Technical Field

[0001] The utility model relates to a high-finish electric spindle for a CNC machine tool, belonging to the technical field of electric spindles for CNC machine tools. Background Art

[0002] The electric spindle of CNC machine tools shortens the length of the main transmission chain of the machine tool to zero, realizing the "zero transmission" of the machine tool. It has the advantages of compact structure, high mechanical efficiency, extremely high rotation speed, high rotation accuracy, low noise and small vibration. Therefore, it has been increasingly widely used in modern CNC machine tools.

[0003] There are still some problems with the existing CNC machine tool electric spindles during use. For example, during use, engine oil will penetrate the surface of the CNC machine tool electric spindle, causing the oil to flow to the surface of the part to be processed, affecting the subsequent use of the workpiece. In addition, when the machine tool electric spindle is installed inside the equipment, it is inconvenient to adjust it, which makes it unsuitable for different processing environments.
