[0002] As a mechanical processing equipment that uses grinding wheels as cutting tools, surface grinders are usually used to process workpieces that require high precision and high surface quality. The main function of the cross saddle in a surface grinder is to carry the workpiece and perform precise positioning and adjustment. Through the guide rails and positioning devices on the cross saddle, the workpiece can be positioned quickly and accurately, and the workpiece can always remain stable during the processing. In addition, the cross saddle can also realize the rotation and tilting of the workpiece to meet different processing requirements.
