Manufacturing of Green Ceramic Balls: Machine and Process

Abstract:

Ceramic balls are great application in high precision components such as hybrid bearings or hip prostheses where high performance is only achieved through close tolerances of form and dimension. Green machining is a critical step in the manufacturing of balls since the allowance removed and the surface finish achieved at the conclusion have a direct influence on the quality of the final product. The work aims to design a prototype for machining the green ball to Ø19 mm following the approach of mechanical design methodology. The concept consists of three wheels, two for drag with speed and direction of rotation variables to promote random orbital effect on the ball and a grinding wheel with track of silicon carbide #120 mesh. Spherical zirconia blanks were shaped by isostatic pressing at 200 MPa and machined in the manufactured prototype.
