[0002] The hub of a car is the part of the wheel where the axle is installed, also known as the "rim" or "steel rim". It is a cylindrical metal part with the inner profile of the tire supporting the tire and the center mounted on the axle. The holes on the hub can be used to install and fix various parts, such as tires, brake system parts, sensors, etc. The design and processing accuracy of these holes are crucial to ensure the correct installation and stable operation of the parts.
