 zum Glätten vorzuschieben, wenn immer es erfordert wird. Für die Glättarbeit ist besonders   Arkansasstein   geeignet. Der Werktisch 24 (der in Fig. 1 in punktierten Linien dargestellt ist) kann eine geradlinige, hin und her gehende Bewegung in Längsrichtung der Maschine in einem Rahmen 26 ausführen, welcher sich seinerseits in Querrichtung zur Maschine geradlinig hin und her bewegen kann, so dass also die Bewegung dieser beiden Teile rechtwinklig zueinander ist.

   Da die Seiten des Loches 37 stets parallel zu den Richtungen der vorgenannten Hin und Herbewegungen in Längs-und Querrichtung sein müssen, muss die Büchse   34,   welche, wie oben auseinandergesetzt, in fester Verbindung mit dem Spannfutter 29 und Block 36 ist, in dem Werkstückhalter 10 in der besonderen, hiefür notwendigen Stellung festgelegt werden. In der dargestellten Anordnung dient der Eingriff der Schraube 35 in den Schlitz 121 zur Erfüllung dieses Erfordernisses.

 to advance for smoothing whenever required. Arkansas stone is particularly suitable for smoothing. The work table 24 (which is shown in Fig. 1 in dotted lines) can perform a straight, reciprocating movement in the longitudinal direction of the machine in a frame 26, which in turn can move straight back and forth in the transverse direction of the machine, so that so the movement of these two parts is at right angles to each other.

   Since the sides of the hole 37 must always be parallel to the directions of the aforementioned reciprocating movements in the longitudinal and transverse directions, the sleeve 34, which, as explained above, is in fixed connection with the chuck 29 and block 36, must be in the workpiece holder 10 in the special position required for this. In the arrangement shown, the engagement of the screw 35 in the slot 121 serves to meet this requirement.

Claims

PATENT CLAIM: Workpiece holder for engraving machines or the like, characterized in that a two-part block (36) serving to hold the workpiece to be engraved is fitted in a chuck (29), which is covered on its outer side by a hardened protective disk (39) and in a threaded hole of the chuck a threaded bolt (42) is adjustable, which is used to grind the workpiece and smooth its surface to be engraved something from the chuck (29) respectively. from the hardened protective disk (39).
