A grinding unit especially adapted for use for grinding with a robot and in automatic machines. The unit is designed with a grinding wheel on an axially displaceable shaft, which is urged in a direction towards a surface to be ground by a spring. The grinding pressure is determined by this spring and the position of the grinding wheel is determined by the level of the grinding surface. The mass of the parts which are displaced under the influence of the grinding pressure can be made small. Only the grinding wheel, the shaft and a member, which is directly connected to said shaft, are displaced. Therefore, the grinding pressure is influenced only to an insignificant extent when changing the orientation of the grinding unit. |
