Diamond Blade Tips

• Open up the diamonds on a new blade with shallow cuts in soft, abrasive material (eg. limestone). This will stop the blade chattering or skipping on the first job.
• For normal cutting, multiple shallow cuts (step cuts) are better than one single deep cuts.
• Do not force the blade. Forcing or twisting the blade can cause bluntness, excessive wear, overheating, distortion and segment damage.
• Do not side grind.
• If your slurry colour changes to brown or red, you are most probably cutting the dirt or sub base. This will wear your diamond blade quicker, so raise your blade.
• If you're going to change directions on a floor saw, make sure your machine is off and the blade is up out of the cut before changing direction.
• If your blade does not have a direction indication on it, you should be able to see a "comet tail" behind exposed diamonds if the blade was "broken in" at the factory. This indicated the direction - the tail should be behind the comet. If you put a blade on in the direction opposite to the directional arrow you may experience a little slower cutting or a little vibration at first until the diamond is exposed on the opposite side.  This should not harm the blade as long as you maintain the same direction but may reduce the life fractionally if it is continually reversed.
• A smaller blade on your machine will decrease the cutting depth, but increase the power and speed of cutting. For example, many customers use 12"/300mm blades on a cut off saw that could use a 14"/350mm blade.
• If you are using the blade dry (not recommended due to dust and safety issues), be aware that it will shorten the blade's life, and you will need to air cool the blade regularly -  take the blade out of the cut to allow the air to prevent the blade from overheating.

Diamond Blade Troubleshooting

Glazing - This is one of the most common diamond blade problems. As a diamond blade is used, the bond wears, exposing more diamond that continue cutting. If the bond does not wear back, then eventually there is no diamond exposed, so the blade will slow down and stop cutting. The cutting surface of the blade will feel smooth. This is known as glazing or polishing.
Rectify by re dressing the blade by cutting an #80 grit dressing stone ( we sell them here ).
As an alternative, use an abrasive material like limestone to remove some bond and expose diamonds so cutting can continue.
Possible causes are:

• The bond is too hard for the material it is cutting - select the correct blade.
• Too much water is being used (sometimes unavoidable if the tile cracks easily with heat)
• The machine is not powerful enough for the specification (usually experienced more with professional blades and saws)
• The blade has been mounted with the rotation arrow the wrong way.

Traditional woodworking saw blades are made of cemented carbide, and now PCD saw blades are entering the market with a brand new attitude. We all know that cemented carbide saw blades should be sharpened with resin diamond grinding wheels, so do you know what kind of grinding wheels should be used for grinding PCD saw blades? What are the advantages of this kind of grinding wheel?

 

Because the PCD is made from the synthetic diamond, it&#;s very hard, usually, we must use very high concentration diamond wheels like vitrified bond diamond wheels, which content 2times synthetic diamond than resin diamond wheels in each cubic mm³. As we know, resin bond are always good at the carbide tools, but not PCD tools. Even that, when we use vitrified bond diamond wheel to grind PCD with -# grit size even much more finer one, often we will remove almost as much stock from the wheel as comes off the PCD tools. MORESUPERHAD can supply quality PCD grinding wheel at very long life as well as fast cutting. We only choose the very strong synthetic diamond as the raw materials, we make sure not only the particle shape is round enough but also be with some sharp points, which can make sure we won&#;t lose the efficiency while we still want enough life from the wheels. So it will help you get fast, stable, much more PCD tools in unit time.

What are the advantages of this kind of grinding wheel?

1.      The porous structure of the abrasive improved diamond exposure and can prevent vertical streaks on workpiece and improve surface quality

2.      Accurately control geometric tolerances to make a good abrasive layer

3.      Good self-sharpening, high grinding efficiency, high wear resistance and less abrasive grain consumption

4.      High precision workpiece. PCD tools can reach high efficiency, good surface finish and edge no chipping

5.      Vitrified bond wheels offer tool life greater than 150 times that of a resin bond wheel and can be easily trued and dressed on the machine
