hint:
1. Before tapping, confirm whether the diameter of the round hole is appropriate, and take protective measures during work.
2. When tapping, it is necessary to add water or coolant for cooling to prevent the temperature from being too high and reduce the loss of tapping. If the rotation is difficult, the tapping should be suspended.
3. For the complex tapping process, be sure to choose the appropriate cutting oil, and apply anti-rust oil for maintenance after use.
