Abstract
The grinding of amorphous tape is regarded as extremely difficult due to the loading of the wheel during the grinding process and due to the crystallization of the amorphous tape caused by grinding heat. By taking advantage of excellent grinding performance of endless CBN abrasive belts, a new grinding wheel system constructed of endless CBN abrasive belts (namely a throw-away CBN wheel) was developed. In order to improve the ground workpiece surface waviness and roughness, a Low-frequency Vibration Grinding Method (LFVGM) was creatively put forward. In this paper, both the theoretical analysis and experiment research of LFVGM on improving ground workpiece waviness were carried out. An experiment investigation on grinding performance with a throw-away CBN wheel in continuous-feed grinding of amorphous tape was also conducted. Experiments show that the ground amorphous tape roughness Rmax value is below 0.8 μm by using # 600 endless CBN abrasive belts.
