[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. Grooving is an important processing method in turning. The characteristics of chip formation and discharge make it unique in almost every aspect, and the internal grooving turning tool is mainly used for internal groove processing of workpieces.

[0003] When the internal grooving turning tool of the CNC lathe in the prior art processes the workpiece, the connected wire chips are discharged outward by the rotation of the workpiece and are not easy to break. The smaller chips are easily accumulated at the bottom of the groove due to the influence of centrifugal force, and the tool head and the inner wall of the workpiece are continuously worn during processing, causing processing vibration and inner wall patterns, affecting the processing quality. The chips cannot be discharged in time, and a dust suction device is often used to suck out the chips inside the workpiece after the processing is completed. Utility Model Content
