A, broken teeth, appeared in the process of cold saw blade used in cracked tooth phenomenon:

1, speed and feed speed too fast,

2, the material bend too much lead to unstable fixture tightening

3, circular saw machine in the power output is usually unstable belt too loose or broken

Second, the cold saw blade is not durable, the same (material and saw blade specific) :

1, the feed speed too fast,

2, magnetic powder resistance condenser failure

3, to protect the knife block didn't adjust well

Three, cut down the relationship between the workpiece is not vertical and cold saw blade:

1, the feed speed too fast or fog cooling is not normal, cause the cold saw blade knife plate blade deformation due to overheating

2, knife block deformation cause cold saw blade knife plate blade deformation due to overheating
