The machine parts industry is inseparable from processing accuracy, but do you know what is processing accuracy? The following is by Billion lerideBring a detailed interpretation of machining accuracy!

    Machining accuracy is the degree of conformity between the actual size, shape and position of the surface of the machined part and the ideal geometric parameters required by the drawing. The deviation between the actual geometrical parameters and the ideal geometrical parameters of the part is called the machining error. Machining accuracy can be roughly divided into four types: dimensional accuracy, shape accuracy, position accuracy, and mutual relationship.

    Dimensional accuracy
    Refers to the degree of conformity between the actual size of the machined part and the center of the tolerance zone of the part size, the ideal geometric parameters, for the size, is the average size.
    Shape accuracy
    It refers to the degree of conformity between the actual geometry of the surface of the processed part and the ideal geometry, for the surface geometry, it is absolute circle, cylinder, plane, cone and straight line.
    Position accuracy
    Refers to the actual position accuracy difference between the surface of the workpiece after processing, for the mutual position between the surface, is absolute parallel, vertical, coaxial, symmetrical and so on.
    interrelation
    Usually, when designing machine parts and specifying the machining accuracy of parts, attention should be paid to controlling the shape error within the position tolerance, and the position error should be less than the dimensional tolerance. That is, the shape accuracy requirements of precision parts or important surfaces of parts should be higher than the position accuracy requirements, and the position accuracy requirements should be higher than the dimensional accuracy requirements.
