在汽车大量生产中,所需要的带孔的销钉零件(见图1),其品种和数量很多。为适应生产需要,我们制造了一台Z029四工位双面加工钻孔倒角鼓轮式组合机床。其主要特点是:机床效率高,每小时加工1200件;更换相应衬套可加工直径和长度不同的零件二十余种;可 In the mass production of automobiles, the required pin parts with holes (see Fig. 1) are many in variety and number. In order to meet production needs, we have created a Z029 four-station double-sided drilling chamfer drum combination machine. Its main features are: high machine efficiency, processing 1200 per hour; replacement of the corresponding bushings can be processed diameter and length of different parts of more than 20 species;
