Abstract (en)
[origin: EP0358137A2] In a method for manufacturing grinding devices (26) using a mould (1), in which method the grinding compound (24) consists of a binding agent mixed with abrasive grains (27), the profiled surface (18) of the casting chamber (9, 10) has an open structure. Thus the abrasive grains (27) adjacent to the profiled surface (18) assume a random position after the solidifying in the binding agent, their sharp corners and edges preferably being orientated at right angles to the grinding surface. The grinding device (26) is thus immediately ready for use without the uppermost layer first having to be removed by dressing. <IMAGE>
