Vibration-Assisted Grinding Vibration assisted grinding is a grinding method in which a certain frequency of vibration with an amplitude of about 10 µm is superimposed to the cutting tool or the workpiece to achieve better cutting performance. When a high frequency vibration (more than 16 kHz) is applied to the cutting
Features of Vibration Grinding Machine: First, the world's advanced spiral three-dimensional space motion principle is adopted to make the parts and the barrel polishing tool grind each other. Second, it is suitable for the finishing process of a large number of small and medium-sized parts, and improves the work efficiency by 6-10 times.
But, you probably remember that a vibration grinder works due to the reciprocating movements of the sole, and the larger the amplitude of these movements, the faster the grinding occurs, but the weaker its quality, and therefore the smaller the amplitude, the slower the machine grinds, but of higher quality Vibratory grinders with a vibration amplitude of 1.5-3.0 mm are used for …

The Effect of Torsional Vibration in Longitudinal . Figure 8a presents the vibration curve of the tool with rotation and without load when the tool grinding speed was 5.03 m/s (12,000 r/min), the output power of the ultrasonic power supply was 45% and the maximum amplitude of the electroplated grinding tool was 27.2 μm.
However, it has the disadvantage that the vibration amplitude of the spindle is relatively small. Then, Choi et al. used the finite element method to design and obtain a rotary ultrasonic grinding device with a tool end diameter of 10 mm. A series of grinding experiments were carried out on Ti–6Al–4V, FCD700 and S45C by using this device.
Moreover, the amplitude of the modulations of the GMF by the worm rotation frequency will be increased because of the grinding forces. Therefore, the definition of a monitoring feature for high feed will be based on the above described vibration
