Is the number of saw teeth an advantage

How many sawtooth number is not good or not good? The answer is to select the number of saw blade serrations should not be too many. It is necessary to judge the reasonable and accurate data of sawing according to the actual needs.

Is the number of teeth too many of high speed steel circular saw blade advantageous or inferior?

Too much will lead to the reduction of saw distance (tooth distance selection and extremely long chip distance, and the specific relevance of workpiece raw materials), resulting in low elasticity or simple damage to the serration of metal circular saw blade. If it is necessary to use more fine teeth, it is also necessary to use carefully, especially pay attention to the direction of iron chips during sawing to prevent entering the internal of the saw tooth joint.

1、 Analysis of the advantages of the excessive number of teeth in metal circular saw blade

(1) The blade with multiple teeth will improve the cutting speed (cutting amount per tooth)

(2) For the surface of the block workpiece, the larger the tooth quantity is more smooth, but does not represent the parallelism of the block.

(3) The probability of burr after cutting the saw blade to block the workpiece

(4) The stability of blocking is good, and it will not return to the knife

2、 Analysis of the disadvantage of the excessive number of teeth in metal circular saw blade

(1) If iron chips enter the saw tooth gap of metal circular saw blade, it is not easy to discharge, which leads to the failure of outstanding touch between saw tooth and cut data, which will affect the quality of blocking.

(2) The elasticity is too low, the number of sawtooth cannot be added, only cut;

(3) The chip tank is too full, and the instability factors are formed simply;

(4) If the number of teeth of metal circular saw blade is so many, it will lead to the seizure of data;

(5) The heat dissipation is difficult, which causes the temperature too high and the operation stability is greatly affected;

(6) Compared with the large saw saw, the wear is faster, forming the cost of adding;

(7) The length of time used, that is, the number of life, is relatively low.

So what are the advantages of using the correct pitch?

Correct pitch for adding or cutting feed

Low calorific value

Less tooth jumping (the edge of teeth will not be hot melted)

Progressive blade grinding life per time (maximum square number of saws per saw)

Improve the number of saw blade grinding

When using metal circular saw blade with more teeth, the power of chip removal should be increased as much as possible, and cooling system should be used to prevent the expansion of downwind.
