The crossbeam assembly 5 is used to support the grinding mechanism 2.

[0029] Working principle: In use, firstly, the mold to be processed is fixed on the surface of the mounting plate 34 using positioning blocks. The height of the mounting plate 34 can be adjusted by activating the lifting telescopic rod 31, allowing the mounting plate 34 to move the workpiece up and down to adjust its position. Activating the motor inside the bottom shell 321 drives the inner transverse screw, causing the pushing mechanism 33 to be pushed by the locking shell 322 inside the base component 32, allowing the mounting plate 34 to be moved laterally to adjust its position. Activating the motor inside the pushing mechanism 33 causes the longitudinal screw to rotate, moving the mounting plate 34 longitudinally, thus adjusting the position of the fixed workpiece. Adjustments are made to the horizontal, vertical, and height dimensions to allow the workpiece to cooperate with the grinding mechanism 2 for planar machining. When an inclined surface needs to be machined, the motor inside the starter frame 4 drives the positioning gear 42 to rotate, which in turn pushes the crossbeam assembly 5, allowing the angle of the crossbeam assembly 5 to be adjusted. This enables the grinding mechanism 2 to grind the inclined surface. The motor inside the positioning plate 621 drives the gear 622 to rotate, allowing the angle adjustment mechanism 6 to adjust the angle of the grinding mechanism 2 inside the crossbeam assembly 5, enabling the grinding mechanism 2 to tilt and grind the inclined surface of the workpiece.
