一、机床的特点及其技术发展的三大阶段机床是人类制造各种机器必不可少的生产工具,是人类知识经验与智慧的结晶。机床具有创造性、实用性、商品性三大特点。机床的发展取决于社会需求、科技水平、人员素质三者的密切结合。社会需求是动力, 科技水平是基础,人员素质是根本。如无社会需求,机床发展就成无的放矢。如科技达不到,社会虽然急需,也难实现。如社会需要,科技能达,而人员素质下降,则机床发展就会停顿,甚至倒退。从1769年为制造蒸汽机汽缸
First, the characteristics of machine tools and the three major stages of technological development Machine tools are an indispensable production tool for mankind to manufacture various machines. They are the crystallization of human knowledge and wisdom. The machine tool has three characteristics of creativity, practicality, and commerciality. The development of machine tools depends on the close combination of social needs, scientific and technological level, and personnel quality. Social demand is the driving force, the level of science and technology is the foundation, and the quality of personnel is fundamental. If there is no social demand, the development of the machine tool will become nothing. If science and technology do not reach it, it will be difficult for society to achieve it. If society needs, science and technology can reach, and the quality of personnel declines, the development of the machine tool will stop or even go backwards. From 1769 to manufacture steam engine cylinders
