Let's learn about Button Bit
In rock drilling operations, the quality of the drill tool determines the efficiency of the operation and also determines the service life of the drill tool. Therefore, the reasonable use of the drill tool can improve our operating efficiency. After all, the rock drill is a power output device, and the drill tool is what really deals with and contacts the rock. There are many types of drill tools, and different drill bits have different characteristics. Today, Gaea will talk about how to use the button bit reasonably.
As the name implies, the working surface of the button bit is a spherical metal, and it is distributed on the entire surface of the bit like human teeth, unlike the button bit which is a straight-line alloy. This type of drill tool itself has the characteristics of being more wear-resistant than other types of drill bits, but in order to use it more reasonably, you still need to pay attention to some matters. First, don't think that you can ignore it just because it is wear-resistant. Any drill tool needs to be monitored at all times. Once an abnormality is found, it can continue to be used if it is repaired in time to extend its service life. The button bit is no exception. We must always pay attention to whether it shows "cracks" or peeling. When this happens, it means that the wear of the drill tool has affected its use and needs to be repaired. When the drilling speed of the rock drill drops significantly, we must also consider that it may be due to excessive wear of the drill tool. Second, do not use brute force during the operation. Reduce the thrust to reduce the stress on the button bit, and use a large amount of water to flush it to remove impurities generated during the operation in time. Attention should also be paid to the use of flushing water. Flushing should be continued and started in advance when the operation just begins. Otherwise, the temperature of the drill tool will rise and then suddenly cool down when it encounters water, causing cracks.
