Mu CNC kudula ndondomeko, pali zifukwa zambiri zolakwika.Cholakwika choyambitsidwa ndi chida chothamangitsira radial ndi chimodzi mwazinthu zofunika kwambiri, zomwe zimakhudza mwachindunji mawonekedwe ndi pamwamba zomwe chida cha makina chingathe kukwaniritsa pamikhalidwe yabwino.Podula, zimakhudza kulondola, roughness, kusagwirizana kwa kuvala kwa zida ndi makhalidwe a zida za mano ambiri.Kuchuluka kwa ma radial kuthamangitsidwa kwa chidacho, kusakhazikika kwa makina a chipangizocho, komanso kumakhudza kwambiri mankhwalawa.
Zifukwa za Radial Runout
Kupanga ndi kuwongolera zolakwika za chida ndi zida zopota zomwe zimapangitsa kuti pakhale kugwedezeka ndi kukhazikika pakati pa olamulira chida ndi njira yabwino yozungulira ya spindle, komanso ukadaulo waukadaulo ndi zida, zomwe zingayambitse kutha kwa ma radial a CNC mphero chida panthawi. kukonza.
1. Chikoka cha ma radial runout of spindle
Zifukwa zazikulu za kulakwitsa kwa radial runout kwa spindle ndi coaxiality, kubereka kwake, coaxiality pakati pa mayendedwe, kupatuka kwa spindle, etc.Zinthuzi zimapangidwira popanga ndi kusonkhanitsa chida cha makina, ndipo zimakhala zovuta kuti wogwiritsa ntchito makinawo asapewe mphamvu zawo.
2. Kusiyana kwa kusagwirizana pakati pa chida chachitsulo ndi malo ozungulira spindle
Chidacho chikayikidwa pa spindle, ngati pakati pa chidacho sichikugwirizana ndi izo, chidacho chidzachititsa kuti radial iwonongeke.Zomwe zimakhudzidwa kwambiri ndi izi: kukwanira kwa chida ndi chuck, njira yosungira chida ndi ubwino wa chida chokha.
3. Zotsatira za luso lapadera la processing
Chomwe chinayambitsa kutuluka kwa ma radial ndimphamvu.Mphamvu yodulira ma radial ndi zida za radial zamphamvu yonse yodula.Zimapangitsa kuti workpiece ipindike ndikupotoza ndikutulutsa kugwedezeka munjirayo.Zimayambitsidwa makamaka ndi zinthu monga kudula kuchuluka, chida ndi zida zogwirira ntchito, njira yothira mafuta, njira ya geometric ndi njira yopangira.
Njira Zochepetsera Kuthamanga kwa Ma Radial
Monga tanenera pa mfundo yachitatu.Kuchepetsa mphamvu yodulira radial ndi mfundo yofunika kuichepetsa.Njira zotsatirazi zingagwiritsidwe ntchito kuchepetsa
1. Gwiritsani ntchito chida chakuthwa chodulira
Sankhani chida chokulirapo kuti chidacho chikhale chakuthwa kuti muchepetse mphamvu yodulira komanso kugwedezeka.Sankhani lalikulu chilolezo mbali ya chida kuchepetsa kukangana pakati pa waukulu chilolezo pamwamba pa chida ndi zotanuka kuchira wosanjikiza wa kusintha padziko workpiece, potero kuchepetsa kugwedera.Komabe, ngodya ya rake ndi chilolezo cha chida sichingasankhidwe chokulirapo, apo ayi mphamvu ndi kutentha kwa gawo la chida sikukwanira.Chifukwa chake, ndikofunikira kusankha ma angles osiyanasiyana a rake ndi chilolezo cha chida malinga ndi momwe zilili.Makina okhwima amatha kukhala ang'onoang'ono, koma pomaliza, poganizira kuti kuchepetsa kutha kwa chidacho, chiyenera kukhala chachikulu kuti chidacho chikhale chokhwima.
