在机械加工领域里从80年代末兴起的高速切削是当前金属切削与刀具技术发展的主要趋势,并已成为先进制造技术的一个重要特征,受到各国越来越多的重视。 数控机床的发展及其应用的普及使机械加工的辅助时间,包括换刀时间、换工件时间、调整换批时间,以及机床空程时间大大降低,成为60年代以来提高机加工效率的主要途径,使机床实际切削时间增加一倍以上。但是目前这一轮提高机加工效率的特点却是通过直接提高加工的切削速度和进给速度来实现的,这就是现在所说的高速切削,目的是使零件加工的有效切削时间大大减少。例如,与10年前相比,加
In the field of machining, high-speed cutting, which emerged from the late 1980s, is a major trend of current metal cutting and tool technology development. It has become an important feature of advanced manufacturing technology and is receiving more and more attention from all countries. The development of CNC machine tool and the popularity of its application make the auxiliary time of machining, including the tool change time, workpiece change time, adjust the batch change time, and greatly reduce the machine tool idle time, and become the main way to improve machining efficiency since the 1960s. The actual cutting time to more than double the machine. However, the current round of improving the machining efficiency is achieved by directly increasing the cutting speed and the feed speed. That is what we now call the high-speed cutting. The purpose is to reduce the effective cutting time of the parts machining greatly. For example, compared with 10 years ago, plus
