Toshewar injin wani sashe ne mai kama da akwati tare da sirara mai katanga mai hadadden tsari, wanda ke da saukin lalacewa yayin sarrafa shi, wanda ke bukatar tabbatar da ingancinsa. A halin yanzu, sarrafawa da samar da injuna galibi suna nufin kammala samarwa akan layukan sassauƙa waɗanda ke ƙarƙashin ikon cibiyoyin injin CNC. Wannan fasaha yana da manyan buƙatu don fasahar sarrafa kansa da ƙarancin farashin samarwa. Bugu da ƙari, a cikin aiki na shingen silinda, daidaiton kowane hanyar haɗi ya kamata ya kasance mai girma sosai, in ba haka ba yana da wuya a cika ka'idodin wannan tsari. Mai zuwa shine takamaiman tsarin fasaha na sarrafa Silinda:

1. Silinda surface aiki

Abubuwan sarrafa saman silinda an raba su zuwa sarrafa jirgin sama da sarrafa tazara. Mashin din jirgin dai ya kunshi nakakar karshen fuska, kamar: sarrafa fuskar sama, kasa da gaba da bayanta. Yin aiki da ɓarna sau da yawa yana buƙatar matakai irin su m, honing, hakowa, reaming, da kuma tapping, ciki har da hollowing jaket ruwa, hawa ramuka, haɗa ramukan, piston Silinda ramukan, mai ramuka, da dai sauransu.

2. Silinda machining tsari
