The cutting principle of a diamond wire saw relies on the embedded diamond particles on the wire to grind and break the surface of the material being cut. Here are the key points:
1. Diamond Particles: Diamonds are one of the hardest natural substances on Earth, making them ideal for cutting and grinding. In the manufacturing process, diamond particles are embedded onto the wire to form a series of cutting "teeth."
2. Cutting Method: The diamond wire saw primarily utilizes grinding cutting. As the wire saw moves, the diamond particles come into contact with the material's surface, grinding away and rapidly breaking the atomic bonds of the material, thereby reducing it.
3. Breaking Mechanism: The pressure generated by the diamond particles during cutting causes a local increase in pressure, leading to the fracture of the material's surface. It's similar to using an extremely hard knife to cut through a fragile material, but with diamond particles, the hardness is much higher than any conventional cutting tool.
4. Cooling: The cutting process generates friction and heat between the diamond particles and the material. To prevent overheating and damage to both the wire saw and the material, cooling is essential. Water or other cooling fluids are usually provided to the cutting area to lower the temperature and flush away debris.
5. Flexibility of Wire Saw: The diamond wire saw, composed of diamond particles and a steel wire, offers high flexibility, enabling cutting on various curved and intricate materials. The wire's flexibility allows the saw to access tight spaces, which might be difficult for other cutting tools.
In summary, the diamond wire saw achieves cutting by utilizing the hardness and wear resistance of diamond particles, which grind and break the material's surface upon contact. Its advantages include suitability for various material hardness, ability to cut complex shapes, and longer lifespan due to the diamond particles' low wear rate. However, it requires proper cooling to avoid overheating and ensure efficient cutting.
