It is usual to support the workpiece by dead centers in high precision cylindrical grinding. The workpiece is rotated as a guide to the contacting parts between centers and center holes. Some experiments were performed on the roundness of ground cylindrical surface, the effect of roundness of the center holes and the mis-alignment of the centers. Furthermore, the ball center, which has been used in the precision instrumentation, was applied to the cylindrical grinding experiments. As a result, it becomes clear that the roundness of the center holes affects the roundness of the ground surface, especially with some mis-alignment between centers. The ground surface, in the side of tail stock, was more badly influenced. The out-of-roundness of the ground surface was within 0.5μm with ball center, while 1/10 of the out-of-roundness of the center holes with cone center. The ball center is vulnerable, so suitable lubrication was necessary.
