuchaneka kokuveliswa kunye nokuhlanganisa inxalenye nganye yomatshini kuqinisekiswa, kwaye inkqubo efanelekileyo kunye nezixhobo zikhethiweyo, impembelelo yokukhutshwa kwe-radial yesixhobo ekunyamezelweni kwe-machining ye-workpiece ingaba. ncitshisiwe.
