          Broach teeth in the broaching process crack, we want to understand why will crackfirst, what part of the cutter tooth crack! Broach hardness in general to maintain in 55- 64, according to the requirements of customers. Is mainly to see the customer tobroach broaching workpieces material if required, the workpiece of different materialsto pull broach hardness requirements are not the same. Factors and broach hardnessalso involves durable etc..

          Kai printing not only we broach broach that will detect the hardness in the factory before delivery to the customer, detection there will also carry on the hardness, somedetection strict customer hardness less time will directly return. Kai printing broachbroach remind so when heat treatment do not be careless, for broach hardness must be strictly controlled. Hardness is not up to standard, the broaching process will produce the cutter tooth crack occurrence, especially in heat treatment is not uniformbroach the same way. In some places, some places of high hardness, low hardness,so the hardness of the inhomogeneous case, the possibility of the cutter tooth crack is greater.

          The reason we determine the broach hardness, sometimes the customer directly tobroach the hardness will have a standard. This standard is to prevent some toolmanufacturers of hardness is not strictly controlled, it will cause some problems.
