INSTRUCTIONS: [Technical field to which the invention pertains] The present invention relates to an abrasive cutting device, and more particularly to a suppression mechanism for abrading flutter. [Prior Art] According to the conventional processing of the object to be processed by the cutting mechanism, usually the object to be processed will generate chattering, which will eventually affect the precision of the processing of the object to be processed. To overcome such flutter, the current technology The sensor is used to measure the amplitude of the vibration generated during cutting. As shown in FIG. 1 , the spindle speed of the cutting mechanism is adjusted by signal feedback, or the spindle speed of the cutting mechanism is manually adjusted to suppress the waiting. The effect of the material flutter, but this type is active, and if the spindle speed of the cutting mechanism is adjusted frequently during the cutting process, the surface roughness of the workpiece and the precision of the workpiece to be processed cannot be ensured. In particular, grinders that must pay special attention to processing parameters and the environment. As for the workpiece clamping method of the cylindrical grinding machine, the workpiece is usually supported by the two top cores. Since the workpiece is naturally drooped due to the influence of gravity, it is often necessary to support by means of the center frame, as shown in Figures 2 and 3. The traditional center frame 10 is a two-point or two-point tool holder that is in contact with the workpiece. The tool holder can be adjusted. When the tool holder is adjusted to the optimal support position for contact with the workpiece, the tool holder lock will be used. Solidified, at this time with the tool holder and the workpiece, it is hard contact, because the workpiece is not completely round, the workpiece itself is also polished when the workpiece is being polished. 2008946126 To rotate, when the workpiece rotates, it will slide friction with the tool holder, and the knife The frame does not completely limit the workpiece, so the workpiece will produce chattering, resulting in poor quality of the processed workpiece. In view of this, in order to solve the above-mentioned defects, the inventor of the present invention has finally designed a suppression mechanism for grinding and cutting flutter, in order to solve the above-mentioned defects, in order to make a slight contribution to the industry of the grinding and cutting machine. SUMMARY OF THE INVENTION The primary object of the present invention is to provide a suppression mechanism for grinding and cutting flutter, which can employ a holder to cooperate with a vibration absorber to move along with the cutting point of the cutting tool, thereby absorbing the cutting time.