2. Gwiritsani ntchito zida zodulira mwamphamvu
Pali makamaka njira ziwiri zowonjezera mphamvu ya chida chodulira.Chimodzi ndicho kukulitsa mainchesi a chotengera.Pansi pa mphamvu yomweyo yodulira ma radial, kukula kwa chogwiritsira ntchito kumawonjezeka ndi 20%, ndipo kutuluka kwa radial kwa chida kumatha kuchepetsedwa ndi 50%.Chachiwiri ndi kuchepetsa kutalika kwa chida chodulira.Kukula kwakukulu kwa kutalika kwa chida, kumapangitsanso kusinthika kwa chida panthawi yokonza.Pamene processing ikusintha nthawi zonse, idzapitirizabe kusintha, zomwe zimapangitsa kuti ntchito ikhale yovuta.Mofananamo, kutalika kwa chidacho kumachepetsedwa ndi 20%, kudzachepetsedwa ndi 50%.
3. Nkhope ya chipangizocho ikhale yosalala
Pakukonza, nkhope yosalala yosalala imatha kuchepetsa kukangana kwa kadulidwe kakang'ono pa chida, komanso kuchepetsa mphamvu yodulira pachidacho, potero kuchepetsa kutuluka kwa radial kwa chida.
4. Bowo la spindle taper ndikuyeretsa chuck
Bowo la spindle taper ndi chuck ndi zoyera, ndipo sikuyenera kukhala fumbi ndi zinyalala zomwe zimapangidwa pokonza.Posankha chida chopangira makina, yesani kugwiritsa ntchito chida chokhala ndi kutalika kwaufupi kuti mutenge, ndipo mphamvuyo iyenera kukhala yololera komanso ngakhale, osati yaikulu kapena yaying'ono kwambiri.
5. Sankhani chinkhoswe choyenera cha m'mphepete
Ngati kuchitapo kanthu kwa m'mphepete mwachitsulo kumakhala kochepa kwambiri, chodabwitsa cha makina otsetsereka chidzachitika, zomwe zidzapangitse kusintha kosalekeza kwa kutuluka kwa radial kwa chida panthawi ya Machining, zomwe zimapangitsa kuti nkhope ikhale yovuta.Ngati chiwongolero cha m'mphepete mwake ndi chachikulu kwambiri, mphamvu ya chida imakula.Zidzachititsa mapindikidwe lalikulu la chida ndi zotsatira monga pamwamba chomwecho.
6. Gwiritsani ntchito mphero pomaliza
Monga malo kusiyana pakati kutsogolera wononga ndi nati kusintha pa pansi mphero, izo zidzachititsa chakudya chosagwirizana cha worktable, kuchititsa mantha ndi kugwedera, zimakhudza moyo wa makina ndi chida ndi roughness pamwamba pa workpiece.Pamene mmwamba-mphero, makulidwe odula ndi katundu wa chida amasinthanso kuchokera ku zazing'ono mpaka zazikulu, kuti chidacho chikhale chokhazikika panthawi yokonza.Zindikirani kuti izi zimagwiritsidwa ntchito pomaliza, ndipo mphero yotsika ikugwiritsidwabe ntchito pamene roughing.Izi zili choncho chifukwa zokolola za pansi mphero ndizokwera ndipo moyo wautumiki wa chida ukhoza kutsimikiziridwa.
7. Kugwiritsa ntchito moyenera madzi odula
Kugwiritsa ntchito madzimadzi moyenerera, makamaka madzi oziziritsa, sikukhudza mphamvu yodulira.Mafuta odulira omwe ntchito yake yayikulu ndi mafuta amatha kuchepetsa kwambiri mphamvu yodulira.Chifukwa cha mphamvu yake yopangira mafuta, imatha kuchepetsa kukangana pakati pa chida chopangira nkhope ndi chip komanso pakati pa nkhope yakumbali ndi kusintha kwa chogwirira ntchito, potero kuchepetsa kutuluka kwa ma radial.Zochita zatsimikizira kuti malinga ngati kulondola kwa kupanga ndi kusonkhana kwa gawo lililonse la makina kumatsimikiziridwa, ndipo ndondomeko yoyenera ndi zida zimasankhidwa, chikoka cha kutuluka kwa ma radial kwa chida pa kulekerera kwa makina a workpiece kungakhale. kuchepetsedwa.
