Thereby, the tool B can be displaced in the y-axis, or the γ-axis, and the z-axis direction with respect to the workpiece a to achieve the purpose of processing. However, since the main shaft base 15 is suspended in the half-air in the direction of the y-axis, the main shaft base 15 tends to be deformed due to its own weight, the components of the load, and the gravity of the earth, resulting in the spindle seat 15 # The center line is not perpendicular to the second shaft seat 14, so that the workpiece Α and the tool Β also produce a perpendicularity error, and the image processing accuracy is severe.

The novel spindle support control module includes a displacement sensing , a force hydraulic cylinder, a pipeline, a pressure sensor, and a central control unit. The displacement sensing n is used to detect the displacement of the spindle holder relative to the carrier. The tension cylinder has a rod body fixed to the spindle seat and adjacent to the first end portion of the spindle seat, and a rod extending along the cylinder body, the rod is fixed at one end to the spindle seat and adjacent to the spindle seat - Second end. The conduit transfers fluid to the cylinder of the tension cylinder such that the second end of the spindle mount flexes relative to the tension rod between a first position and a second position that are offset from the axis. The pressure sensor is configured to detect a fluid pressure acting on the tension cylinder, and the central control unit is electrically connected to the displacement sensor and the pressure sensor, and determines a preset pressure value range according to the displacement amount.
