Abstract (en)
[origin: DE102005004038A1] The method involves using a grinding disc (3a) with grinding grains embedded in a plastics resin binding where the grains consist of more than 50 percent of diamond and less than 5 percent of Cr203. The plastics resin binding is a hot pressed phenol resin or polyimide binding. Independent claim describes device for grinding ceramic spheres (2) where the grinding disc has a plastics resin binding, such as a hot pressed phenol resin binding.
