Drilling tool manufacturers tell about the correct use of mine drilling tools
After decades of development, the production of drilling tools has made great progress. The application of drilling tools in mine production is relatively wide. On this basis, further analysis and understanding of the production status and development direction of mining drilling tools are The progress and quality improvement of steel drilling tools will have effect and significance. Drilling tool manufacturers will tell you the correct use of mine drilling tools.
When the drill bit and the drill rod are in use, first check whether the drill tail is flat, whether the taper tip and the taper hole meet the requirements, whether the cutting edge of the drill bit is damaged, whether the water hole is accessible, whether the wind pressure and water pressure are sufficient Etc.; the alloy collision between the drill bits is strictly prohibited. When you start drilling, you should pay attention to the light wind, that is, the wind pressure should be lowered first, and the wind pressure can be gradually adjusted to normal after the drilling is stable. For the selection of drill rod, the drill rod should ensure sufficient mating surface with the drill bit. Generally, the depth of the drill rod inserted into the drill bit should be ≥25mm, and the contact surface should be as large as possible, not less than 60%. Therefore, try to choose drill rods that are machined with a taper tip. The drill rod used in conjunction with the drill bit should ensure that it is straight by naked eyes, and the impact end of the drill tail should be flat.
The service life of mine drilling tools is determined by the internal quality of the product itself and the scientific method of use. The quality of the product itself is inferior, no matter how carefully and scientifically it is used, it will not play a role. On the contrary, no matter how good the product is, If you do it carelessly and do not use it in accordance with the scientific method, it will also be scrapped in advance, and it will not work.
In summary, the application of drilling tools in mines has brought great help to the mining industry. During the use of drilling tools, in order to ensure the use of the role, we need to use them correctly and operate them correctly. In the process of using the product, mastering the knowledge of the product can bring great help to the development of the industry.
