The Effect Of The Number Of Teeth On A Diamond Saw Blade

The number of teeth of the diamond saw blade has a relatively fixed ratio. Normally, for a saw blade with a diameter of 900mm, the number of cutter heads is generally 64. For a saw blade with a diameter of 1000mm, the number of saw blades is mostly 70, while for a saw blade size of 1600mm, the number of blades is generally 108. This is the case with large saw blades, so is it possible for saw blades of the same size, with reduced or increased teeth, and is there any special purpose?

The answer to this question is yes, Saw blades with different serrations can be determined by customization, such as cutting relatively hard granite, In order to increase the impact and sharpness of the cutter head, if the number of saw teeth is reduced and the cutting area is reduced, the cutting performance of the segment can be maximized. In order to meet such requirements, the sawtooth can be appropriately reduced, and even some stone manufacturers will deliberately weld a few less segments or weld a few poor quality segments for mixed welding when welding segments. In fact, this is all to increase the sharpness of the cutter head. Of course, the disadvantages of this are also very obvious, because doing so will undoubtedly reduce the service life of the segment.

There are also ways to change the sharpness of the segment by increasing the number of segments. For example, on the same saw blade teeth, the segment is divided into two pieces, For example, a 40mm long segment is divided into 20mm lengths for welding separately, and two cutter heads are welded on a saw blade serration. During the cutting process, there will be a small sub-tooth between the segments. This sub-tooth can improve the cutting efficiency to a certain extent. Compared with the same number of serrations, this welding method with twice as many serrations can not only maintain continuity, but also reduce the risk of falling off the segment.

Of course, during the cutting process of large saw blades, due to the many cutting risks and the high cost of customizing the substrate, many times, it cannot meet all cutting needs. There are even many problems sometimes, and the segments that need to be assembled require special customization. Therefore, most saw blades that change the number of teeth are on small and medium-sized saw blades, such as saw blades with a diameter of less than or equal to 300mm. The change of saw teeth is particularly obvious on these saw blades. But all in all, the change of the saw blade brings about three changes in the role or performance of the saw blade.

Adding and subtracting serrations changes the cutting performance of the saw blade, mainly in sharpness. A saw blade with more serrations results in a larger cutting area. Therefore, under the same current, the cutting ability is decreased, but it is not a separate attribute, and it is also related to the size of the saw kerf. The smaller the number of teeth, the larger the kerf and the sharper the cut, but the shorter the life. If the number of teeth is more, the kerf will be finer and the cutting sharpness will be worse, but the life will be longer.

The increase and decrease of saw teeth change the cutting quality of the saw blade, which is mainly reflected in the continuity of the saw blade teeth. The finer the saw blade kerf, the more serrations (specially point out the continuous piece, which is different from other saw blades), the better the cutting quality, on the contrary, the less serrations of the saw blade, the larger the kerf, the better the cutting ability and the poorer the cutting quality.

Adding and subtracting serrations makes a difference in blade life, mainly in terms of the number of parts actually cut. Increasing the teeth increases the life of the saw blade, while reducing the teeth is a practice that reduces the cutting life of the saw blade.
