The two are respectively fixed at the front ends of two telescopic rods which are arranged in parallel, and the distance between the two telescopic rods can be adjusted according to the thickness condition of a workpiece to be processed; according to the length condition of the workpiece to be processed, the length of the telescopic rod can be adjusted, and the double-sided grinding of various surfaces can be easily realized by matching with the feeding motion of the workbench. Besides the common advantages of double-sided grinding (high efficiency), the application range of the double-sided grinding machine is greatly improved.

Chinese patent CN210524642U discloses a double-sided grinding machine for ceramic processing, which requires a person to apply an external force to rotate a grinding disc, and the grinding disc processing is rigid processing, and can only be used for processing a plane, and is difficult to be used for processing surfaces with other shapes.

At present, the double-sided grinding technology is mainly applied to the processing of plane type workpieces, and along with the development and the requirement of precision processing, some non-plane type workpieces also gradually need to carry out grinding processing on an inner surface and an outer surface. The utility model discloses then comply with this production reality, realized the two-sided simultaneous grinding on multiple surface to have advantages such as efficient, precision height, simple operation.
