Abstract
Description
The present invention relates to a diamond endless wire rope saw and a method of manufacturing the same. More specifically, it is very excellent in durability, such as the bonding strength of the beads and the tensile strength of the rope, and the cutting width is usually about 0.2 to 1.5 mm The present invention relates to a method for producing a diamond endless wire rope saw having a low loss and precision cutting.
Diamond wire saws are generally string-shaped saws, which can provide many advantages over traditional cutting tools. For example, circular saws and the like can cut almost any thickness of structure while the wire saw is limited to a cutting depth below the saw blade radius.
These wire saws are classified into diamond electrodeless wire saws that do not bond both ends of the wires and diamond endless wire saws that bind both ends of the wire and bind in an endless form.
Diamond Electrodeposition Wire A structure in which diamond is electrodeposited or attached to a surface of a single strand of wire rather than a wire in the form of a wire. As a related art, Patent Document 1 discloses a super-polishing wire saw having a plurality of each coated diamond attached to a wire with an organic binder and manufactured to a diameter of less than 0.5 mm.
However, this diamond electrodeposition wire saw has an advantage of having a diameter of 0.5 mm or less, but because it is a single wire rather than a rope type, a wire saw having a length of at least 5 km is wound in a reel form to unwind and wind it. Due to its weakness and durability, the wire breaks frequently during use and the service life is very short, and the wires rise due to the roughness of the diamond electrodeposited on the wire surface during repeated winding and unwinding of the reel. The burning phenomenon occurs and it is very difficult to adjust the tension of the wire, so that the wire is frequently broken, and the movable equipment is very expensive.
On the other hand, the diamond endless wire rope saw, as shown in Figure 1, cylindrical with a synthetic resin, such as polyurethane in a state in which the
Typically, such diamond endless wire rope saws have a diameter of at least 2 mm that allows beads to adhere to the wire rope by means of synthetic resin. That is, in the molding method by the synthetic resin, the beads could not be fixed to the wire rope having a diameter of 2 mm or less. By the way, when the diameter of the wire rope is large, the loss of the cutting object (raw material) is large and the cutting precision is inferior. In particular, when cutting an ingot of a silicon wafer, which is an expensive cutting object, not only the production cost increases but also a considerable time for cutting, and in addition, many silicon slurries are generated, which is disadvantageous for the environment. There is this.

According to the present invention, the adhesive 500 is preferably an anaerobic adhesive. The anaerobic adhesive is a liquid chemical whose main component is methacrylate, and when placed in an air free place, a chemical reaction starts and solidifies. In the process of solidification, the adhesive force and the sealing force is generated to act as an adhesive. Usually used for the adhesion of metals and metal components, metal ions serve as a catalyst to promote the chemical reaction of anaerobic bonds. The rate of hardening varies depending on the nature of the metal, and when used for metals that play a good role in catalysts such as brass and bronze, the initial rate of curing is less than 10 minutes. Slower than that
In general, in the case of the iron material used a lot, the initial curing time is about 20 to 30 minutes because it serves as a medium catalyst. Since the metal component simply serves as a catalyst, there is no problem of melting or deformation.
As it is an anaerobic product, chemical reactions do not start when in contact with air. When air contact is interrupted, a chemical reaction begins, turning the liquid product into a solid state. In this process, adhesiveness and sealing properties are exhibited. Placing anaerobic products on metal surfaces does not cure until air contact is blocked.
Such anaerobic adhesives can be purchased and used commercially available products, preferably tetraethylene glycol dimethacrylate.

Hereinafter, the present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited to the following examples.
Example 1
Beads were prepared by washing wire rope and shank of steel alloy (piano wire) material having a diameter of 1.0 mm and having a cross section of 7 × 7, and then brazing diamond with nickel (Ni) on the outer surface of the shank. A plurality of the beads were inserted into the wire rope, and both ends of the wire rope were bound to endlessly. The beads were secured by placing them on the paste-coated area, while sufficiently applying anaerobic adhesive (Loctite, USA) at equal intervals to the wire rope area to which the beads were to be fixed. Then, the bead-fixed wire rope was left to stand for about 24 hours to bond the beads to the wire rope. Then, the bead and the beads were coated with polyurethane using a coating equipment to prepare a diamond endless wire rope saw of the present invention.
Example 2
Beads were prepared by washing wire rope and shank of steel alloy (piano wire) material having a diameter of 1.0 mm and having a cross section of 7 × 7, and then brazing diamond with nickel (Ni) on the outer surface of the shank. A plurality of the beads were inserted into the wire rope, and both ends of the wire rope were bound to endlessly. The beads were secured by placing them on the paste-coated area, while sufficiently applying anaerobic adhesive (Loctite, USA) at equal intervals to the wire rope area to which the beads were to be fixed. Then, the bead-fixed wire rope was left to stand for about 24 hours to bond the beads to the wire rope. Then, the diamond endless wire rope saw of the present invention was manufactured by coating the beads between the beads with a polyurethane containing 5% by weight of diamond powder having a particle size of about 325 mesh using a coating equipment.
The bond strength and tensile strength of the wire rope saws according to Examples 1 to 2 thus prepared and after cutting (after use) of the Poly-Si ingot under the following conditions were measured and described in Table 2 below. In addition, the cutting speed and life of the endless wire rope saw according to the present invention was measured and described in Table 3.

2. Cutting equipment: Multi type dedicated M / C
3. Cutting size: 25 bars / 1 ingot of 156 × 156 × 250㎜
4. Cutting method: X-axis 6 lines, Y-axis 6 lines simultaneous multi-cutting
Cutting quantity
On the other hand, using a wire rope saw according to Examples 1 and 2 was measured in the cut state of the silicon bar (Bar) is shown in Table 4 below.
1) is the process of blocking ingots into squares, and 2) is the process of cutting the top and ends of the square blocks.
As can be seen from Tables 2 to 4, the endless wire rope saw according to the present invention has excellent durability, such as bonding strength and tensile strength, both before and after use, and can be cut very thinly, resulting in loss of raw materials during cutting. In addition, the cutting conditions such as roughness, squareness, and flatness of the cut bar are excellent, so that precise cutting is possible. In addition, the endless wire rope saw according to the present invention is not only multi-cutting is possible, the cutting speed is very efficient, the life of the wire rope saw is long, there is an effect that the removal and installation is very easy.
