The processing quality of hardware accessories banana plugs includes processing precision and surface quality. Machining accuracy is the degree to which the three geometric parameters of the actual size, shape, and position of the surface of the processed part conform to the ideal geometric parameters required by the drawing. The deviation of the actual geometric parameters of the part from the ideal geometric parameters is called the machining error.
Machining accuracy and machining error are both terms used to evaluate the geometric parameters of the machined surface. The greater the machining accuracy is, the greater the tolerance level is. The smaller the level value, the higher the accuracy. The machining error is expressed by a numerical value. The larger the numerical value, the greater the error. High machining accuracy means small machining error, and vice versa, the actual parameters obtained by any machining method will not be absolutely accurate. From the perspective of the function of the part, as long as the machining error is within the tolerance range required by the part drawing, it is considered that the machining accuracy is guaranteed.
The quality of the machine depends on the quality of the parts, the quality of processing and the quality of the assembly of the machine. The machining quality of parts already includes two parts, machining accuracy and surface quality. Machining accuracy refers to the degree to which the actual geometric parameters of the part after machining conform to the ideal geometric parameters. The difference between them is called machining error. The size of the machining error reflects the level of machining accuracy. The greater the error, the lower the machining accuracy, and the smaller the error, the higher the machining accuracy. The main aspects that affect the machining accuracy include dimensional accuracy, and the degree of conformity between the actual size of the processed part and the center of the tolerance zone of the part size.
Position accuracy refers to the actual position accuracy difference between the relevant surfaces of the parts after processing. The items evaluated as positional accuracy include parallelism, perpendicularity, inclination, coaxiality, symmetry, and position. The position degree is controlled by the position tolerance. The position tolerance of each item is also divided into 12 accuracy levels. Generally, when designing machine parts and specifying the machining accuracy of parts, care should be taken to control the shape error within the position tolerance. And precision parts or important surfaces of parts, the shape accuracy should be higher than the position accuracy requirements, the position accuracy requirements, and the position accuracy requirements should be higher than the dimensional accuracy requirements.
