提高生产率是机械制造领域的永恒课题,也是当前机械制造领域普遍关注的问题。高速加工是目前获得高生产率的重要手段,关键在于创造条件,迅速普及。机械制造领域当前发展的特点是:难切削材料的大量出现使加工难度明显增加;加工中也提出了许多需要迫切解决的课题,如硬切削;为了保护环境,要求少用或不用切削油剂,即实现干切削或半干切削。总之,机械制造面临许多难题,在这样的情况下,为了提高生产率,必须综合利用有关的一切技术进 Improving productivity is an eternal topic in the field of machinery manufacturing, and it is also a common concern in the field of machinery manufacturing. High-speed processing is an important means of achieving high productivity. The key is to create conditions and popularize rapidly. The current development in the field of mechanical manufacturing is characterized by a large number of difficult-to-cut materials so that the processing difficulty is obviously increased; many problems that need to be urgently solved are raised during processing, such as hard cutting; in order to protect the environment, less or no cutting oil is required, That is to achieve dry or semi-dry cutting. In short, machinery manufacturing faces many problems, in which case in order to increase productivity, it is necessary to comprehensively utilize all relevant technologies
