德国SMK Krebge公司专业生产发动机和变速器部件,宣称应用断面分离技术,切开连杆轴承盖的新工艺生产柴油机和汽油机连杆。这种连杆用烧结金属粉末制成,在粉末的初期压制期间,连杆大端的内孔表面在以直径方向上对向的位置加工了两条沟槽。也可用另外的拉削方法来制成这两条沟槽。随后在锻造工序中,沟 Germany SMK Krebge company specializing in the production of engine and transmission components, claiming that the application of cross-section separation technology, connecting rod bearing cover cutting new technology for the production of diesel and gasoline engine connecting rod. The connecting rod is made of sintered metal powder and during the initial pressing of the powder, the inner surface of the large-diameter end of the connecting rod is machined with two grooves diametrically opposed to each other. It is also possible to make these two grooves with another broaching method. Then in the forging process, ditch
