Usually refers to high-speed motor speed exceeds 10000r / min motor. They have the following advantages: First, because the speed is high, so high motor power density, and the volume is much less than the power of ordinary motor, can effectively save material. Second, can be connected to the prime mover, the abolition of the traditional gear box, sealed bearings high transmission efficiency, low noise. Third, due to the high speed motor moment of inertia, so fast dynamic response.High-speed machining technology more and more people's attention, it is not only for greater productivity, but also get high processing Ceramic Ball Bearings quality, and reduce production costs, and thus is considered to be the 21st century's most promising advanced manufacturing technology one. In the advanced industrial countries, this technology has been widely used in aviation, aerospace and die industries. In the past five years, the technology of our country has made considerable turbocharger bearings progress. Is a prerequisite for high-speed cutting, High-speed machine tools and virtual axis machine tools are groundbreaking major change. Whether ordinary or virtual axis CNC machine tools, a key component to achieve high-speed spindle unit remains.
