Abstract
A new machine for shredding a scrap material such as waste paper, cutter disks for particular use in shredding machine and a method of making cutter disks are disclosed. The life of the cutter disks is markedly increased and the performance of the shredding machine is improved by spark-depositing a wear-resistant material on the peripheral surface and side surfaces of each cutter disk. A layer of the spark-deposit on the peripheral surface should preferably be greater in thickness and unevenness than a layer of the spark-deposit on the side surfaces.
