Pallet with adjustable anchorage system for equipping the clamping fixture of a rough piece to be machined with machine tools

The pallet includes one or more supporting faces, each of which is provided with an anchorage system for equipping the clamping fixture of a rough piece to be machined with machine tools. Each supporting face has one or more anchorage members for components of said clamping fixture. Each anchorage members may be adjusted as to height and as to angular orientation and is connected with a supply of fluid. Said adjustment is carried out by screwing and unscrewing said anchorage members in corresponding appropriately threaded holes in the supporting faces of the pallet.

Method of reducing the wear of the electrode in machine tools using electro-erosion

Method of reducing the wear of the electrode in machine tools using electro-erosion. There is provided a circuit with different stages of power; the tension of the first can be superior, facilitating the ionization of the channel and reducing the delay of ionization. A circuit detects the ionization and sets going some programmable counters which count impulses proceeding from the time base, the frequency of which is superior to that of the work impulses; when the preselected count has been reached, the circuit emits a signal of conduction to the following power stage, which supplies an impulse of stronger current, with a certain delay with respect to the first, and so on. By succeeding in establishing the working current in a spaced-out form, it can materialize in one or more jumps so that the currents selected continue to increase progressively, varying at will the shape of the rising side of the current impulse. This method reduces the wear of the electrode by at least about 50%.

Tool exchanger for programmed-controlled machine tools

A tool exchanger for programmed machine tools includes a device for the conveyance of selected tools between a tool room and a main spindle of the machine tool and with two grip devices moving along a prescribed rotation angle and arranged in a carrier support mounted to the conveyance device and able to rotate between an alternate position and at least one standby position. In order to achieve faster exchange operations of the tools in a horizontal and vertical machining spindle, the drives to open and close both tool grips are activated at the same time. The support mounted includes a locking device which blocks the tool grip to standby position in its closed condition.

Bar-pusher actuation device for bar feeders applied to machine tools

The bar-pusher actuation device for bar feeders applied to machine tools includes a linear actuator composed of a chain with which the bar-pusher is associated and which is closed around a pair of fixed pinions and a pair of gearwheels which are movable with respect to the pinions. The pair of gearwheels is mounted on a slider which is slidable parallel to the direction of advancement of the bar. The slider is actuated by a jack adapted to perform a reciprocating stroke which substantially corresponds to the length of the portion of bar to be machined.
