Grinding arm for grinding of workpieces with an inner profile with a grinding wheel

Abstract

A grinding arm for grinding workpieces with an inner profile with a grinding wheel. The grinding arm has a tube-shaped base body with a longitudinal axis, in which the grinding wheel is supported at one axial end region. A first drive for the grinding wheel is arranged in its other axial end region. A first transmission system transmits the rotation from the first drive to the grinding wheel. In order to adjust arbitrary angles of inclination of the grinding wheel in the grinding arm, the grinding wheel is arranged on a grinding spindle driven by the first transmission system and rotating around an axis of rotation. The grinding spindle is supported in a carrier body arranged in the base body rotatable around an axis perpendicular to the longitudinal axis as well as perpendicular to the axis of rotation, wherein the axis of rotation and the axis intersect.
