- the raw stone 10 to be cut is usually a raw stone such as marble or granite, and any kind of raw stone can be cut.
- Conventional general multi-leaf stone cutting machine is a machine for processing stone in the form of a plate by combining a plurality of diamond cutting tools for cutting stone and making them rotate or move left and right.
- This conventional stone cutting method has a large amount of stone loss, and it is easy to cause environmental pollution problems due to excessive sludge generation.
- the thread saw when the thread saw is operated with a little excessive pressure, the thread saw opens or twists. That is, in the prior art, when a diamond tip is attached to a long steel plate, it rotates, descends, and cuts in a horizontal direction, the tension required for this is insufficient, causing widening or twisting, making it impossible to produce a good quality plate.
- the vertical reciprocating motion of the thread saw 110 enables cutting by the thread saw 110 as the rotational motion of a motor (not shown) is changed into vertical reciprocating motion by the crank mechanism 140 installed on the stone cutting machine.
- the filament saw 110 repeats the swing motion from top to bottom, and at the same time, as the raw stone 10 advances minutely in the direction of the filament saw 110, the filament saw 110 Let this stone be cut. At this time, it is desirable that the advancing speed of the stone be approximately 4m for 24 hours (approximately 2.8mm advancing speed per minute).
- the movement of the raw stone is performed by the stone moving device 130, and the stone moving device 130 may normally use a moving roller, but a moving mechanism of the same shape as a bogie is also possible and can transport heavy stones. If there is a device, there is no restriction on the type.
- FIG 2 is a view showing the movement direction of the thread saw 110 according to another embodiment of the present invention.
- the direction of movement of the thread saw 110 may be set differently in addition to the vertical reciprocating motion of repeatedly moving up and down as shown in FIG. 1 .
- the thread saw is directed from top to bottom to cut a part of the stone, then moved in a parallelogram shape in the order of 2 3 4 to return to the original position, and then cut from top to bottom again.
- a saw can be operated.
- the thread saw 110 or the cutting tip 120 that comes into contact with the stone always comes into contact only from top to bottom.
- the advantage of this method is that it can minimize the scattering of sludge during stone cutting. Because, in order to prevent the scattering of rock particles at the work site, water is usually sprayed downward from the top of the stone when cutting the stone. because it can be
- FIG 3 is a view from above of a stone thread cutting machine in which a plurality of thread saws 110 according to an embodiment of the present invention are coupled to the thread saw support 100 and mounted.
