Maitiro ekudzikisa chishandiso runout mukatiCNCkugaya?
Iko kukanganisa kunokonzerwa neiyo radial runout yechishandiso inokanganisa zvakananga hushoma chimiro chikanganiso uye geometric chimiro chechokwadi chemichina yepasi iyo inogona kuwanikwa nemuchina chishandiso pasi pemamiriro ekugadzirisa. Iyo yakakura iyo radial runout yechishandiso, iyo inonyanya kusagadzikana mamiriro ekugadzirisa echishandiso, uye zvakanyanya kukanganisa maitiro ekugadzirisa.
▌ Zvinokonzera radial runout
1. Mhedzisiro yeradial runout ye spindle pachayo
Zvikonzero zvikuru zveiyo radial runout kukanganisa kweiyo spindle iko coaxiality kukanganisa kwega yega spindle magazine, zvikanganiso zvakasiyana-siyana zvekutakura pachayo, coaxiality kukanganisa pakati pemabheya, spindle deflection, nezvimwewo, uye simba ravo pakurongeka kweradial rotation. iyo spindle inosiyana nekugadzirisa nzira.
2. Mhedzisiro yekusawirirana pakati pemudziyo wekushandisa uye spindle rotation centre
Kana chishandiso chaiswa pachirukwa, kana pakati pechishandiso uye nzvimbo yekutenderera yespindle isingaenderane, iyo radial runout yechishandiso ichaitika zvisingaite.
Izvo chaizvo zvinofurira zvinhu ndezvi: kuenzanirana kwechishandiso uye chuck, ingave iyo nzira yekurodha yakaringana, uye mhando yechishandiso pachayo.
3. Mhedzisiro yehunyanzvi hwekugadzira tekinoroji
Iyo radial runout yechishandiso panguva yekugadziriswa inonyanya nekuti iyo radial yekucheka simba inowedzera iyo radial runout. Iyo radial yekucheka simba ndiyo radial chikamu cheiyo yakazara kutema simba. Iyo ichaita kuti iyo workpiece ikotame uye igadzirise uye ibudise vibration panguva yekugadzirisa, uye ndiyo huru chikamu simba rinokanganisa kunaka kweiyo workpiece processing. Iyo inonyanya kukanganiswa nezvinhu zvakaita sekucheka huwandu, chishandiso uye workpiece zvinhu, chishandiso geometry, lubrication nzira uye nzira yekugadzirisa.
▌ Nzira dzekudzikisa radial runout
Iyo radial runout yechishandiso panguva yekugadziriswa inonyanya nekuti iyo radial yekucheka simba inowedzera iyo radial runout. Nokudaro, kuderedza simba rekucheka radial ndiyo nheyo inokosha yekuderedza radial runout. Nzira dzinotevera dzinogona kushandiswa kuderedza radial runout:
1. Shandisa zvishandiso zvinopinza
Sarudza hombe chombo reke angle kuita kuti chishandiso chirodze kuderedza simba rekucheka uye kudedera.
Sarudza yakakura chishandiso kumashure kona yekudzikisa kukweshera pakati peiyo huru yekumashure kumeso kwechishandiso uye elastic yekudzoreredza layer yenzvimbo yekushandura yeworkpiece, nekudaro kuderedza vibration. Nekudaro, iyo reki angle uye kumashure kwekona yechishandiso haigone kusarudzwa yakakura zvakanyanya, zvikasadaro zvinozotungamira kune isina kukwana simba uye kupisa kwekupisa nzvimbo yechishandiso.
Inogona kunge iri diki panguva yekuomesera, asi mukugadzirisa kwakanaka, kuitira kuderedza radial runout yechishandiso, inofanira kunge yakakura kuita kuti chishandiso chiwedzere.
2. Shandisa zvishandiso zvakasimba
Kutanga, dhayamita yebhari yekushandisa inogona kuwedzerwa. Pasi pesimba rimwechete rekucheka radial, iyo dhayamita yebhawa inowedzera ne20%, uye radial runout yechishandiso inogona kudzikiswa ne50%.
