Munyaya yekugadzira maturusi emuchina nemazvo, uko kunyangwe kuzununguka kwe micron-level kunogona kukanganisa kunaka kwekugadzirwa, basa re granite damping performance rave richichinja-chinja mutambo. Kuedzwa kwekuzununguka kwakaitwa munguva pfupi yapfuura nemakambani makuru ekugadzira manufacturing emuno nemasangano ekutsvagisa maindasitiri kwakasimbisa kuti kugadzirisa hunhu hwe granite damping kunogona kuderedza zvakanyanya kuzununguka kwe machining, nokudaro zvichiwedzera goho rezvikamu zvine manufacturing akakwirira kusvika ku15% kusvika ku20%. Kubudirira uku kwakarongerwa kukurumidzisa kuvandudzwa kweindasitiri ye machining yeChina nemazvo uye kupa rutsigiro rwakasimba rwehunyanzvi rwekutsiva maturusi emuchina epamusoro-soro mudzimba.
Zvishandiso zvemuchina zvine hungwaru hwakanyanya ndizvo zvinhu zvikuru zvinoshandiswa pakugadzira zvinhu zvakakosha muzvikamu zvakaita sema semiconductors, simba idzva, ndege uye mota. Munguva yekugadzira michina, kudedera kunokonzerwa nechishandiso chemuchina pachacho, maturusi ekucheka uye kushandira pamwe kwezvishandiso zvinowanzo tungamira pakuoma kwenzvimbo, kutsauka kwemativi uye kunyange kupfeka kwezvishandiso, zvichikanganisa zvakananga mwero wekukodzera kwezvigadzirwa zvakapedzwa. "Kune zviitiko zvekugadzira zvakanyatsonaka zvinoda kunyatsorongeka kwe submicron, kudzora kudedera ndiko kunonyanya kukosheswa," akadaro Li Ming, mainjiniya mukuru paChina Precision Machinery Industry Research Institute. "Mabhesi ezvishandiso zvemuchina wesimbi ane kugona kushoma kwekudzima, zvichiita kuti zviome kusangana nezvinodiwa zvekugadzira zvemazuva ano."
Zvichienderana neizvi, granite yakatsiva simbi yakakandwa zvishoma nezvishoma sechinhu chinodiwa pakugadzira maturusi emuchina nematafura ekushanda nemazvo nekuda kwehunhu hwayo hwakanaka. Granite yechisikigo ine kuomarara kwakanyanya, kudziya kwakaderera uye kuramba kupfeka zvakanaka, uye chimiro chayo chemukati chakasiyana chinoipa simba rekudzivirira mvura - mukana mukuru uyo simbi yakakandwa isingakwanise kuenzana nawo. Kuti vaongorore zvizere mukana wekushandisa granite damping mukuvandudza kugona kwekugadzira michina, timu yekutsvagisa yakabatana yakaumbwa nemabhizinesi nemayunivhesiti yakaita bvunzo dzakasiyana-siyana dzekudedera.
Kuyedzwa uku kwakaitwa panzvimbo yekugadzira michina ine 5-axis ultra-precision ine granite base, yakatarisana nekuyera vibration response yechishandiso chemuchina panguva yekucheka titanium alloy ne high-strength aluminium alloy parts. Chikwata ichi chakatanga chaedza vibration amplitude uye frequency ye cast iron base pasi pema processing parameters akafanana, ndokuzoitsiva ne granite base yakanga yaitwa specialized damping optimization treatment uye yakaita comparisonal example. Mhedzisiro yebvunzo yakaratidza kuti granite base yakaderedza vibration amplitude yechishandiso chemuchina ne40% kusvika 50% mu 50 Hz kusvika 2000 Hz frequency range, inova ndiyo main vibration frequency band inokanganisa machining precision.
"Chinhu chikuru chekugadzirisa mashandiro egranite damping chiri muzvikamu zviviri: kusarudzwa kwezvinhu uye tekinoroji yekugadzirisa," akatsanangura Wang Tao, director wehunyanzvi weShandong Xinhua Granite Precision Components Co., Ltd., mumwe wevatori vechikamu mubvunzo. "Takasarudza granite ore ine mineral composition yakafanana uye porosity shoma yemukati, uye mushure mekucheka nemazvo uye kurapwa kwekukwegura, takavandudza mashandiro edamping kuburikidza nekuchinja pamusoro uye embedded damping structures. Data rekuyedza vibration rakaratidza zvizere kuti matanho aya anogona kunwisa uye kubvisa vibration ye machining, kudzivirira kukanganiswa kwe resonance pamhando yekugadzira."
