MuCNC manhamba ekudzora midziyo, kunyangwe granite yave chinhu chakakosha nekuda kweiyo yakasarudzika zvimiro, zvipingamupinyi zvayo zvemukati zvinogona zvakare kuve nemhedzisiro pakuita kwemidziyo, kushanda zvakanaka uye mutengo wekugadzirisa. Izvi zvinotevera ongororo yezvakakonzeresa zvinounzwa nekushomeka kwegranite kubva kune akawanda mativi:
Chekutanga, zvinhu zvacho zvakanyanya brittle uye zviri nyore kuputsika uye kukuvara
Core drawback: Granite ibwe rechisikigo uye rinonyanya brittle zvinhu zvisina kusimba kusimba (kukanganisa kusimba kukosha kunosvika 1-3J/cm², iyo yakadzikira zvakanyanya kupfuura 20-100J/cm² yesimbi yemidziyo).
Impact pamidziyo yeCNC:
Kuiswa uye njodzi dzekufambisa: Panguva yekuungana kana kubata kwemidziyo, kana ikabatwa kana kudonhedzwa, zvikamu zvegranite (senge mabhesi uye njanji) zvinotapukira kutsemuka kana makona akachekwa, zvichiita kuti kukundikana kwechokwadi. Semuyenzaniso, kana granite chikuva chemuchina wekuyeresa wetatu chikaita makatsemuka akavanzika nekuda kwekushanda zvisina kunaka panguva yekuisa, zvinogona kutungamira kuderera zvishoma nezvishoma kwekupfava pakushandiswa kwenguva refu, zvichikanganisa mhedzisiro yekuyera.
Njodzi dzakavanzwa mukugadzirisa maitiro: Kana CNC mudziyo ukasangana nekuremerwa nekukasira (senge chishandiso chinodhumhana neiyo workpiece), njanji yegwara kana matafura ekushanda anogona kutyoka nekuda kwekutadza kumirisana nekukasira kwesimba rekuita, zvichikonzera kuti michina ichivharika pakugadzirisa, uye kunyange kukonzeresa cheni yekutadza chaiko.
Chechipiri, kuoma kwepamusoro kwekugadzirisa kunogadzirisa kugadzirwa kwezvivako zvakaoma
Core drawbacks: Granite ine kuoma kwakanyanya (6-7 pachikero cheMohs), uye inoda kugadzikwa pasi uye kugadziriswa nemidziyo yakakosha semavhiri edhaimondi, zvichikonzera kuderera kwekugadzirisa (kushanda kwekugaya kunongova 1/5 kusvika 1/3 yezvigadzirwa zvesimbi), uye mutengo wekugadzirisa nzvimbo dzakakombama dzakakomba dzakakwira.
Impact pamidziyo yeCNC:
Mamiriro ekugadzira dhizaini: Kuti udzivise matambudziko ekugadzirisa, zvikamu zvegranite zvinowanzogadzirwa zviri nyore zvimiro zvejometri (senge mahwendefa, rectangular gwara regwara), zvichiita kuti zviome kuwana magonhi emukati akaomarara, mahwendefa akaomeswa akareruka uye zvimwe zvimiro zvinogona kuitwa nekukanda / kucheka nesimbi zvinhu. Izvi zvinotungamirira kune chokwadi chokuti uremu hwechigadziko chegranite inowanzove yakakura (10% -20% inorema kudarika simbi yakakandwa nokuda kwevhoriyamu imwechete), iyo inogona kuwedzera mutoro wose wezvigadzirwa uye inokanganisa kushanda kwekuita kwekuita panguva yekufamba-famba.
Kuchengetedza kwakanyanya uye mari yekutsiva: Kana kupfeka kwenzvimbo kana kukuvara kuzvikamu zvegranite, zvakaoma kuzvigadzirisa kuburikidza nenzira dzakaita sewelding kana kucheka. Kazhinji, chikamu chose chinoda kutsiviwa, uye zvikamu zvitsva zvinoda kudzoserwa pasi uye kurongeka kuti zvinyatsoita, zvichikonzera kuderera kwenguva refu (kutsiva kumwe chete kunogona kutora mavhiki e2-3), uye kuwedzera kukuru kwemari yekuchengetedza.