Chechipiri, kureba kwechishandiso kunogona kuderedzwa. Iyo yakakura yekuwedzera kureba kwechishandiso, iyo yakakura deformation yechishandiso panguva yekugadzirisa. Chishandiso chiri mukuchinja nguva dzose panguva yekugadziriswa, uye iyo radial runout yechishandiso ichachinja ichienderera, zvichikonzera kusaenzana kwechiso chebasa. Saizvozvo, kana kureba kwechishandiso kwakaderedzwa ne20%, radial runout yechishandiso ichaderedzwawo ne50%.
3. Iko kumucheto kwechemberi kwechigadziro kunofanira kuva kwakatsetseka
Munguva yekugadzira, iyo yakatsetseka yekucheka kumucheto inogona kuderedza kukweshera kwemachipisi pachishandiso, uye inogona zvakare kuderedza simba rekucheka pachishandiso, nekudaro ichidzikisa radial runout yechishandiso.
4. Chenesa taper ye spindle uye chuck
Iyo spindle taper uye chuck inofanirwa kuve yakachena, uye hapafanirwe kuve neguruva nemarara anogadzirwa panguva yekugadzira workpiece.
Paunenge uchisarudza chishandiso chekugadzirisa, edza kushandisa chishandiso chine urefu hupfupi hwekuwedzera. Paunenge uchicheka, simba racho rinofanira kuva rinonzwisisika uye rakafanana, kwete rakakura kana kuti duku.
5. Kusarudzwa kunonzwisisika kwekucheka kudzika
Kana iyo yekucheka kudzika kuri kudiki, machining anotsvedza, izvo zvinozoita kuti chishandiso chirambe chichichinja radial runout panguva yekugadzira, ichiita kuti iyo yakashongedzwa nzvimbo yakaoma. Kana iyo yekucheka yakadzika yakakura, simba rekucheka rinowedzera zvinoenderana, zvichikonzera deformation yakakura yekushandisa. Kuwedzera iyo radial runout yechishandiso panguva yekugadzira kuchaitawo kuti iyo machined surface rough.
6. Shandisa reverse milling panguva yekupedzisa
Munguva yekugaya kumberi, iyo gap chinzvimbo pakati peiyo lead screw uye nati inoshanduka, izvo zvinokonzeresa kusaenzana kwekudya kwetabhenakeri, zvichikonzera kukanganisa uye kudedera, zvichikanganisa hupenyu hwechishandiso chemuchina uye chishandiso uye iyo machining pamusoro roughness yeworkpiece.
Paunenge uchishandisa reverse milling, ukobvu hwekucheka hunochinja kubva kudiki kuenda kuhukuru, mutoro wezvishandiso zvakare unoshanduka kubva kudiki kuenda kuhukuru, uye chishandiso chakanyanya kugadzikana panguva yekugadzira. Cherechedza kuti izvi zvinoshandiswa chete panguva yekupedzisa. Kune rough machining, forward milling ichiri kushandiswa nekuti forward milling ine hupfumi hwepamusoro uye hupenyu hwematurusi hunogona kuvimbiswa.
7. Zvinonzwisisika kushandiswa kwekucheka mvura
Kushandisa zvine musoro kwekucheka fluid Aqueous solution nekutonhodza sezvo basa guru rine mhedzisiro shoma pakutema simba. Kucheka mafuta, iyo inonyanya kushanda semafuta, inogona kuderedza zvakanyanya simba rekucheka.
Kudzidzira kwakaratidza kuti chero bedzi kugadzirwa uye kurongeka kwechikamu chega chega chechishandiso chemuchina chakavimbiswa uye zvine musoro maitiro uye maturusi akasarudzwa, kukanganisa kweiyo radial runout yechishandiso pane iyo machining iko kweiyo workpiece inogona kuderedzwa.
