The invention belongs to the technical field of plane grinding, particularly relates to plane grinding equipment with a rotating mechanism. The plane grinding equipment aims at solving the problems that in the using process of an existing plane grinding device, due to the fact that a workpiece at the upper end of a circular workbench cannot rotate, consequently, the workpiece cannot be effectivelyground, and the workpiece is inconvenient to fix. Based on the following scheme, the plane grinding equipment comprises a workbench and a top vertical plate of the workbench, a vertical cavity is formed in the vertical plate, a lifting structure is arranged in the vertical cavity, a sliding block is connected to the lifting structure, a transverse plate is fixedly installed on the sliding block,a grinding motor is installed at the bottom of the transverse plate in a sliding mode, a grinding head is connected to the grinding motor, an adjusting mechanism is connected to the transverse plate,the adjusting mechanism is connected with the grinding motor, a metal pipe is rotationally connected to the workbench, and a disc box is fixedly installed at the top of the metal pipe. The plane grinding equipment is convenient to operate, a workpiece is conveniently fixed, meanwhile, the workpiece can be driven to rotate, grinding is convenient, and therefore, the grinding efficiency is improved.
