Radial runout testing equipment
In machining, to ensure the quality of the processed products, it is necessary to test the processed products to see if the error is within the tolerance range. Only within the range of the runout tolerance can the processed products be qualified, otherwise it is unqualified. Radial runout is used to detect the deviation of shaft parts, check the roundness of the shaft at a certain point and the deviation of the shaft relative to the datum line.
Definition of radial runout:
Radial runout is used to detect the shaft deviation, check the roundness of a certain point on the shaft and the deviation relative to the datum line. Radial runout is divided into radial circular runout and radial total runout.
Radial circle runout: the tolerance zone of radial circle runout is in any measuring plane perpendicular to the datum axis, the radius tolerance value is t, and the center of the circle is in the area between two concentric circles on the datum axis, and its tolerance zone is limited in the range of two side three knife coordinates (plane coordinates).
Radial total runout: the radial total runout tolerance is the area between two cylindrical surfaces whose radius difference is t and is coaxial with the datum axis, and its tolerance zone is limited in the range of three coordinates (spatial coordinates).
Any circle can not be without any error, more or less a little error, a few wires or even a few microns, but the naked eye can not see, need to use tools to measure!
