Kuki ibikoresho byo gucukura PCB bikunda ZHHIMG® granite?

Mu rwego rwo gucukura neza PCB, base ya ZHHIMG® granite yahindutse uburyo bwiza bwo guhitamo ibyuma kubera ibyiza bine byingenzi:
1. Imiterere ihamye: Kurwanya imbaraga zidasanzwe
Granite yumukara hamwe nubucucike bwa 3100kg / m³ byatoranijwe. Imyunyu ngugu yimbere ni yuzuye kandi imihangayiko yimbere iri hafi ya zeru. Ugereranije n'ikibazo cyo kunyerera cya lattice yibikoresho byicyuma munsi yumutwaro muremure, amakadiri ya granite arashobora guhagarika hejuru ya 90% ya deformasiyo, akemeza ko igikoresho cyo gucukura gikomeza guhagarara neza kuri mm 1μm mugihe kirekire.
2. Gukoresha neza kwinyeganyeza neza: Gukora neza neza byongerewe inshuro 3
Imyunyu ngugu y'imbere ya granite ikora damping naturel, ishobora gukuramo 90% yingufu zinyeganyega mugihe cyo gucukura (ibyuma bishobora gukuramo 30% gusa). Ibipimo nyabyo byakozwe na PCB byerekana ko nyuma yo gushyiraho base ya granite, ubukana bwurukuta rwa 0.1mm rwa mwobo rwamanutse ruva kuri Ra1.6μm rugera kuri Ra0.5μm, kandi ubuzima bwumurimo wa biti bwongerewe inshuro ebyiri.
Bitatu. Ubushyuhe bukomeye bwumuriro: Ingaruka zubushyuhe butandukanye ziragabanuka
Coefficient yo kwagura ubushyuhe ni 5.5 × 10⁻⁶ / ℃ (11.5 × 10⁻⁶ / ℃ kubyuma). Iyo ubushyuhe bukomeza bwibikoresho byazamutseho 10 ℃, ihindagurika ryumuriro wa base ya granite ntiriri munsi ya 5 mm, mugihe iy'icyuma gishobora kugera kuri 12 mm, bikarinda neza imyanya yumwobo iterwa no kwaguka kwinshi no kugabanuka.
Iv. Gutunganya neza: Byemejwe na nanometero-urwego
Itunganywa na mashini itanu ya CNC yo gusya, hamwe nuburinganire bugenzurwa muri ± 0.5μm / m, kandi igashyigikira T-slots yihariye, umwobo wubatswe hamwe nizindi nzego zigoye. Urubanza ruvuye mu ruganda rukora ibikoresho rwo gucukura rwerekana ko aho umwobo ushyizwe neza neza na base ya mashini ya granite igera kuri .01 0.01mm, ikaba iri hejuru ya 50% ugereranije n’icyuma cy’imashini, bigabanya cyane igihe cyo gutangiza ibikoresho.

Ibiciro nibyiza kubidukikije: Nubwo igiciro cyambere kiri hejuru ya 15%, ubuzima bwa serivisi burengeje imyaka 10 (imyaka 5 gusa kumurongo wibyuma), kandi ntibisaba kubungabungwa. Imyuka ya karubone mu bucukuzi bw'amabuye y'agaciro no gutunganya granite iri munsi ya 40% ugereranije n'iy'icyuma gishongesha ibyuma, ibyo bikaba bihuye n'ibikorwa byo gukora icyatsi.
