Common problems of thread processing

The tap is broken:

1. The diameter of the bottom hole is too small, and the chip removal is not good, causing cutting blockage;

2. The cutting speed is too high and too fast when tapping;

3. The tap used for tapping has a different axis from the diameter of the threaded bottom hole;

4. Improper selection of tap sharpening parameters and unstable hardness of the workpiece;

5. The tap has been used for a long time and is excessively worn.

Taps collapsed: 1. The rake angle of the tap is selected too large;

2. The cutting thickness of each tooth of the tap is too large;

3. The quenching hardness of the tap is too high;

4. The tap has been used for a long time and is severely worn.

Excessive tap pitch diameter: improper selection of the pitch diameter accuracy grade of the tap; unreasonable cutting selection; excessively high tap cutting speed; poor coaxiality of the thread bottom hole of the tap and the workpiece; inappropriate selection of tap sharpening parameters; tap cutting The cone length is too short. The pitch diameter of the tap is too small: the accuracy of the pitch diameter of the tap is incorrectly selected; the parameter selection of the tap edge is unreasonable, and the tap is worn; the selection of cutting fluid is inappropriate.
