Broaching tools works with the principles of removal of chips by the teeth which gradually rise.
These teeth, which work in a serial manner, will come to fruition over time due to reasons such as friction, warming, etc., and this is normal. Each broach must be sharpened in certain periods. These periods depends on such factors as the type of material being broached, the hardness of the material, the cutting oil used, the rigging of the apparatus and fixtures of the broaching machine. And these periods are determined by the number of pieces that can be broached. If these periods are not respected, your broach may be strained and broken.
Sharpening operation is done by interfering with the aim of obtaining maximum yield on the cutting surfaces of the teeth on the broach sharpening machines.
The tooth mouths that underwent deformation over time are reshaped so that the broach reaches its first day form. If there are any problems that occur over time on the broached parts, this is taken into account and a grinding program is applied accordingly.
Care must be paid to the grinding periods for not creating these genre problems.