Iii. Kusava nechokwadi kweMasikirwo Akasikwa uye Kukanganisa Kwemukati
Core drawback: Sechisikigo chicherwa, granite ine isingadzoreki mukati mefissures, pores kana mineral tsvina, uye kufananidzwa kwezvinhu zvetsinga dzakasiyana kunosiyana zvakanyanya (density fluctuation inogona kusvika ± 5%, elastic modulus fluctuation ± 8%).
Impact pamidziyo yeCNC:
Precision kugadzikana kwengozi: Kana nzvimbo yekugadzirisa yechikamu ichiitika iine kuputika kwemukati, panguva yekushandiswa kwenguva refu, kuputika kunogona kuwedzera nekuda kwekunetseka, zvichiita kuti deformation yemunharaunda uye kukanganisa kururamisa kwemidziyo. Semuyenzaniso, kana njanji yegwara remuchina wekukuya weCNC ane maburi emhepo akavanzika, anogona kudonha zvishoma nezvishoma pasi peiyo high-frequency vibration, zvichikonzera kukanganisa kwakanyanyisa kwenjanji.
Batch performance misiyano: Zvishandiso zvegranite kubva kumabheji akasiyana zvinogona kusangana nekushanduka kwezviratidzo zvakakosha senge coefficient yekuwedzera kwekupisa uye kuita kwekunyorova nekuda kwekusiyana kwekuumbwa kwemamineral, izvo zvinokanganisa kuenderana kwekugadzirwa kwebatch nemidziyo. Kune otomatiki mitsara yekugadzira inoda kupindirana kwezvishandiso zvakawanda, misiyano yakadai inogona kutungamira mukupararira kwekunatswa kwekugadzirisa.
Chechina, inorema, iyo inokanganisa kushanda kwemasimba emidziyo
Core drawback: Granite ine high density (2.6-3.0g/cm³), uye huremu hwayo hunosvika 1.2 times iyo yesimbi yakakandwa uye 2.5 times iyo yealuminium alloy pasi pevhoriyamu imwe chete.
Impact pamidziyo yeCNC:
Motion response lag: Munzvimbo dzekumhanya-mhanya dzemachining kana mashanu-axis muchina, huwandu hukuru hwegireni huchawedzera inertia yemutsetse wemota / lead screw, zvichikonzera kunonoka kwekupindura panguva yekumhanyisa / kudzikisira (izvo zvinogona kuwedzera nguva yekutanga-yekumira ne5% kusvika 10%), zvichikanganisa mashandiro ekugadzirisa.
Kuwedzera kushandiswa kwesimba: Kutyaira zvinorema zvegranite zvikamu zvinoda zvakanyanya simba servo motors, izvo zvinosimudza simba rose rekushandisa kwemidziyo (zviyero chaizvo zvinoratidza kuti pasi pemamiriro ekushanda akafanana, kushandiswa kwesimba kwegireni base midziyo ndeye 8% -12% yakakwirira kupfuura iyo yemidziyo yesimbi yakakandwa). Kushandiswa kwenguva refu kuchawedzera mari yekugadzira.
Chechishanu, kugona kupikisa kuvhunduka kwemafuta kunogumira
Core drawback: Kunyange zvazvo granite ine yakaderera coefficient of thermal kuwedzera, kupisa kwayo conductivity kwakaipa (ine thermal conductivity ye 1.5-3.0W/(m · K) chete), inenge 1/10 iyo yesimbi yakakandwa), uye kamwe kamwe kushanduka kwekushisa kwemunharaunda kunowanzoita kuti iite kushushikana kwekushisa.
Impact pamidziyo yeCNC:
Tembiricha yemusiyano nyaya munzvimbo yekugadzira: Kana iyo yekucheka mvura yakanyatso bvisa nzvimbo yenzvimbo yegranite worktable, inogona kukonzera tembiricha gradient (senge tembiricha musiyano we5-10 ℃) pakati penzvimbo iyi nenzvimbo yakatenderedza, zvichitungamira kudiki deformation (deformation huwandu hunogona kusvika 1-3μm), iyo inokanganisa iko kurongeka kwegiya rekugadzirisa (microstelency consinding).
Njodzi yenguva refu yekuneta kwekupisa: Munzvimbo dzewekishopu dzinogara dzichitanga-ups uye kuvharika kana kusiyana kukuru kwekushisa pakati pemasikati neusiku, zvikamu zvegranite zvinogona kugadzira microcracks nekuda kwekudzokororwa kwekuwedzera kwekupisa uye kuputika, zvishoma nezvishoma zvichideredza kusimba kwechimiro.
