Mukuita kweCNC kutendeuka, dzimwe nhengo dzakatetepa-madziro dzinowanzogadziriswa. Paunenge uchishandura matete-amadziro maworkpiece, nekuda kwekusaomarara kusimba kweiyo workpiece, deformation yeatete-walled workpieces paCNC lathes kazhinji chinotevera chiitiko panguva yekutendeuka.

• 1. Nekuda kwemadziro akaonda eiyo workpiece, zviri nyore kukanganisa pasi pechiito che clamping pressure. Izvi zvinokanganisa kurongeka kwedimensional uye kurongeka kweiyo workpiece. Paunenge uchishandisa matatu-shaya chuck sezvakaratidzwa muFigure 1 kusungirira workpiece kuti igadzirise mukati megomba, ichaita zvishoma ikava katatu pasi pechiito chesimba rekuvhara, asi cylindrical gomba inowanikwa mushure mokushandura gomba. Apo shaya dzinosunungurwa uye workpiece yakabviswa, denderedzwa rekunze rinodzokera kune chimiro checylindrical nekuda kwekugadzirisa kupora, nepo gomba remukati rinova arc-shaped triangle sezvakaratidzwa mumufananidzo 2. Pakuyera ne micrometer yemukati, dhayamita D kumativi ose akaenzana.
• 2. Pasi pechiito chekucheka simba (kunyanya radial yekucheka simba), zviri nyore kubudisa vibration uye deformation, iyo inokanganisa dimensional accuracy, chimiro, nzvimbo yakarurama uye kuoma kwepamusoro kwe workpiece.
• 3. Nemhaka yokuti workpiece yakaonda, kupisa kwekucheka kuchaita kuti kupisa kwemafuta kunokonzera workpiece, izvo zvinoita kuti zvive zvakaoma kudzora ukuru hwebasa. Kune simbi yakatetepa-yakakomberedzwa workpieces ine yakakura mutsara wekuwedzera coefficients, senge inoenderera semi-yakapedza kutendeuka uye kupedzisa kutendeuka mune imwe yekumisikidza, iyo inopisa deformation yeworkpiece inokonzerwa nekupisa kwekucheka kuchakanganisa zvakanyanya kurongeka kwayo, uye dzimwe nguva kunyange kugadzira iyo workpiece. Yakanamira pafixture.

Isu tinoziva kuti akaremara matete-walled workpieces anogadziriswa neCNC lathes, saka chii chatinofanira kuita nezve deformation yeatete-walled workpieces paCNC lathes? Mhinduro dzinoverengeka dzinotsanangurwa pazasi.

• 1. Iyo workpiece yakakamurwa kuita rough parts. Munguva yekutendeuka kwakashata munhanho yekupedzisa kutendeuka, nekuda kweiyo yakakura yekucheka margin, iyo clamping simba rakakura zvishoma, uye deformation inoenderana yakakura; panguva yekupedzisa kutendeuka, simba rekuvhara rinogona kuva diki zvishoma, uye kune rumwe rutivi, iyo clamping yakaremara. Kune rimwe divi, inogona zvakare kubvisa deformation inokonzerwa neakanyanya kucheka simba panguva yekutendeuka kwakashata.
• 2. Paunenge uchishandisa geometric parameters kuti uite zvakanaka-shanduka-yakaonda-yakakomberedzwa workpieces zvinonzwisisika, iyo rigidity inodiwa kuti ive yakakwirira, iyo wiper blade haisi nyore kuva yakareba (kazhinji 0.2-0.3mm), uye kucheka kunofanira kuva kwakapinza.
• 3. Wedzerai clamping yekubata sezviri kuratidzwa muMufananidzo 3. Shandisai sleeve yakatsemuka kana mamwe shaya dzakapfava. Iyo yekubata kumeso inokwidziridzwa, kuitira kuti iyo clamping simba igovaniswa zvakaenzana pane workpiece, kuitira kuti workpiece irege kuremara nyore panguva yekuvhara.
• 4. Kunyatsodira mvura yekucheka. Nokunyatsodurura mvura yekucheka, kuderedza kutonhora kwekucheka uye kuderedza kupisa kwekushisa kwe workpiece.
• 5. Wedzera nzira mbabvu. Mamwe mabasa akatetepa-akakomberedzwa anogadzirwa zvakanyanya neakawanda maitiro mbabvu panzvimbo yekurovera kuti awedzere kuomarara pano, kuitira kuti iyo clamping simba riite pane maitiro mbabvu kudzikisa deformation yeworkpiece. Mushure mekugadzirisa kwapera, maitiro embabvu anobviswa. .
• 6. Kana axial clamping zvigadziri inofanira kushandiswa kushandura matete-walled workpieces, radial clamping haifanirwe kushandiswa zvakanyanya sezvinobvira, uye axial clamping nzira inoratidzwa muFigure 4 inosarudzwa. Iyo workpiece inosungirirwa axially nekuguma kwechiso che axial clamping sleeve (sleeve yakarukwa). Sezvo iyo clamping force F ichigoverwa pamwe neaxial kutungamira kweiyo workpiece, iyo axial rigidity yeworkpiece yakakura, uye hazvisi nyore kugadzira clamping deformation.
