However, the timing of heat treatment can vary when using a thread ground ball screw. This is because thread grinding allows the thread to be cut even after heat treating, it is preferred that heat treatment is performed prior to grinding, to ensure that the sizes and lead accuracy will not change due to the heat treatment.
