在大量和成批生产中,广泛采用工序高度集中的专用设备,已成为近十年来机械制造工艺发展的一个特点。在机械车间里,广泛使用多工位自动和半自动车床、组合机床、钻镗床和攻丝机床、多轴铣床和多头磨床以及自动线。对模压、装配、包装及其它工序也开始采用多工位半自动机。 In a large number and mass production, extensive use of special processes with highly concentrated processes has become a feature of the mechanical manufacturing process in the last decade. In the machine shop, a wide range of multi-station automatic and semi-automatic lathes, combination machine tools, boring and drilling machines and tapping machines, multi-axis milling machines and multi-head grinder and automatic lines. For molding, assembly, packaging and other processes have also begun to use multi-station semi-automatic machine.
