Abstract
Cutting-off wheel (1), in particular with a diameter above 500 mm, which is provided laterally with steel sheets or steel grids (2) with a minimum thickness of 0.5 mm.
Claims19
A cutting-off wheel with a diameter above 500 mm, which can be clamped between clamping flanges, with a mixture of abrasive grain, binder and optionally fillers, which extends from the outer edge of the cutting-off wheel up to the central bore, the cutting-off wheel being provided laterally with steel sheets or steel grids, wherein the steel sheets or steel grids are housed flush in recesses in the side surfaces of the cutting-off wheel and have a minimum thickness of 0.5 mm and a radial extension exceeding the radial extension of the clamping flanges, wherein the steel sheets or steel grids are glued to the cutting-off wheel.
A process for producing a cutting-off wheel with a diameter above 500 mm, wherein a steel sheet or steel grid with a minimum thickness of 0.5 mm and with an extension exceeding the radial extension of at least two clamping flanges is laid onto a pressing plate, a mixture of abrasive grain, binder and optionally fillers is then applied and finally compacted, so that the steel sheet or steel grid is inserted flush into a side surface of the plate, wherein, upon compaction, a recess is formed into which the second steel sheet or steel grid is pressed, wherein the steel sheets or steel grids are provided with an epoxide adhesive before being pressed on the side of the plate facing the mixture of abrasive grain, binder and optionally fillers.
