METHOD OF MANUFACTURING FIXED KNIFE OF ROTOR SHAVING HEAD OF ELECTRIC RAZOR Russian patent published in 1997 - IPC

FIELD: electrochemical machining. SUBSTANCE: after machining the shaving grate is treated by heat, outer side of the grate is ground, grooves are cut by electrochemical method as well as polishing and setting the inner side of the knife are then carried out. During cutting one of the electrodes are set in forced vibration and working pulses are supplied that synchronize the beginning of the pulse supply with the phase when the electrodes move toward each other. The rate of feeding of one of the electrodes is controlled by deflection of real voltage pulses from the reference ones. The reference pulses are defined for different stages of machining. EFFECT: enhanced efficiency. 4 dwg, 1 tbl
