Precision components refer to mechanical components that meet high standards in terms of dimensional accuracy, shape accuracy, positional accuracy, and surface roughness. They are typically used in equipment or systems that have strict requirements for operational accuracy, stability, and reliability
The core differences between it and ordinary parts are mainly reflected in three aspects,
First, the accuracy standards are different. The dimensional tolerances of precision parts can usually reach the level of 0.001-0.01 millimeters, and the shape errors (such as flatness and roundness) and position errors (such as parallelism and perpendicularity) are also much lower than those of ordinary parts.
The second is the difficulty and process of processing. Precision parts require high-precision machining equipment (such as five axis machining centers, slow wire cutting machines) and special processes (such as precision grinding, electrical discharge machining). Among them, slow wire cutting utilizes pulse discharge between the electrode wire and the workpiece, achieving a cutting accuracy of 0.001 millimeters. Ordinary parts can be processed by conventional lathes and milling machines, and the machining accuracy of ordinary lathes is generally between 0.01-0.1 millimeters.
Thirdly, the application scenarios are different. Ordinary parts are mostly used for non core parts such as structural support and simple transmission, while precision parts directly affect the core performance of the equipment.
