Momwe mungachepetsere kutha kwa zidaCNCmphero?
Cholakwika chomwe chimayambitsidwa ndi kutuluka kwa radial kwa chidacho kumakhudza mwachindunji cholakwika chochepa cha mawonekedwe ndi kulondola kwa mawonekedwe a geometric pamtunda wopangidwa ndi makina omwe angapezeke ndi chida cha makina pansi pamikhalidwe yabwino yopangira. Kuchuluka kwa ma radial kuthamangitsidwa kwa chidacho, kumapangitsa kuti chipangizocho chisasunthike, komanso momwe chimakhudzira momwe chimagwirira ntchito.
▌ Zomwe zimayambitsa kutha kwa ma radial
1. Zotsatira za kutuluka kwa radial kwa spindle yokha
Zifukwa zazikulu za kulakwitsa kwa ma radial runout kwa spindle ndi zolakwika za coaxiality za magazini iliyonse ya spindle, zolakwika zosiyanasiyana zamtundu womwewo, cholakwika cha coaxiality pakati pa ma bearings, kupotoza kwa spindle, ndi zina zambiri, ndi kukopa kwawo pakulondola kwa kuzungulira kwa ma radial. spindle imasiyanasiyana ndi njira yopangira.
2. Zotsatira za kusagwirizana pakati pa chida chogwiritsira ntchito ndi malo ozungulira spindle
Chidacho chikayikidwa pa spindle, ngati pakati pa chida ndi malo ozungulira a spindle ndi osagwirizana, kutuluka kwa radial kwa chidacho kudzachitika mosalephera.
Zomwe zimakhudzidwa ndi izi: kufananiza kwa chida ndi chuck, kaya njira yotsitsa chida ndiyolondola, komanso mtundu wa chida chokha.
3. Zotsatira za luso lapadera la processing
Kuthamanga kwa ma radial kwa chida pakukonza kumachitika makamaka chifukwa mphamvu yodulira ma radial imakulitsa kuthamanga kwa radial. Mphamvu yodulira ma radial ndi gawo la radial la mphamvu yonse yodula. Zidzachititsa workpiece kupinda ndi kupunduka ndi kutulutsa kugwedera pa processing, ndi waukulu chigawo mphamvu zimene zimakhudza khalidwe la workpiece processing. Zimakhudzidwa makamaka ndi zinthu monga kudula kuchuluka, chida ndi zida zogwirira ntchito, zida za geometry, njira yothira mafuta ndi njira yopangira.
▌ Njira zochepetsera kuthamanga kwa radial
Kuthamanga kwa ma radial kwa chida pakukonza kumachitika makamaka chifukwa mphamvu yodulira ma radial imakulitsa kuthamanga kwa radial. Choncho, kuchepetsa mphamvu yodulira ma radial ndi mfundo yofunika kwambiri kuti muchepetse kuthamanga kwa ma radial. Njira zotsatirazi zitha kugwiritsidwa ntchito kuchepetsa kuthamanga kwa ma radial:
1. Gwiritsani ntchito zida zakuthwa
Sankhani chida chokulirapo kuti chidacho chikhale chakuthwa kuti muchepetse mphamvu yodulira komanso kugwedezeka.
Sankhani chokulirapo chida kumbuyo ngodya kuchepetsa kukangana pakati pa nkhope yaikulu kumbuyo kwa chida ndi zotanuka kuchira wosanjikiza wa kusintha padziko workpiece, potero kuchepetsa kugwedera. Komabe, ngodya yakumbuyo ndi mbali yakumbuyo ya chida sichingasankhidwe kukhala yayikulu kwambiri, apo ayi zipangitsa kuti pakhale mphamvu zosakwanira komanso kutentha kwa chipangizocho.
Zitha kukhala zazing'ono panthawi yopangira zovuta, koma pokonza bwino, kuti muchepetse kutuluka kwa radial kwa chidacho, chiyenera kukhala chachikulu kuti chidacho chikhale chokhwima.
