What are the causes of thread rot during tapping?

There are many reasons why rotten teeth often occur in the threading process, both for tools and for materials.

If there is a defect in the material, there is a high probability of rotten teeth, in which case the quality of the material needs to be controlled, such as the casting process, to ensure the density of the material. The possibility of material problems in forgings and rolled parts is smaller, and the quality of raw materials can be ensured by selecting the best manufacturers for supply quality.

There are many reasons in the processing process, because tapping threads are more common, the following figure briefly introduces the rotten teeth in the tapping process, and the situation of threading is similar.

It may be that the bottom hole is not well laid, small or crooked, resulting in abnormal tapping, or your machine can not automatically work back, when the tap is withdrawn, it is recommended to use the automatic worker to enter and retreat the tooth distance tapping machine, the tapping wire is very good, and the efficiency is also high, the accuracy is also high, our company is using this kind of machine, my friend is a sales general tapping machine drilling machine.

There is also a reason that there are problems with the tapping tools used, I used to have such a problem, and then changed to pneumatic tapping, you can completely solve the problem of tapping wear and can not remove iron filings, my factory is now using Dejian pneumatic tapping machine, used for a year, the wire mouth has not been broken and there is no wear and tear, and at the same time can tap a tooth in a second, the accuracy rate is 98%, and it can also rotate 360 degrees, which is very easy to use.

1: The bottom diameter of the hole is smaller.

2: The tapping is worn.

3: The rotation speed is too fast.

4: The iron filings inside are squeezed.

Where speed is key.

1: The hole is too small.

2: The silk attack is not fast.

3: Poor tapping skills.

4: There is a problem with the material.

What are the causes of thread rot during tapping? Kiss! Hello, I am glad to answer for you<> what are the reasons for thread rot when tapping threads?

1. If the bottom diameter of the thread is small during processing, the tapping will hurt the nearby screw teeth during processing, resulting in the rotting of the screw teeth from the processing comma. 2 Similarly, if the tap is worn, it will also lead to abnormal threads. 3. If the speed is unreasonable when tapping, it will also make the processed thread have problems, and it is easy to damage the thread if it is too fast.

4. The iron filings in the hole in the first process of processing the disadvantages cannot be removed in time, and the screw teeth will be squeezed out. 5 Among these influencing factors, speed is the key, and unreasonable speed is the main reason for the damage of the screw, after all, only fast is not broken, and speed represents everything. Hope mine can help you <>

Do you have any other questions?

Summary. Kiss, the reasons for thread rot when tapping threads are as follows! 1.

If the bottom diameter of the thread is small during processing, the tapping will hurt the nearby threads during processing, resulting in rotting of the processed threads! 2.If the tapping is worn, it will also lead to abnormal machining of the threads, and if the speed is unreasonable, it will also cause problems with the processed threads!

3.If it is too fast, it is easy to damage the iron filings in the hole during the processing of the screw teeth, and it will also squeeze out the screw teeth.

Kiss, the reasons for thread rot when tapping threads are as follows! 1.If the bottom diameter of the thread is small during processing, the tapping will hurt the nearby threads during processing, resulting in rotting of the processed threads!

2.Kiss, if the tapping is worn, it will also lead to abnormal processing of the thread, if the speed is unreasonable, it will also make the processing of the quiet thread problem! 3.

If it is too fast, it is easy to damage the iron filings in the hole during the processing of the screw tooth, and it can not be removed in time, and the screw tooth will be squeezed out of the bird.

In general, there are many reasons why rotten teeth often occur in the threading process, including tools and materials! The details are as follows:1

In this case, it is necessary to control the quality of the material, such as controlling the casting process to ensure the density of the material! 2.Kissing, forgings and rolling parts are less likely to have problems with rolling materials, and the quality of raw materials can be guaranteed by choosing the best manufacturers for supply quality!

Hello, there are several reasons for the occurrence of Changyu thread rot when the slag taps the Xun quiet thread: 1: the bottom diameter of the hole is small 2: the tap is worn 3: the speed is too fast 4: the iron filings inside are squeezed, in which the speed is the key.

LZ, do you ask a fitter or a turner?

Generally, tap manufacturers make general-purpose taps when producing taps, but when the material changes, the shortcomings exposed by general-purpose taps are obvious, such as thread rottenness, poor finish, and the situation that the Z end of the plug gauge cannot be stopped. Find a professional tap manufacturer or professional tap sales staff to adjust according to your processing situation. Usually this kind of problem is a simple problem when a customer has such a problem.

Could it be caused by the difference in the tooth distance between the screw hole and the screw Of course, it may be caused by excessive force, after all, the hardness of steel is limited.

1. The length of the screw is not enough to withstand the corresponding torque.

2. The strength and hardness of the screw are not enough (possibly due to the quality of the material, process, etc.) to withstand the corresponding torque.

3. The force of tightening the screw exceeds the standard load of the screw, resulting in slippage.

4. The threaded holes or threaded threads are not standard, and they are not tightly combined with each other.

5. The screw itself stops the gauge, which will also cause the consequences of tooth slippage.

6. The outer diameter of the tooth is small, if the normal machine uses a normal thread, the outer diameter of the tooth is small, and the tooth will definitely slip.
