[0022] This utility model provides, for example Figures 1-5 The high-precision CNC honing machine shown has an adaptive honing head structure, including a honing head body 1. An inner groove 2 is provided in the middle of the outer side of the honing head body 1. Multiple protruding blocks 3 are fixedly connected inside the inner groove 2. The multiple protruding blocks 3 are distributed at equal distances around the center of the honing head body 1. A locking block 13 is provided between two adjacent protruding blocks 3. The locking block 13 is fixedly connected to the inner groove 2. An oilstone 4 is locked to the outside of the locking block 13. A connecting rod 6 is connected to the top of the honing head body 1.

[0023] The connecting rod 6 can be connected to a drive mechanism such as a motor. The motor drives the honing head body 1 to rotate, thereby making the honing head body 1 rotate. After the honing head body 1 rotates, it makes a hole in the object through the oilstone 4 and performs polishing.
