Iingxaki zoMgangatho woMachining weCNC Ukuguqula iiNdawo

Kwiileyile eziqhelekileyo, iileyile ze-CNC zineemfuno eziphezulu kunye nemigangatho yokucubungula ukuchaneka nokusebenza kakuhle.Ke ngoko, kufuneka ziphuculwe ngetekhnoloji echaneke ngakumbi ukuze zihambelane ngokupheleleyo nezikhokelo zetekhnoloji yokucubungula yanamhlanje.Ukusetyenzwa kweCNC ukuguqula iindawo, kuyimfuneko ukuqinisekisa ukuphunyezwa ngokuzinzile kunye nokuqulunqwa kweteknoloji yenkqubo yokulandelela ngesiseko sokuqinisekisa umgangatho.Inkqubo yonke idinga ukwamkela imo kunye neskimu solawulo oluhle, ukuhlalutya nokuxoxa ngeengxaki zengingqi, kunye nokuphakamisa imigaqo-nkqubo ehambelanayo kunye nemilinganiselo yesi siseko ukuqinisekisa ukuba umgangatho wokucubungula kunye nobuchwepheshe be-CNC yokuguqula iinxalenye zihlangabezana nemigangatho, iya kubeka. isiseko esiluqilima senkqubo yaseTshayina yophuculo.

 1. Ukunyanzeliswa kwe-Vibration ye-CNC Turning Parts

Yitekhnoloji ephambili yokucinezela ukungcangcazela kwinkqubo ye-NC yokujika iinxalenye.Okwangoku, xa kuthelekiswa nezixhobo zoomatshini zemveli zolawulo oluzenzekelayo lwe-CNC yokujika iinxalenye e-China, izixhobo zoomatshini zemveli zenze inkqubela phambili enkulu ekulawuleni lula, kwaye zinokunciphisa ubunzulu bomsebenzi wezandla ukuya kumlinganiselo omkhulu, ngokubanzi ukuphucula ukusebenza kakuhle komsebenzi, ngoko banendima efanelekileyo.Ngakolunye uhlangothi, ngokusetyenziswa kobuchwepheshe obutsha be-CNC yokuguqula iindawo, xa kuthelekiswa neentlobo eziqhelekileyo zezixhobo zoomatshini, ukuchaneka komatshini kunye nomgangatho wenze inkqubela enkulu.Nangona kunjalo, ngokombono wokuziqhelanisa, iinxalenye zokuguqula i-CNC ziluhlobo lolawulo oluzenzekelayo, kwaye imisebenzi yabo yokucubungula kunye nokuphunyezwa kwezicwangciso zobugcisa zifuna inani elikhulu leprogram yangaphambili yokusebenza.Ke ngoko, xa kuthelekiswa neentlobo zesiqhelo zezixhobo zoomatshini, kukho umahluko omkhulu wokuguquguquka.Ke ngoko, ukuze sinike umdlalo opheleleyo kwiingenelo zobugcisa ezifanelekileyo ze-CNC yokuguqula iinxalenye ngokwenyani, kufuneka kwakhona senze uphando oluneenkcukacha malunga namacandelo asebenzayo, senze uhlalutyo oluchanekileyo lweenkqubo ezahlukeneyo kunye nobuchwepheshe, kwaye sifezekise ukuqonda okubanzi kunye neenkcukacha. yemeko yecandelo ngalinye, ukuze kufunyanwe isisombululo senzululwazi kunye nesifanelekileyo esisekelwe koku.Ke ngoko, kwixesha elizayo i-CNC yokuguqula itekhnoloji yokuguqula itekhnoloji, kufuneka sinikele ingqalelo ngakumbi kwisishwankathelo kunye nokuqaliswa kokusebenza, kwaye senze uhlalutyo oluqhelekileyo lweengxaki eziqhelekileyo kwinkqubo yokucubungula, ukuze sibe nembono ekujoliswe kuyo kwaye sibeke ngokwenene. phambili izisombululo ezifanelekileyo.

Kwinkqubo yokusetyenzwa kweendawo zentsimbi, uqhagamshelwano phakathi kwamacandelo omsebenzi kunye neepropu ngokuqinisekileyo ziya kukhokelela ekungcangcazeleni.Isizathu esisisiseko kukuba kwinkqubo yobugcisa bomatshini obufana nokusika, kuya kubakho utshintsho lwexesha, kwaye emva koko kuya kubakho ukungcangcazela, kwaye kuya kubakho into yokuba i-vibration ayinciphisi.Ukongeza, kwinkqubo ye-NC yokuguqula iinxalenye, ukuba ukungcangcazela okugqithisileyo kwenzeka, umphezulu uya konakaliswa, ochaphazela kakhulu umgangatho wokwenziwa komsebenzi, kwaye unempembelelo enkulu kwizixhobo ezisetyenziselwa ukucubungula okuhambelanayo.Ukuba ulawulo alulunganga, ubomi besixhobo buya kuncitshiswa.Ngoko ke, le miqathango ingentla kufuneka ilawulwe ngokungqongqo.

