The characteristics of 'geometric tolerances' that serve as a standard for indicating processing accuracy.

Introduction to the characteristics of geometric tolerances, which are effective standards for achieving high precision.

To manufacture and process according to customer requests, it is necessary to have design capabilities to shape those requests, along with high-precision technology that faithfully realizes that design. One effective criterion for judging whether processing is being carried out faithfully to the design is the characteristics defined by geometric tolerances. Geometric tolerances are divided into four categories: "shape," "orientation," "location," and "runout," with 19 types of characteristics established. 【Shape Tolerances】*Indicates the accuracy of geometric shapes. ■ Straightness - Whether the center of the processed item, generatrix, etc., is accurate as a straight line. ■ Flatness - Whether the surface of the processed item is flat and free of undulations. ■ Roundness - Whether the curvature of the circular part of the processed item is accurate as a circle. - Includes shaft parts and conical processed items. ■ Cylindricity - Indicates the degree of accuracy of cylindrical processed items. ■ Profile of a line - The minimal distortion in the line part that indicates the contour of the processed item. ■ Profile of a surface - The minimal distortion in the surface part that indicates the contour of the processed item. *For more details, please refer to the external link or feel free to contact us.
