Diamond abrasives represent a number of the simplest cutting and grinding tools available for the concrete, asphalt and stone industries. Selecting the proper tool for the work can often be a challenging task, so here are some basics to urge you started.

BLADE CONSTRUCTION

First, it's important to know what a diamond blade is. Diamond blades are comprised of diamond impregnated segments attached to steel core. they're wont 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 planning 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 warmth treated to make 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 show the diamond particles. The blade core is tensioned to make sure stability and straight cutting. the ultimate step is painting and adding the security labeling. 

Diamond blades add a grinding or chipping action. The synthetic diamond particles hit the fabric being cut, breaking it down and removing the fabric from the cut. Diamond segments are available different designs like standard segment, turbo, wedge or continuous rim. the various configurations optimize the specified cutting action, enhance cutting rate and prolong the lifetime of the diamond blade.

THE BOND

Selecting the right bond during a diamond blade is extremely important to make sure optimal cutting performance. The difference between a cured concrete diamond blade and an asphalt diamond blade is within the composition of the bond wont to hold the diamonds in suspension. Since the diamond is doing the cutting, the bond must affect to repeatedly expose new sharp cutting diamonds. 

Cured concrete may be a hard, dense material, therefore the bond during a cured concrete blade is taken into account to be a soft bond. it's designed to repeatedly expose new diamond cutting particles. All of our concrete blades are designed to encounter reinforcement of 1 form or another. Mesh or rebar will slow the cutting rate down alittle amount. Let the blade do the work, there's no got to add additional pressure. Asphalt may be a soft, abrasive . The hard bond on an asphalt cutting blade is meant to resist wear and hold the diamond particles in situ . This ensures efficient diamond cutting action and maximum blade life. 

DIAMOND BLADE APPLICATION

In order to work out the simplest diamond blade for the work , confirm to answer these important questions:

JecarJecarWhat quite saw is getting used – high speed or walk behind (high or low horsepower)?

Will the cutting be done wet or dry?

What quite material is being cut – cured concrete, green concrete, asphalt or asphalt over concrete?

What level of performance do i want - higher quality diamonds may cost more, but offer greater cutting performance, life and overall value?

USING the incorrect BLADE

If a concrete blade is employed to chop asphalt, the bond will wear quickly and therefore the blade life are going to be short. The reverse is true if using an asphalt blade to chop concrete. The exposed diamonds will wear but the bond won't . The cutting surface of the diamond segments will polish and glaze over. When the bond doesn't erode, no new diamonds become exposed, eventually causing the blade to prevent cutting, overheat, and eventually end in damage to the segment and/or the core.

DIAMOND BLADE USE AND SAFETY

Install the diamond blade correctly on the machine, ensuring 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 suits OSHA regulations by using approved dust control measures (supply water to the saw).

When wet cutting, make sure that there's adequate water system . Insufficient water system can cause blade overheating and failure of the segment or core.

If employing a high-speed saw, don't make long continuous cuts with a dry diamond blade. Periodically remove the blade from the cut for a couple of seconds and permit it to chill .

Never force a diamond blade into the workpiece. Allow the diamond to chop 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 chop through the concrete or asphalt into the “sub base" material, as this may end in excessive wear and failure of the blade.

Never use a damaged blade or a blade that exhibits excessive vibration.
