Holes and even cutting research field

Small diameter hole finishing techniques, because of its wide range of applications, the importance and difficulty of processing high, has been a hole processing and even cutting research field content. American hole processing technology, also known as  abrasive wheels , the use of diamond or cubic boron nitride abrasive grains produced by the electroplating honing tools, honing technology compared with the conventional,  grinding wheel  accuracy, shorter  Diamond blade time, fewer skills and lower processing costs, and therefore the future precision hole processing technology is an important development direction. However, research in this country is still very limited, there are some problems.
