   und   Abgehens der Schleifsupporte eine Drehung zwischen Werkzeng und Werkstück um dessen Längsachse erfolgen. Das   ges@hieht hier dadurch, dass der Schlitten 2 samt   dem   Bock   und den auf und ab gehenden Schleifsupporten um das stehenbleibende Werkstück entsprechend der Steigung der Schraubenwindungen kreis nd herumgeführt wird. 



   Die Schaltbewegung des Werkstückes um einen Zahn wird, wie oben bereits angeführt, unabhängig von der Drehung des Kreisschlittens 2 am Ende des lotrechten Supportllubes durch   Wechselräder   vorgenommen, welche der Zahnteilung genau entsprechen. 



   Es steht beim Schleifen der Windungen das Werkstück still und nur beim Schalten auf den nächsten Zahn wird es um eine Zahnteilung gedreht. 



   Die kreisförmige Bewegung des Schlittens 2 mit gleichzeitiger Auf- und Abbewegung der Schleifsupporte 4 und 5 wird nun auf folgende Weise erreicht : Die Hauptantriebswelle, auf welcher am vorderen Ende fest aufgekeilt der konische Trieb 16 sitzt, wird durch eine lose laufende Riemenscheibe 15 unter   Vermittlung   eines lose laufenden Wechselgetriebes aus Kegelrädern angetrieben, von welchen das eine Rad 17 mit der Riemenscheibe verbunden ist.

   Eine auf der Antriebswelle zwischen den Rädern 17, 18 des Wechselgetriebes auf Keil verschiebbar   gelag   ite Kupplungsmuffe 19, die durch Winkelhebel   20 nach   links und rechts verschoben werden

   and removal of the grinding supports, a rotation between the tool and the workpiece about its longitudinal axis takes place. This is done here in that the carriage 2 together with the trestle and the up and down grinding supports are guided around the stationary workpiece according to the pitch of the screw turns.



   As already mentioned above, the switching movement of the workpiece around a tooth is carried out independently of the rotation of the circular slide 2 at the end of the vertical support hub by means of change gears which exactly correspond to the tooth pitch.



   The workpiece stands still while the coils are being ground and it is only rotated by one tooth pitch when switching to the next tooth.



   The circular movement of the carriage 2 with simultaneous up and down movement of the grinding supports 4 and 5 is now achieved in the following way: Loosely running change gear driven from bevel gears, one of which wheel 17 is connected to the pulley.

   One on the drive shaft between the wheels 17, 18 of the change gear on wedge slidable Gelag ite coupling sleeve 19, which are moved by angle lever 20 to the left and right

   These drives are designed as follows:
