When using the diamond wire saw to cut stone, only by using the diamond wire saw correctly can the maximum cutting efficiency and cutting life of the diamond wire saw be guaranteed and the cutting cost be reduced.
The methods for the correct use of diamond wire saws include: appropriate tension control, preloading of plastic injection diamond wire saws, connection methods for diamond wire saws, requirements for the alternate use of new and used diamond wire saws during the cutting process, requirements for the mixed use of new and used diamond wire saws, maintenance, repair of diamond wire saws, and the correct placement of cooling water.
Tensioning Force of Diamond Wire Saw
Because diamond wire saws are flexible cutting tools, appropriate tensioning forces must be applied to diamond wire saws during use to make them both rigid and flexible, in order to ensure their optimal cutting efficiency, best-cutting quality, and longest service life. The amount of tension applied to a diamond wire saw is related to some factors, such as the application of the diamond wire saw, service length, diamond wire saw structure, the diameters of the diamond beads and wire rope, and the length of the cutting surface.
When cutting stone slabs and special-shaped stone products, in order to ensure the good surface and shape quality of the cutting object, the relatively high stiffness of the diamond wire saw must be maintained during the cutting process, and the vibration of the diamond wire saw must be minimized.
Pre-loading Rotation of Diamond Wire Saw
Before connecting the plastic injection diamond wire saw into a closed cutting ring, it is necessary to apply pre-load rotation to the diamond wire saw before connecting. Because the diamond beads of the plastic injection diamond wire saw are fixed on the steel wire rope, if not pre-load rotation, only by the natural rotation of the steel wire rope, is not able to make the diamond wire saw in the cutting process to maintain the autorotation, the result will lead to diamond bead outer circle of a side always contact with the cutting surface, make the diamond bead single side excessive wear (also known as partial grinding), which will reduce the service life of the diamond rope saw. The function of pre-load rotation is to ensure that when cutting, the wire rope with diamond beads around its own axis non-stop rotation, so that diamond beads wear evenly.
For spring-loaded diamond wire saws, the diamond beads and wire rope can rotate between them, so there is no need to preload the rotation before connecting the spring-loaded diamond wire saw to the closed ring, which can also guarantee that the diamond beads can rotate freely during the cutting process, and there will be no eccentric wear of the diamond beads.
The number of revolutions of the diamond wire saw preload rotation is determined by the length of the diamond wire saw, and the degree of the old and new ones. In the case of new or almost new diamond wire saw, the number of lap joints of preload rotation can be appropriately reduced, so as to reduce the fatigue of the diamond wire saw after multiple uses, and the impact on the rotation capacity of the wire saw, and the number of turns of the preload rotation of the diamond wire saw used will be increased accordingly.
