MuCNC yekucheka maitiro, pane zvikonzero zvakawanda zvekukanganisa.Iko kukanganisa kunokonzerwa nechishandiso radial runout ndechimwe chezvinhu zvakakosha, izvo zvinokanganisa zvakananga chimiro uye pamusoro peiyo muchina chishandiso chinogona kuwana pasi pemamiriro akanaka.Mukucheka, inokanganisa kurongeka, hutsinye, kusaenzana kwekupfeka kwemidziyo uye hunhu hwematurusi emazino mazhinji.Iyo yakakura iyo radial runout yechishandiso, iyo inonyanya kusagadzikana mamiriro emuchina wechishandiso, uye zvakanyanya kupesvedzera chigadzirwa.
Zvikonzero zveRadial Runout
Kugadzira uye kusungirira kukanganisa kwechishandiso uye spindle zvinhu zvinokonzeresa kudonha uye eccentricity pakati pechishandiso axis uye yakanakira kutenderera axis ye spindle, pamwe neiyo chaiyo yekugadzirisa tekinoroji uye chishandiso, izvo zvinogona kukonzera radial kupera kweCNC milling muchina chishandiso panguva. processing.
1. Kufurira kweradial runout ye spindle
Zvikonzero zvikuru zveiyo radial runout kukanganisa kweiyo spindle ndeye coaxiality, kutakura kwayo, coaxiality pakati pemabheya, kutsauka kweiyo spindle, nezvimwe, pesvedzero paradial kutenderera kushivirira kwe spindle inosiyana nenzira dzakasiyana dzekugadzirisa.Zvinhu izvi zvinoumbwa mukugadzira uye kuunganidza chishandiso chemuchina, uye zvakaoma kuti anoshanda nemuchina wemuchina adzivise simba ravo.
2. Kusiyana kwekusagadzikana pakati pechishandiso chepakati uye spindle rotation centre
Kana chishandiso chaiswa pachirungiso, kana pakati pechishandiso chisingaenderane neizvozvo, chishandiso chinozokonzeresa radial runout.Izvo zvinokonzeresa zvinokonzeresa ndezvi: kukwana kwechishandiso uye chuck, nzira yekurodha chishandiso uye kunaka kwechishandiso pachacho.
3. Mhedzisiro yehunyanzvi hwekugadzira tekinoroji
Chii chakakonzera kubuda kweradial ndeyesimba.Iyo radial yekucheka simba ndeye radial zvigadzirwa zveiyo yakazara kutema simba.Ichaita kuti workpiece ikotame uye iparadze uye ibudise vibration mukuita.Iyo inonyanya kukonzerwa nezvinhu zvakaita sekucheka huwandu, chishandiso uye chidimbu chebasa, nzira yekuzora, chishandiso geometric angle uye nzira yekugadzirisa.
Nzira dzekuderedza Radial Runout
Sezvataurwa muchikamu chechitatu.Kuderedza simba rekucheka radial ndiyo nheyo inokosha yekuideredza.Nzira dzinotevera dzinogona kushandiswa kuderedza
1. Shandisa chinopinza chekucheka chishandiso
Sarudza hombe chekushandisa rake angle kuita kuti chishandiso chirodze kuderedza simba rekucheka uye kudedera.Sarudza yakakura yekubvisa angle yechishandiso kudzikisa kukweshera pakati peiyo huru yekubvisa pamusoro pechishandiso uye elastic yekudzoreredza layer yenzvimbo yekushandura yeworkpiece, nekudaro kuderedza vibration.Nekudaro, iyo rake angle uye clearance angle yechishandiso haigone kusarudzwa yakakura zvakanyanya, zvikasadaro simba uye kupisa kupisa nzvimbo yechishandiso haina kukwana.Naizvozvo, zvinodikanwa kusarudza akasiyana rake angles uye clearance angles yechishandiso zvinoenderana nemamiriro chaiwo.Iyo rough machining inogona kuve idiki, asi mukupedzisa machining, uchifunga kuti kuderedza radial runout yechishandiso, inofanira kunge yakakura kuita kuti chishandiso chiwedzere.
