An easy way to grind a cylindrical surface on a steel ball is to clean the steel ball and remove oil and impurities from its surface. Apply 502 glue evenly to the face of the simple clamp (see picture). The steel ball is placed on the rubber cone of the clamp after the glue is applied, and the force of about 5oN is rotated by hand for several weeks to make the thickness of the glue layer uniform, and the coaxiality of the outer circle and the spherical surface of the processing is ensured, and the application time is 1 min. The solid steel ball and the clamp are clamped into the chuck of the cylindrical grinding machine, and the right side is applied with a flat top tip to apply a force of about 5oN to the steel ball to avoid the insufficient bonding strength of the 502 glue.
