[0002] In the production of mechanical parts, cylindrical grinders are often used to process various cylindrical and conical outer surfaces. They are suitable for processing shaft parts with small batches and high precision requirements in general precision machining workshops.

[0003] Most of the existing external cylindrical grinders currently grind cylinders or cones by grinding the side surface of the grinding wheel. However, when encountering the inclined surface of the cone, the grinding wheel of the external cylindrical grinder is in linear contact with the inclined surface of the cone, thereby reducing the grinding efficiency of the cone during grinding. When the grinding wheel is in linear contact with the cone, it is easy to cause over-grinding of the object to be grinded, thereby reducing the grinding quality of the cylindrical product. Secondly, the length of the products ground by the existing external cylindrical grinder is generally short, thereby reducing the scope of use of the external cylindrical grinder.