Ukulungiswa kweeparamitha zokusika

Isizukulwana se-self-excited vibration kwinkqubo ye-workpiece machining ihambelana ngokuthe ngqo kwi-frequency yendalo ye-workpiece.Ukuba i-gap phakathi kwesantya esijikelezayo se-workpiece kunye ne-frequency yendalo ye-workpiece yongezwa ngexesha lokusika, kuya kuba nefuthe elicacileyo ekunciphiseni ukunyakaza okuzithandayo kwinkqubo yokusika.Gcina iiparamitha zingatshintshanga.Xa isantya se-workpiece siyi-1000r / min, umgangatho wokucubungula we-workpiece surface yeyona nto inqabileyo.Ukuba isantya sandiswa nje, umgangatho wokucubungula uya kuphucula, kodwa ukwanda kwesantya kunqunyelwe sisixhobo somatshini.Ukongezelela, ukunyuka kwesantya esijikelezayo kuya kwandisa impembelelo kwisixhobo sokugqoka, okuya kunciphisa ubomi benkonzo yesixhobo.Xa isantya somsebenzi sincitshiswa ukuya kwi-60r / min, umgangatho ophezulu we-workpiece uhlangabezana neemfuno.Ingabonwa ukuba ingxaki yokunyakaza okuzichukumisayo inokunyanzeliswa ngokufanelekileyo ngokulungelelanisa ngokufanelekileyo isantya somsebenzi kwiiparamitha zokusika.

Ukudambisa kwandisa indlela yokumanzisa

Ngokuqwalasela kunye nohlalutyo lwenkqubo yamacandelo omatshini, sifumene ukuba iindawo ngokwazo zingumthombo wokungcangcazela okuzithandayo ngexesha lenkqubo yokusika, okubangelwa iindonga zabo ezincinci.Ngophando lovavanyo, indlela esebenzayo yokusombulula ingxaki kukunyusa ukuthambisa ukufezekisa injongo yokunciphisa ukungcangcazela.

 

 2. Iingxaki ezinxulumene ne-CNC Turning Parts

Ngokutsho kolu phando lungentla oluneenkcukacha malunga neengxaki ezinxulumene ne-CNC yokuguqula iinxalenye kwinkqubo yangoku yokuhamba kweenkqubo ezihambelanayo kunye nobuchwepheshe e-China, kunye namanyathelo kunye nezicwangciso zokunciphisa i-vibration, sinokuba nolawulo olubanzi kwiingxaki ezininzi ezifuna kunikwe ingqwalasela ngexesha lenkqubo yomsebenzi kunye namacandelo afuna ukuqiniswa kunye nokuphuculwa.Kule zilandelayo, iingxaki eziphambili kunye nezisombululo ezisisiseko kwiingxenye ze-CNC ezijikayo ziya kuhlalutywa, zijolise ekunqumeni imigaqo esisiseko yophuhliso lweteknoloji yexesha elizayo.

Xa usebenzisa imoto yezoqoqosho eqhelekileyo ukuguqulwa kakuhle kweeshafts zoomatshini bezolimo, isixhobo somatshini esifanayo kunye nenkqubo efanayo ye-CNC isetyenziswa, kodwa ubukhulu obuhlukeneyo bezinto zokusebenza ezigqityiweyo zifunyenwe.Kunzima ukulawula impazamo yobungakanani bomsebenzi phakathi komgangatho osemgangathweni, kwaye umgangatho wokucubungula awuzinzanga kakhulu.Ukuze sisombulule le ngxaki, sinokutshintsha inani lamaxesha ukutshintsha isikhundla kabini ukusuka kweyokuqala ukuqinisekisa umgangatho wokucubungula.

Njengoko kuhlalutyiweyo ngasentla, xa kuthelekiswa nezixhobo zoomatshini bemveli, ulawulo oluzenzekelayo lwe-CNC olujikayo lwenze inkqubela phambili enkulu ekulawuleni lula.CNC iinxalenye ezijikayo zezohlobo lolawulo oluzenzekelayo.Umsebenzi womatshini kunye nokuphunyezwa kwesikimu sobugcisa kufuna inani elikhulu leprogram yangaphambili ukuze isebenze.Ukuthetha ngokuthelekisa, ukuqina kwe-tailstock kubuthathaka.Kwinkqubo yokusika, umgama omncinci phakathi kwesixhobo kunye ne-tailstock, ubude obukhulu buya kuba, obuya kwandisa ubungakanani bomsila womsila womsebenzi, ukuvelisa i-taper, kunye nokuchaphazela i-cylindricity ye-workpiece.Ngoko ke, kwinkqubo yokuvelisa i-CNC yokuguqula iinxalenye zokucubungula, akuyimfuneko kuphela ukunikela ingqalelo kunye nokufunda iingxaki ezikhoyo, kodwa kwakhona ukugqiba izisombululo ezisisiseko kunye nezisombululo ezisekelwe kwinyani, ziphathwe ngesimo sengqondo esinzulu, siphucule ngokubanzi Ubunzululwazi kunye nobume obuqhelekileyo be-CNC ekuguquleni iinxalenye zokusetyenzwa, kunye nokuseka imigaqo esisiseko kunye nemikhombandlela yophuhliso lomsebenzi kunye nokulandelela
