In recent years, it has become possible to adhere whetstone grains firmly to a fine wire by the electrodeposition process. This experiment tried to use such a tungsten wire (diameter, 0.1 and 0.5mm) as processed with diamond grains (grain mesh, 200) for electrolytic sawing. A 10mm thick steel die was used as a work.
The wire saw was set in the center of the nozzle jet stream of an electrolyte and was reciprocated at the constant feeding speed of the work. The results are as follows:
(1) When the feeding speed exceeds 0.46mm/min., the type of sawing process changes from the electro-chemical machining to the electrolytic grinding.
(2) As the Feeding speed increases, the uniformity of sawn groove width is improved.
The similar improvement can be made by decreasing the voltage and reciprocating frequency, especially at the low feeding speed.
(3) The maximun feeding speed obtained in this experiment is 0.79mm/min.
