Kuki ibikoresho byo gucukura bya PCB bikunda ishingiro rya ZHHIMG® granite?

Mu rwego rwo gucukura neza PCB, ZHHIMG® granite base yabaye uburyo bwo gusimbura icyuma bitewe n'inyungu enye z'ingenzi:
1. Imiterere ihamye: Irwanya cyane impinduka
Ibuye ry'umukara rifite ubucucike bwa 3100kg/m³ riratoranywa. Amabuye y'agaciro y'imbere ni menshi kandi imbaraga karemano z'imbere ni hafi ya zeru. Ugereranyije n'ikibazo cy'ingufu z'icyuma zigwa mu gihe kirekire, amabuye y'agaciro ashobora kugabanya 90% by'ihinduka ry'imiterere, bigatuma igikoresho gicukura gikomeza kugira imiterere ya ±1μm igihe kirekire.
2. Ubushobozi bwo gukoresha umuvuduko mwinshi: Ubuhanga bwo gucukura burushaho kwiyongeraho inshuro 3
Ubushyuhe bw'imbere mu byuma bya granite butuma habaho ubushyuhe karemano, bushobora kwinjiza 90% by'ingufu zihindagurika mu gihe cyo gucukura (ibyuma bishobora kwinjiza 30% gusa). Igipimo nyacyo cy'uruganda runaka rwa PCB kigaragaza ko nyuma yo gushyiraho ishingiro rya granite, ubukana bw'urukuta rwa 0.1mm rufite umwobo muto bwagabanutse kuva kuri Ra1.6μm kugera kuri Ra0.5μm, kandi igihe cyo gukora cy'imashini yo gucukura cyongereweho inshuro ebyiri.
Icya gatatu. Ubushyuhe buhamye: Ingaruka z'itandukaniro ry'ubushyuhe ziragabanuka
Igipimo cyo kwaguka k'ubushyuhe ni 5.5 × 10⁻⁶/℃ (11.5 × 10⁻⁶/℃ ku byuma). Iyo ubushyuhe buhoraho bw'ibikoresho buzamutseho 10℃, guhinduka k'ubushyuhe bw'ishingiro rya granite kuba munsi ya 5μm, mu gihe ubw'ishingiro ry'icyuma bushobora kugera kuri 12μm, bigatuma hirindwa ko umwobo uhinduka bitewe no kwaguka no guhindagurika k'ubushyuhe.
Iv. Ubuziranenge mu gutunganya: Byemejwe n'ibipimo ngenderwaho by'urwego rwa nanometer
Itunganywa n'imashini isya ya CNC ifite imirongo itanu, ifite ubugari bugenzurwa na ± 0.5μm/m, kandi ishyigikira imiyoboro ya T yihariye, imyobo ifite imigozi n'izindi nyubako zigoye. Urugero rwavuye mu ruganda rumwe rw'ibikoresho byo gucukura rugaragaza ko uburyo bwo gushyiraho umwobo w'imashini ya granite bungana na ± 0.01mm, ari na 50% hejuru y'aho imashini ikoresha ibyuma ikorera, bigabanya cyane igihe cyo gukoresha ibikoresho.

Ibiciro n'inyungu ku bidukikije: Nubwo ikiguzi cya mbere kiri hejuru ya 15%, igihe cyo gukora kirenga imyaka 10 (imyaka 5 gusa ku byuma bicukurwamo ibyuma), kandi ntibisaba kubungabungwa. Imyuka ihumanya ikirere mu bucukuzi no gutunganya granite iri hasi ho 40% ugereranyije n'iy'icyuma gishongeshwa, ibi bikaba bihuye n'icyerekezo cy'inganda zikora ibikomoka ku bimera.
