Because the wire saw is a flexible cutting tool, proper tension must be applied to it when using it to make the wire saw a rigid and flexible cutting tool to ensure the best cutting efficiency, the best cutting quality and the longest service life. The amount of tension applied to the wire saw is related to these factors, such as the purpose of the wire saw, the length of the cutting surface, the length of the wire saw, the structure of the wire saw, the diameter of the bead or the wire rope, etc. When the flexible wire saw is cutting slabs or special-shaped products, in order to ensure that the cutting surface has a good surface quality and shape, the wire saw must maintain a relatively high rigidity during cutting, and minimize the jitter of the wire rope. At this time, a relatively large tension should be applied to the wire saw. The length of the cutting surface of the wire saw used in trimming machines, special-shaped wire saws and other fixed wire saws is generally 1.2-4 meters, the length of the wire rope is 16-24 meters, the diameter of wire saw is 8.7-9.2mm, the diameter of the steel wire rope is 3.5-4.8mm. The wire saw is plastic structure, the tension acting on the wire saws is generally around 3000-6000N. When mining or trimming blocks, although the cutting area is large and the used wire saw is long, the surface quality of the cutting surface is relatively low. During the cutting process, with the cutting process the cutting area is gradually reduced, and the length of the wire saw is constantly changing due to the reduction of the cutting surface and the adjustment of the wire saw machine operating position. Therefore, in mining or block trimming, even if use beads with a diameter of 11-12mm and a wire saw with a diameter of 4.9mm, can also use relatively low tension to control.