2. Shandisa midziyo yakasimba yekucheka
Iko kune kunyanya nzira mbiri dzekuwedzera simba rekucheka chombo.Imwe ndeyekuwedzera dhayamita yemubati.Pasi pesimba rimwechete rekucheka radial, dhayamita yemubati wemidziyo inowedzera ne20%, uye radial runout yechishandiso inogona kuderedzwa ne50%.Chechipiri ndechekuderedza kureba kwakabuda kwechigadzirwa chekucheka.Iyo yakakura kureba kwekubuda kwechishandiso, iyo yakakura deformation yechishandiso panguva yekugadzirisa.Kana kugadzirisa kuri kuramba kuchichinja, kunoramba kuchichinja, zvichikonzera kuburitsa rough workpiece.Saizvozvo, kureba kwechishandiso kunoderedzwa ne20%, kuchaderedzwawo ne50%.
3. Chiso cherake chechishandiso chinofanira kunge chakatsetseka
Munguva yekugadzira, iyo yakatsetseka reki kumeso inogona kuderedza kukweshera kwediki kuchekwa pachishandiso, uye zvakare inogona kuderedza simba rekucheka pachishandiso, nekudaro ichidzikisa radial runout yechishandiso.
4. Spindle taper gomba uye chuck kuchenesa
Iyo spindle taper gomba uye chuck yakachena, uye hapafanirwe kuve neguruva nemarara anogadzirwa mukugadzirisa.Paunenge uchisarudza chigadziro chekugadzira, edza kushandisa chimbo chine hurefu hupfupi hwekuwedzera kuti utakure, uye simba rinofanira kuva rinonzwisisika uye kunyange, risina kunyanya kukura kana kuduku.
5. Sarudza kubatanidzwa kunonzwisisika kwekucheka
Kana kubatanidzwa kwekucheka kwekucheka kwakanyanya kuduku, chiitiko chekugadzira machining slippage chichaitika, icho chichaita kuti kuenderera mberi kwekuchinja kweradial runout yechishandiso panguva yekugadzira, zvichiita kuti chiso chakaoma.Kana kubatanidzwa kwekucheka kwekucheka kwakanyanya, simba rekushandisa rinowedzera.Ichakonzera deformation yakakura yechishandiso uye mhedzisiro senge iri pamusoro.
6. Shandisa milling pakupedzisa
Sezvo nzvimbo yepakati pakati peiyo lead screw uye nati ichichinja panguva yekugaya pasi, zvinokonzeresa kusaenzana kwekudya kwetabhenakeri, zvichikonzera kuvhunduka uye kudedera, zvichikanganisa hupenyu hwemuchina uye chishandiso uye kushata kwepamusoro kweiyo workpiece.Kana uchikwira-milling, kutema kwekucheka uye mutoro wechishandiso chinoshandukawo kubva kudiki kusvika kuhombe, kuitira kuti chigadziro chacho chiwedzere kugadzikana panguva yekugadzirisa.Ziva kuti izvi zvinongo shandiswa kupedzisa, uye kugaya pasi kuchiri kushandiswa kana roughing.Izvi zvinodaro nekuti kugadzirwa kwekudzikisa milling kwakakwira uye hupenyu hwesevhisi hwechishandiso hunogona kuvimbiswa.
7. Zvinonzwisisika kushandiswa kwekucheka mvura
Kushandisa mvura zvine mutsindo, kunyanya inotonhodza mvura yemushonga, haina zvazvinoita pakucheka simba.Mafuta ekucheka ayo basa guru rekuzora rinogona kuderedza zvakanyanya simba rekucheka.Nekuda kwekuita kwayo kwekuzora, inogona kuderedza kupokana pakati pechishandiso cherake kumeso uye chip uye pakati pechiso cheflank uye neshanduko pamusoro peiyo workpiece, nekudaro ichidzikisa radial runout.Kudzidzira kwakaratidza kuti chero kurongeka kwekugadzira uye kusangana kwechikamu chimwe nechimwe chemuchina kuchichengetedzwa, uye nzira inonzwisisika uye chishandiso chakasarudzwa, pesvedzero yeradial runout yechishandiso pane machining kushivirira kweiyo workpiece inogona kuva. minimized.
