The diameter of a grinding spindle is heavily dependent on the pitch angle. The greater the pitch angle, the lower the rigidity of the spindle and the lower the possible metal rate removal. This leads to higher cycle times. The trend towards ball screw nuts with a large pitch which makes grinding even less suitable as a machining technique.

Apr 06, 2016· The rolling and grinding processes produce different surface finishes. A rough surface finish is problematic in ball screw assemblies because it can result in higher friction and more wear on the load-carrying balls. The grinding process produces a very smooth surface finish, and in theory, the rolling process does as well.
Ball screw nuts change torque into thrust without rotating themselves. The ball bearings rotate instead and the nut housing remains radially static as it slides on the shaft. Ball screw nuts can be made from plastic or metal; the shaft of the ball screw is machined from steel.
