There are many kinds of classification methods for diamond engineering drill bits, and the common ones are as follows:
1, according to the use of classification engineering drilling engineering construction for its main use, this kind of engineering drilling specifications are many, the largest amount, has formed a special series of industrial drilling to drilling, cored for its main purpose, mainly used in the processing of products, such as wide screen wide lens cut material, silicon wafer nesting material. Sample drill is mainly used for material sampling analysis, such as large graphite electrode, firebrick analysis.
2, according to the classification of its manufacturing method, hot pressing method is similar to the hot pressing manufacturing process method of geological pregnancy insert drill. A ring can be made first and then welded to the steel body, or directly hot pressed to the steel body. Electroplating method is similar to electroplating drill manufacturing process. Electroplating method can be divided into epitaxial growth and conventional method.
3, according to the classification of the diamond used natural diamond engineering drill with high quality natural diamond as cutting grinding material, mostly used in building materials, construction industry. Artificial diamond engineering drill is made of high quality artificial diamond single crystal, which is used in optical and chemical industries.
