Kodi kugwedezeka ndi kuchuluka kwa phokoso la zida za granite mumakina obowola ndi mphero a PCB ndi chiyani?

Makina obowola ndi mphero a PCB ndi zida zofunika popanga matabwa osindikizidwa (PCBs). Amagwiritsidwa ntchito pobowola mabowo ndi njira zamphero pa PCBs, zomwe zimafuna kulondola kwambiri komanso kulondola kuti zitsimikizire magwiridwe antchito a PCB. Kuti akwaniritse kulondola koteroko, makinawa ali ndi zida zapamwamba kwambiri, kuphatikizapo granite.

Granite ndi chisankho chodziwika bwino pa maziko, mizati, ndi zigawo zina za PCB pobowola ndi makina mphero. Ndi mwala wachilengedwe wokhala ndi kukhazikika kwapadera, kukhazikika, komanso kukana kusinthasintha kwa kutentha, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pamakina olondola. Granite ilinso ndi zinthu zabwino kwambiri zochepetsera kugwedezeka zomwe zimathandizira kuchepetsa phokoso ndikuwonjezera kulondola.

Kugwedezeka ndi phokoso la zigawo za granite mu PCB pobowola ndi makina ophera ndizochepa poyerekeza ndi zipangizo zina monga aluminiyamu kapena chitsulo choponyedwa. Makinawa amakhala olondola kwambiri komanso olondola makamaka chifukwa cha kukhazikika kwawo komanso kugwedera kwamphamvu, komwe kumalimbikitsidwa kwambiri pogwiritsa ntchito zida za granite. Kuuma kwa zinthu za granite komanso kuchuluka kwake kumathandizira kuyamwa ndikuchotsa mphamvu yakugwedezeka kwa makina ndikuchepetsa phokoso.

Kafukufuku wambiri wachitika kuti ayeze kugwedezeka ndi kuchuluka kwa phokoso la zigawo za granite mu PCB pobowola ndi mphero makina. Zotsatirazi zikuwonetsa kuti makina ogwiritsira ntchito zida za granite amakhala ndi kugwedezeka kochepa komanso phokoso lochepa, zomwe zimapangitsa kuti zikhale zolondola kwambiri, zolondola, komanso zapamwamba poyerekeza ndi makina ena. Makhalidwe amenewa n'kofunika makamaka PCB kupanga, kumene ngakhale pang'ono zolakwa mobowola mabowo ndi milled njira kungachititse kuti PCBs kulephera.

Pomaliza, kugwiritsa ntchito zida za granite pamakina obowola ndi mphero a PCB kumapereka maubwino angapo, kuphatikiza kulondola, kulondola, komanso mawonekedwe apamwamba. Kugwedezeka kwamakina ndi kuchuluka kwa phokoso kumachepetsedwa kwambiri, makamaka chifukwa cha kugwetsa kwamphamvu kwa granite. Choncho, opanga PCB akhoza kukwaniritsa zotsatira zabwino ndi zokolola apamwamba ndi makina amenewa, kuwapanga ndalama zofunika kwa malo aliwonse PCB kupanga.
