Do you know high quality diamond blades may not work well for your job? This is true. Your diamond blades should fit your application. Here we give 8 easy tips you can use when you are buying diamond saw blades.
Normally, using diamond saw blades with adequate water (wet cutting) can extend the blades’ life and control dust. However, in some situations, dry cutting should or has to be performed. These situations include:
There are 3 main criteria when evaluating the performance of a diamond saw blade: cutting efficiency, service life and processing quality.
Diamond grit indicates the size of the diamond. The diamond’s protrusion height on the cutting surface of the diamond saw blade influences how deep the diamond can cut, while deeper cutting means higher cutting efficiency. If the diamond is big, its exposed portion can be higher, so its cutting efficiency can also be higher. Therefore coarser diamond grit leads to higher cutting efficiency of the diamond saw blade.
The meaning of a diamond tool’s diamond concentration is the weight of the diamonds in a unit volume of the diamond tool’s working layer, and it is defined that when each cubic centimeter contains 0.88g diamonds, the concentration is 100%. This definition also applies to CBN abrasives.
Diamond grinding has many benefits. It is fast, low-noise and low-cost. It is very popular in the construction and home improvement industry. Diamond cup wheels are the diamond grinding tool which is often used to grind concrete, stone and masonry materials.
When you are going to buy diamond saw blades, you should first identify what kind of blades you need. If the diamond blades’ quality is much higher than your needs, you will waste your money; if their quality is lower than your needs, you (or your customers) will not be able to complete your (or their) jobs; if there are no problems with the diamond blades’ quality, but the blades just do not match the objects to be cut, you also can’t do your jobs well.
In my previous article about how to choose diamonds’ grit, I said some main points you should consider. There are still many other points which are also important.
When choosing the diamonds’ grit of a diamond tool, we should consider the workpieces’ roughness requirement, the tool’s cutting/grinding efficiency and the best grit range of the tool’s bond.
