Automatic tapping machine is a kind of machine tool that uses taps to process internal threads. It is a kind of machine tool that is widely used to process internal threads. Since the automatic tapping machine is facing the market, it has been favored by the majority of users because of its lightness, flexibility, high efficiency and the advantages that other similar equipment can not replace. It avoids the limitation of lathe, drilling machine or manual tapping, and saves time, labor, not easy to rot teeth, taps are not easy to break and so on. Its remarkable characteristics are widely praised and adopted by users. This machine is suitable for all machinery manufacturing industries, and now customers cover machine tools, mold machinery, plastic machinery, printing machinery, packaging machinery manufacturer, construction machinery, automotive and motorcycle parts, aeroengine, locomotive and rolling stock, tobacco machinery and general machinery industries.
Breaking of automatic tapping machine is a common failure. The common reasons are as follows:
1. The feeding speed of the automatic tapping machine is too fast, which makes the torque too large. Therefore, the manufacturer generally suggests that the speed of the automatic tapping machine should not exceed 100 revolutions per minute when the ordinary tap is used to process the thread.
2. The size of the bottom hole of the automatic tapping machine does not match the tap. This situation has greatly increased the tapping cutting part of tapping, and made the tap break easily.
3. The concentricity of automatic tapping machine is not enough. The starting position of the tap is not clear enough, and the torque is too large during the tapping process, which causes the tap to break.
4. The cutting fluid used by the automatic tapping machine is misused or is not used. A lot of heat is generated in the whole process of tapping. Then the tap is broken.
5, the operator's fault. For example, when the blind hole thread is processed, when the tap is about to contact the bottom of the hole, the operator does not realize that the tap breaks, which requires the staff to strengthen the sense of responsibility.
