CS256901B1 - The method of electroerosion of small-sized profiled surfaces and equipment to perform this process - Google Patents

Abstract

The solution concerns a method and a device for electroerosion manufacturing of profile surfaces of small dimensions. The solution eliminates the shortcomings of known methods, allows for the maintenance of a constant profile of the electrode-tool during the work, while achieving maximum productivity. The essence of the solution lies in the fact that immediately before the machining area, a wire electrode profiles and gives a shape that corresponds to the final profile of the machined surface. The device with the help of which this method is applied consists of a spindle assembly and a drive mounted on the base table. A longitudinally sliding table is also located on the base table, as well as a guide for adjusting the angle of the transversely sliding table and longitudinal and transverse supports, which are located on it. The device is characterized in that a basic mechanism is attached to the transverse support, which consists of a shaping guide rod and a shaping pressure rod, on both sides of which, in the direction of feeding the round wire electrodes and the profiled electrodes, guide elements are placed, the axes of which are parallel to the axes of the feeding coil of the round wire electrode and the receiving coil of the profiled electrode.
