Finish hard turning techniques are enjoying ever greater popularity in the metal-processing industry. It shortens processing time and increases flexibility. The hard turning process has advantages over cyclindrical grinding in particular for workpieces with complex contours. Some workpiece examples are ball screw nuts or threaded spindles. Want to [...] Read more..

Finish hard turning technology is world wide used to process hardened steel grades (to 68 HRC) in the submicron range. It drastically reduces the cycle times for complex workpieces when compared to cylindrical grinding, while maintaining accuracy. This article takes a look at the differences between hard turning and grinding technology. Want to [...] Read more..

Higher productivity, shorter cycle times and smaller production runs are playing an increasing role in the industry. Production plants are required to absorb the development capacity of their suppliers.  A German machining company has been using hard turning machines  for the machining of ball screw nuts for years.
