摘要：
1. A process for the manufacture of multi-layer grinding discs, in particular multi-layer cutting-off and rough-working discs for free-hand grinding, in which mixtures of abrasive grain, bonding agents and, if necessary, fillers and, if necessary, reinforcements, are introduced into a mould in layers with at least one layer of interposed vibration-absorbing materials, the mixtures are compressed to form a moulded blank, and the resulting moulded blank is cured, characterized in that the layer or layers of vibration-absorbing material is/are incorporated in the mould in the form of a fine-grained, pourable powder and/or granules.
