Factors affecting the machining accuracy of cylindrical grinders.
1. The height error of the grinding head, headstock, and tailstock will cause the centerline of the headstock and tailstock to deviate from the axis of the grinding wheel spindle in space, resulting in a hyperbolic surface on the surface of the workpiece being ground.
2. When there is a parallelism error between the centerline of the headstock and tailstock and the axis of the grinding head spindle in the horizontal plane, the shape of the workpiece ground by the external cylindrical grinder will be a cone.
3. The perpendicularity error of the grinding head relative to the guide rail of the cylindrical grinder will cause the spindle axis to deviate from the centerline of the headstock and tailstock.
