What problems will be encountered during the tapping process of the automatic tapping machine?

1. When the tapping machine cannot tap the screw hole, it is necessary to withdraw the tap frequently to remove the chips in the hole.

2. The cutting speed during machine attack is 6-15 m/min for general steel; 5-10 m/min for quenched and tempered steel or harder steel; 2-7 m/min for stainless steel; 8-m/min for cast iron 10 meters per minute. In the same material, the smaller tap diameter takes the higher value, and the larger tap diameter takes the lower value.

3. When tapping, every 1/2-1 turn of the twister should be turned back, so that the chips can be easily discharged after breaking, and it can reduce the phenomenon that the cutting edge is stuck due to sticky chips.

4. When changing to the next tap during the tapping process, first screw it into the tapped and threaded thread by hand. When it can no longer screw in, then use the twister to turn it. When the end taper is finished tapping and withdrawing, it is also necessary to avoid turning the wringer quickly. It is best to unscrew it by hand to ensure that the quality of the tapped thread is not affected.

5. When tapping, the calibrated part of the tap can not be completely out, otherwise it will produce disordered teeth when the tap is withdrawn from the reverse rotation.

6. The cutting speed during machine attack is 6-15 m/min for general steel; 5-10 m/min for quenched and tempered steel or harder steel; 2-7 m/min for stainless steel; 8-m/min for cast iron 10 meters per minute. In the same material, the smaller tap diameter takes the higher value, and the larger tap diameter takes the lower value.
