PURPOSE: To check the scratching of cut faces of a work piece, which occurs when a wire is pulled out, and enhance the profile irregularity by taking out the wire from the work piece in a way to pull it out after the work piece was washed with rinsing oil having a temperature over 30°C.
CONSTITUTION: Cutting is performed by sliding a line of processing wire 3 along the direction of the wire and supplying abrasive liquid to a work piece 1 and the sliding part of the wire 3. Next, the rinsing oil 5 inside a rinsing oil tank 20 is maintained over 30°C by a temperature adjusting mechanism consisting of an electric heater 23 and a temperature sensor 25. After washing the work piece 1 with the rinsing oil, the wire 3 is removed from the work piece 1 in a way to pull it out. As a result, the scratching of cut faces of the work piece 1, which occurs on the extraction of the wire 3, can be checked to improve its profile irregularity.
