Abstract
PURPOSE: To make the electrolytic polishing amount of whole wire rod uniform, by dipping plural short length tungsten wire rods in electrolytic liquid and automatically controlling the resistance value of variable resistor corresponding to the deviation of preliminary set up standard value, measuring the current value turned on each wire rod, after connecting the above rods with the same power source in parallel through each variable resistor.
CONSTITUTION: A fixed length of the plural wire rods 4 is dipped in the electrolyte (a) and the rods 4 are connected in parallel with the anode side of the same power source 3 through each variable resistor 5. Each current turned on each wire rod, is measured by the ammeter 6 and measured value converted in digital value by the A/D converter 7, is sent to CPU 8 and is memorized in the memory device 9 individually. Then, memorized values are compared with the standard current value set up in the memory device 10 preliminary and control signal is sent to corresponding variable resistor with the quantity of deviation is exceeded allowable limit and then, the resistance value is controlled automatically by the signal converted in analogue signal by the A/D converter 11.
