2 Isingeniso sezinto zokwakha

Njengoba kukhonjisiwe kuMdwebo 1, ingxenye yepulasitiki iyinhlangano kagesi ye-ABS blade epulasitiki enobubanzi besayizi ka-250 × 250 × 50mm. Ukumodela kugcwaliswa kakhulu ku-Pro / E ngokuqina ebusweni ukuze kube umzimba oqinile, bese usebenzisa i-Pro / Isikhunta ku-Pro / E Imodyuli iyabona ukuhlukaniswa, nomphumela ohlangothini ntathu womgodi nomgogodla ngemuva kokuhlukaniswa kukhonjisiwe kuMdwebo 2.

Izidingo zobuchwepheshe: 

• ABIzinto ezibonakalayo ABS; 
• Ubukhulu bodonga lwengxenye yepulasitiki bungu-2mm; 
• Ingxenye yepulasitiki akumele ibe nezimbobo, imifantu nokunye ukukhubazeka; 
• Ubuso bengxenye yepulasitiki akumele ibe nama-burrs (i-flash); 
• Usayizi wokuvula ukhonjelwe kumodeli ye-3D.

Ukuze ulwelwesi isikhunta ingxenye plastic, it is ikakhulukazi edingekayo ukuze umshini lwalugobile ebusweni ukuma blade, kanye nokugcina mpo kanye nokunemba kwangaphakathi umgodi ohlangothini odongeni, ukuze kuqinisekiswe ukuxhumana okuseduze phakathi komgogodla , futhi lapho kwakhiwa ingxenye yepulasitiki Ngakho-ke ngeke kube khona ukukhanya. Ngaphezu kwalokho, ukuze kwenziwe lula ukufakwa kodonga olungaphandle lomgodi nomgogodla, umgodi ojiyile uvame ukucutshungulwa umumo wesigaxa, ukuze udonga lohlangothi nendawo engezansi kungabi okungaqondile, kepha ithambeka eliwumqansa engela ethile mpo, mayelana 1 ° ~ 5 °, kudingeka sinake ngesikhathi machining. Okulandelayo inqubo yokuhlaziya ngomshini womgodi.

Le ngxenye eyakha isikhunta idinga ukuthi icutshungulwe izinhlangothi ezimbili, ngaphambili nangemuva. Uhlangothi olungaphambili lugaya ngaphakathi ingaphakathi lesikhala nangaphezulu ekugcineni. Ngokubekwa, udonga lohlangothi olungaphandle kufanele lusolwe ngokunemba. Ngemuva kokuthi uhlangothi lwangaphambili lucutshunguliwe, okokusebenza kuphenduliwe, indawo engezansi iyasongwa, bese kuthi umsele onqenqemeni wodonga lohlangothi olungaphandle ucutshungulwe.
