The utility model discloses a rotating shaft braking structure in a machine tool. The rotating shaft braking structure comprises a rotating shaft which is arranged in a box body and can rotate. The dynamic brake pad is arranged on the box body, the static brake pad is arranged on the rotating shaft, and the static brake pad or the static brake pad and the dynamic brake pad are driven by the annular piston arranged on the box body to deform to achieve braking, so that the piston is prevented from being abraded by the dynamic brake pad, and meanwhile two braking modes can be provided; when the static brake pad and the dynamic brake pad are attached and a brake gap exists between the dynamic brake pad and the box body, the rotating shaft can have damping to avoid vibration, when the dynamic brake pad and the static brake pad are clamped by the annular piston and the box body, the rotating shaft can be prevented from rotating, and the positioning precision is improved. 本实用新型公开了一种机床中旋转轴制动结构，包括设置在箱体内能做旋转运动的旋转轴；在箱体上
