Kwicandelo lokubhola ngokuchanekileyo kwe-PCB, isiseko segranite se-ZHHIMG® siye saba yindlela ekhethwayo endaweni yesiseko sentsimbi ngenxa yeenzuzo zayo ezine eziphambili:
1. Ulwakhiwo oluzinzileyo: Ukumelana okugqwesileyo nokuguquguquka
Kukhethwa igranite emnyama enobunzima obuyi-3100kg/m³. Iikristale zeminerali zangaphakathi zixinene kwaye uxinzelelo lwangaphakathi lwendalo lusondele kwi-zero. Xa kuthelekiswa nengxaki yokutyibilika kwelattice yeefreyimu zentsimbi phantsi kwemithwalo yexesha elide, iifreyimu zegranite zinokucinezela ngaphezulu kwe-90% yokuguquka, okuqinisekisa ukuba isixhobo sokugrumba sigcina ukuchaneka kokubeka indawo ye-±1μm ixesha elide.
2. Ukusebenza kakuhle kokufunxa ukungcangcazela okuphezulu: Ukuchaneka kokubhola kuphuculwe kathathu
Ukungqubana kwangaphakathi kwezimbiwa zegranite kwenza ukudambisa kwendalo, okunokufunxa i-90% yamandla okungcangcazela ngexesha lenkqubo yokugrumba (iziseko zentsimbi zinokufunxa i-30% kuphela). Umlinganiselo wokwenyani womenzi we-PCB othile ubonisa ukuba emva kokufaka isiseko segranite, uburhabaxa bodonga olunemingxuma emincinci oluyi-0.1mm behle ukusuka kwi-Ra1.6μm ukuya kwi-Ra0.5μm, kwaye ubomi benkonzo ye-drill bit bongezwe kabini.
Isithathu. Uzinzo oluqinileyo lobushushu: Impembelelo yomahluko wobushushu iyancitshiswa
I-coefficient yokwandiswa kobushushu yi-5.5×10⁻⁶/℃ kuphela (11.5×10⁻⁶/℃ kwintsimbi). Xa ubushushu obuqhubekayo bokusebenza kwesixhobo bunyuka nge-10℃, ukuguquguquka kobushushu besiseko segranite kungaphantsi kwe-5μm, ngelixa oko kwesiseko sentsimbi kunokufikelela kwi-12μm, oku kuthintela ngempumelelo ukususwa kwendawo yomngxuma okubangelwa kukwanda kobushushu kunye nokucutheka.
Iv. Ukuchaneka kokucubungula: Kuqinisekiswe yimigangatho yenqanaba le-nanometer
Icutshungulwa ngumatshini wokugaya we-CNC one-axis ezintlanu, apho ubume bayo bulawulwa ngaphakathi kwe-±0.5μm/m, kwaye ixhasa ii-T-slots ezenziwe ngokwezifiso, imingxunya enemisonto kunye nezinye izakhiwo ezintsonkothileyo. Ityala elivela kumzi-mveliso othile wezixhobo zokubhola libonisa ukuba ukuchaneka kwendawo yokufaka umngxuma wesiseko somatshini wegranite kufikelela kwi-±0.01mm, okungaphezulu ngama-50% kunesiseko somatshini wentsimbi, okunciphisa kakhulu ixesha lokuqalisa kwezixhobo.
Iingenelo zeendleko kunye nokusingqongileyo: Nangona ixabiso lokuqala liphezulu nge-15%, ubomi benkonzo budlula iminyaka eli-10 (iminyaka emi-5 kuphela kwizakhelo zentsimbi), kwaye akufuneki kugcinwe. Ukukhutshwa kwekhabhoni ekumbiweni nasekucutshungulweni kwegranite kuphantsi ngama-40% kunaleyo ikwi-steel smelting, nto leyo ehambelana nomkhwa wokuvelisa izinto eziluhlaza.
