Axis workpieces are commonly used in the center hole for positioning processing. The central hole commonly used in machining is specified by the national standard GB145-85. Since the standard center hole positioning surface is a 60° cone surface, it is also called a surface contact center hole. When machining or detecting high-precision rigid shaft workpieces, the surface contact center hole is used as the positioning reference, and its precision is limited, which often cannot meet the processing or inspection accuracy requirements. In actual processing, a so-called line contact center hole appears. The line contact center hole is based on a standard center hole, changing its geometry or shape so that the contact between the center hole and its matching tip is positioned to become a line. Ideally, a closed positioning curve is formed between the center hole and the tip - the positioning circle. The shaft type workpiece is positioned by the line contact center hole, and the machining precision is greatly improved, and the manufacturing thereof
