金属切削加工是当前机械制造工业的主要工艺。它与企业的“上质量、上品种、上水平”和提高经济效益有着密切的关系。金切也是衡量一个国家、一个地区工业技术水平高低的重要标志之一。国民经济高速发展的需要,以及国际市场竞争的日益加剧,大大促进了机械制造和金切技术的发展,使现代生产的主要任务集中在提高生产率和产品质量及降低成本上。 Metal cutting is the main process of the current machinery manufacturing industry. It and the business of “quality, variety, on the level” and improve economic efficiency are closely related. Golden cut is also one of the important indicators of the level of industrial technology in a country and a region. The rapid development of the national economy and the increasingly fierce competition in the international market have greatly promoted the development of mechanical manufacturing and metal cutting technology and have made the major tasks of modern production focused on improving productivity and product quality and reducing costs.
