PROBLEM TO BE SOLVED: To provide a wire saw processing method excellent in practicality by further improving. SOLUTION: In this wire saw processing device, a wire 7 is moved, and the wire 7 is pressed onto a material 1 to be machined while the material is rotated cutting the material. The revolving speed of the material 1 to be machined during the period of time from a starting time to a time when shallow grooves are formed over the outer circumferential surface of the material 1 to be machined, is made lower than its revolution speed later on. By this constitution, the wire 7 can be stably processed without shaking over the processed surface of the material when the processing is started. As the moving direction of the wire 7 is reversed, the rotational direction of the material 1 to be machine is reversed. Before the material 1 to be machined is cut off at its center portion, the rotation of the material 1 to be machined is suspended, and the moving wire 7 is pressed onto the material 1 to be machined in a state of the material 1 to be machine suspended in rotation to cut off the material 1 to be machined at its center portion. |
