Me yasa kayan aikin hakowa na PCB suka fi son tushen granite na ZHHIMG®?

A fagen PCB daidai hakowa, ZHHIMG® granite tushe ya zama fifiko madadin karfe tushe saboda hudu core abũbuwan amfãni:
1. Tsare-tsare: Fitaccen juriya ga nakasa
Baƙar fata granite tare da yawa na 3100kg/m³ an zaɓi. Lu'ulu'u na ma'adinai na ciki suna da yawa kuma damuwa na ciki na halitta yana kusa da sifili. Idan aka kwatanta da matsalar zamewar lattice na firam ɗin ƙarfe a ƙarƙashin nauyin dogon lokaci, firam ɗin granite na iya kashe sama da 90% na nakasar, tabbatar da cewa na'urar hakowa tana kiyaye daidaiton matsayi na ± 1μm na dogon lokaci.
2. Babban ingancin shayarwar girgiza: Ana inganta daidaiton hakowa da sau 3
Ma'adinin ma'adinai na ciki na granite yana haifar da damping na halitta, wanda zai iya ɗaukar 90% na kuzarin girgiza yayin aikin hakowa (tushen ƙarfe na iya ɗaukar 30%) kawai. Wani ainihin ma'aunin masana'anta na PCB ya nuna cewa bayan shigar da tushe mai granite, ƙarancin bangon micro-rami mai girman 0.1mm ya ragu daga Ra1.6μm zuwa Ra0.5μm, kuma an tsawaita rayuwar sabis ɗin rawar sojan sau biyu.
Uku. Ƙarfafawar yanayin zafi: An rage tasirin bambance-bambancen zafin jiki
A coefficient na thermal fadada ne kawai 5.5 × 10⁻⁶ / ℃ (11.5 × 10⁻⁶ / ℃ ga karfe). Lokacin da ci gaba da aiki zafin jiki na kayan aiki ya tashi da 10 ℃, thermal nakasawa na granite tushe ne kasa da 5μm, yayin da cewa na karfe tushe iya isa 12μm, yadda ya kamata kauce wa ramin matsayi diyya lalacewa ta hanyar thermal fadadawa da ƙanƙancewa.
Iv. Daidaiton Gudanarwa: Garanti ta ma'auni na matakin nanometer
Ana sarrafa shi ta hanyar injin niƙa na CNC guda biyar, tare da ƙarancin sarrafawa a cikin ± 0.5μm / m, kuma yana goyan bayan T-ramummuka na al'ada, ramukan threaded da sauran hadaddun tsarin. Wani shari'ar daga wani masana'antar kayan aikin hakowa ya nuna cewa daidaiton ramin shigarwa na tushen injin granite ya kai ± 0.01mm, wanda shine 50% sama da na tushen injin karfe, yana rage lokacin ƙaddamar da kayan aiki.

Farashin da fa'idodin muhalli: Kodayake farashin farko shine 15% mafi girma, rayuwar sabis ta wuce shekaru 10 (shekaru 5 kawai don firam ɗin ƙarfe), kuma baya buƙatar kulawa. Abubuwan da ake fitarwa na carbon a cikin hakar ma'adinai da sarrafa granite sun kasance 40% ƙasa da waɗanda ke cikin narkewar ƙarfe, wanda ya dace da yanayin masana'antar kore.
