Do you know what end and radial runout of an electric spindle are?
End runout refers to the vertical movement of the spindle’s end face during rotation. Excessive end runout can result in uneven machined surfaces. Controlling end runout ensures surface flatness.
Radial runout refers to the side-to-side oscillation of the spindle during rotation. Excessive runout can cause a machined cylinder to appear elliptical. Controlling radial runout ensures roundness and cylindricity.
