Claims
- 1. A method for trueing a grinding disk having an outer layer of diamond or cubic crystalline boron nitride during rotation thereof with a predetermined circumferential speed, comprising the steps of engaging said outer layer of said grinding disk with a driven but axially immovable diamond trueing roll so as to profile and true said layer; and directly engaging said outer layer of said grinding disk at a location spaced from said trueing roll with an additional separately driven trueing disk with an outer layer of ceramically or bakelitically bound silicon carbide or corundum, rotating with a relative peripheral speed of 0.5-1.0 meters per second relative to the peripheral speed of said grinding disk and continuously adapting itself to said profile of said grinding disk so as not to enter and alter said profile but to offset the binder relative to a working surface of the grains of said grinding disks.
- 2. The method as defined in claim 1, wherein the trueing of the grinding disk is performed with a relative speed between said trueing disk and said grinding disk of 0.5-0.6 meter per second.
- 3. A method as defined in claim 1, wherein said true disk is pressed with a constant force against said outer layer of said grinding disk.
- 4. A method as defined in claim 1, wherein said trueing of said grinding disk by said trueing roll and said trueing disk is performed while said grinding disk grinds a workpiece.
