Cutting hard aggregates can shorten the life span of your blade, slow down the cutting rate, and thus uses more power. If the aggregate of the concrete you are cutting is hard, the process will cost more than when the aggregate is soft. Thus, it is important to know the material you are cutting and what it is composed of. Hard aggregates include quartz, while soft aggregates include limestone.
If you need to cut concrete with hard aggregates, your diamond blade should have segments equipped with tough diamonds and soft metal bonds. If not, the diamond particles will easily get worn down and will, as a result, glaze the blade, rendering it unable to cut.
If you are cutting soft aggregates, on the other hand, your blade segments should be equipped with hard metal bonds, which will ensure that the diamond particles are maintained while your blade is still usable.
2.size of cutting object
It’s not just the texture of your aggregate that matters. The size is also important as this determines the speed at which your diamond blade cuts, which will also affect its longevity. the thinner aggregate will, as expected, cut more easily and thus take less time. Cutting hard aggregates will take more cutting time and will take a toll on your blade.
3.cutting speed
When cutting at high speeds, blades are susceptible to distortion. This is why they have to come in a dish shape that allows the blade to rotate at optimum speeds. However, this means that each blade has its specific cutting speed limits. If this speed is not met, the blade will wander, which cause it to wobble from side to side and thus will not be able to cut a straight line.
On the other hand, there is also a maximum speed limit. It is crucial that you do not use a blade above the maximum RPM limit as doing so may result in injury or even death. This limit is stamped on the blade to ensure that all users are informed of it before they begin cutting.
4.The use of coolants
Coolants are used to cool most diamond blades. If there is not enough coolant, the fine particles will not be removed, and over time, this will cause the abrasive particles to wear away a part of the steel core that attaches to the diamond segments. Aside from that, there is the tendency to make the core overheat, which can lead to cracks and loss of segments, two factors that will significantly affect future performance and blade life.
