A hollow inner slide is connected in the control slide 64.

A pawl is mounted axially displaceably in the gearwheel 86 to be machined with a corresponding template, which at its free end represents a conical workpiece. The layer 80 represents a shaped head 102. A layer between the curve that remains after the preceding processing disk 75 and the pawl 101 remains of the work piece .

The stop member 76 in FIGS. 4 to 6 is a hammer screw 90 of the stop piece 77. This shows, of which FIG. FIG. 4 is a representation of the type of the slide in a rich exploded diagram. On the slide 61 the direction to the tool are interrupted and the work two bearings 81 and 81 'are attached, in which a shaft tool 1' starts on the slide 61 on the workpiece 78 '82 is rotatably mounted, the stop disk 83, (Fig. 3 ) to remove a chip, which is determined by the thickness of a cam disk 84, a ratchet disk 85, a 30 of the layer 111 to be machined. At gear 86, a lifting disk 87, the cam disk of the movement of the device according to the invention 75 and a handwheel 88 carries. Of this, the manure-receiving rotary slide of the lathe disc 84 and the gear 86 rotatably on the ne along the workpiece 78 'is the stop shaft, while the discs 83, 85 and 75 screw 89 so long on the stop screw 90, and the handwheel 88 is connected to the shaft in a rotationally fixed manner until the buttons 70 are at the set finishing depth. The lifting disk 87 is in a rotationally fixed position on the template when the tool has reached the housing 109 and is in its rotational position as desired, point A of the workpiece. In that adjustable. now takes over the following area of processing

While together with a stop screw 90, which moves the carriage 61 back into its rest position Fixed stop 45 attached to the slide track 62 pushes the rack 105 onto the raised section of the piece 77 is screwed in. The cam disk 84 is on the cam 107 and rotates the gear 86 along with it the stop disk 83 by a holding counterclockwise under tension of the screw 91 connected in a bore 92 to torsion spring 108.

The long electromagnet 22 ', 23 (Fig. 2) is used. This Hole 110 in the disc 102 is designed so that the switch is from one of the stop screws 89 to to operate indirectly at the end of the rotary movement of the gear 86 in the 15 89 '"of the stop disk 83, Clockwise (FIG. 4) the pawl 101 from the council, including a special design of the stop members control wheel 85 against the action of the spring 103 is required. These then consist of a BoI-lifted will. This lifting is of no importance, zen 123, which has a protrusion on its underside as long as the pawl 97 has in one of the teeth 98 of the ratchet 124 and in its end face a screw pin wheel 85 intervenes. If, however, the pawl 97 20 zen 125 is screwed in, its position is countered the locking member 94 'secures in its retracted nut 126.

Held in position, the ratchet wheel 85 is no longer "one" with the bolt 123 and the screw bolt locked against turning. As soon as the pawl 101 125 is also the actuating pin 128 working together because of the lifting of the ratchet wheel 85 by counter to the force of a spring 129 in one by one the lifting disk 87 does not lock into any of the teeth 100 any longer in an actuating member 130 which can be rotated on an axis 131, can bar the shaft 82 through the torsion spring 108 and against stepping outwards through a Unhindered returned to its original position, cross pin 132 secured.

If the number of ratchet teeth 98 is greater than 128 by one, which means that the number of stop screws 89 and the number member 130 is axially displaced in the rotatable actuator without pivoting this to the ratchet teeth 100 by one greater than this number. Corresponds to e.g. B. the stop bolt 123 (four stop screws 89, five ratchet teeth 98, the stop bolt 89, the carriage begins and six ratchet teeth 100), so there is a 45 course of the button 70 on the template 7t correspond-intermediate position of the shaft 82, in which none of the ways to retract a little as soon as the tool Γ impact screws 89 with the stop screw 90 has reached point A on the workpiece 78 '. Would work together. Since the cam 75 at the end of the machining of the layer 111, the advance of the machining of the layers 111 to 114 lies the jump 124 on the pin 128 and swivels this so-held auxiliary slide 32 in a position in which 50 like the swiveling actuating member 130 opposite rather the chamber 39 with the pressure medium source 27 is connected to the force of the spring 136. When the actuator is pivoted, the switch 122 is actuated in the intermediate position of the auxiliary member 130, the slide 32 is released, whereby, as already done, a pulse is sent to the Magnet 22 ', 23 leads to lifting, the control slide in its in Fig.2 the tool 1' from the workpiece 78 is. The posed situation returns. In spite of the fact that the carriage of the copying device is in contact, the feeler element 70 moves automatically against the template 71 and therefore moves back. The slide receiving the copier device then moves by a preset amount in the direction of the slide of the lathe through the end to the workpiece 78 in order to switch the layer 81 back into its rotational position, also controlled by a switch, to machine. Only after the removal of the so-called `` Here '' can the stop member 76 go into its 60 ters of the carriage 61, as described above, back to the starting position, in which for the purpose of machining the layer 112, the stop member 76 goes back to the starting position, in which one is employed again for the purpose of machining the layer 112 the new workpiece. During the next work cycle, a stop bolt corresponding to the screw 89 again works together with a stop screw 90, hammer screw 89. There can be an additional work 123 in operative connection with the switch 122, whereby operation can be switched on, in that the tool 65 the projection attached to the stop bolt acts on the workpiece 78 at a distance from the layer 80 the switch as soon as the tool \ edited along its entire length.

When machining the layer 114, the projection 124 can be arranged on the bolt 123 that the carriage 61 return to its rest position

A corresponding arrangement of the projection 124 results for the finishing of the workpiece 78 ', the tool beginning to lift off the workpiece 7 when it reaches the point E. In the last two cases, the arrangement of the screw bolt 125 and the counter nut 126 can be dispensed with, since here the T; ster 70 takes over the leadership of the carriage 61.
