Abstract
A method serves for cylindrical surface grinding of workpieces. A grinding wheel engages a workpiece which rotates in the opposite direction and is fed at a given feeding speed parallel to the axis of the workpiece. The grinding wheel rotates about an axis which is inclined at an angle relative to the axis of the workpiece. In order to achieve workpiece surfaces of low roughness at high machining speeds, in particular surfaces without spiral-shaped surface grooves, one first determines from the given surface roughness, by empirical means, a contact ratio serving as an auxiliary value whereafter the axial length of the first surface is determined and adjusted using a formula. The method is used within a range of values where workpiece diameters of 5 to 250 mm are encountered, the grinding wheel rotates at a speed of 100 to 300 m/s, the workpiece rotates at a circumferential speed of 65 to 200 m/s and the speed of the axial feed is between 150 to 2000 mm/min.
