Due to the taper interference and clamping force, as the tool is clamped there will be slight radial expansion of the spindle. The amount of expansion is dependent on the amount of interference, the clamping force, and design of the spindle. Technical Manual Upon request, engineering support and estimations of spindle expansion can be provided for individual designs. kennametal.com C33 KMT_KM4X_Catalog_C032_C033_EN.indd 33 L V i KMT KM4X C l C032 C033 EN A 31 2016 9/1/16 5 44 PM2:02 PM
