Today's processing area, the hole turning, boring, parting and grooving and milling processes require long tool overhang, and increasingly common, in some cases, the same piece may need multiple types of processes. So far, a lot of processing performance levels long overhang applications is low, just reach out of the most basic requirements of the parts can be processed, that is not to happen cutting vibration, but not from talking about productivity. Because the tool vibrates, easily lead to decreased processing safety, poor part quality, high noise levels, short tool life, and even processed waste. Therefore, often only the ability to use less than the cutting edge of cutting parameters, thus increasing the processing costs, production time is also longer. In the milling step, the intermittent cutting operation, the process will occur in a tendency to vibration. Due to the use of long tool overhang, more milling process has vibration tendencies. Many methods can be one o'clock to avoid the tendency to induce vibration, such as using the correct cutters and tool path. However, when the tool overhang (distance spindle shank between the flange and the blade) exceed three times the diameter of the shank then, if you want the processing to meet the existing standard products, you need to take other measures. With the tool overhang milling tool diameter for the needs of the increasing fourfold or more, we have an urgent desire to overcome the effects of vibration, because vibration limits productivity. In particular, the axial depth of cut and feed rate had to maintain a low level, so the metal removal rate has not played its due level. In many cases, both the milling or internal turning, the tool must be used for long overhangs. For example, on multi-tasking machine, B-axis tool spindle is usually close to the workpiece hinder, so you must use a long tool overhang. In order to overcome the tendency of vibration, we need to use more high-tech means to manufacture vibration handle, which helps to better and more accurately the amplitude is reduced to a minimum. That is, we can accurately determine the type of a field of vibration damping and damping needed for the settings. In the latest research and development work, we in the design and application of vibration technology, the combination of a large number of professional and technical means and experience so as to achieve a more stable metal-cutting in the case of higher processing rate.
