Diamond blades are comprised of diamond impregnated segments attached to steel core. They are used to cut cured concrete, green concrete, asphalt, brick, block, marble, granite, ceramic tile, or just about anything with an aggregate base
Diamond Blade Use And Safety
Install the diamond blade correctly on the machine, making sure that the directional arrow on the blade matches the arbor rotation on the saw.
Always use properly adjusted blade guards when operating saws.
Always wear proper Personal Protective Equipment – eye, hearing, respiratory, gloves, feet and body.
Always comply with OSHA regulations by using approved dust control measures (supply water to the saw).
When wet cutting, ensure that there is adequate water supply. Insufficient water supply can lead to blade overheating and failure of the segment or core.
If using a high-speed saw, do not make long continuous cuts with a dry diamond blade. Periodically remove the blade from the cut for a few seconds and allow it to cool.
Never force a diamond blade into the workpiece. Allow the diamond to cut at its own speed. If cutting particularly hard or deep material, “step cut” by cutting 1″ at a time.
Do not allow the diamond blade to cut through the concrete or asphalt into the “sub base” material, as this will result in excessive wear and failure of the blade.
Never use a damaged blade or a blade that exhibits excessive vibration.
Blade Construction
First, it is important to understand what a diamond blade is. Diamond blades are comprised of diamond impregnated segments attached to steel core. They are used to cut cured concrete, green concrete, asphalt, brick, block, marble, granite, ceramic tile,
or just about anything with an aggregate base. The segments are formulated with synthetic diamond particles mixed in precise amounts with powdered metals that compose the bond. Diamond particle size and grade are tightly controlled and optimized for the intended application. The formulation step is critical to the design and performance of a diamond blade. The mixture of powdered metals (the bond) significantly affects the cutting ability of the blade in various materials. This mixture is poured into a mold, compressed and heat treated to form the segment. Segments are attached to the steel core by laser welding, sintering or silver brazing. The working surface of the blade is dressed with an abrasive wheel to expose the diamond particles. The blade core is tensioned to ensure stability and straight cutting. The final step is painting and adding the safety labeling.
Diamond blades work in a grinding or chipping action. The synthetic diamond particles collide with the material being cut, breaking it down and removing the material from the cut. Diamond segments come in different designs such as standard segment, turbo, wedge or continuous rim. The different configurations optimize the desired cutting action, enhance cutting rate and prolong the life of the diamond blade.
