    Spiralbohrerschleifmaschine.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 vorganges derart verdreht, dass das Gewicht o allmählich niedersinken kann und den nötigen Vorschub des Bohrers erzeugt. Hat man auf diese Weise eine Lippe des Bohrers geschliffen, und wird dieser im Bohrerhalter um seine Achse um   800 gedreht,   um die andere Lippe zu schleifen, so bewirkt die beim Schleifen der ersten Lippe erhaltene Endstellung der Schraube p, dass die zweite Lippe in genau dem gleichen Masse abgeschliffen wird wie die erste. 



   PATENT-ANSPRÜCHE :
1. Spiralbohrerschleifmaschine mit pendelndem   Träger   für den Bohrerhalter. dadurch   gekenn-   zeichnet, dass die den Andruck und Vorschub des Werkstückes besorgende Belastung des pendelnd angeordneten Werkstückträgers durch ein Gewicht bewirkt wird, das einen verstellbaren Anschlag (etwa eine Stellschraube) trägt, der in der Arbeitsstellung auf ein festes Widerlager aufzuruhen kommt und durch dessen Verstellung der Andruck und der Vorschub des Bohrers geregelt werden kann.

 EMI1.1
 

 <Desc / Clms Page number 2>

 The process is twisted in such a way that the weight o can gradually sink and generate the necessary feed of the drill. If one lip of the drill has been ground in this way and it is rotated around its axis by 800 in the drill holder in order to grind the other lip, the end position of the screw p obtained when grinding the first lip causes the second lip to be exactly ground to the same mass as the first.



   PATENT CLAIMS:
1. Twist drill grinding machine with oscillating support for the drill holder. characterized in that the load on the pendularly arranged workpiece carrier, which is responsible for the pressure and advance of the workpiece, is brought about by a weight that carries an adjustable stop (such as an adjusting screw) that comes to rest on a fixed abutment in the working position and by its adjustment the pressure and the feed of the drill can be regulated.

Claims (1)

2. Maschine nach Anspruch 1, dadurch gekennzeichnet, dass der die Einspannvorrichtung für das Werkstück tragende Arm des pendelnden Trägers in der Arbeitsstellung mehr oder minder lotrecht und der die Gpgenbelasturg tragende Arm mehr oder minder wagrecht stehen und die Gewichte aller Teile so ausgemittelt sind, dass die Ausrückstellung des Trägers, bei der die Einspannvorrichtung von der Schleifscheibe entfernt ist, eine Gleichgewichtslage bildet, aus der der Träger nicht ohne äussere Beeinflussung in die Arbeitsstellung zurückkehrt. EMI2.1 2. Machine according to claim 1, characterized in that the arm of the pendulum carrier carrying the jig for the workpiece is more or less perpendicular in the working position and the arm carrying the Gpgenhabenurg are more or less horizontal and the weights of all parts are averaged so that the disengagement of the carrier, in which the clamping device is removed from the grinding wheel, forms an equilibrium position from which the carrier does not return to the working position without external influence.
