The tapping machine often encounters such and other problems in the tapping process. This is a special summary of some of the problems and solutions that the tapping machine often encounters in the tapping process. I hope it can help you:
1) The hole of the threaded bottom hole on the workpiece should be chamfered, and both ends of the through-hole thread should be chamfered.
2) The position of the workpiece clamp should be correct, and the center line of the threaded hole should be placed in a horizontal or vertical position as much as possible, so that it is easy for tapping to judge whether the axis of the tap is perpendicular to the plane of the workpiece.
3) At the beginning of tapping, try to put the tap as straight as possible, then apply pressure to the tap and turn the twister. When cutting in for 1-2 turns, carefully check and correct the position of the tap. Generally, when cutting into 3-4 turns of thread, the tap position should be correct. Afterwards, you only need to turn the wringer, and you should not put pressure on the tap, otherwise the thread profile will be damaged.
4) When tapping, every 1/2-1 turn of the twister should be reversed about 1/2 turn, so that the chips can be easily discharged after being broken, and the phenomenon that the tap is rolled by the cutting edge due to sticky chips can be reduced.
5) When encountering a screw hole that cannot be tapped, withdraw the tap frequently to remove the chips in the hole.
6) When tapping the screw holes of plastic materials, lubricating coolant should be added. For steel materials, oil or emulsion with a high concentration is generally used, and professional tapping oil tapping oil is available for those requiring higher tapping technology. For high-precision stainless steel tapping, professional stainless steel tapping oil can be used. Steel, carbon steel, A3 iron, high precision, complicated tapping, etc. In order to save some oil money, paraffin oil is used, which has strong adhesive force, is difficult to clean, and is easy to rust, and some use soybean oil. Rapeseed oil and the like are particularly difficult to clean, and many electroplating encounters peeling problems, and the rejection rate is high. The problem can be solved by professional tapping oil.
7) When changing to the next tap during the tapping process, screw it into the tapped thread by hand until it can no longer be screwed in, and then turn it with a twister. When the end cone is finished tapping and exiting, it is also necessary to avoid rapidly turning the wringer, and it is better to unscrew it by hand to ensure that the quality of the tapped thread is not affected.
8) When machine tapping, the tap and the screw hole should be kept coaxial.
9) When the machine is attacking, the calibration part of the tap cannot be fully advanced, otherwise it will produce random teeth when the tap is withdrawn from the back.
