  Superabrasives Information
Superabrasives and diamond wheels includes a wide variety of cutters and grinding tools that use diamond or cubic boron nitride (CBN) abrasive grit as the cutting medium. 
These devices, including diamond wheels, abrasive saw blades, wheel dressers, grinding wheels and single point tools are used in applications where extreme strength and abrasiveness is required as diamond and CBN abrasive grains are among the hardest known materials.
CBN superabrasives are used in steel grinding applications where even diamond abrasives fail to perform. For the most part, products in the superabrasives and diamond wheels category are rotary devices which perform their grinding or cutting actions as they spin against a given material.

SELECT A DIAMOND TOOL

  1. The buyer is solely responsible for the correct selection of correct use of the diamond tools. The claims are invalid in case of incorrect selection or misuse or not observing to safety instructions.
    It is the fact that 99.9% of problems are caused by operate error and not product failure. Our blades should not fall if used correctly.
  2. What is a diamond saw blade
    A diamond saw blade is composed of the circular steel core and the diamond-impregnated segment. The segments separated by slots in the core. These slots assist in cooling the blade during sawing by allowing water (wet cutting) or air (dry cutting) to flow between the segments.
    The segments or rims are a mixture of diamond powders and metal powder. The diamonds are Industrial diamonds of different sizes and qualities depending on the material to be cut and blade type. During the process the metal powder and diamond powders are compressed at very high temperature and pressure to obtain the bond, which retains the diamond grain.
  3. How to make a diamond saw blade
    Laser welding: laser micro-fusion enables the segment to be welded to the core. The bond is the most powerful; it enables the tool to be used for dry cutting and drilling without segment loss.
    Brazing: silver brazing solder melts at high temperature between the segment and the core and binds the two elements together. This used for wet cutting, drilling and grinding.
    Sintering: it divides into two Cold pressed-Sintered: First pressed with press machine under normal circumstances, and then laid in sinter machine under high pressure and temperature making the compressed metal powder to a solid bond.
    Hot pressed: Pressed with hot machine under high temperature and pressure, making the compressed metal powder to melt to a solid bond.

  1. How does a diamond blade work
    The individual diamond crystals exposed on the leading edge and the sides of the segment or rim carry out the cutting (in fact it is milling).
    The operator pushes the rotating blade into the material. The surface diamonds thus exposed mill a groove in the material, reducing it to fine powder when the blade mills the material, the latter exerts wear on the blade.
    During cutting the exposed diamonds may crack or break. The material simultaneously starts to abrade the metal matrix, which gradually releases more diamonds. The more abrasive the material, the more rapid the tendency to wear down the matrix.
    Blades for cutting hard, dense less abrasive materials (such as tile, hard bricks, stone or cured concrete), require a softer metal matrix. This will wear faster, replacing the worn diamonds fairly quickly so that the blade continues to cut. Blades for cutting soft, abrasive materials (such as green concrete and asphalt) must have a hard, abrasion-resistant metal matrix in order to retain the diamonds for a long time.
  2. How to selecting a diamond tool
    When choosing a diamond tool you should follow under step by step.
    Step 1: How to use-Cutting or Drilling or Grinding
    Be sure that cutting blade is deadly dangerous to use for grinding and making a hole. You should not take the risk just to save meaningless small money using one blade doing all the work. Please refer to the detail content in the brochure.
    Step 2: What kind a machine to use on

    Step 3: Blade usage – How often you will use it and how long a life and how fast a cutting speed you required
  3. Professional Purpose: for large civil engineering construction on a regular daily basis, require long life (less expensive per cut/meter) and fast cutting speed.
  4. Builder’s (contractor) Purpose: for regular use with medium life, fast cutting speed no need the same life of a professional blade.
  5. DIY Purpose (trade): for small scale occasional use, require fast cutting speed and reasonable life.
  6. Promotional Purpose: cut well with water but with short life.

  7. Step 4: Blade Purpose – Consider what materials you to be cut
    Asphalt; Concrete; Brick; Block; Stone; Tile or General Purpose (this type can cut many of the materials, but can not get the best performance as special professional ones).
  8. If you want a blade that will cut both granite and asphalt well then you will need to buy two different blades. You cannot expect the blade to work correctly and safely on both materials. The blade will either become blunt and overheat or it will wear very quickly.

  10. Step5: Blade Type: A continuous smooth rim provides the smoothest cut in ceramic tiles and ornamental stone. Turbo type blades or segments turbo type may produce slight chipping but generally have a longer life and lower cost per cut than continuous rim blades. Segmented blades provide the longest life and lowest cost precut but are only suitable for work where chipping is not a problem.

  12. Step 6: The Price: For small jobs, or occasional use, a low-priced tool may be preferable. For larger jobs or regular use, a higher-priced tool will actually be less expensive to use because it will deliver a lower cost per cut. For really big jobs, the lowest possible sawing cost (cost per meter) is usually much more important than the initial price.
