An automatic machine for arrissing the edges of glass sheets, comprising devices that allow to work glass sheets by way of rigid tools, such as diamond grinding wheels, by acting simultaneously on the two face edges along the perimeter of the sheet. The machine comprises at least one working head, provided with a tool with a probe and feedback circuits for grinding symmetrically the glass sheet and following the perimetric profile of the sheet by a combined action of moving the glass sheet and at least one working head.
