[0046] When the cutting distance measuring mechanism of the precision lathe operates normally, the second motor 321 is started. The second motor 321 drives the sliding seat of the second linear guide 322 to move back and forth. The sliding seat of the second linear guide 322 drives the connecting seat 313 to move. The connecting seat 313 drives the turning tool 311 and the cooling water pipe 312 to move. The third motor 323 is started. The third motor 323 drives the sliding seat of the third linear guide 324 to move left and right.

By controlling the second motor 321 and the third motor 323, the turning tool 311 and the cooling water pipe 312 can be moved to any position. The cooling water pipe 312 cools down the turning tool 311 during processing. According to the data measured by the distance measuring sensor 242, turning with different depths can be realized for different workpiece positions, avoiding the situation of scrapping due to excessive turning amount caused by different depths of the internal center holes of the workpieces.
