Combining offset printing presses explains what are mechanical parts, components, and mechanisms?

The parts are the smallest unit of the components. The parts can be processed one by one. For example, the paper suction nozzles and bolts in the paper suction components can be manufactured with different processing methods and processing equipment.

The component is composed of several parts. There is no relative movement between these parts, but there is relative movement with other components or parts. Therefore, the component is the smallest unit of motion, such as the part of paper suction in the paper feeding device. It is The part is composed of paper suction nozzles, fixing bolts and rubber bands.

The mechanism is composed of a number of components (or parts) with a fixed relative movement between them, the main role of which is to transfer or change the form of the movement. For example, the separation mechanism can convert the rotational motion into a planar linear motion.
