    摘要: Auf Führungen (1) eines Gestells (2) ist ein Schlitten (3) in Vorschubrichtung (A) verschiebbar geführt. Der Schlitten (3) trägt ein Ultraschallbearbeitungsgerät (4) und wird durch einen ersten Zylinder (7) mit einer einstellbaren Kraft in Vorschub- richtung (A) belastet. Am Schlitten (3) ist ein Zylinder (15) befestigt, um den ein Seil (17) mit einer Schlaufe (16) von 360 Grad geschlungen ist. Das eine Ende (18) des Seils (17) ist durch eine vorgespannte Feder (20) gegen einen gehäusefesten Anschlag (21) vorbelastet. Das andere Ende (22) des Seiles (17) ist an der Kolbenstange (24) eines zweiten Zylinders (25) befestigt. Durch diesen zweiten Zylinder kann während der Bearbeitung das Werkzeug (5) vom Werkstück (6) abgehoben werden, unabhängig von der Schlittenposition. Nach dem Abheben setzt das Werkzeug (5) sanft wieder auf die erneuerte Schleifschicht auf.

    摘要: A method of trial cutting, wherein stopping and restarting of trial cutting work, repeated operations of trial cutting work on a desirable portion and correcting work for a processing program can be easily performed. By providing speed increasing and decreasing keys K3, K4 for continuously changing a main shaft rotation speed R1 and speed increasing and decreasing keys K1, K2 for continuously changing a tool feed speed R2 on CRT, MDI (4) of a numerically controlled machine, whereby a main shaft rotation speed R1 and a tool feed speed R2 can be freely changed regardless of whether or not a main shaft rotation speed R1 and a tool feed speed R2 are specified by a processing program in a RAM 3, and optimal main shaft rotation speed R1 and tool feed speed R2 are determined while the cutting work is performed on the basis of a processing profile given by the processing program in the RAM 3. Since there is no need for determining optimal cutting conditions by changing a main shaft rotation speed and a tool feed speed by correcting the processing program for each processing unlike the prior art, optimal cutting conditions can be easily obtained within a short period of time.

    摘要: The device enables to remove workpieces and workpiece supports from a conveyor track and to hold them against a working pressure by means of a socket (24), an elevator table (30) and a slide (32) arranged between the latter and which may be displaced by a drive member (34) from an end position to the other. At least one of the parts (24, 30, 32) is provided with a lifting surface (56, 58) each comprised of a section of the surface of the cylindrical body (52). The antagonist surfaces (60, 62) which cooperate with the lifting surfaces (56, 58) are formed of rotatingly mounted lifting rollers (40, 46) which are freed of the working pressure when the elevator table (30) is in the working position by means of offset support surfaces (38, 42, 50) of the socket (24), of the table (30) and of the slide (32). Said device is characterized by a small stroke of the slide (32), minimal friction forces, and by the fact that the extreme positions of the slide (32) need not be determined and accurately respected.

    摘要: A stop controller of a cutting tool which performs emergency stopping of a cutting tool during a cycle operation and returns the cutting tool to a cycle start position according to the present invention is provided with memory means (A, B) for storing a sequence operation program for returning the cutting tool to the cycle start position in accordance with a stop position at each stage of the cycle operation, discrimination means (3) for discriminating the step of the cycle operation at the time of stop, and program control means (2) for calling the sequence operation program in the memory means from the cycle program in accordance with the stop position corresponding to the discriminated cycle operation. The stop controller can return automatically the cutting tools through an optimum route using a sequence program for retreat in accordance with the operation interruption state at the time of emergency stop.
