What we must pay attention to is that in a tool/toolholder device, the centrifugal force generated by the unbalanced state is proportional to the square of the spindle speed. In other words, a minute unbalance produced at 1 thousand revolutions per minute, the centrifugal force will increase 100 times at 10,000 revolutions, and 400 times at 20,000 revolutions. With the development trend of higher and higher spindle speeds, if the tool cannot keep rotating on the spindle centerline, it will become the main cause of additional imbalance. Therefore, good concentricity becomes more important. In the state of poor dynamic balance, the centrifugal force generated by the high-speed rotation of the spindle will cause preventable vibration or vibration. The effects of this vibration or vibration are as follows:

Puhui is a company that produces high-quality technical products such as high-speed spindles, precision toolholders and special tools. Therefore, the manufacturing of high-speed spindles must reach the G0.4 dynamic balance level. According to this high-level demand, the dynamic balance of the toolholders is produced to achieve the quality and Customer's demand for dynamic balance. In terms of optimization, users need to perform dynamic balance correction actions after the tie rod, tool holder, collet, nut, and tool are combined to obtain the best dynamic balance effect. The dynamic balance of a single handle alone cannot guarantee the final dynamic balance level after the combination, because the tie rods, collets, nuts and tools themselves also have a certain degree of weight and contain imbalance. Finally, any replacement or adjustment of tools, replacement of any parts of the tool holder, grinding of tools... etc. may affect the original dynamic balance level. A good dynamic balance level can improve machining accuracy, extend tool life, reduce machine vibration, and increase spindle life. Its importance is especially visible.
