When the diamond wire saw cutting the horizontal plane, the wire saw usually moves in a clockwise direction. According to the actual situation of the site, it can also move in the counterclockwise direction. When mining and cutting vertical surfaces, the wire rope moves from bottom to top. At this time, the cooling water is brought into the saw gap by the wire saw from bottom to top, the cooling water can increase the time in the saw gap due to gravity and improve the cooling effect of the wire rope. It also can facilitate the discharge of stone debris. If the wire rope adopts from top to bottom cutting movement, the powdered chips will be deposited downward into the cutting seam below, this will cause the blockage. But at present, there are also wire saw adopts from top to bottom movement, the sawing effect is also ideal. Once the wire rope is used, the cutting direction cannot be changed for each subsequent use. If the cutting direction is changed in the middle, the diamonds on the surface of the wire saw will fall off in large quantities. reducing the service life of the wire saw. In serious cases, a hardened skin will appear on the surface of the base metal layer on the bead. The wire rope cannot cut the stone and must be re-blade. In practice, it has been found that once this kind of crust produced by the wrong cutting direction of the beaded rope occurs, it takes a lot of time to sharpen it. It takes 5-6 times longer to grind the hard skin away with a firebrick than with a normal cutting edge.
