There are many classification methods of diamond engineering drill bits. The most common methods are as follows:
1. Classification by use Engineering drills are mainly used for engineering construction. These types of engineering drills have many specifications and the largest amount of use. A special series of industrial drills has been formed. Drilling and coring are the main uses, mainly used for products In the processing, such as the material of wide-screen wide-lens, the nesting of silicon wafers, etc. The sample drill is mainly used for sampling and analysis of materials, such as the analysis of large graphite electrodes and refractory bricks.
2. According to its manufacturing method, the hot pressing method is similar to the hot pressing manufacturing method of the geologically impregnated drill bit. A ferrule can be made first and then welded on the steel body, or it can be directly hot-pressed on the steel body. The electric ballast method is similar to the process method for the manufacture of electric ballast drill bits. Electric ballast method can be divided into epitaxial growth method and conventional method.
3. According to the classification of diamonds used, natural diamond engineering drills use high-quality natural diamonds as cutting materials, which are mostly used in building materials and construction industries. Synthetic diamond engineering drills use high-quality synthetic diamond single crystals as cutting materials, and are mostly used in the optical and chemical industries.
