Abstract
A rotary grinding tool includes a central core constructed concentrically with respect to rotary axis. Lamellae, which are made of support mesh or the like coated with grinding material, are fixed along the total length of their roots to the core and extend approximately in axial planes passing through the rotary axis. The case is provided with a shank or the like for fixing the tool to a rotary grind machine. In order to permit the use of such a grind tool also into the inside angle without impairing its usefulness for peripheral grinding and without additional outlay, the lamallae project steadily increasingly beyond at least one end face of the core with increasing distance from the rotary axis, starting from their respective roots secured in the core.
Claims12
A rotary peripheral grinding tool having a rotary axis, the tool comprising a central core positioned concentrically with respect to said rotary axis;
- means for peripheral grinding comprising lamellae having respective roots and made of support mesh coated with grinding material secured along the total length of said roots in said central core, and said lamellae extending radially outwardly from said core in axial planes passing through said rotary axis, said lamellae having a cylindrical outer contour, with outer longitudinal edges parallel to said rotary axis for enabling their use as peripheral grinding means in work-pieces having angled areas forming a non-obtuse inside angle, said lamellae further increasingly projecting axially beyond at least one axial end face of said core with increasing distance from said rotary axis starting from said respective roots fixed in said core, and means for securing the tool in a rotary grinding machine.
