The invention belongs to the technical field of 
grinding machines, and particularly relates to a 
grinding head 
movable type horizontal shaft circular truncated cone plane 
grinding machine. The technical problem that the design is unreasonable and other technical problems in the prior art are solved. The grinding head 
movable type horizontal shaft circular truncated cone plane grinding 
machine comprises a 
fixed frame, a rotatable working platform which can fix a workpiece and enable the workpiece to rotate in the circumferential direction is arranged on one side of the 
fixed frame, a horizontally-
moving frame is arranged on the other side of the 
fixed frame, a horizontally-moving drive mechanism which can drive the horizontally-
moving frame to horizontally move back and forth is arranged on the fixed frame, a lifting frame is arranged on the horizontally-
moving frame, a lifting drive mechanism which can drive the lifting frame to ascend and descend is arranged on the horizontally-moving frame, and a grinding 
assembly which can 
grind the workpiece is arranged on the lifting frame. The grinding head 
movable type horizontal shaft circular truncated cone plane grinding 
machine has the beneficial effects that the structure is compact, the size is reduced, and operation is more convenient; a high-speed rotating plane is adopted, and the 
machining precision is higher; and a cast hard rail is adopted and can absorb shaking produced during running of equipment, and the 
grinding wheel feeding precision is improved.