Kushandiswa kwakaitwa tekinoroji yegranite damping kwakatonyanya kushamisa. Mugadziri wezvikamu zvemotokari anotungamira muShanghai akashandisa tekinoroji iyi pakugadzira zvikamu zveinjini nemazvo. Mushure memwedzi wekuyedza kushanda, goho remacrankshafts nema camshafts rakawedzera kubva pa82% kusvika pa98%, uye kuomarara kwezvikamu kwakadzikira kubva paRa 0.8 μm kusvika paRa 0.4 μm, zvichizadzisa zvizere mwero wemhando yepamusoro yeinjini dzemotokari dzemhando yepamusoro. "Kuderedzwa kwezvigadzirwa zvisina kunaka hakuna kungoderedza mari yekugadzira chete asiwo kwakapfupisa kutenderera kwekugadzira, zvichiunza mabhenefiti makuru ehupfumi kubhizinesi," akadaro Zhang Wei, maneja wekugadzira wemugadziri.
Nyanzvi dzezveindasitiri dzakataura kuti kushandiswa zvakanaka kwetekinoroji ye granite damping performance optimization inyaya yakajairika yekubatanidzwa kwesainzi yezvinhu uye machining chaiyo. Nekufambira mberi kuri kuitwa matekinoroji akadai seAI ne digital twins, kuyedzwa kwe vibration uye damping optimization yezvikamu zve granite zvichafambirawo mberi kuhungwaru. Mune ramangwana, mabhizinesi anogona kugadzirisa ma damping parameters ema granite bases munguva chaiyo zvichienderana nezvinhu zvakasiyana zve machining, maitiro uye zvinodiwa zvemachinery kuburikidza nehurongwa hwekutarisa hungwaru, zvichiita kuti zvikwanise kudzorwa kwe vibration kwakagadzirirwa munhu uye kwakanyatsojeka.
Sangano reChina Machine Tool Industry Association rakaburitsa data rinoratidza kuti kudiwa kwemusika kwezvishandiso zvemuchina zvine granite kuri kukura ne25% pagore. Kugadziriswa kwekushanda kwegranite damping kuchawedzera kushandiswa kwegranite muindasitiri yezvishandiso zvemuchina, kwete chete munzvimbo dzekugadzira machining dzakanyatsojeka asiwo mumichina yekuyera yakabatana, michina yekugadzira laser nemimwe michina yepamusoro. Izvi zvichabatsira indasitiri yezvishandiso zvemuchina yeChina kuyambuka miganhu yehunyanzvi hwekudzora kunyatsojeka uye kuwedzera kukwikwidza kwayo pasi rose.
"Kuyedzwa kwekuzunguzika ndiyo hwaro hwekuvandudza mashandiro egranite damping, uye kuvandudzwa kwegoho remachining ndicho chinangwa chikuru chekuvandudza tekinoroji," akadaro Chen Hong, purofesa paSchool of Mechanical Engineering yeTsinghua University. "Munguva inotevera, ticharamba tichidzamisa tsvakiridzo pamusoro penzira yekunyungudutsa granite, kugadzira maitiro ekugadzirisa anoshanda uye nzira dzekuyedza, uye kupa zvakawanda mukusimudzira indasitiri yekugadzira nemazvo yeChina."
Sechinhu chakakosha pakugadzira michina yepamusoro-soro, granite iri kuramba ichiita basa rakakosha muindasitiri yekugadzira michina nemazvo. Kubudirira mukuvandudza tekinoroji yekuvandudza mashandiro, kwakasimbiswa nekuyedzwa kwesainzi kwekutenderera, kuchawedzera simba idzva mukusimudzira indasitiri yezvishandiso zvemuchina muChina uye kubatsira chikamu chekugadzira chemuno chemhando yepamusoro kutora danho rakasimba kuenda kuchikamu chepamusoro-soro chepasi rose chevalue chain.
