一、机械加工和组装生产工艺机械加工和组装生产的进步取决于零件机械加工和产品组装的发展水平,毛坯的质量及其形状尺寸与成品的接近程度,以及主要工序和辅助工序的自动化水平。近年来,在机器制造业中出现了许多先进的新工艺、新型刃具和磨具,研制出不少新型刀具材料,并十分重视零件机械加工和其它加工过程的机械化和自动化,机器和部件的组装和试验,以及采用新的
First, the mechanical processing and assembly production process Mechanical processing and assembly and production progress depends on the parts machining and assembly of the level of development, the quality of the blank and its shape and size and the proximity of the finished product, as well as the main processes and auxiliary processes automation level. In recent years, many advanced new technologies, new cutting tools and grinding tools have emerged in the machinery manufacturing industry, many new cutting tool materials have been developed, and mechanization and automation of mechanical machining of parts and other processing processes, assembly of machines and components have been emphasized And test, and adopt new ones
