Description

Technical Field

[0001] The utility model relates to the technical field of numerical control optical machines, in particular to a main axis structure of a numerical control optical machine. Background Art

[0002] Optical machines are low-end products of CNC machine tools, and their technical content is relatively low compared to the core components of machine tools such as CNC systems. However, this does not mean that optical machines are very easy to manufacture. The design and manufacturing process level of optical machines are directly related to the quality, life and reliability of CNC machine tools, requiring manufacturers to have a high level of technology and management. When using CNC optical machines, the spindle needs to drive the workpiece or tool to rotate, and the CNC optical machine spindle needs to lubricate the bearings during use. Most of the lubricated oil is directly discharged and cannot be recycled, which not only pollutes the environment and increases operating costs, but also generates a lot of heat when processing the device, causing the temperature of the tool head and spindle to be too high, affecting the production efficiency of the workpiece.

[0003] Therefore, it is necessary to provide a new spindle structure of a CNC optical machine to solve the above technical problems. Utility Model Content
