Slotting in heat treated parts is similar to the process shaping.
Slotting in heat treated parts is used for shaping profiles heat treated workpieces. As a result, hardening distortions are prevented.
Due to the hardening/ heat treatment of workpieces, their profiles often have a distortion. Often the profile is slightly different. As a result, tolerances are not achieved. The change in dimensions is not predictable. Therefore, the problem can not be solved by working with allowance on.
The slotting in heat treated parts results in a clearing of the hardened/ heat treated workpieces. As a result, a calibration of the specified profile dimensions is achieved.
