Device for cutting and grinding, tensioning device and rotary tool with vibration damping

摘要

Device for cutting and grinding with a drive unit (10), with a drive spindle (14) having an axis, and with clamping elements (16, 24) for tensioning a grinding wheel, grinding or cutting (20) on the drive spindle (14), the clamping elements (16, 24) clamping surfaces (30, 32) and a central hole with which are seated on the drive spindle (14), the hole in the side of the clamping surfaces (30, 32) a collar (26) with a cylindrical outer side on which is seated the grinding wheel, grinding or cutting (20) with a hole of hub (28), and being provided between the grinding wheel , grinding or cutting (20) and the clamping elements (16, 24) means vibration dampers in the form of a coating (34) of elastic material on the clamping elements (16, 24), characterized in that the coating (34) elastic material is lifted around the do outer cylindrical collar (26).
