Factors affecting machining accuracy of cylindrical grinder
1. The influence of the equal height of grinding head, headstock and tailstock on the dimensional accuracy of workpiece. The equal height error of grinding head, headstock and tailstock will make the center line of headstock and tailstock deviate from the axis of grinding wheel spindle in space. At this time, the workpiece surface will be a hyperboloid. grinding machine 2. The influence of the parallelism error of the axis of the grinding head spindle in the horizontal plane on the dimensional accuracy of the workpiece is analyzed. When this error occurs, the shape of the workpiece produced by the CNC cylindrical grinder will be a cone, that is, the grinding wheel grinds at an angle, and there are spiral grinding lines on the surface. Grinding Machine, Cnc Lathe, Sawing Machine 3. The influence of Perpendicularity Error of grinding head movement relative to machine tool guide rail on machining accuracy is analyzed. The final result of this error is that the axis of the
