toolholding 18 high speed and high velocity machining concentricity and balance the critical criteria for selection of tooling for higher speeds are concentricity and balance concentricity toolholding tools should be selected based on there ability to hold the tool concentric to spindle rotation this normally results in tools that are friction driven such as collet chucks shrink fit holders power milling chucks hp chucks etc balance the effect that a lack of balance will have on a cutting operation is relative to the type of cutting forces generated in the cut the higher the cutting forces the less effect balance will have on the overall operation of the machine tool under most circumstances a pre-balanced holder is all that is required to achieve a balanced machining condition selecting the proper tool holder type for higher speed applications er collet chuck for most drilling and lighter higher speed milling applications very good concentricity and very good balance safe opera
