Oomatshini bokugrumba kunye nokugaya ii-PCB zizixhobo ezibalulekileyo ekwenzeni iibhodi zesekethe eziprintiweyo, ezinceda ekudaleni imingxunya kunye neepateni ezifunekayo kwi-PCB. Ukusebenza ngokubanzi kwezi matshini kuxhomekeke kwizinto ezininzi, kubandakanya uyilo lwezinto zegranite ezisetyenziswa ekwakhiweni kwazo. Ngokwenza ngcono uyilo lwezi zinto, kunokwenzeka ukuphucula ukusebenza kakuhle kunye nokuchaneka kwezi matshini. Kweli nqaku, siza kuhlola ezinye iindlela zokuphucula ukusebenza koomatshini bokugrumba kunye nokugaya ii-PCB ngokusebenzisa uyilo lwe-granite element optimization.
I-Granite yinto ethandwayo yokwakha oomatshini bokugrumba kunye noomatshini bokugaya be-PCB ngenxa yokuqina kwayo okuphezulu, i-coefficient yokwandisa ubushushu obuphantsi, kunye nozinzo oluhle. Nangona kunjalo, uyilo lwezinto ze-granite lunokuchaphazela ukusebenza komatshini ngokubanzi. Ngokwenza utshintsho oluphambili kuyilo, kunokwenzeka ukuphucula ukusebenza komatshini ngeendlela ezahlukeneyo.
Okokuqala, imo kunye nobukhulu bezinto zegranite zinokuba nefuthe elikhulu ekusebenzeni komatshini. Ubukhulu bezinto zegranite kufuneka buphuculwe ukuqinisekisa ukuba zibonelela ngenkxaso eyaneleyo kumatshini ngelixa zinciphisa ubunzima bubonke. Ukongeza, ubungakanani kunye nemilo yezinto zegranite kufuneka zenzelwe ukunciphisa ukungcangcazela nokuphucula ukuqina komatshini. Oku kunokufezekiswa ngokuyila izinto ezinejometri ethile kunye nobukhulu ukuze kufezekiswe i-resonance frequency ephezulu, ekhuthaza uzinzo kwaye inciphise impembelelo yamandla angaphandle kumatshini.
Enye into ebalulekileyo ekwenzeni ngcono uyilo lwezinto zegranite kukunciphisa i-thermal expansion coefficient. Ukwandiswa kwe-thermal kunokubangela ukuba umatshini uphambuke kwindlela oyifunayo ngexesha lenkqubo yokubhola nokugaya, nto leyo enokuchaphazela kakubi ukuchaneka komatshini. Ukuyila izinto ezine-thermal expansion coefficients ephantsi kunokunceda ukunciphisa ezi ziphumo kunye nokuphucula ukuchaneka komatshini.
Olunye utshintsho olubalulekileyo loyilo ekufuneka luqwalaselwe kukugqitywa komphezulu wezinto zegranite. Ukugqitywa komphezulu wezinto kumisela ukungqubana phakathi kwezinto kunye nomatshini, kwaye kunokuchaphazela ukugudama kokuhamba komatshini. Ngokusebenzisa izinto zegranite ezipholisiweyo, kunokwenzeka ukunciphisa ukungqubana kunye nokuphucula ukugudama komatshini. Oku kunokuphucula ukuchaneka ngokubanzi komatshini ngokunciphisa amathuba okuphambuka kwinkqubo yokubhola kunye nokugaya.
Ukuqukumbela, ukuphucula uyilo lwezinto zegranite kwiimashini zokubhola ze-PCB kunye nezokugaya kunokuba nefuthe elikhulu ekusebenzeni kwazo. Ngokuqwalasela izinto ezifana nokuma nobukhulu, i-coefficient yokwandiswa kobushushu, kunye nokugqitywa komphezulu, kunokwenzeka ukuphucula ukusebenza kakuhle kunye nokuchaneka kwezi mashini. Ukuphucula ukusebenza kwezi mashini kunokukhokelela ekwandeni kwemveliso kunye neendleko ezincitshisiweyo, okwenza zibe lutyalo-mali oluxabisekileyo kuyo nayiphi na indawo yokuvelisa i-PCB.
