Improved Thread Grinding Process for Ball Screws

The ultimate in smooth running.

As part of the on-going improvement of our product designs and production processes, Steinmeyer has implemented an optimized thread grinding process for our ball screw shafts.  By optimizing the process parameters and improving the supply of cooling lubricants, a much finer surface finish can be achieved during grinding.

As shown in the magnified images below, a clear improvement is achieved in the surface topography of the shaft threads.  Our testing has shown that this new thread grinding process improves the lifetime and results in much smoother running behavior.
