Kwintsimi ye-PCB yokomba ngokuchanekileyo, isiseko se-granite ye-ZHHIMG® ibe yeyona ndlela ikhethwayo kwisiseko sentsimbi ngenxa yeenzuzo zayo ezine eziphambili:
1. Isakhiwo esizinzile: Ukuchasana okubalaseleyo kwi-deformation
Igranite emnyama enobunzima obuyi 3100kg/m³ ikhethiwe. Iikristale zamaminerali zangaphakathi zixinene kwaye uxinzelelo lwendalo lwangaphakathi lusondele kwi-zero. Xa kuthelekiswa nengxaki ye-lattice slip yezakhelo zentsimbi phantsi kwemithwalo yexesha elide, iifreyimu zegranite zinokucinezela ngaphezu kwe-90% ye-deformation, iqinisekisa ukuba isixhobo sokomba sigcina ukuchaneka kokumisa kwe-±1μm ixesha elide.
2. Ukusebenza kakuhle kokufunxa ukungcangcazela: Ukuchaneka kokugrumba kuphuculwe ngamaxesha e-3
I-friction yangaphakathi yeeminerali ye-granite yenza i-natural damping, enokuthi ifunxe i-90% yamandla okungcangcazela ngexesha lenkqubo yokomba (iziseko zentsimbi zinokufunxa kuphela i-30%). Umlinganiselo wokwenene womenzi we-PCB ubonisa ukuba emva kokufaka isiseko segranite, uburhabaxa bodonga lwe-0.1mm micro-hole lwehla ukusuka kwi-Ra1.6μm ukuya kwi-Ra0.5μm, kwaye ubomi benkonzo ye-drill bit yandiswa ngamaxesha amabini.
Ntathu. Ukuzinza okuqinileyo kwe-thermal: Impembelelo yokuhluka kweqondo lokushisa iyancitshiswa
I-coefficient yokwandiswa kwe-thermal kuphela i-5.5 × 10⁻⁶ / ℃ (11.5 × 10⁻⁶ / ℃ yensimbi). Xa ukushisa okuqhubekayo kwezixhobo zokusebenza kuphakama nge-10 ℃, i-thermal deformation yesiseko se-granite singaphantsi kwe-5μm, ngelixa isiseko sensimbi sinokufikelela kwi-12μm, sigweme ngokufanelekileyo i-offset yesigxina somngxuma obangelwa ukwanda kwe-thermal kunye nokunciphisa.
Iv. UkuLungiswa kokuChaneka: Kuqinisekiswe ngemigangatho yenqanaba le-nanometer
Icutshungulwa ngumatshini wokugaya i-CNC ene-axis emihlanu, kunye ne-flatness elawulwayo ngaphakathi kwe-± 0.5μm / m, kwaye ixhasa i-T-slots yesiko, imingxuma enemisonto kunye nezinye izakhiwo ezinzima. Ityala elivela kumzi-mveliso othile wezixhobo zokugaya libonisa ukuba indawo yokubeka umngxuma ukuchaneka kwesiseko somatshini wegranite ifikelela ku-± 0.01mm, eyi-50% ephezulu kunesiseko somatshini wentsimbi, ukunciphisa kakhulu ixesha lokumisela izixhobo.
Iindleko kunye neenzuzo zokusingqongileyo: Nangona iindleko zokuqala ziyi-15% ephezulu, ubomi benkonzo budlula iminyaka eyi-10 (iminyaka emi-5 kuphela kwiifreyimu zetsimbi), kwaye ayifuni ukugcinwa. Ukukhutshwa kwekhabhoni emigodini kunye nokusetyenzwa kwegranite kungaphantsi kwama-40% kunoko kunyibilikiswa kwentsimbi, okuhambelana nomkhwa wokwenziwa kohlaza.
