Abstract (en)

[origin: EP0257194A2] The internal grinding spindle can be swivelled automatically in the vertical plane. Consequently, the necessary angular position during thread grinding can be set and, in the horizontal position, the internal grinding spindle can be taken past a profile roller, arranged laterally on the headstock, for truing. <IMAGE>
