[0002] Gear machining machine tools are key machining machine tools for manufacturing gears. CNC gear turning machines are common high-precision gear machining equipment. The principle of gear turning machines is to use tools similar to milling cutters to cut synchronously with workpieces. The worktable can process tracks in a certain arc in multiple directions at the same time. It is suitable for processing arc gears or gears that require special tooth surface shapes.

[0003] There is a track door on the body of the CNC gear turning machine. There are two common types of track doors, a track sliding door that moves left and right and a track sliding door that lifts vertically. When the CNC gear turning machine is used for a long time, it will be subject to wear, pollution or interference from debris and impurities. The track contact surface between the track sliding door and the body will become rough due to the accumulation of debris and impurities, resulting in greater friction, affecting the lifting and lowering of the track sliding door. When the track door on the body of the CNC gear turning machine is opened, there is a design problem that there is no design to block the debris and impurities between the track sliding door and the track contact surface. For this reason, the present application proposes a CNC gear turning machine. Utility Model Content
