[0020] 1. The present invention proposes a grinding head pressure adjustment structure for an ultra-precision machine. By setting a disassembly structure, the sliding plate is quickly raised and lowered using a first spring to unlock the pressure reducing plate, which can release the grinding head from the compression and fixation of the ball bearings. It can be easily disassembled and replaced from inside the second fixing column, ensuring process quality, improving equipment service life and safety, and improving processing accuracy, surface functionality and operating efficiency.

[0021] 2. The present invention proposes a grinding head pressure adjustment structure for an ultra-precision machine. By setting an adjustment structure, the grinding head is fixed inside the second fixed column using a pressure-reducing spring and a pressure-reducing plate.

Disassembly is performed by reversing the operation. Then, the I-shaped slider 17 of the grinding tool 12 is slid into the fixed groove 14, and the bolts 16 are tightened to fix the grinding tool 12 on the fixed plate 13. The position of the grinding head 26 is controlled by the first motor 8, the second motor 9 and the fourth motor 18, and the fifth motor 23 and the third motor 15 drive the grinding head 26 and the grinding tool 12 to rotate respectively, thereby achieving a full-range grinding effect on the grinding tool 12.
