The present invention relates to the field of sheet metal production and processing, and specifically to a CNC grinding device and processing method for sheet metal production, comprising: a base, a connection frame installed above the base, and a sieve plate installed in the connection frame. The present invention fixes the sheet metal above the sieve plate through a fixed roller, and the grinding disc is attached to the surface of the sheet metal under the continuous downward pressure of the fixed cylinder. At this time, the motor drives the grinding disc to grind the sheet metal and blows away the debris under the action of the turbofan, thereby protecting the surface of the sheet metal. During grinding and pressing, due to the buffer between the spring and the fixed roller, the grinding disc is prevented from being in hard contact with the sheet metal and causing excessive grinding. During the grinding process, due to the action of the fixed roller, the grinding disc can be moved for grinding, and the corresponding position of the fixed roller can be adjusted according to the size of the sheet metal. Through the above structure, the grinding processing efficiency can be improved while ensuring the surface grinding quality of the sheet metal.