2. Gwiritsani ntchito zida zolimba
Choyamba, m'mimba mwake wa chida akhoza ziwonjezeke. Pansi pa mphamvu yomweyo yodulira ma radial, m'mimba mwake chida chimawonjezeka ndi 20%, ndipo kutha kwa chida kumatha kuchepetsedwa ndi 50%.
Chachiwiri, kutalika kwa chidacho kumatha kuchepetsedwa. Kukula kwa kutalika kwa chida, kumapangitsanso kusinthika kwa chida pakukonza. Chidacho chikusintha nthawi zonse pokonza, ndipo kutuluka kwa radial kwa chipangizocho kudzasintha mosalekeza, zomwe zimapangitsa kuti pakhale malo osagwirizana a workpiece. Momwemonso, ngati kutalika kwa chida kumachepetsedwa ndi 20%, kutuluka kwa radial kwa chida kudzachepetsedwanso ndi 50%.
3. Mphepete ya kutsogolo kwa chida iyenera kukhala yosalala
Panthawi yokonza, kutsogolo kosalala kungathe kuchepetsa kukangana kwa tchipisi pa chida, komanso kuchepetsa mphamvu yodula pa chida, potero kuchepetsa kutuluka kwa radial kwa chida.
4. Tsukani taper ya spindle ndi chuck
Chophimba chozungulira ndi chuck chiyenera kukhala choyera, ndipo pasakhale fumbi ndi zinyalala zomwe zimapangidwira panthawi ya ntchito.
Posankha chida chokonzekera, yesani kugwiritsa ntchito chida chokhala ndi kutalika kwaufupi. Podula, mphamvuyo iyenera kukhala yololera komanso yofanana, osati yayikulu kapena yaying'ono.
5. Kusankhidwa koyenera kwa kudula kuya
Ngati kuya kwa kudula kuli kochepa kwambiri, makinawo amatha kutsetsereka, zomwe zimapangitsa kuti chidacho chizisintha mosalekeza kutulutsa kwa radial panthawi yokonza, ndikupangitsa kuti makinawo azikhala ovuta. Pamene kuya kwa kudula kuli kwakukulu, mphamvu yodula idzawonjezeka molingana, zomwe zimapangitsa kuti pakhale chida chachikulu. Kuchulukitsa kutuluka kwa ma radial kwa chida pakumakina kumapangitsanso kuti makina opangidwa ndi makina azikhala ovuta.
6. Gwiritsani ntchito mphero reverse pomaliza
Pa mphero patsogolo, kusiyana pakati pa kutsogolera wononga wononga ndi kusintha mtedza, zomwe zidzachititsa m'goli kudyetsa worktable, chifukwa zimakhudza ndi kugwedera, zimakhudza moyo wa chida makina ndi chida ndi Machining pamwamba roughness wa workpiece.
Mukamagwiritsa ntchito mphero yobwereranso, makulidwe odulira amasintha kuchokera ku zazing'ono kupita zazikulu, katundu wa chida amasinthanso kuchokera ku zazing'ono kupita zazikulu, ndipo chidacho chimakhala chokhazikika panthawi yokonza. Dziwani kuti izi zimagwiritsidwa ntchito pomaliza. Pamakina ovuta, mphero yakutsogolo iyenerabe kugwiritsidwa ntchito chifukwa mphero yamtsogolo imakhala ndi zokolola zambiri ndipo moyo wa chida ungakhale wotsimikizika.
7. Kugwiritsa ntchito moyenera madzi odula
Kugwiritsa ntchito moyenera madzimadzi odulira Madzi amadzimadzi okhala ndi kuziziritsa popeza ntchito yayikulu imakhala ndi mphamvu zochepa pakudulira. Kudula mafuta, omwe makamaka amakhala ngati mafuta, amatha kuchepetsa kwambiri mphamvu yodulira.
Zochita zatsimikizira kuti malinga ngati kupanga ndi kusonkhanitsa kulondola kwa gawo lililonse la chida cha makina kumatsimikiziridwa ndipo njira zomveka ndi zida zimasankhidwa, zotsatira za kutuluka kwa ma radial kwa chida pa makina olondola a workpiece akhoza kuchepetsedwa.
