An abrasive product is formed, in a blank making machine, into a layer forming a blank including at least abrasive grains. The layer is then set atop on at least another blank making machine, an assembly line along which successive posts are provided at the site whereof the elements designed to form the grinder are set on top of one another to form a stack, a station for heating the stack, and at least a pressing machine to compress the heated stack. An embodiment need not include the heating station. The grinder is a thin grinder that can include at least a reinforcing layer pierced with a hole wherein the abrasive product is distributed. The process is useful for making grinders for parting, machining, or pumicing.

Method and installation for making abrasive grinders and grinder obtained by said method

In a depressed-center abrasive wheel assembly a reinforcement layer of polygonal shape is located between a front face of the abrasive wheel and a front flange. The reinforcement layer is dimensioned to entirely cover the depressed center portion of the wheel. An example of polygonal reinforcement layer has a hexagonal shape and is made of fiberglass cloth. A polygonal shape reinforcement layer can also be employed between the front flange and the front face in an abrasive flat wheel assembly that employs a wheel without internal reinforcement.

Reinforced abrasive wheels

An abrasive product is formed, in a blanket making machine, into a layer forming a blank including at least abrasive grains. The layer is then set atop on at least another material layer and assembled thereto. The installation includes, besides at least a blank making machine, an assembly line along which successive posts are provided at the site whereof the elements designed to form the grinder are set on top of one another to form a stack, a station for heating the stack, and at least a pressing machine to compress the heated stack. An embodiment need not include the heating station. The grinder is a thin grinder that can include at least a reinforcing layer pierced with a hole wherein the abrasive product is distributed. The process is useful for making grinders for parting, machining, or pumicing.
