The main causes of improper threading in thin sheet tapping include improper operation and material characteristics. Specific factors and solutions are as follows:
II. Operational Factors
Tap not perpendicular to the workpiece end face
If the tap axis is not perpendicular to the workpiece end face during tapping, uneven force distribution can cause thread deviation. Adjust the tapping angle to ensure the tap is perpendicular to the workpiece end face.

Uneven hand force application
During manual tapping, uneven force or unstable posture can easily cause the tap to tilt. It is recommended to hold the tap steadily with both hands, apply force evenly, and keep the tap axis aligned with the workpiece center.

Inaccurate equipment alignment
If the hole center is not aligned during mechanical tapping, the tap may deviate from the axis. Check the equipment's positioning accuracy to ensure the tap aligns with the hole center axis.

III. Material Characteristics
Internal material defects
Defects such as sand holes or inclusions in thin sheet materials may hinder normal tap cutting, leading to deviation. Inspect the material surface quality before tapping and remove surface impurities.

Uneven material hardness
Local variations in hardness in thin sheets may cause unbalanced force on the tap. It is advisable to select tap types suitable for the material (e.g., cobalt high-speed steel taps) and control cutting speed to reduce wear.

IV. Other Considerations
Cutting fluid usage: Ensure sufficient cutting fluid to prevent tap jamming or deviation due to inadequate heat dissipation.

Pilot hole accuracy: The pilot hole diameter must be strictly controlled within tolerance to avoid thread deviation caused by hole size inaccuracies.
