科学技术的发展对切削加工提出了越来越高的要求,各行业对加工效率、加工精度和表面质量的要求越来越高。目前,精密、超精密技术及装备在我国的应用已不再局限于国防尖端和航空航天等少数部门,它已扩展到了国民经济的许多领域,应用规模也有较大增长。汽车、电子以及重型装备等行业,现都需要精密、超精密加工技术及设备,作为其迅速发展的支撑条件。 The development of science and technology has raised the higher and higher requirements for the cutting process. The requirements of processing efficiency, processing precision and surface quality in various industries are getting higher and higher. At present, the application of sophisticated and ultra-precision technologies and equipment in our country is no longer confined to a few departments such as the defense frontier and the aerospace industry. It has expanded to many fields of the national economy with a large increase in the scale of application. Industries such as automotive, electronics and heavy equipment now require sophisticated, ultra-precision machining techniques and equipment as their rapidly growing supportive conditions.
