NAME : UMMIE KHALEEDA MOHD RAZALI MATRIX ID : GROUP : ASB TOPIC : <strong>DIAMOND</strong> TOOL MATERIAL <strong>FOR</strong> <strong>WOOD</strong> <strong>CUTTING</strong> <strong>DIAMOND</strong> TOOL A diamond tool is a cutting tool with diamond grains fixed on the functional parts of the tool via a bonding material or another method. As diamond is a super hard material, diamond tools have many advantages as compared with tools made with common abrasives such as corundum and silicon carbide. <strong>ADVANTAGES</strong>/DIS<strong>ADVANTAGES</strong> <strong>OF</strong> <strong>DIAMOND</strong> TOOL <strong>OF</strong> <strong>WOOD</strong> <strong>CUTTING</strong> <strong>ADVANTAGES</strong> DIS<strong>ADVANTAGES</strong> 1. High hardness and wear resistance of diamond cutting edge is very sharp blade roughness value 2. low friction coefficient, good anti-adhesion 3. high thermal conductivity 4. easy to stick the knife and BUE cutting 5. the machined surface good quality. 6. In the processing of nonferrous metals, the surface roughness up to R0.10? 0.05μ m 7. the machining accuracy of up to IT5 (hole IT6) above 8. effective in processing nonferrous metal materials and non-metallic materials such as copper, aluminum, etc. 9. non-ferrous metals and their alloys 1. Diamond's drawback is the poor toughness 2. low thermal stability 3. chemical reaction when in contact with the iron group elements (4C +3 of Fe &#; Fe3C4) 4. carbonization (graphitization) at 700 ~ 800 &#;, generally does not apply to the processing of steel 5. When cutting nickel-based alloys, the same will wear quickly. 6. Usually do not recommend the high melting point metals and alloys of diamond cutting tools. In addition, the diamond tool grinding is difficult and expensive.
Sawing and drilling tools embedded with diamond grains are the most effective cutting agents in the construction industry. Diamond is known as the hardest substance in the world, and it also possesses other qualities that make it a prime candidate for use in concrete cutting.
The benefits of diamond sawing and drilling are clear cut when compared to other materials commonly used as abrasives. Tools that use diamonds have higher wear resistance, higher grinding efficiency, and a longer lifespan. Diamond saws and drills will help ensure a high-quality cut for concrete projects, and will reduce time and effort.
Synthetic diamonds are a regular fixture in the construction industry. The molecular structure of a diamond is very compact &#; the smaller the diamond, the greater the density. Smaller crystals cut through harder materials better because they produce a larger cutting surfaces, and larger crystals are used for cutting softer materials. Diamond density is comparable to impact strength, and the ability to withstand heat. This range in size and density allows for a more customizable approach to each unique job.

Diamonds will embed into saw edges and drill ridges through a metal bonding process that utilizes heat to seal the crystals into the edge of the tool. There are also resin, ceramic, and electroplating methods used for bonding. The crystals will fracture over the lifespan of the cutting tool, which creates more cutting surfaces. For this reason, diamond drills and saws are more effective after several uses, which provides an advantage over common abrasive materials, like silicon carbide or corundum.
The cutting surface provides a high resistance to wear, and generates less heat while operating. Diamond saws are less likely to burn or fracture the surface it is cutting, and makes a cleaner cut. Drills with diamond bits also have greater accuracy, and produce less debris than carbine drills, which preserves the concrete&#;s integrity, and reduces the chances of structural damage. The reduction in equipment wear and operating time translates into cost reduction for your project.
The higher velocity saw blades and drill bits reduce noise. Higher speed produces less resonance, which produces less noise. This feature supports safety in the workplace, as noise damage is a concern on many job sites.
