[0002] Circular saw blades are highly efficient tools widely used in metallurgy, machinery, stone processing and other industries. The finishing of the inner hole and outer circle is an important process that affects the accuracy of circular saw blades. According to the different types of circular saw blades, there are various rough processing methods for the inner hole and outer circle of circular saw blades, such as laser cutting, plasma cutting, flame cutting, shearing, turning, etc., but the finishing is mainly done by fine turning. For medium and large circular saw blades, the commonly used fine turning equipment is generally a milling machine. The receiving plate is installed on the workbench, and the circular saw blade is placed on the receiving plate. After tightening, the inner and outer circles are turned;
