一引言随着我国社会主义革命和社会主义建设的飞速发展,要求机械制造工业以更快的速度制造出更多的精密机器设备,并且要求不断地提高机械加工的生产率,进一步发展生产,为多快好省地建设社会主义提供物质基础。提高切削速度是金属切削加工的发展趋向之一。目前,在高速磨削时,砂轮线速度可达80公尺/秒,因此,由于砂轮不平衡而引起强迫振动的可能性大大增加。
I. INTRODUCTION With the rapid development of China’s socialist revolution and socialist construction, the machinery manufacturing industry is required to manufacture more sophisticated machinery and equipment at an accelerated pace. It also demands that the productivity of machining should be continuously improved and the production should be further developed. Constructing socialism better and more economically provides the material basis. Increasing the cutting speed is one of the development trends of metal cutting. At present, the grinding wheel line speed is up to 80 m / s during high-speed grinding, so the possibility of forcing vibration due to the unbalance of the grinding wheel is greatly increased.
