How to choose aluminum alloy tapping oil? In order to avoid rotten teeth stained and easy to clean!
January 10, 2022
There is a customer of volatile aluminum alloy tapping oil. They mainly make various sheet metal products, many of which require drilling and tapping. The material is basically aluminum, mainly 1060 aluminum. In the tapping workshop, there are some older uncles and aunts. Young people are reluctant to do this, because they are too dirty, they have to brush a little aluminum tapping oil on the tap, and then drill and tap the tap. In the past, the use of engine oil to stain chips was more serious because of the lack of extreme pressure and insufficient lubricity. Therefore, the texture and accuracy of the tapped teeth are slightly worse. The key is that it also affects their efficiency and thus affects the piece rate. There is also a lot of oil residue, and the viscosity is too high, so the cost of subsequent cleaning is also high. For the boss, of course, he wants to improve efficiency and reduce costs in every aspect. Therefore, he thought of replacing professional aluminum. Try alloy tapping oil.
The hardness of aluminum alloy material is very low, and the melting point is also low. When the temperature of the tooth hole rises slightly, generally at 50-80 degrees, the material softens and approaches the melting point. When using extrusion wire tapping, the torque and friction are very Large (torque is four times that of cutting), it will generate a lot of heat energy, the temperature in the hole will rise, and it is easy to reach the melting point of materials such as aluminum alloy. At this time, the thread extruded by the tap is easy to It softens and falls off and sticks to the wire tap, so when tapping, we often see aluminum chips sticking to the wire tap, which is a normal phenomenon in this case. Choosing a suitable tapping oil can solve the above problems to a certain extent. Remember not to use the so-called tapping oil that looks very viscous to attack these materials, such as machine oil, or some waste oil on other machine tools, the effect is not good, because there is no corresponding additive added, so One function or several of them are missing. It is necessary to choose some special tapping oils with low viscosity, good extreme pressure, good cooling and good chip removal function.
