Partial explanation: The extrusion tap is due to the plastic flow of the material, and the extrusion is transformed into a screw thread. The performance of the cutting fluid must be based on lubricity greater than cooling. In addition, in the way of oil injection, the oil film should not be lost at the part where the tap and the female thread are in contact, and the oil should be fully forced.
Is it necessary to use tapping oil for tapping? There are many factories that encounter tapping in metal processing, but most of them do not use tapping oil, or use other oils instead of tapping oil. Many factories have even used it for more than ten years, and they have already gotten used to it and feel that there is no problem. No problem is often the biggest problem, because you have never used real tapping oil and feel that the status quo is the best. That's because you have no comparison, no comparison, and often better solutions are outside your field of vision. If you can't see the long-term, you will lose more. Maybe you don't think there is any problem at the moment. Once there is a problem It may be fatal and catch you off guard.
Let me first talk about the benefits of using tapping oil for tapping. Many people have tapped teeth by hand, and they all know that the teeth that have been tapped with oil will have a high finish and a high degree of thread engagement. Tapping Refueling has become common sense for everyone, but if you really understand why tapping needs refueling, the operators must not be very clear. In fact, there are three main purposes of refueling for tapping. A good tapping oil will expel machining debris. It comes out, that is, the chip removal performance mentioned by many people is better, especially for some processing materials with poor chip removal performance.
Based on these points, the tapping oil cools down during the tapping process. When the tap is cutting, the temperature of the tap rises sharply. If it is not cooled, the tap is easily damaged, which will cause the strength of the tap to drop sharply. Affect the durability of the tap, and the second is lubrication. When the tap is cutting, if no oil is added, the surface of the cut thread is prone to roughness and not smooth. Seriously affect the quality of the thread. The third is chip removal. During the tapping process, a large amount of iron filings (here mainly cutting taps) will be produced. Iron filings are easy to stick to the threaded hole and the tap. At this time, permeability is indispensable. processing accessories.
It is better to use tapping oil for tapping processing. Don’t be fooled by those cheap oils. The most important thing is to use the right oil, which is beneficial to processing. Jingshen Lubricating Oil is a cutting fluid manufacturer with quality and services are guaranteed.
